Application
This limit switch is a direct OEM replacement part for select Carrier furnaces and heating systems. It is recommended to verify compatibility with your specific Carrier model number prior to installation. Always follow manufacturer guidelines and local codes when servicing or replacing limit switches.
Why Limit Switches Matter
Limit switches are essential safety devices in forced-air heating systems. If airflow is restricted — due to a dirty filter, blocked vents, or a failed blower motor — the heat exchanger can overheat. The limit switch detects this condition and shuts off the burner to prevent equipment damage, heat exchanger cracking, and potential safety hazards. Replacing a faulty limit switch promptly restores proper system protection and ensures safe, efficient operation.
