Description
The Amana-Goodman 10123535SP Manual Reset Limit Switch is a safety cutoff part that interrupts furnace operation when internal temperature reaches 150F, preventing overheating conditions. It operates through a heat-sensitive bimetal element that opens the electrical circuit at the rated threshold and remains locked out until after inspection. It is mounted inside the heat section where airflow and combustion temperature are monitored, restoring safe operating conditions after a trip and reducing thermal stress on internal furnace components during abnormal temperature rises in HVAC systems such as gas furnaces.
