Low Limit Proof of Fire Switch
Used on all Lennox pellet stoves and all Pre-Lennox Whitfield stove models.
This switch controls the stove out of the "STARTUP" mode and into the "RUN" mode. This switch also turns off the stove when the stove is cool after "SHUTDOWN" or if the stove runs out of fuel.
This is not the OEM replacement part that uses the screw and fork type fasteners for the wire leads. This switch requires modifications to change the terminal disconnects at the wire ends from the fork-type to 1/4" female spades.

How Low-Limit Switch, part #XP3004-1, 12057601-AMP (140°F-20 lLow-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.

Read More About Our Shipping InformationWill this thermo disc replace the low heat one in my vogelsang 5770 slimline pellet stove? I can't find a replacement for it. I would also need a gasket for it as well. Any help would be appreciated.
According to the manual for the VG5770, your stove calls for low limit switch, part number 80599.
However there is no gasket between this t-switch and the exhaust blower housing. There is a gasket between the high limit switch seen at this link: 80601. We have both t-switches in stock. Feel free to call us direct with any questions.
