What you are actually seeing
- The fresh-food compartment is warm but the freezer is still cold
- Both compartments are warming together and slowly
- Both compartments are at room temperature and nothing is running
- Not this fault: Warm only after a big shop or a hot day
Ranked causes on a COMMERCIALCOOL refrigerator
- Defrost cycle not clearing the evaporator — Ranked here because: many of these cabinets defrost by cycling the cold plate rather than by a timed heater, so frost management is an owner responsibility and a first suspect
- Cold control or thermostat out of calibration — Ranked here because: the cold control is a mechanical capillary thermostat on most of the range, so it fails as a discrete, testable part
- Condenser coil fouled with dust, lint or grease — Ranked here because: these units get slid into tight alcoves and under counters with no clearance, which is the single most common installation error on the platform
- Blocked air path between freezer and fresh-food compartment — Ranked here because: a compact cabinet has so little thermal mass that loading and door habits change its behaviour more than they would on a full-size machine
What to check, and in what order
- Put a thermometer in each compartment and read both after an hour
- Confirm the compressor and the condenser fan are running and that air is moving inside the freezer
- Clear the freezer and look at the rear wall and the vents between the compartments
- Unplug the cabinet, pull it out and clean the condenser coil and the condenser fan thoroughly
Steps you can safely do yourself
- Clear the freezer and look at the rear wall and the vents between the compartments — Tools: none — Estimated time: about ten minutes
- Unplug the cabinet, pull it out and clean the condenser coil and the condenser fan thoroughly — Tools: vacuum, coil brush — Estimated time: about half an hour
- Close the door on a strip of paper at several points around the frame and pull each one out — Tools: sheet of paper — Estimated time: a few minutes
- If there is a frost slab, unplug the cabinet with the doors open for a full day, then run it and watch how long normal cooling lasts — Tools: towels — Estimated time: a full day
- Put a thermometer in each compartment and read both after an hour — Tools: two appliance thermometers — Estimated time: about an hour

When to call a technician
the condenser is clean, the fans run, the doors seal and the cabinet still will not cool — that is a sealed-system diagnosis the defrost fault returns after a manual defrost, since the heater and thermostat are behind the evaporator the compressor runs continuously and the compartment is hot rather than merely warm
