Hello,I have this problem where the cabinet runs ok when first switched on but once it has cycled on the controller doesn't come back on.
Powering the unit off & then On Resets the PCB
& it works

I read that it could be a defrost problem.
I checked temp sensors reading 5.8K impedance i reckon it's ok
I checked thermal fuse for continuity OK
I checked defrost heater(stuck to the plastic tray) reading 8.4k impedance ,is this ok????
Is the defrost heater the problem???
could be the pcb???

thanks for your help in advance

Hi

The defrost heater is the problem.

Replaced Defrost heater and now the behavior is as follow:

the cabinet runs ok when first switched on but once it has cycled on
the controller doesn't come back on.

I read that ...once in defrost mode if the appliance doesn’t reach +17oc on the freezer evaporator the unit will stay in defrost mode.

Next morning and with the freezer been defrosted itself the fridge start working again.

Summing up, fridge get cold, defrost itself, gel cold, defrost itself......

Any suggestion will be much appreciated.

Thanks in advance
