Heatilator High Limit Switch (SRV24968)

Replacement 320 degree high limit switch / temp sensor for Hearth & Home gas stoves and fireplaces. Used in natural gas (NG) and propane (LP) units. Fits the following models:

Note: This is a normally open switch that closes with heat.  It works by grounding out the valve and shutting off the burner in case of an over-fire situation. This switch has been updated in design.  It no longer features a manual reset as the switch will automatically reset after it cools.  It's also slightly larger than the original.  This will not impact performance, but you may need to remount the new switch.
