Re: lec t450cw wont work after defrost?
The only way to test is with a multi-meter to check the supply through the stat and compressor really.
It will most likely be the thermostat but if you are unsure then have a look in Repairs@ for a local engineer.
Just a thought….I hope your lil’ sister didn’t defrost it with anything sharper than her elbow???
If you have a go yourself then don’t forget to completely unplug the appliance as a first step :zap:
