What you are actually seeing
- Temperature fine in winter and poor in summer
- A cabinet that recovers after a defrost and fails again in days
- Not this fault: Warm after a large load of unfrozen food went in
Ranked causes on a Conservator freezer
- Evaporator fan stopped on a frost-free upright — Ranked here because: this platform is mechanical by design, so wear parts and couplings fail as parts rather than as symptoms of a board
- Cold control or sensor out of calibration — Ranked here because: the temperature control is a mechanical thermostat, which either makes contact or does not — it is a quick, decisive check
- Door or lid not sealing — Ranked here because: these machines are commonly installed by the owner or the delivering dealer, and levelling and venting errors are the most frequent finding
- Condenser coil or compartment fouled — Ranked here because: a coil that cannot reject heat produces every symptom of a failing system while nothing has actually failed
- Room temperature outside the design range — Ranked here because: the room the machine lives in is part of the machine as far as its control is concerned
- Frost build-up blocking airflow or the door — Ranked here because: a simple machine gives the owner more ways to load and dose it wrong, and those show up as faults
What to check, and in what order
- Give the cabinet clearance at the back and the sides and check the room temperature
- Empty the cabinet, unplug it and let it defrost completely, then run it and watch how long normal performance lasts
- Put a thermometer in the middle of the load and read it after an hour, then again the next day
- Close the door or lid on a strip of paper at several points and pull each one out
Steps you can safely do yourself
- Put a thermometer in the middle of the load and read it after an hour, then again the next day — Tools: appliance thermometer — Estimated time: about an hour, then a day of watching
- Close the door or lid on a strip of paper at several points and pull each one out — Tools: sheet of paper — Estimated time: a few minutes
- Look at the frost: how thick, and where it is concentrated — Tools: flashlight — Estimated time: a few minutes
- Unplug the cabinet, pull it clear and clean the condenser coil and its compartment — Tools: vacuum, coil brush — Estimated time: about half an hour
- Give the cabinet clearance at the back and the sides and check the room temperature — Tools: tape measure, room thermometer — Estimated time: about a quarter of an hour

the cabinet is sealed, clean, defrosted and clear and still will not reach temperature performance decays again within days of a full defrost, which points at the defrost circuit the compressor runs continuously with a warm cabinet
