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.
Nothing in this diagram, it's very basic. Are there any others on the unit?

BE CAREFUL!!
Turn power on to unit.
Put your volt meter leads on L1 & L2 on the TBI in your diagram.
240Volts?
Now put your leads on the orange and black wires leading to the CT control transformer.
Still 240Volts?
Now put your leads on the brown and read wires on the CT.
24Volts?
