$42.00

  • Model: PP3001-PSP
  • Shipping Weight: 1lbs
  • Manufactured by: Whitfield


Low Limit Switch F140 Ceramic Disc for Whitfield Pellet Stoves and Many Others.

Whitfield part #12057601  
Also known as F140-20
This switch is not limited to Whitfield pellet stoves and also is used on Enviro pellet stoves and others.

An OPEN failure is indicated by the inability of the stove to run longer than 30 min. It is too common for control panels to be replaced when it is only this sensor that has failed!
The Low Limit Switch's function is to monitor the temperature of exhaust gases and is designed to shut down the stove if it does not sense the heat of the fire. Power loss to the Fuel Feed System will only stop the Auger Motor and pellet feed. The stoves Combustion and Room Air Blowers will still receive power until an exhaust temperature reading below 110 degrees F.

The Low Limit Switch can fail either in the OPEN or CLOSED position. Both failures have distinctive indications of failure. It's a surface mounted switch located on the throat of the Combustion Blower housing.
This normally OPEN switch is rated to close at 140 degrees F.
It resets to OPEN when temperatures drop below 110 degrees F.
An OPEN failure is indicated by the inability of the stove to run longer than 30 min. The control board timer completes its cycle but the Low Limit switch fails to close when hot gases go undetected through the Combustion Blower housing exhaust. The stove restarts with the push of the START touch pad but shuts down again after 30 min.
A CLOSED failure is indicated by the continuous fan operation after the stove’s fire has gone out and the stove is cool. By removing the power cord from the wall all fans stop but immediately start when the stove is plugged back in.

Both failures require the replacement of the switch.
