Limit switches are sensors that detect when a furnace has exceeded operational temperature limits and shut the appliance down as a safety measure. The way it works is that if your temperature gets to a concerning level, the limit switch will automatically open the circuit so it shuts off. The circuit will remain open/off until it is manually reset. Mars makes products that we're proud to carry. Make sure you have the right part number, and if you aren't certain, try contacting us.
