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 ?

God bless

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:
Quote:
the unit has a X-13 constant torque motor which is tricky for some Pros and hard for a DIYer to troubleshoot... It uses a low voltage signal from the circuit board to energize the motor. Has no capacitor and is not a PSC motor. You need a flow chart and some electrical experience and test meter and to follow the chart steps to check it, not easy to do over the net.
Here's a pic of wiring diagram for ez viewing:
