The short answer
Dead is easier than warm. On a built-in cabinet whose supply often runs through a switched spur behind the cabinetry, a cabinet showing no sign of life is nearly always a power-path fault, and the distinction that matters early is whether the interior light works: light without cooling and no light at all point in opposite directions.
What you are actually seeing
- No light, no fan, no hum — The cabinet shows no sign of power at all. Start at the wall, not at the appliance.
- The interior light works but nothing cools — Power is arriving. The fault lies past it, in a control, a sensor or a start component.
- A short hum, then a click, repeating every few minutes — The compressor is trying to start and an overload is protecting it. This is a start-component pattern and a commonly repairable one.
- The cabinet died after a storm or an outage — Suspect the supply, a protected outlet, or a control that took a surge. Sequence matters: what changed is the best clue you have.
- Not this fault: it runs continuously and stays warm — That is a cooling failure with a completely different ranking. Use the cooling page for this cabinet.
- Not this fault: the display is lit but unresponsive — A locked or frozen control panel is a control fault rather than a power fault, and it often clears with a power cycle.
Causes, most likely first on this machine
- The outlet, breaker or protected socket — First, always: it costs nothing to rule out, it is the single most common cause, and it is the one that makes people pay a call-out fee to be shown a reset button.
- The power cord or its inlet — Second: cords get crushed behind cabinets, pinched under rollers and pulled at the plug. The damage is usually at one of those three places and usually visible.
- The main control board, or a failed thermostat — Third: the machine has power and never calls for cooling. It is a real fault, it needs a meter to confirm, and it is much cheaper than what most people fear.
- The start relay or the run capacitor — Fourth, and the cause behind the hum-and-click pattern: the compressor cannot reach running speed, its overload protects it, and the cycle repeats.
- The thermal overload itself — Fifth: an overload failed open leaves a dead compressor that is otherwise healthy, which is why it must be ruled in before anyone condemns the sealed system.
- The compressor — Last: a seized compressor is real, but it is the least likely cause and nobody should reach it before the five above.
Check in this order, and why
- Prove the outlet with something else — A lamp or a phone charger answers in seconds what guessing cannot. Do this before touching the cabinet at all.
- Check the breaker and any protected outlet in the run — Protected outlets trip quietly and often sit behind or above the cabinet where nobody looks.
- Look along the whole cord and at the plug — Crush damage behind the cabinet and heat damage at the plug are both visible without tools.
- Note whether the light works, and listen for hum and click — This free test tells a technician more than anything else you could report.
- Stop before start components and controls — Everything past this point is a meter on live terminals or a capacitor that may still hold a charge.
What an owner can safely check
- Test the outlet with a known-good appliance — A lamp is ideal. If the lamp is dead, the cabinet was never the problem.
Tools: table lampAbout 5 min
- Reset the breaker once, and reset any protected outlet on the circuit — Once. A breaker that trips again is telling you something, and repeated resets are how a fault becomes a fire.
About 10 min
- Inspect the cord, then unplug and replug firmly — Look for flattening, cuts and discoloured pins. A hot-smelling plug means stop and call, not re-seat.
About 10 min
- Record the pattern for whoever comes — Light or no light, hum and click or silence, and what changed the day it stopped. Half a minute of notes shortens the visit.
About 5 min
- Stop here if the next step needs a meter on live terminals — Start relays, capacitors, overloads and boards all sit at line potential, and a capacitor can hold a charge after the power is off.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off, and that is exactly the component this fault points at. Do not reset a breaker repeatedly; a breaker that trips again is protecting the circuit from something real. Never work on a cabinet standing in water, and do not run one through an extension lead or a daisy-chained adapter while diagnosing it, which adds a second fault to the one you are chasing. If a plug or cord smells hot or shows scorching, stop there.
When to call a technician
Call once the supply is proven and the cabinet is still dead, and call straight away if a breaker trips again when reset, if anything smells of burning, or if the compressor hums and clicks repeatedly. That last pattern is repairable and its parts are inexpensive, but confirming which of three components failed takes a meter on live terminals inside the cabinet — which is where this stops being owner work.

What this page does not cover
This page covers the appliance class under this nameplate rather than one family or model line. Terminal layouts, relay types, board part numbers and the resistance values a technician measures all differ by platform and belong on the model-specific page linked below where one exists. House wiring faults beyond the outlet are an electrician's work and are not covered here.
