Potter & Brumfield is a really major relay maker. I would start by going to
their web site, determining whether this is a current production product,
and checking who sells it in small quantities.

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
