Heating Element Resistance Check (at Contactor)

1. DISCONNECT POWER AT CIRCUIT BREAKER.
2. Remove control panel.
3. DO NOT REMOVE HEATING ELEMENT LEAD WIRES FOR THIS TEST.
4. Place test leads between terminals A and C on left side of contactor.
5. Check the resistance and compare to the allowable range in the following table:
Voltage
A-B or B-C
208 10 to 12
220 12 to 13
240 14 to 16
480 55 to 64
6. For three-phase units, check resistance between terminals A and B and between terminals B and
C similarly.
