HVAC people ! Please help ! Technician says external unit grounded, & blew out the fuses.?

Question

He said it must be REPLACED because it was grounded. Is this true, or is this another way to make me pay more? I don't know anything about A/C's, but it doesn't seem reasonable to me that because an appliance has been grounded, that it is destroyed! Couldn't it be repaired?

Answer 1

HVAC Tech.:  Wait 24 hours with unit turned off. Have a technician from another company check it again. This can happen, and often dose. Because of the expense involved in curring it you need a second opinion.A burnout is the worst kind of mess to have to clean-up.I hope that is not your problem. You don't say how old the unit is . It could be covered under warranty. The compressor change out under warranty means you'd only pay for the labor. Good Luck!!

Answer 2

Your compressor is most likely the problem. If you don't trust your tech, then get a second opinion. This is replaceable, but is pricey.

Answer 3

It seems he said the compresser is shorted to ground in which case the compresser could be replaced. If this is what he said, it means the electrical wiring or windings inside the compressor have made contact with the frame of the motor causing a short.  This causes excessive current to flow causing the breaker to trip.
