HVAC Depot Pro Tip

A furnace temperature switch may open because of an actual overheating condition rather than a defective component.

Before replacing the Carrier HH18HA495, inspect the furnace's operating conditions and determine why the temperature safety circuit activated.

Recommended diagnostic checks:

  1. Verify the complete furnace model and serial number.
  2. Confirm the original switch part number is HH18HA495.
  3. Inspect the surrounding furnace components for overheating.
  4. Check wiring connections for corrosion or damage.
  5. Verify the temperature switch's operating condition using manufacturer-approved procedures.
  6. Investigate airflow restrictions or combustion-related problems where applicable.
  7. Confirm the replacement switch matches the manufacturer's required specifications.

HVAC Depot Pro Tip: Do not substitute a temperature switch based only on physical appearance. Different switches may have different opening temperatures, closing temperatures, and reset characteristics.

Important: Never bypass a furnace temperature safety switch. If the switch repeatedly activates, the underlying equipment condition must be diagnosed before returning the furnace to service.

Installation and testing should be performed by a qualified HVAC technician.

Equipment / Model Compatibility

The Carrier HH18HA495 is intended for select Carrier, Bryant, and Payne heating equipment requiring the SWITCH TEMP (FRS1/2) component.

Exact compatible furnace model numbers have not been independently verified.

Before ordering, confirm the complete equipment model number, serial number, original switch identification, and manufacturer-approved replacement information.

Compatibility Notice: HH18HA495 is not a universal temperature switch. Confirm equipment compatibility before purchasing.
