Before Ordering

HVAC parts can vary by equipment series, production date, serial number, revision, dimensions, connectors, and electrical or mechanical specifications. Confirm the complete equipment model and serial number, the original part number, supersession history, and all relevant installation requirements. Installation and diagnosis should be performed by a qualified HVAC service professional.
