Cooling Issue — Compressor Runs But Products Warm
This diagnosis is for when the cooling unit is running, but the dispensed products are not reaching the expected cold temperature.
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.
- Frost covering entire evaporator in thick layer: note-and-continue
- Compressor making unusual noises: stop-and-escalate
- Because this involves the sealed refrigeration system, any investigation into the compressor or cooling cycle must be performed by a qualified technician.
- Do not attempt to service the refrigerant lines or compressor components; contact a qualified technician immediately.

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 by circulating refrigerant through a compressor-condenser-evaporator cycle with forced-air distribution.
- 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.
