5 year old samsung fridge. Both fridge and freezer are not cooling at all. I’m an EE. I opened it up and the sub-pcb board looks ok. Tested fuse and it is good. Self-diag from the front shows 4 eights with no blinks. However after the unit is on a bit, the led on the sub-pca blinks continuously. It seems from the label that means bad compressor. I hear no clicking though, it’s like it’s not even trying to come on so I’m thinking it is a circuit still and not the compressor itself.
What do I test next? Day before christmas and I can’t get anyone here for days, sigh. Maybe disconnect the compressor start box and test that or the compressor somehow?
thanks
