Report "20 amp breaker, said unit starts fine, trips reset thermal switch usually between 30 to 50 lbs. Press reset switch, then it runs up to around 80 to 90 lbs. trips again, reset again and it pressures up to cut off around 125 lb. It has been in the shop at least twice, they said nothing is wrong. Both capacitors test good, pressure switch and unloader valve are good. Motor does get very hot very quick. Been on the shelf for about 4 yrs., disgusted. Help would be very appreciated. Thanks, Tommy, MS"
