  1. Ken MacDonald says:

    Rheem 4 ton heat pump-in cooling mode did not go back on. I was told by the service man that came out that it was the transformer. He offered to replace it for $340.00. I found the exact same transformer online for $28 including shipping so have ordered it. I can replace the transformer myself. The rest of the circuit is live-went through it with a multi meter. It seem that the problem is electrical as there was no mechanical indication of failure: sounds, grinding, etc. The compressor is new, fan outside is new, fan inside turns like butter, had a surge protector installed four years ago.

    What else could the problem be? I have new thermostat installed and will find out when the transformer comes.
