Hello everyone,
During a storm several months ago, we lost power in my rural location for 3 days. I didn’t realise until the third day that the power wasn’t actually completely gone, there was around 60 to 70V line to neutral.
I realised I’d unplugged everything except my brand new fridge freezer. It wasn’t working, but the compressor was really hot to the touch.
Since then, the temperature is erratic. Bottom shelf which is supposed to be around 1c can go from 5c to -3c. It ruins the veg and fruit in the veg drawer, they freeze and are no good afterwards.
I bought a temperature datalogger which not only shows the ups and downs as a sawtooth wave, but it’s odd as one week can be close together waves, the following week more erratic temp swings and further apart waves. Sometimes the temps are quite normal for days, then suddenly high or low temps happening sporadically. Even in the middle of the night when the door isn’t being opened.
It also started making funny noises after the power cut. Sometimes it sounds like gravel being dropped on the floor in the kitchen, or little stones being dropped one after another.
Other times almost a bang or clunk. It can make sharp sounds like a twig snapping.
Does anyone know what is likely to be the problem please?
That is a very strange one and I doubt anyone has come across that circumstance before so there’s unlikely to be a quick and easy answer.
If I were to guess, from what you describe, I’d think it was some sort of mechanical issue in the refrigerant system but that is a best guess. If it were electronic I’d expect it to do a thing and stick with it if that makes sense.
That said, the sensors can cause all sorts of weird things to go on with those units but I can’t see how a power failure etc could cause one of those to fail.

I can only think that almost 3 days of 70V going into it has caused some damage. Or maybe voltage spikes have harmed the electronics?
Here are some temperature logs I took, first one is the lowest shelf of the fridge compartment. Second is the middle freezer drawer. Each is about 3 weeks of logging and shows what I think seem odd behaviours?:
