The short answer
A Coyote refrigerator that runs without cooling is almost never the compressor, whatever the noise suggests. On this class the fault is usually blocked clearance or recirculated warm air around the cabinet, with an ambient temperature outside what the unit was designed for next to rule out, and both are visible to an owner in minutes.
What you actually observe
- It holds temperature at night and loses it every afternoon — A daily cycle that tracks the sun points outside the cabinet.
- The cabinet is warm while the unit is clearly running — The compressor hum is there and the air inside is not cold, which rules out a dead unit immediately.
- NEAR MISS: only the ice maker has stopped while the food stays cold — That is an ice-production fault and it is a separate page with a separate cause list.
The causes, most likely first on this brand
- Blocked clearance or recirculated warm air around the cabinet — Every unit is rated for a gap above and behind it. Ranked first on a Coyote unit: an outdoor unit lives in a masonry or cabinet enclosure, and an enclosure built without the specified vent openings turns every warm day into a failure.
- An ambient temperature outside what the unit was designed for — Cooling capacity is specified against a room temperature band. Ranked second here: it is rated for outdoor use within a band, and a closed patio in full sun sits outside that band more often than owners expect.
- A condenser coil smothered in dust, lint or pet hair — Ranked third here: the coil takes in pollen, cooking grease and insects that no indoor coil ever sees.
- A door gasket that no longer seals — Ranked fourth here: a door seal worked by sun and frost hardens years before an indoor one would.
Check in this order, and why this order
- Feel the air coming out of the grille or off the back — Exhaust that is markedly warmer than the room, in a space with no gap, is the whole answer.
- Measure the air temperature where the unit actually stands — A reading well outside a normal room is the answer before anything is opened.
- Look at the coil at the back or behind the lower grille — A visible mat of dust, or a coil that is hot along its whole length with the fan running, confirms it.
What an owner can safely check
- Pull the unit out and restore the gap the installation calls for at the back and above — Also check that nothing is stored on top of a freestanding unit or stuffed behind it.
About 20 min
- Give the unit shade, ventilation or warmth as the case requires and re-check over a full day — Treat this as a diagnosis, not a repair: a unit in the wrong place fails the same way every summer.
About 30 min
- STOP HERE if the next step needs a meter on live terminals or a panel off — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Unplug the unit or switch off its breaker before any panel comes off: a capacitor can hold a charge after the power is off. Leave the door switch wired as it is, because it cuts the fan for a reason. Never chip ice off an evaporator with a tool, since the refrigerant tubing runs directly behind it.
When to call a technician
Call once the owner checks come back clean, or the moment the evidence points at the sealed system: refrigerant work is licensed work. Call immediately if you smell burning or see oil at the compressor, because that means the system is open and every further running hour makes the repair worse. Bear in mind when you decide that an outdoor-rated unit is built into an enclosure, and pulling it is the largest part of the job.

What this page does not cover
This page covers the Coyote refrigerator as a class, not one family or model line. What changes from build to build, meaning wiring colours, component test values and part numbers, is deliberately not here. Where a family or model page exists for your unit, it is the more specific answer and the one to read first.
