Parts Used
Swapped the pressure switch and it does the same thing. Going to try the start and run capacitors.
Don't know which one is bad yet. Have to do some digging to see how to test and where to get replacements because eReplacements does not have them. There are two capacitors on top of the motor. So, repair not complete...yet.
