Fridge Freezer Not Cold Enough What to Do in Addlestone

Published September 2026 | Fridge Freezer Repair

We asked our Appliance Repair engineers the questions Addlestone homeowners ask most. If your fridge freezer has stopped keeping things cold, you're in the right place - this guide covers everything from quick checks you can do yourself to knowing when it's time to call a professional.

Why has my fridge freezer suddenly stopped being cold enough?

A fridge freezer that's lost its cooling ability is one of the most common call-outs our engineers handle across Addlestone and the wider Surrey area. The causes range from something as simple as a door seal that's gone slack to a failing compressor that needs full replacement.

The most frequent culprits our engineers find are:

1. Dirty condenser coils - these are usually at the back or underneath the appliance and get clogged with dust over time, which stops the fridge shedding heat properly.
2. A faulty door seal - if warm air is leaking in, the appliance has to work much harder and often can't keep up.
3. Blocked evaporator fan - this circulates cold air around both compartments. If it's iced over or broken, cooling drops off quickly.
4. Low refrigerant - less common in domestic units but it does happen, particularly in older appliances.
5. A failing thermostat or temperature sensor - the appliance may think it's colder than it actually is.

Before you call anyone, do a quick visual check. Is the fridge stuffed full? Is it sitting too close to a wall or a heat source like an oven? Both of these can reduce efficiency significantly. Our engineers use the Voltrade GoFIX diagnostic tool to pinpoint the exact fault before touching anything, which saves homeowners money on unnecessary part replacements.

My freezer is working fine but the fridge section is warm - what's going on?

This is a really telling symptom and our engineers see it regularly in Addlestone homes. When the freezer is cold but the fridge isn't, it almost always points to one of two things: a blocked or failed evaporator fan, or an issue with the air damper that controls how much cold air flows from the freezer compartment into the fridge section.

Most modern fridge freezers - whether you've got a Bosch, a Samsung, or a Beko - use a single evaporator coil and a fan to push cold air into both sections. If that fan stops spinning, the freezer stays cold because it's closest to the coil, but the fridge warms up because it relies on airflow. In frost-free models, a failed defrost heater can cause ice to build up around the evaporator and block airflow entirely.

The fix depends on the fault. A replacement evaporator fan motor typically costs between 60 and 120 pounds for parts, plus labour. A new defrost heater is usually cheaper - around 30 to 70 pounds for the part. Neither is an enormous job for an experienced engineer, and it's nearly always worth repairing rather than replacing the whole appliance when this is the cause.

How do I check if my fridge freezer door seal is the problem?

A failed door seal is one of the easiest problems to diagnose yourself, and it's more common than people think. Over time, the rubber gasket around the door gets brittle, warped, or picks up mould that stops it sitting flush against the cabinet.

Here's how to check it. Close the fridge door on a piece of paper or a thin bank card. If you can pull it out without any resistance, the seal isn't gripping properly and warm air is leaking in. Repeat this test around all four edges of both doors. You can also shine a torch inside the closed fridge in a dark room and look for light escaping around the edges.

A worn seal makes the compressor run almost constantly to try to compensate. Your electricity bill goes up, the compressor wears out faster, and the fridge never quite gets to the right temperature. Replacement seals for popular brands like Hotpoint, LG, and Indesit typically cost between 25 and 60 pounds plus fitting. It's one of the better-value repairs you can have done. Some makes have proprietary fittings, so it's worth having an engineer source the right part rather than guessing online.

What does a faulty compressor actually mean, and is it worth fixing?

The compressor is the heart of your fridge freezer - it's the component that pressurises the refrigerant and keeps the whole cooling cycle going. When it fails, the appliance simply can't cool at all. You might hear it clicking or humming without properly starting, or it may have gone completely silent when it used to make a low hum.

Compressor failure is the most expensive repair a fridge freezer can need. A replacement compressor itself typically costs between 100 and 250 pounds depending on the brand and model, and that's before labour, which can add another 80 to 150 pounds. For a high-end Bosch or Samsung American-style fridge freezer, the repair often makes financial sense because the appliance could have another ten years of life in it. For a budget model that's already seven or eight years old, you'd often be better putting that money towards a new unit.

