Hi group --- I need a couple of relays for the control board in an air
conditioner. The unit is a Carrier and the coils on both relays are
open. These relays are on two different boards and were replaced at two
different times about a year apart. The number on the relay is
Potter&Brumfield T9AV5D22-24 It has a 240volt coil. TIA John

Burnt out coils are pretty unusual. But two at once?

Lightning strike?
