Order now and save on the Mars 39039 160 Limit Switch MR160 Manual Reset 3/4" at PlumbersStock online. 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 replacement parts can be hard to find, so contact us if you have any problems.
