If your fridge is not turning on, the internal light does not work, the display is dead, the compressor will not start, or you only hear clicking or buzzing, the fault may be linked to the power supply, socket, plug, fuse, thermostat, start relay, control board or compressor start circuit. London Appliance Repair provides specialist fridge not turning on repair in London for domestic fridges and fridge freezers.
Power supply checks
Socket, plug, power cable, internal fuse and main circuits can be inspected.
Compressor start diagnosis
Start relay, overload, capacitor, control board and compressor circuit can be checked.
London service
Repair support for fridges that do not switch off across many London areas.
Why Is Your Fridge Not Turning On?
A fridge not turning on is different from a fridge that is not cooling. When a fridge is not cooling, the appliance is usually powered but not producing enough cold air. When a fridge will not turn on, there may be no light, no display, no sound and no response from the appliance at all.
Sometimes the problem is simple, such as a loss of power, a faulty socket or a loose plug. In other cases, the fault may involve an internal fuse, wiring, thermostat, temperature sensor, electronic control board, start relay, overload protector or the compressor itself.
This page explains the most common fridge not turning on scenarios based on what you can see or hear. Those symptoms help a technician begin the fault diagnosis in the right place, rather than playing electrical guesswork with a large cold cupboard. Humanity has done enough of that.

5 Common Situations When a Fridge Will Not Turn On
A fridge that will not turn on does not always have one single cause. Sometimes the appliance is completely dead, sometimes the light works but the compressor does not start, and sometimes there is clicking or buzzing. These small differences can change the diagnosis completely.
1. No light, no sound and no response at all
When the fridge is completely dead, the power supply path usually needs to be checked first. A faulty socket, loose plug, damaged power cable, blown internal fuse, broken circuit or failed main control board can stop power reaching the appliance.
2. The light is on but the compressor does not run
If the internal light works but there is no cooling and the compressor does not start, power is reaching the appliance but the start command or start process is failing. The thermostat, temperature sensor, control board, start relay or compressor may be involved.
3. The fridge clicks or buzzes but will not start
Repeated clicking is often linked to a failed attempt to start the compressor. The start relay, overload protector, start capacitor or compressor may be faulty. A buzzing sound without successful compressor start can point to compressor strain or a locked compressor.
4. The fridge ran for a while, then switched off and will not restart
If the fridge was working before but then switched off and no longer starts, the fault may involve the thermal overload, compressor overheating, a refrigerant leak, a short circuit in an internal component or a failed control board.
5. The fridge will not turn on after a power cut or voltage surge
A voltage surge when power returns can damage the electronic control board, internal fuse, start relay or compressor start circuit. Modern fridges are often more sensitive to voltage spikes, so the control board should be tested with suitable tools.
Electric shock and short circuits
Internal fridge components operate with mains power and sensitive circuits.
Wrong part diagnosis
Clicking, buzzing or total power failure can be caused by several different parts.
More appliance damage
Incorrect compressor, board or relay testing can increase the final repair cost.
Specialist tools required
Voltage, relay, overload and compressor checks should be carried out with proper equipment.
- Important safety note
Why Should You Avoid Opening Fridge Electrical Panels Yourself?
A fridge that will not turn on often involves mains power, the control board, compressor or start circuit. Opening panels, testing components directly or moving wires without the correct tools and training can cause electric shock, short circuits, board damage or further compressor failure.
Check the household power
Check whether other appliances in the same part of the property are working.
Look at the plug
Make sure the plug has not become loose or been pulled out during cleaning or moving the appliance.
Listen for sounds
Clicking, buzzing or complete silence can all help identify the likely fault path.
Mention power cuts or surges
If the issue started after a power cut or voltage surge, mention this when booking the repair.

What Should You Check Before Calling a Fridge Engineer?
Only carry out simple and safe checks. If these do not solve the problem, avoid opening panels or testing internal parts. Electricity and a dead fridge are not a poetic combination, unless the poem is titled “expensive mistake”.

FAQs About a Fridge Not Turning On
The cause may be the incoming power supply, socket, plug, cable, internal fuse, main control board or start circuit.
In this case, power is reaching the appliance, but the thermostat, temperature sensor, control board, start relay or compressor may not be operating correctly.
Repeated clicking is often linked to a failed compressor start attempt and may involve the start relay, overload protector, capacitor or compressor itself.
Yes. A voltage surge can damage the electronic control board, internal fuse, relay or compressor start circuit.
If the fridge has no response, the internal light is off, the compressor will not start, it clicks or buzzes, or it will not turn on after a power cut, it is best to have the appliance inspected.
