In short
A refrigerator that shows no sign of life is almost never a dead compressor — it is a supply problem, a start component or a control that has stopped waking the compressor up. The first two checks need no tools and settle most of these cases. Anything that turns out to be on the sealed system is a service call. A licensed cooler is a generic compact platform with a badge, and it should be diagnosed as the generic platform it is. The first two steps cost nothing at all.
What you actually see
- A short buzz at the back and nothing else — The compressor is being asked to start and is stalling against pressure or a bad winding.
- No interior light, no display, no hum — The cabinet is completely inert when you open the door.
- The light works but nothing ever runs — Control power is present and the cooling circuit never starts.
- NEAR MISS: it runs constantly and is simply not cold — That is a cooling fault, not a start fault, and it is a different page.
The causes in order of likelihood
- Undersized supply, extension lead or converter — First, and first for a reason. It leads on a licensed cooler because the chassis is built for a consumer cord-set and a clean outlet, and it behaves badly on anything less. A long lead, a shared outlet or an inverter that sags under starting current leaves a small cabinet clicking, with no fault inside the appliance at all.
- No usable power at the outlet or the cord — Second. A tripped breaker, a failed outlet, a damaged cord-set or a switched socket someone turned off.
- Start relay or capacitor failure — Third. The relay drops the start winding in and out. When it fails the light works, control power is normal and the compressor only clicks.
- Main control board not calling for cooling — Fourth. The board decides whether the compressor runs at all, and one that has lost its output leaves everything else looking healthy.
- Body: These are ordered for this brand and appliance rather than for the appliance class in general, and the ordering is qualitative.
The diagnostic order
- Try the outlet with something you know works — A lamp or a phone charger settles the supply question in seconds and rules out the single most common cause.
- Open the door and watch the interior light — Light with no running means control power is fine and the fault is downstream; no light at all sends you back to the supply.
- Listen at the back for a click on a repeating cycle — A regular click with no start is the start relay signature and it separates relay from board without any tool.
- Body: The order below moves from free checks to paid ones and stops before anything that needs a meter on live terminals.
What you can do now
- Plug something else into the same outlet — If it does not work either, the fault is the outlet or the breaker and not the appliance.
- Take the appliance off any extension lead or power strip — Run it direct from a wall outlet for an hour and see whether it starts.
- Reset the control: unplug, wait several minutes, plug back in — A supervisor board that has latched an error frequently clears on a genuine power cycle rather than a quick one.
- STOP if the next step means testing a relay or a winding — That is a meter on live terminals and it is where the owner-side work ends.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. The start relay and compressor terminals stay dangerous after the cabinet goes quiet.
When this becomes a service call
Call once the outlet is proven good and the cabinet still does nothing, and call immediately if the plug or cord shows heat damage, if the breaker trips, or if the compressor hums and never starts. Sealed-system work is licensed work. Move perishable food somewhere cold first, then deal with the appliance.

This page is written for the appliance class rather than for one Bud Light family or model line. Where a family- or model-specific page exists for your unit it is the more specific answer and should be preferred over this one; the brand and appliance hub linked below routes to everything more specific that exists today.
