Disconnect the power cord before repairing electrical components; even with the controller off, one phase remains live. Use insulated tools and never work alone on high voltage circuits.
The manual includes a section on initiating a manual defrost via the controller operating menu.
The control circuit voltage is 29 Vac at 60 Hz.
Serial numbers are on the component nameplates: electric motor nameplate on motor housing, compressor nameplate on front of compressor, unit nameplate on unit frame in power cord storage compartment, and MP-4000 controller nameplate on top of controller.
