What you are actually seeing
- A sheet of frost on the rear wall of the freezer
- Cold spots and warm spots in the same compartment
- The fresh-food compartment is warm but the freezer is still cold
- Not this fault: Warm only after a big shop or a hot day
Ranked causes on a Conserv refrigerator
- Door not sealing or being left ajar — Ranked here because: the full-height door on an all-refrigerator or upright freezer is tall and heavy enough to drop on its hinges, and alignment is the first thing to check
- Defrost cycle not clearing the evaporator — Ranked here because: a good part of this range is manual or low-frost rather than fully frost-free, so frost build-up is expected behaviour that becomes a fault only when it is ignored
- Condenser coil fouled with dust, lint or grease — Ranked here because: these cabinets are frequently built into cabinetry that does not give them the clearance the platform assumes
- Blocked air path between freezer and fresh-food compartment — Ranked here because: how the machine is loaded and dosed changes its behaviour more than most owners expect
What to check, and in what order
- Close the door on a strip of paper at several points around the frame and pull each one out
- 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
- 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
Steps you can safely do yourself
- Put a thermometer in each compartment and read both after an hour — Tools: two appliance thermometers — Estimated time: about an hour
- Confirm the compressor and the condenser fan are running and that air is moving inside the freezer — Tools: none — Estimated time: a few minutes
- 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

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
