I put a thermometer in the freezer compartment last night. Showing -21 degrees C. The fridge is at 3 degrees just now but doesn’t last at that temp for long. It will creep up to 9 or 10 before the fridge kicks on again.
Many thanks Dave! I’ve finally managed to get the cover off…..what a job! I’m gonna pull the fridge out today (It’s integrated) and look for any other potential faults. Could you possibly talk me through testing the stat with a multimeter??
