Question about Ruud UAMB Air Conditioner
My heat pump, in the air conditioning mode, has the internal fan running, but the outside unit does not come on, When checking the circuit board in the outside unit, it shows LED 2 flashing and LED 1 off. What is this LED indication, and does this indicate the problem with the outside unit? Model No. UPNE - 048JAZ
Check to see if there's low voltage reaching the contactor's coil. If there is. and it doesn't close (pull in), then it's defective and should be replaced. Cut the power and check ohms to be certain.
