I have not used this freezer since but recently decided to attempt a diy diagnosis/repair job.

I first started with the magnet and the reed switch to cycle through the freezers 4 options. With a clamp multimeter I was getting similar amp draws for the first 3 options but then then the 4th option (evaporator fan motor) I got 0 amps as my reading.

Everything at the back of the freezer seems fine. There doesn't seem to be any leaks, the condensor fan spins (when in test mode), the condensor is warm and I can hear it, no obvious damage.

So I decided to check the evaporator fan at the front. In order to access this you need to pry off the cooling tower and unplug the fan. There is also a white lead that is attached to the same wiring harness. I believe this is the thermostat/temp sensor as one end sits up behind the cooling tower and the other attaches to the top of the evaporator. ( I do not know how to check whether this is working)

Using a 9v battery, I checked the fan. It works fine.

I am about to check the defrost heater by using a multimeter on the ohms option. This will tell me whether thats working.

I have read that a good check is to find out whether the defrost thermostat is working by checking its continuity, putting it in a freezer and having it open/close etc. BUT i can't find one anywhere. All the photos I found are of a small round cased object that can often look visually broken with the top broken open. Anyway, this freezer does not have one, that I can locate!! Am I blind?!

The only other thing that I can think might not be working is the potenitometer behind the single knob that turns from cold to coldest.

I am at a loss as to what else to try/check. I'm happy to buy some repair parts but does anyone have any advice as to what my issue is?

Thanks in advance.
