About the Limit Switch

The limit switch monitors the heat surrounding the heating elements or other heat sources. To determine if the limit switch is defective, use a multimeter to test it for continuity. If the switch does not have continuity and the reset button has not tripped, the limit switch should be replaced. Be aware that poor airflow through the heater will often result in a tripped limit switch. Make sure that the furnace or air handler is in a properly ventilated location, the air filter is clean, and the air vents are clear of obstructions.
