Ensure the safety and efficiency of your heating system with this premium auto-reset high limit switch. Designed as a critical safety component for residential and commercial furnaces, this SPST (Single Pole Single Throw) fan disc switch monitors internal temperatures to prevent overheating. If the system reaches an unsafe temperature of 210°F, the switch automatically opens the electrical circuit to shut down the heat source, preventing potential damage or fire hazards. Once the temperature drops to a safe 170°F, the control resets itself to restore normal operation. This reliable thermal cutout is an essential replacement part for HVAC maintenance, helping to protect against issues caused by restricted airflow, dirty filters, or blower motor failure.
