Refer to the heating data on applicable models for
the preselected temperature the compressor shuts
off and the electric element is energized.

POSSIBLE CAUSE

PROBLEM

Compressor shuts off on

outdoor thermostat but

element does not heat.

TO CORRECT

Check fuse link for continuity. If defective, replace.
Check amperage draw of element. If no amperage,
replace.
Check voltage to element. If voltage is okay, check
wiring.
Defective coil. Test coil for continuity.

Fuse link.

Heating element shorted.

Incorrect wiring.

Heat relay or heater contactor coil open.
