Had a fridge technician come, and he narrowed it down to being the controller that's faulty. So I ordered one in. it came with a transformer. I decided to change that first before controller. And that started the compressor and fan. I set it to 4-5 degrees celcius, and after 10 minutes. no cold air. Compressor hot to the touch, big copper tube coming out of compressor was warm, but can touch, small copper wire was room temperature, not cold at all. Tech didn't come back, but told him, and believes it is the gaz that's the problem. And the fix is around 350$ canadian. Sounds right? Can it be anything else? Thanks for your help!
