    OK I had a guy come over and check out the unit. We found capacitors not meeting spec and the unit when running is pulling 19 amps. He did replace the Run Capacitor and brought the system down to 12 amps.

    He said to replace the defrost sensor and defrost control system which is set to 45 degree I noticed. Even the blower capacitor is not meeting spec, I replaced that not even 2 years ago. But he did show me the read out and the computer doesn't lie. I guess I need to use GE or some good brands and not china stuff.

    Also the fan blades are to far from the coil, the blades are not even flush with the shroud.

    So this is where Im at and the freon is just fine right at 40, a little over he said.

    Yep the China crapacitors are junk but there are a lot of them sold. The fan blade location will sure make a difference in air movement and it should be located correctly. Glad you got it running.

    PS best capacitors come from Amrad engineering

    They also make the Turbo capacitors but there regular capacitors for HVAC work cannot be beat. They are not real cheap but they last just about forever. We have been using them at the university when we do our testing to provide a base line to compare to the china junk.

    I replaced the P291-2004 run capacitor but need to get the one that is daisy chained to it also. It is a little bigger. Anyone know the model #?

    I will climb back up and look.

    Thanks
