Get a great deal on the Mars 39019 150 Limit Switch L150-40 Auto Reset 3/4" here at our online store, PlumbersStock.com. 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. It will remain off until the switch automatically closes the circuit when the temperature reaches the off threshold. Mars replacement parts can be hard to find, so contact us if you have any problems.
