This premium disc limit switch is an essential safety component designed for residential heating systems and HVAC equipment. Functioning as a high-limit control, this switch monitors the internal temperature of your furnace or air handler. If temperatures exceed the safe threshold, the switch automatically opens the electrical circuit to prevent overheating and potential equipment damage. Once the system cools to a safe operating range, the auto-reset feature restores connectivity, ensuring your heating system returns to normal operation without manual intervention. This reliable fan disc switch is a common replacement part for resolving issues such as blowers that run constantly or burners that shut off prematurely due to heat spikes.
