The short answer
A Cotlin compact refrigerator that is completely dead is nearly always a supply problem, because these cabinets are plugged into whatever socket was nearest and are moved far more often than a full-size appliance. Check the socket, the lead and the dial, and if the cabinet has just been transported, let it stand upright before switching it on.
What you are actually seeing
- No light, no hum and no response at any dial setting — Means: on-page
- The light works but the compressor never runs — Means: on-page
- The cabinet stopped working after being moved — Means: on-page
- It works on one socket and not on another — Means: on-page
- A click every few minutes with nothing else happening — Means: on-page
- The cabinet runs but nothing gets cold — Means: different-fault — Go to: cotlin-refrigerator-cooling-failure
- The dial makes no difference at any setting — Means: different-fault — Go to: cotlin-refrigerator-control-fault
- Body: Match what you see before you change anything. No light, no hum and no response at any dial setting. The light works but the compressor never runs. The cabinet stopped working after being moved. It works on one socket and not on another. A click every few minutes with nothing else happening. Some near-miss symptoms belong on a different page: The cabinet runs but nothing gets cold points at a frost or ventilation fault, covered on cotlin-refrigerator-cooling-failure; The dial makes no difference at any setting points at a control or thermostat fault, covered on cotlin-refrigerator-control-fault.
Causes, ranked for this machine
- No power at the socket, a switched socket, or a shared strip that has tripped — Why this rank: First because a compact cabinet is plugged in wherever there is a socket, often behind furniture where nobody looks
- The dial set to off or to its warmest position — Why this rank: Free to check and easily knocked while loading the cabinet
- The cabinet switched on immediately after being transported, particularly if it was laid down — Why this rank: Compacts are carried and moved far more than full-size cabinets, so this is a real cause
- An extension lead too light for a compressor start — Why this rank: A lead that runs a lamp perfectly can be marginal for a motor start
- A failed thermostat, start relay or compressor — Why this rank: Last because it needs a part and on a compact cabinet the repair is rarely economic
- Body: Ranked for a compact cabinet with a static cold-plate evaporator, no circulating fan and no automatic defrost, where frost on the plate is the dominant failure mode rather than anything mechanical. Most likely: No power at the socket, a switched socket, or a shared strip that has tripped. First because a compact cabinet is plugged in wherever there is a socket, often behind furniture where nobody looks. Next most likely: The dial set to off or to its warmest position. Free to check and easily knocked while loading the cabinet. Third: The cabinet switched on immediately after being transported, particularly if it was laid down. Compacts are carried and moved far more than full-size cabinets, so this is a real cause. Fourth: An extension lead too light for a compressor start. A lead that runs a lamp perfectly can be marginal for a motor start. Fifth: A failed thermostat, start relay or compressor. Last because it needs a part and on a compact cabinet the repair is rarely economic.
What to check, in order
- Prove the socket with a lamp and check for a wall switch
- Set the dial to a mid position and listen for the compressor
- Plug the cabinet directly into a wall socket rather than a strip or a lead
- If the cabinet has just been moved, stand it upright and wait before switching on
- Body: Each check rules out the causes above it. First, prove the socket with a lamp and check for a wall switch. Second, set the dial to a mid position and listen for the compressor. Third, plug the cabinet directly into a wall socket rather than a strip or a lead. Fourth, if the cabinet has just been moved, stand it upright and wait before switching on.
Checks you can safely make yourself
- Unplug the cabinet and plug a lamp into the same socket to prove it is live, and check whether a wall switch controls it — Tools: lamp — Time estimate: a quarter of an hour
- Turn the dial slowly through its range and listen for the compressor to start — Tools: none — Time estimate: a few minutes
- Plug the cabinet directly into a wall socket with no extension lead or strip in the path — Tools: none — Time estimate: a few minutes
- If the cabinet has recently been transported, stand it upright and leave it for a period before switching it on — Tools: none — Time estimate: a wait of several hours
- Stand at the back and listen for a click repeating every few minutes, which is a failing start attempt rather than a dead cabinet — Tools: none — Time estimate: a quarter of an hour
- Body: Checks an owner can make with the cabinet unplugged or simply observed. Step one: Unplug the cabinet and plug a lamp into the same socket to prove it is live, and check whether a wall switch controls it. Tools: lamp. Time: a quarter of an hour. Step two: Turn the dial slowly through its range and listen for the compressor to start. Tools: none. Time: a few minutes. Step three: Plug the cabinet directly into a wall socket with no extension lead or strip in the path. Tools: none. Time: a few minutes. Step four: If the cabinet has recently been transported, stand it upright and leave it for a period before switching it on. Tools: none. Time: a wait of several hours. Step five: Stand at the back and listen for a click repeating every few minutes, which is a failing start attempt rather than a dead cabinet. Tools: none. Time: a quarter of an hour.
Safety first
Safety
Unplug the cabinet before moving it or inspecting the lead, and do not run a compressor appliance through a light extension lead. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. A refrigerator holds food safely at 40 °F (4 °C) or below.

Where the owner fix ends
Call a technician, or replace the cabinet, when the socket is proven live, the cabinet is plugged in directly, the dial produces no compressor response anywhere in its range and the cabinet has stood upright. A repeated click points at the start relay or the compressor, and on a compact cabinet that is usually where replacement becomes the honest answer.
