Compressor Not Running — Refrigeration Check
This basic diagnostic checks if the cooling unit's main component is receiving power and attempting to operate, guiding the user toward a simple fix or a specialized service call.
Qualified technician handoff: stop before live electrical testing, sealed-system refrigeration work, compressor service, or protected-compartment access unless a qualified technician is handling the work.
- Stop work on refrigeration. Possible sealed-system leak. Requires licensed technician. Do not puncture any lines.
- Allow compressor to cool. Do not repeatedly restart. Escalate to licensed technician if issue persists.
- Because this involves live-voltage and refrigeration components, you must escalate to a qualified technician.
- If the compressor does not cycle after cooling down, a qualified technician must diagnose the sealed-system components.

Where to find this
Use this as orientation before touching the machine. It is location help, not a repair instruction.
Start at the affected product shelf or selection row; compare the tray, coil, and product path with a nearby working selection.
- Maintains product temperature within target range using a compressor-based forced-air cooling cycle.
- Compressor
- Condenser coil and fan
- Evaporator coil and fan
Do not open sealed-system or compressor areas unless a qualified refrigeration technician is handling the work.
