    Hi all! Happy eary spring...
    So I have been running my M55 for years now in Auto and turning on and off with my Lux T900b t-stat, OR, letting it shut off automatically at a late evening programmed time...
    All of a sudden, I have the situation where I go to the T-stat and manually shut the stove off (stove is in auto) and it "keeps on going as if it was in Manual" except the flame is much lower....
    Haven’t messed with the T-stat, or pulled out the stove or played with the buttons...The only thing I have done is to unplug the stove for a minute and then plugged back in. Any ideas greatly appreciated!
    Thanks, Bill

    Posted on the other Message board as well....

    It sounds like your Mode Selector switch got moved to "Hi-Low" from "Auto off".

    In Hi-Low mode the stove never shuts off (unless there is an error problem or it runs out of fuel).
    In Hi Low Mode......The Thermostat acts like a switch that tells stove to run at what ever high Heat level setting you have selected (1-5) until it reaches desired "Thermostat temperature goal" then to drop down to Level 1 until the Thermostat calls for heat again.
    Rinse/repeat etc.
    This is how I run my M-55 as I don't want to wear out the igniter in Auto Mode
    Good Luck

    No ideas for you...I was gonna suggest maybe the wires got disconnected. but you haven't had the stove pulled out recently. Good Luck and keep us posted.

    Problem solved:salute: Loose wire...comes out the side behind the surround and along the bottom edge of the fireplace before it disappears down a hole to the basement. Must have stretched it a bit :faint:Another lesson learned!
    Happy early spring! Bill

    Good find! Was it the wiring that runs to the stove from the t-stat?
