The short answer
A M cooler that runs but will not get cold is usually losing its heat rejection or its door seal, not its compressor. The table below carries two model codes for this family, close enough in build that the layout described here holds across both.
What you observe on these models
- The cabinet is warmer than the setting and the unit is clearly running — Heat is being moved but not enough of it. Airflow, seal or load, in that order of likelihood on a compact cabinet.
- The outside of the cabinet or the back is hot to the touch — Normal to a point — that is where heat leaves. Too hot to hold usually means the condenser cannot shed it into the room.
- Condensation or sweating on the inside of the door — Warm humid air is getting in. That is a seal or a door-closure problem, and it also explains the temperature.
- The unit is silent and nothing is cold — A different fault: no power, a failed start relay, or a thermoelectric module that has stopped.
- Only part of the cabinet is warm — Air is not circulating inside. Overpacked shelves and blocked internal vents do this and are fixed by unloading, not by a part.
Causes, most likely first on the M family
- The condenser cannot shed heat — dust, or too little clearance — First, and most often a placement problem rather than a fault: these cabinets need clear air at the back and the sides, and they are frequently installed where they do not get it.
- The door is not sealing, or is being held open by the load — Second. A bottle standing proud of a shelf, or a door that is not swinging fully closed because the cabinet is not level, produces exactly this.
- The thermostat setting, or a mode the unit is in — Cheap to rule out and easy to get wrong on a control with few markings.
- The cabinet is overpacked and air cannot circulate — Common right after a restock, and it resolves by unloading rather than by repair.
- The sealed system or the compressor has failed — Last. Reach it only when the four checks above are clean, because it is the one candidate that ends in a decision about replacing the unit.
Check in this order, and why
- Pull the unit out and look at the back — Clear dust from the coil with a brush and a vacuum, and give the cabinet clear air at the back and sides.
- Test the door seal with a sheet of paper — Close the door on a sheet at several points round the frame.
- Check the setting and put a thermometer inside — A refrigerator holds food safely at 40 °F (4 °C) or below; a freezer compartment needs 0 °F (−18 °C) or below.
- Unload the cabinet and leave the vents clear — Leave a gap at the back wall and around any internal vent.
- Listen at the back with the room quiet — A compressor that hums and stops after a few seconds is a start-relay symptom; steady running is normal; silence with a warm cabinet points at power or the control.
Models in the M family — Each code here is pinned to a single build, so match the tag inside your door frame character for character.

Before you open anything
Safety
Unplug the unit before cleaning the coil or reaching behind the cabinet; a capacitor can hold a charge after the power is off. The tubing at the back is the sealed system — never drill, bend or cut it, and never try to top up refrigerant yourself.
When to call a technician
Clearance, coil cleaning, the door seal, the setting and the load are owner checks and they settle most warm-cabinet calls on a compact cooler. The line is the sealed system: if the coil is clean, the unit has air, the door seals and the cabinet is still warm, the remaining candidates are the compressor, the start relay and a refrigerant loss.
