Cross-Reference & Related Parts

Compatibility

Designed for furnaces, air handlers, and packaged HVAC units from Nordyne, Coleman, Concord, and private-label brands equipped with electric heat strips. Prior to ordering, always verify:

• Required coil voltage (24 VAC)

• Heater strip amperage draw does not exceed 30 A

• Mounting footprint and terminal layout match existing relay

Technician Notes

1. De-energize all power sources and shut off gas/heat supply.

2. Document or photograph existing relay wiring and mounting orientation.

3. Remove the old relay and inspect the heater strip terminals for corrosion.

4. Mount the new relay using supplied hardware; ensure insulation clearance.

5. Connect 24 VAC control wires to the coil terminals and heater leads to the contact spades.

6. Restore power, call for heat, and verify the relay clicks and energizes the strips without overheating.

7. If the relay fails to actuate, measure coil voltage at the relay; it should read 24 VAC during a heat call.
