Magnum 7500 Convec. Fan Running Constantly

[avenged06x]

Hello all. Just getting started with the pellet stove scene. Had a power outage the other day and ran my stove on a generator which I dont know if it has anything to do with the issue I am having now. I ordered a new plenum fan limit switch (200off 140on 90off) as I thought this was my issue and as soon as the stove cools to 90ish the switch will click but fan will run non-stop until about five or so minutes after I shut it down. Am I looking at a snap disc issue possibly? Hope I got all the info you guys need!

Lemme know if you need more.

Appreciate the helpin advance!!

If the switch is a off at 90 and you state that it is 90 ish and still running the stove may still be warm enough to keep the switch happy. Output can be lower than what the stove is depending on several factors. If the fan is coming on and running that's good,its when it quits when the stove is hot that things will warp etc and hopefully the overtemp switch shuts the auger down to prevent any damage.

But when it drops to 90° You can see the switch and also hear it click thus meaning the stove should heat back up to 140 and distribute that hotter heat. My old plenum switch worked before we had a power outage now my convection fan just runs non stop 24/7.

I know on the 3500 the fan circuit is hot and the snap disk controls the fan.

So should I replace the snap disc by the high temp shut off switch? I checked the resistance on it and the only time it opens is when I turn the stove off.

Also I read that the low voltage button had to be broke off for my fan limit switch to work correctly. I did that and now the auger won't turn and the led blinks rapidly.

I would give magnum a call. Hopefully they will still have someone that's versed in its operation. Bill used to be the lead tech.

Emailed them. Didn't get very far. Is this switch wired correctly?
