SUGGESTED FIELD TESTING/ accumulation. This is accomplished by reversing the heat pump to the cooling cycle. At the same time, the outdoor TROUBLESHOOTING fan stops to hasten the temperature rise of the outdoor coil and lessen the time required for defrosting. The indoor Testing Defrost Control blower continues to run and the supplementary heaters are energized. -
Page 11: Testing Defrost Thermostat
Testing Defrost Thermostat 1. Install a thermocouple type temperature test lead on the tube adjacent to the defrost control. Insulate the lead point of contact. 2. Check the temperature at which the control closes its contacts by lowering the temperature of the control. It should close at approximately 30°F. -