Our engineers are direct with Addlestone customers about this. There's no point spending 350 pounds repairing a fridge that cost 300 pounds new. The Voltrade GoFIX diagnostic process checks the compressor's start capacitor first, because a failed capacitor mimics compressor failure but costs far less to fix - sometimes as little as 20 to 40 pounds for the part.

Is frost building up inside my fridge freezer causing the problem?

Excessive frost build-up is a major cause of poor cooling and it's something our engineers see frequently in Surrey homes, particularly in older frost-free models where the defrost system has started to fail.

In a frost-free appliance, a small heater automatically melts any ice that forms on the evaporator coil during regular defrost cycles. If that heater fails, or if the defrost timer or thermostat controlling it gives up, ice accumulates rapidly. Eventually it blocks the evaporator entirely, and airflow through the fridge freezer drops to almost nothing. The appliance feels cold when you open the door because of the ice, but it can't actually circulate cold air properly.

If you suspect this is the issue, you can try manually defrosting the appliance. Switch it off, take everything out, and leave the doors open for 24 to 48 hours with towels on the floor to catch the water. If the fridge then works normally for a week or two before the problem comes back, that confirms the automatic defrost system has failed and needs repair. Replacement defrost components typically cost between 30 and 90 pounds depending on what's failed, which makes this one of the more economical fixes.

What temperature should my fridge and freezer actually be set to?

This question comes up more than you'd expect, and it's worth getting right. The Food Standards Agency recommends keeping your fridge at or below 5 degrees Celsius. Most engineers suggest aiming for 3 to 4 degrees as a practical target. Your freezer should sit at minus 18 degrees Celsius or colder.

Many homeowners in Addlestone run their fridges warmer than they should, either because the dial settings are confusing or because the thermostat has drifted over time. On older dials, higher numbers usually mean colder (more cooling), but this varies by brand - Samsung and LG models with digital controls are much clearer. If you're unsure, a cheap fridge thermometer from a hardware shop will give you an accurate reading in about 30 minutes.

If the thermostat dial is set correctly but the temperature is still wrong, the thermostat itself may have failed. Mechanical thermostats can be replaced relatively cheaply - typically 20 to 50 pounds for the part. Electronic control boards on newer models are more expensive, sometimes running to 100 to 200 pounds, but they're usually accurate when they're working.

Can I fix a fridge freezer myself, or do I need an engineer?

Some things are well within reach of a competent DIYer. Cleaning condenser coils, replacing a door seal, manually defrosting a blocked evaporator, and checking that the fridge isn't overcrowded are all things you can do without specialist tools. If the fridge is making a noise and you locate an obvious obstruction near the fan, removing that is also something you can tackle safely.

Where you need to stop and call an engineer: anything involving the refrigerant circuit, replacing the compressor, diagnosing electronic control board faults, or if you're dealing with a gas-based older system. Refrigerant handling requires specialist qualifications and equipment - it's not something to attempt at home. Similarly, if you're not confident working around electrical components, it's always safer to get someone in.

Our Addlestone engineers typically recommend having a professional diagnosis first if the appliance is under five years old, or if it's a premium brand where repair costs can be justified. A diagnostic visit usually costs between 50 and 80 pounds and will tell you definitively what's wrong and what the repair will cost, so you can make an informed decision.

How long should a fridge freezer last, and when is it time to replace rather than repair?

A well-maintained fridge freezer should last between 10 and 15 years. Budget models from brands like Beko or Hotpoint at the lower end of their range might give you 8 to 12 years. Premium appliances from Bosch, Miele, or Samsung's higher-spec lines can push well past 15 years with proper care.

The general rule our engineers apply is the 50 percent rule. If the repair cost is more than half the price of an equivalent new appliance, it's usually better to replace. So if your fridge freezer would cost 500 pounds to replace, a repair up to around 250 pounds is typically worth doing. Beyond that, you're often better off putting the money towards a new unit.

Age matters too. A compressor failure on a 12-year-old machine is a different proposition to the same fault on a 4-year-old one. An older appliance may also be significantly less energy-efficient than modern equivalents - some fridge freezers from 10 or more years ago use 30 to 40 percent more electricity than current A-rated models, so replacing them can cut running costs noticeably over time.

