Install Instructions For Lennox Pellet Stove Proof of Fire Switch: H5887

Instructions for Installing Low-Limit Switch part # H5887, 12057601, (140°F-20 low-limit switch):


Lennox: Elite Montage/ IHP IronStrike 32FS


Whitfield: Advantage, Cascade, Legend, Quest, Renaissance or Prodigy II:


  • To replace this switch, locate the side of the stove where the combustion blower is mounted. The switch is located on the exhaust blower housing.
  • Make sure that your stove is unplugged.
  • Using a flat head screw driver, loosen the two contact points for the wires and remove the two fork connectors. using a 1/4" socket wrench, remove the two hex screws that hold the switch to the housing.
  • If your new switch does not have screws for connecting the wires, use the screws from the old switch.
  • Install the new switch to the housing. Reconnect your wires. It does not matter which wire goes on which terminal.


Note: Not all Whitfield pellet stoves used a low-limit switch for detecting proof of fire: Profile 20, Profile 30, and Optima units made by Lennox used a "photo-eye", part # 14750404

Troubleshooting

How Low-Limit Switch, part #12057601, H5887 (140°F-20 low-limit switch) operates:


Switch should be a normally open circuit that closes at 140°F, opens again at fall in temp 140°F-20°F or 120°F. This switch is mounted in the air path of the exhaust and is commonly not malfunctioning but just dirty on the face of the switch. If your wire contacts wiggle a little on the switch, this may actually be okay and is common. A bad switch can be determined by heating the switch face directly with the flame of a match or lighter. After a moment you will hear the switch click. After you hear the click test the switch across the terminals for continuity. If there is no circuit present and you have determined that the switch face is over 140°F, replace the switch. Also, if the switch face is <140°F but still has a circuit, also replace the switch.

  • does this "proof of fire" sensor allow the blower fan to come on when temp is appropriate? my blower fan wont come one and im trying to diagnose what may be failing. the igniter glows red so i know its hot but the fan stop turning on a few days ago and the pot wont ignite....

    I'm not 100% sure what type of stove you have. If you have a Whitfield, the room blower should come on when the power button is depressed. If your room blower is not turning on, you are going to want to remove it from the stove and apply direct 120-volt power to the blower. If it works, the controller is malfunctioning. This is only if you have a Whitfield, there are many models and some act differently. In general, the low limit on Whitfield stoves detects heat in the stove and only tells the controller not turn off. The stove will shut down after 15 minutes if the low limit switch doesn't close.
