i have controller power alarm. and i found damaged fuse for 110 and after changed start compressor for 1 minute then stopped and the fuse damage a gine and i get the same alarm controller power.
Sounds like the controller board is drawing too much power – the most probable reason is a short somewhere.
Please check all electrical cables, sensors/pressure switch and loading solenoid – those are the most likely locations of a short.
If you can’t find it this way – try to figure out if the fuse blows at a specific time, for example when the compressor unloads. If that is the case, the problem is probably with the cabling to the loading solenoid, or the solenoid itself.
