I sometimes repair domestic refrigerators. The last one had a defective motor start relay. It is a klixon, the compressor motor is a induction start and induction run. No capacitors.
I went to an parts house and the counter help said we recomend to put a start capacitor in place of the relay. He said thats what all the appliance techs do, it's cheaper.
I like to allways go back with OEM parts. I would think the start winding maybe damaged by the start cap. I know the start winding are dropped out by the relay, and the start cap has a relay.
What do the refer techs say? Is it y'all policy to skip the relay and just put in a start cap?
