    I didn't realize we were talking about an electric heater with A/C.
    That 60 amp breaker is not for the A/C.
    Turn on power to the air handler and see if it is flashing diagnostics codes.

    One thing I noticed about the photo of the circuit breaker , the lugs where the 2 large black wires terminate , show corrosion .

    With the circuit breaker in your panel turned on . Be CAREFUL !

    If you have a volt meter & wearing leather or rubber gloves , test to see if you have 240 VAC at the 2 black wires / lugs

    If good , test at the 2 lugs at the opposite end of the circuit breaker . Where the small black & small red wires are located .

    God bless

    Does this unit have a switch on the door and has it been checked?

    I do not see a switch on the door, as you describe.
    FWIW, the wiring diagram is available here in PDF.

    Thanks!
    Hoping someone more knowledgeable than I might be able to look further at the wiring diagram to see if there are provisions for a panel or door safety switch.

    Did not see a door switch in the wiring diagram .

    Can not remember the correct name , but the diagram looks like this may be a variable speed motor ?

    Great, thanks!

    If no door switch, we're back to:
    Power on to air handler...
    No flashing codes or lights.

    FWIW, as for the motor, others have told me the following:
    Here's a pic of wiring diagram for ez viewing:

    My connectors appear to be individual wires plugged into a non-removable panel on the motor, rather than the high voltage plug and low voltage plug, which he disconnects, beginning @4:54.

    So the connections should be labeled for you to figure out which to pull out and check

    I would think the white block the wires are plugged into, they maybe just raised letters and hard to see.

    Or perhaps on that diagram

    this will help understand some of the wiring but right at the end he talks about a flood switch that turns everything off if the water isn't draining

    I need to watch that several more times but I DO have a flood safety switch like that:

    That would be easy to bypass to prove it isn't a problem.

    Neal, where are we with this one?

    What's not working and what has been tested?:confused:

    Givin the location of the motor and individual plugs on it it will be hard to test for power there. So before he gets into that I just want to make sure it isn't some other switch like the float or something. But as usual, I am over my head.
    We will need a better picture of the wiring diagram and maybe by feel he can find the other ends of the wires to test them.:hide:
