ok that proves the compressor

measure the voltage across the blue capacitor

also measure resistance on green resistor looks like 39 ohm

Dave[/QUOTE
yes the resistance on the green resistor is around 39 ohm.
Now the fridge freezer seems to work fine after PCB replaced, not exactly same model though

If I short the triac transistor(btb16-800cw, the black one on silver metal, photo attached) the compressor and the fan start to work.

yes about right

lists it as 15k should be 15 degrees and at 20k it should be 10 degrees

if it was me I would swop the big blue capacitor and see what happens

Dave

Thanks Dave,
no voltage to the blue capacitor when plugged sound issue with pcb or electricity cut off somewhere

how do you know ?

I tested the resistance and auumes it is fine. The resistance is around 15K ohms at room temperature and around 20K ohms at minus10 degree.

Could it be that there isn’t enough refrigerant or there’s a leak causing the compressor to overheat, making the PTC cut off the power? Are both the thin and thick tubes hot?
