    Hello All,

    After getting some good advice via lurking on this site and asking some questions before, I am back, hat in hand, again.

    Within the past week I had noticed that the Integra, after several hours of flawless operation (overnight) was letting itself almost burn out by stopping the auger motor (combustion and convection motors both kept going) only to start right back up for a while. This caused it to be producing only 'warm' air, instead of hot air. I would clean out the burn pot and ash pan, checked the limit disk in the exhaust chamber, cleaned that off and fired it back up, for several more hours of hot burning, only for the cycle to repeated the next day.

    Finally, today I had enough, I took off the two back panels of the stove, cleaned the air intake sensor (it was a little dusty), cleaned the inspection area behind the heat exchange tubes and brushed out and blew out the vent pipe (both inside and outside the house).

    After that, I fired up the stove using my usual routine (turn on for a 3 count, shut off, toss in a handful of pellets, ignite with blowtorch, wait til that gets going good and then turn stove back on). I left the left side of the stoves' panels open, so I could watch the combustion and convection fans (not sure why, bored I guess). After the normal start up routine, which appear to be going normally, the auger motor, convection motor and combustion motor all stopped at the same time. I looked at the other side of the stove, and the auger feed indicator light was blinking rapidly. I flipped the switch to the off position, and the combustion and convection motors kicked back on, and the auger motor stayed off. Eventually all motors stopped and the stove is now cooled down.

    My question is, does this seem indicative of a limit switch issue, a control board issue or something else? I have a local guy who I trust to diagnose this issue since he used to sell these stoves, and now has a business specifically for servicing this brand, among others, but I would like to fix it myself if its easy enough. I am not very handy when it comes to electronics, but I do have a craftsman automotive voltmeter.

    It seems to be just my luck this happens right when we are getting to the cold weather (projected to get down to -10 here up in the hilltops of the Mohawk Valley in central New York). Until now, this heating season had been fantastic (burning Somersets for the first time, holy cow, the heat they produce!). Currently running the backup propane furnace, watching my wallet grow thinner.

    Any help would be greatly appreciated.

    Thanks,
    Ryan

    Mine was doing that last year, I put a jumper wire on the low limit switch and worked fine, so I replaced the low limit switch, there is a better switch out there now and cheap. do not stay running with the jumper wire on the low limit switch....but it will keep you warm till you can change it. hope you have someone close to buy parts from.

    Well, I got a jumper wire ready, and started up the stove, patiently waiting for the stove to shut itself down again.

    It didn't happen. The stove kept running as though nothing was amiss at all.

    Ideas?

    Also, out of curiosity, what, if any, surge protection or battery backup do you have fore your pellet stoves, and what would you recommend I get for mine?

    It still might be your low limit switch, that's how mine was going, then I changed it worked for a few weeks then ended up changing my high limit switch. and for the surge protection, be sure to get a good one...;) the one he posted looks good.

    Well the stove did the same thing again. Thankfully this time I had a jumper wire, popped it on the low limit switch and low and behold it ran like a champ. Looks like a limit switch is in my future. Thanks for the help!

    I contacted the local pellet stove servicing company, and they happened to have a low limit switch in stock for only 15 bucks. I popped it in and we are off and running again. Thanks for the help!
