Fan runs, compressor will not start unless I jumper across R-Y Comp switch. Then unit runs fine until thermo shuts comp off. Comp will not restart when thermo lowered. Thermistor ohm’s ok. Cap checked out ok, compressor sounds fine when I jump start it. The fuse for the R-Y Comp switch is ok. This unit has two circuit boards, about $40 each. I could justify replacing one of them but not both. Any best guesses on which board the problem lies? Thanks
