FRIDGE !
Oh no.....just woke up... fridge temperature after a good night of sleep is now... MINUS 4°C instead of PLUS 4°C !!
Okay I set the temlperature knob at 6 on a scale of 7 as a starting point to then adjust as required but hell, even then, should not be THAT cold in there !
So I progressively, slowly turn the knob to a lower / hotter setting and... no go, the compressor doesn't want to stop !
This new / NOS replacement thermostat is kaput ! All that work to try to get it to fit. 3+ weeks running my home made timer ... for nothing !
Can't afford to buy a 20 Euros brand new one, I mean a "fresh' one not 20+ year old stock, so I will try that mechanical timer daddy just sent me.
Fridge was working just fine with a fixed duty cycle of 25%, running 15 minutes every hour, so will do that again.
Might buy a fresh thermostat once I find a job... or not, because we all know there is nothing more permanent than a temporary fix that works....
No, I don't think it's a wiring issue, been studying the thing and the fridge for long enough, and the defrost mode and light work just fine. This thermostat is just kaput.
