Our airconditioner circuit breaker went out on our heat pump and we replaced it and now it works but our blower want go off
The blower relay (called a fan relay) is stuck and must be replaced.
Want to do it your self? Trace the two power leads from the blower motor. usually white and black for high speed, White and red medium.
(Blue,purple and brown are capacitor colors)the white wire goes to the line side of the contactor. the black or red wire goes to the fan relay. This arrangement allows the blower to continue running for a minute after shut down to dry the cooling coils or complete the heating cycle. (Line side is where the incoming power wires connect)

Check your wiring between the contactor and compressor for a short to ground, or check the compressor windings for short to ground.
With the Tstat off, the contactor should be open so the only way for the compressor to be trying to do anything is if the 110 volts from the unbroken side are traveling through the compressor to ground. Since 110v is not enough to run it, the overload is kicking it out, cooling off, and repeating the cycle. When you kick on the Tstat, the contactor is supplying voltage directly to ground without going through the resistence of the compressor windings and kicking the breaker.
Post back and let me know what you find.

Hello my name is Heath it will be my pleasure to assist you. First thing to do is go to the furnace take off the lower blower door and locate the circuit board turn the power off to the furnace. In the circuit board there should ba a small car like fuse usually 3 or 5 amps check the fuse it is probably blown replace the fuse with the same amperage fuse and then turn the power back on on the furnace and check the operation of the furnace.
