The short answer
A Cosmo refrigerator that shows no lights, no fan and no compressor is nearly always a supply problem rather than a dead cabinet. Kitchen outlets behind a large appliance are rarely checked and frequently shared, and a demonstration or showroom mode can silence a cabinet completely. Check power and mode before anything else.
What you are actually seeing
- No interior light, no fan and no compressor — Means: on-page
- The interior light works but nothing runs — Means: on-page
- The display is lit but the cabinet never cools — Means: on-page
- The cabinet stopped after a power cut — Means: on-page
- The cabinet works when plugged into a different outlet — Means: on-page
- The cabinet runs but does not get cold — Means: different-fault — Go to: cosmo-refrigerator-cooling-failure
- A code on the display with the cabinet running — Means: different-fault — Go to: cosmo-refrigerator-control-fault
- Body: Match what you see before you take anything apart. No interior light, no fan and no compressor. The interior light works but nothing runs. The display is lit but the cabinet never cools. The cabinet stopped after a power cut. The cabinet works when plugged into a different outlet. Some near-miss symptoms belong on a different page: The cabinet runs but does not get cold points at a cooling or airflow fault, covered on cosmo-refrigerator-cooling-failure; A code on the display with the cabinet running points at a control fault, covered on cosmo-refrigerator-control-fault.
Causes, ranked for this machine
- No power at the outlet, a tripped breaker or a GFCI that has tripped behind the cabinet — Why this rank: First because the outlet behind a large appliance is the least inspected in the kitchen and is often shared
- A demonstration, showroom or sabbath mode left set — Why this rank: Produces a lit display and a cabinet that will not cool, and it survives a power cut on many controls
- The temperature control set to off or to its warmest position — Why this rank: Free to check and easily done while cleaning or restocking
- A damaged or pinched supply cord behind the cabinet — Why this rank: Common when a cabinet has been pushed back into a tight opening
- A failed control board, start relay or compressor — Why this rank: Last because it needs a part and everything above it is free
- Body: Ranked for a household refrigerator with an electronic control, forced-air cooling shared between the compartments, an automatic defrost cycle and a condenser at the base. Most likely: No power at the outlet, a tripped breaker or a GFCI that has tripped behind the cabinet. First because the outlet behind a large appliance is the least inspected in the kitchen and is often shared. Next most likely: A demonstration, showroom or sabbath mode left set. Produces a lit display and a cabinet that will not cool, and it survives a power cut on many controls. Third: The temperature control set to off or to its warmest position. Free to check and easily done while cleaning or restocking. Fourth: A damaged or pinched supply cord behind the cabinet. Common when a cabinet has been pushed back into a tight opening. Fifth: A failed control board, start relay or compressor. Last because it needs a part and everything above it is free.
What to check, in order
- Prove the outlet is live with a lamp before anything else
- Check the breaker and any GFCI serving the kitchen
- Read the control for a demonstration mode or an off setting
- Look behind the cabinet for a pinched or damaged cord
- Body: Each check rules out the causes above it. First, prove the outlet is live with a lamp before anything else. Second, check the breaker and any GFCI serving the kitchen. Third, read the control for a demonstration mode or an off setting. Fourth, look behind the cabinet for a pinched or damaged cord.
Checks you can safely make yourself
- Unplug the cabinet and plug a lamp into the same outlet to prove it is live, then plug the cabinet back in — Tools: lamp — Time estimate: a quarter of an hour
- Check the breaker and any GFCI serving the kitchen and reset once only — Tools: none — Time estimate: a few minutes
- Read the control panel and the manual markings for a demonstration or showroom indicator, and clear it — Tools: none — Time estimate: a quarter of an hour
- Set the temperature control to a mid position and listen for the compressor or the fan to respond — Tools: none — Time estimate: a few minutes
- Pull the cabinet forward carefully and look at the cord where it passes behind, checking for pinching or damage — Tools: torch — 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 outlet to prove it is live, then plug the cabinet back in. Tools: lamp. Time: a quarter of an hour. Step two: Check the breaker and any GFCI serving the kitchen and reset once only. Tools: none. Time: a few minutes. Step three: Read the control panel and the manual markings for a demonstration or showroom indicator, and clear it. Tools: none. Time: a quarter of an hour. Step four: Set the temperature control to a mid position and listen for the compressor or the fan to respond. Tools: none. Time: a few minutes. Step five: Pull the cabinet forward carefully and look at the cord where it passes behind, checking for pinching or damage. Tools: torch. Time: a quarter of an hour.
Safety first
Safety
Unplug the cabinet before moving it or inspecting the cord, and do not move a full cabinet alone: a loaded refrigerator is a heavy-appliance move. 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. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. fridge-40f unplug-before-service
Where the owner fix ends
Call a technician when the outlet is proven live, the breaker holds, no demonstration mode is set, the control is on and the cord is undamaged, and the cabinet is still dead. The remaining causes are the control board, the start relay and the compressor, all behind panels with mains terminals.
