Thanks Dave that helps alot.
Just a question about the defrost system in this freezer.
The defrost element is connected in series with this little black component (rectangular plastic) that is clipped to the evaporator coils. I thought this was the defrost limit switch thermostat but its plastic and doesnt look like ones i have seen on the web.
NEUTRAL--------I Black thing I--------------element------------LIVE
The live and neutrals go to a connector block that i think connects to the PCB.
There is also a white torpedo shaped device embedded in the coils with brown and blue wires connecting to the same connector block. These must go off to the PCB as well.
What i am confused about is which is the defrost sensor? Is the white object the defrost thermostat, if so what is the black thing?!
How much are these two parts and do you know how much a replacement PCB is?
Also, you say it is a Brandt made appliance, do you by any chance know if there is a Brandt model number also; as the one i have must be an MFI model number?
Thanks so much for your help!
