Question about Ruud UBHC Air Conditioner
Ruud heat pump clicks when producing heat when the compressor comes on. No click is heard when only the fan is running.
The term H.P. is just a reverse flow a/c. do you have one big machine outside or do you have the h.p. outside with the "airhandler" inside. up in the attic, a closet,garage, etc?
if the sound you hear is coming from the airhandler, then it is the heat strip relay/contactor kicking i and out providing supplimental heat.
if it is the outdoor machine, or h.p. then it can get tricky.a onetime click is probly the contactor sucking in or the reversing va;ve energizing.if it is numerous clicks then it becomes a low voltage control problem.
a loose connection can cause this.check around the contactor, reverse valve solinoid, and control wire nuts.Quite possibly a bad relay.look for the rvr solinoid not being on the 4 way valve properly.
good luck with low volt problems.

Many thermostats have a setting to keep the fan running instead of cycling with the compressor. Check its settings.