How much does fridge freezer repair typically cost in Addlestone?

Pricing varies depending on what's failed and which brand you have, but here's a realistic picture of what our engineers typically charge for common repairs in the Surrey area:

• Diagnostic visit: 50 to 80 pounds (usually deducted from repair cost if you go ahead)
• Door seal replacement: 80 to 150 pounds including parts and labour
• Thermostat replacement: 70 to 130 pounds including parts and labour
• Defrost heater or timer replacement: 90 to 160 pounds including parts and labour
• Evaporator fan motor replacement: 100 to 180 pounds including parts and labour
• Control board replacement: 150 to 280 pounds including parts and labour
• Compressor replacement: 200 to 400 pounds including parts and labour

Parts availability varies by brand. Bosch and Samsung tend to have good parts availability in the UK, which keeps waiting times down. Some less common imported brands can have lead times of one to two weeks for parts, which is worth factoring in if you're relying on the appliance daily.

How can I stop my fridge freezer losing its cooling ability in the future?

Preventative maintenance goes a long way. Our engineers find that most of the Addlestone call-outs they attend could have been delayed or avoided with a few simple habits.

Clean the condenser coils once a year - they're usually accessible from the back or underneath the appliance with the kick plate removed. A vacuum cleaner with a brush attachment does the job well. Check the door seals every six months for signs of cracking, mould, or warping, and wipe them down with warm soapy water to keep them pliable. Don't overfill the fridge - cold air needs to circulate, and a packed-solid fridge freezer can't do that properly.

Make sure the appliance has adequate ventilation. Most fridge freezers need at least a few centimetres of clearance on each side and at the back. Fitting one too tightly into an alcove is a common cause of overheating and premature compressor wear. If your fridge is in a garage or utility room that gets very warm in summer, be aware that most appliances are rated to operate up to around 32 to 38 degrees ambient temperature - beyond that, performance drops off.

Finally, if your fridge freezer is over ten years old and starts showing early signs of trouble - running more noisily than usual, occasional warm spots, slight condensation where there wasn't any before - it's worth having an engineer take a look before a small issue becomes a full breakdown. Catching a failing start capacitor early, for example, can save the compressor from burning out and avoid a much larger repair bill.

A fridge freezer that isn't cold enough is rarely a lost cause, especially when diagnosed early. Most faults affecting Addlestone homeowners - blocked airflow, worn door seals, defrost system failures - are repairable at a sensible cost. The key is knowing what you're dealing with before committing to a repair, which is why a proper diagnosis is always the right first step.

How long does a fridge freezer repair usually take in Addlestone?

Most common repairs - door seal replacements, fan motor swaps, thermostat faults - can be completed in a single visit lasting one to two hours. If a part needs to be ordered, there's typically a wait of two to five working days for standard brands like Hotpoint, Beko, and Samsung. Our engineers carry common parts for popular models.

Is it safe to eat food from a fridge that hasn't been cold enough?

If your fridge has been above 8 degrees Celsius for more than four hours, perishable foods like meat, fish, dairy, and cooked meals should be discarded. When in doubt, throw it out - the cost of food poisoning is far greater than the cost of replacing a few items. Keep a fridge thermometer handy so you always know the actual temperature.

Does my fridge freezer need to be Gas Safe registered to repair?

No. Gas Safe registration applies to gas boilers and gas appliances, not refrigeration. However, handling refrigerant gases in a fridge freezer does require F-Gas certification under UK law. Always check that your engineer holds the appropriate F-Gas qualification if the repair involves the refrigerant circuit - a reputable engineer will confirm this without being asked.

Why does my fridge freezer make a clicking noise and then stop cooling?

Clicking followed by a loss of cooling almost always points to the compressor struggling to start, usually because the start relay or start capacitor has failed. This is a relatively inexpensive fix - the relay or capacitor typically costs between 15 and 50 pounds - but it needs to be addressed quickly because repeated failed start attempts can cause the compressor itself to overheat and fail permanently.
