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 Conserv freezer
- Door or lid not sealing — Ranked here because: a single-function cabinet is opened and loaded harder than a combination unit, and the gasket carries the whole load of keeping one compartment at one temperature
- Frost build-up blocking airflow or the door — Ranked here because: with no ice maker in the cabinet the defrost drain is the only water path, so any water at all points at it
- Cold control or sensor out of calibration — Ranked here because: the cold control on most of the range is a discrete mechanical part, testable and replaceable on its own
- Condenser coil or compartment fouled — Ranked here because: these cabinets are frequently built into cabinetry that does not give them the clearance the platform assumes
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
