I have a 60 gallon, 3.2 HP upright Craftsman Professional Compressor. It seems to be having a problem kicking on when it hits the low pressure setting of 90 PSI. It tries to start but then pops the onboard breaker. I can see the pulley trying to turn over when it does this. I thought the belt might be too tight so I backed off the tightness a wee bit.
It seems that when the tank is completely empty it starts okay, though sometimes I have had to give the pulley a little help with my hand. But it just won't start when it tries to kick on at 90 PSI.
Oil is good. Filter is new. Belt is not too tight. 240V on twin 40 amp breakers.
Could the low pressure side be set too high? Any guidance will be greatly appreciated.
