The answer first
Start outside the cabinet. A refrigerator that shows nothing at all is usually behind a tripped breaker, a switched-off socket, a damaged cord or an extension lead that was never rated for it, and every one of those is checkable in a few minutes with nothing but your eyes and another appliance. What follows is arranged by likelihood rather than by how interesting each cause is.
What this looks like from the outside
- No interior light, no display and no sound at all — Nothing anywhere means the cabinet is not being fed, which is a wall-side question first.
- The light works but nothing runs — Power is arriving, so the fault is inside: a control board, a relay or a start device rather than the socket. If you can only do one check, make it this one.
- The breaker trips when the cabinet is plugged in — Tripping on connection is a fault with a safety dimension, and repeated resets are how it gets worse. Mention it when you book a visit; it changes which parts a technician brings.
- It ran until the cabinet was moved or cleaned — A plug part out of its socket, a cord pinched under a foot, or a supply lead damaged in the move: all common and all visible. A result here decides whether the next two checks are worth doing at all.
Likely causes, ordered
- No power at the socket — It leads the list because it is the most common and the cheapest to eliminate, since one working lamp plugged into the same outlet answers it. A cause in this position is worth eliminating before you spend anything.
- A failed main control board or its supply fuse — Below the mechanical causes because boards outlast cords and relays on most cabinets, but it does happen, and it presents as total silence with a live socket. That single observation eliminates more of the list than any amount of guessing.
- A thermostat or temperature control turned fully off — Low on the list but free to check, and it explains the cases where nothing is wrong at all. Treat the ordering as a route through the possibilities rather than as a prediction.
- A failed compressor — Last.
The diagnostic order
- Plug a lamp or a kettle into the same socket — This separates the appliance from the supply in under a minute, and it is the check most often skipped. It needs nothing you do not already own.
- Listen at the back for a click every few minutes — A regular click with no run is a start-device pattern and it changes the diagnosis completely. Eliminate it properly before moving down; a half-checked cause comes back later.
- Remove any extension lead and plug straight into the wall — Extension leads are the weakest part of most installations, and a refrigerator draws a surge at every start that finds their weak points. Give it a moment rather than glancing; the thing you are looking for is not always obvious.
Steps you can do yourself
- Reseat the plug firmly and check it for heat marks — Pull it, look at the pins for discolouration, and push it fully home. Leave the machine a few minutes afterwards before you decide it has not helped.
About 10 min
- Remove extension leads and adaptors from the circuit — Plug the cabinet directly into a wall socket and try again. Many dead cabinets are healthy appliances behind a failed lead. This is the cheapest information available on the machine.
About 10 min
- Turn the temperature control fully on and wait — Set it to a mid position rather than the coldest, give it several minutes, and listen for the compressor starting. If it does not change anything, that result is still worth recording.
About 15 min
- Stop at this point: what follows needs a meter on a live circuit — What is left is diagnosis rather than inspection, and diagnosis needs instruments.
Before you open anything
Safety
Cut the supply at the breaker, then check that the machine is genuinely dead before reaching in. The power being off is not the same as the machine being safe to touch immediately. Refrigerant work is licensed work: a line opened without the right recovery gear vents the charge and turns a repair into a replacement. Work with the door mechanism intact rather than around it.
When this becomes a service call
Draw the line here: if the answer is outside the cabinet you can find it yourself; if it is inside, the next step needs a meter and that is not an owner tool. A technician draws the same line, for the same reasons. Call promptly if frost or water keeps returning after you have cleared it, because something is still feeding it.
