Can Progressive EMS cause capacitor failure?
One of our Coleman ACs is acting up since connecting to a faulty electric supply. The Progressive energy monitor started routinely shutting down on low voltage, so we talked to the host about it and got another site. She told me they just had an electrician out and would call him again. Then, when disconnecting, I noticed a 40 amp breaker for the 30 amp plug. I didn't worry because of the Progressive EM.
Immediately thereafter our rear AC would trip when changing the fan speed from low to high. No breaker trip, just the normal cycling time before restarting. The fan turns freely and smoothly. Otherwise the unit works great and has been - at high fan. I am not an electrical engineer, but I suspect the run capacitor and will get on the roof to check it later. If it is a capacitor I will change all of them.
Perhaps it is just a coincidence. Or maybe, because of the EM, the repeated power shutdowns (and starts) may be responsible. Still glad to have the Progressive unit because it might have prevented worse problems.
