Fridge door maintenance that keeps the cold in.
The door is the part of a fridge that is used most and wears first. Seals, hinges, handles and alignment decide how much cold escapes, how much power the fridge uses and whether frost and water build up inside.
Why the door matters.
Every time a fridge door opens, warm damp air rushes in. A door that closes properly and seals all the way round keeps that to a minimum. A door that sags, rubs or no longer grips lets air leak in all day, and the compressor runs longer to make up for it.
Most door problems start small: a seal that has gone hard, a hinge that has loosened, a shelf bin that drags on the frame. They are quick and inexpensive to put right early, and much more costly once frost, water and a tired compressor are involved.
Seals and gaskets.
The rubber seal around the door has a magnet or a flexible lip that presses against the cabinet. Over the years it hardens, cracks, tears or collects grease, and the grip weakens. We clean seals that can be saved and fit a seal made for your model when they cannot.
A new seal only works if the door sits square. We adjust the door as part of the job, so the new seal closes evenly on every side and the fridge does not frost up again.
Hinges, alignment and handles.
Heavy door shelves, children swinging on doors and years of use pull hinges loose and drop the door slightly. The door then rubs one side and leaves a gap on the other. We tighten or replace hinges, level the fridge, adjust the door and refit handles that have worked loose or broken.
On side-by-side and French door fridges, two doors have to meet each other as well as the cabinet. We check the alignment between them, because a small mismatch there lets in a surprising amount of warm air.
Shops, restaurants and display fridges.
Doors on display fridges, bottle coolers and commercial units open hundreds of times a day. Door closers, magnetic strips, hinges and heater strips around the frame wear fast, and a door that is left ajar for a few hours can cost a whole day of stock.
We service door closers and seals on a schedule that fits your opening hours, and we can do the work before opening or after closing. A planned visit costs far less than losing a shelf of drinks or dairy.

Questions people ask
How do I know if my fridge door seal needs replacing?
Close the door on a sheet of paper and pull it out. If it slides out easily, the seal is not gripping there. Test several points around the door. Frost near the door, water on the outside of the cabinet and a fridge that never stops running are other signs.
Can a door seal be cleaned instead of replaced?
Sometimes. Grease and spilled sugar stop a seal from gripping, and warm soapy water can restore it. If the rubber is hard, cracked or torn, it needs replacing.
Why does my fridge door not close properly?
Usually a loose hinge, a door that has dropped slightly, an uneven floor, a full door shelf that drags on the frame or a seal that has swollen. We find which and fix it.
Do you maintain doors on shop fridges and display coolers?
Yes. We service door closers, seals and hinges on display fridges, bottle coolers and commercial units, and can visit before opening or after closing.
Good to know about your fridge.
Saving power with the fridge you already have
A fridge runs all day and every day, so small improvements add up. Set the fridge between about three and five degrees and the freezer at minus eighteen. Colder settings use more power without protecting the food any better.
Keep the condenser clean, leave air space around the fridge and keep it away from the cooker and direct sun. Check the door seal and do not leave the door open while you decide what to eat.
A full fridge holds its cold better than an empty one, so a few bottles of water on the shelves help in a fridge that is mostly empty. Do not overpack it, though, because the air must still move. If a fridge is very old and the compressor is struggling, a replacement may repay itself in power, and we will tell you honestly if that applies.
Inverter fridges explained
A traditional compressor switches fully on and fully off. An inverter compressor changes its speed to suit the cooling needed. It runs slowly most of the time, which is quieter and uses less power, and it speeds up when the fridge needs to cool down.
To do that it needs a control board, called the inverter board, that converts the power and drives the compressor. The board is the weak point, because it dislikes surges and heat. When a board fails, the compressor does not start, even though the compressor itself may be fine.
That is why we test the board, the wiring and the compressor separately. A board can sometimes be repaired and sometimes needs replacing with a matching part. A voltage guard and a clean condenser are the best protection for an inverter fridge.
What happens on a visit
You call or WhatsApp us with what the fridge is doing and a photo of the model sticker. We tell you when a technician can come and how the visit fee works. The technician arrives, listens to the fridge, measures the temperature in both sections and checks the obvious causes in order.
When the fault is found, you are told what it is, shown the worn part where possible and given the full price for parts and labour before anything is changed. Nothing is done without your agreement. If a part has to be ordered, we tell you how long it will take.
After the repair, the fridge is left running and checked to confirm it is pulling down to temperature. Before we leave, we explain what failed and how to avoid it next time. If the fridge is not worth repairing, we say so, and we can collect an old fridge for responsible recycling.
How a fridge actually keeps things cold
A fridge does not make cold. It moves heat. Inside the sealed pipework there is a refrigerant gas. The compressor squeezes the gas, which makes it hot, and the hot gas flows through the coil at the back or underneath, called the condenser, where it gives its heat to the room. The gas turns to a liquid, passes through a very thin tube that drops its pressure, and arrives in the cold coil inside the fridge, the evaporator, where it turns back to a gas and soaks up heat from the food. Then it returns to the compressor and the cycle repeats.
That is why the back of a fridge feels warm and why a fridge squeezed into a cabinet struggles. If the heat cannot leave, the cycle slows and the compressor runs for longer. It is also why gas does not get used up: it travels round in a closed loop. When a fridge is low on gas there is a leak, and the leak has to be found and sealed first.
In a no-frost fridge a fan blows air over the evaporator and into the compartments, and a small heater melts the frost off the coil a few times a day. Most cooling faults come from these supporting parts, the fan, the heater, the sensor and the board, long before the compressor itself fails.
Reading the rating plate inside your fridge
Almost every fridge has a sticker or metal plate inside, usually on a side wall or at the back of the fridge compartment. It tells a technician almost everything: the brand, the model number, the voltage and frequency, the type of gas the fridge uses and how much of it, and often the manufacturing date.
Take a clear photo of that plate before you call. With the model number we can check which thermostat, seal, fan or board fits, which saves time on the visit. The gas type matters too. Modern fridges often use R600a, a flammable gas used in small amounts, while older ones commonly use R134a. The two are not interchangeable, and a fridge must always be charged with the gas printed on its own plate.
If you cannot find the plate, look for a sticker behind the vegetable drawers, on the inside of the door frame or on the back of the cabinet. Send us whatever you can find and the brand, and we will help you identify the model.
