Coal-trol shuts off

I just fired up my leisure line stove (3rd year) and after about an hour the coal-trol shut off and the thermostat is dead. I changed the fuse but that doesn't help. I have no light on the back of the control unit and nothing on the thermostat display. I've checked all the connections. Any suggestions???

Have you checked the breaker for the outlet that the coal-trol is plugged into??? No red light= no power in...

Yes, I've checked the breaker. The power vent is on the same outlet and is still running.

Was the fuse that you first removed blown?

It looked fine, but I changed it just in case.

If the fuses are not coming out blown then it sounds like a fault in the control box... Try plugging in each motor (feeder, combustion blower, distribution blowers) directly to outlet power and see if they all run freely... Possibly a 'tight' motor could be putting a strain on the unit and overloading it?? But, that is what the fuse is there for, to break the connection in the event that the load asks too much... Hmm, not sure here, but try that just to be sure all motors are free and working properly... If you have an adjustable carpet on your machine you can just plug directly into the outlet along with the combustion blower and distribution blower and manually throttle the stove if needed, but again, you would need to have the adjustable carpet option installed to do this...

Hey, wait a minute, you have a WMO-1 fume switch on your unit that the coal-trol plugs into right??? If so (and you really really should have one) that is most likely your problem... Let me know and I'll tell you how to reset it...

The WMO-1 looks like this and should be mounted through the back wall of your stove-

I do have the high temp switch.

I think that is the problem. I just bypassed the plug from the high temp switch and it is back up an running. I don't think the temp was too high. I actually thought it was not putting out as much heat as it should be. How do I reset?

Ok, just to confirm that it is the problem, unplug the coal-trol from the cord coming from the WMO-1 and instead plug the coal-trol directly into outlet power... If the red light on the control box comes on and all motors start to work again then the WMO-1 has tripped and will need to be reset... Do that and let us know what you have... Just remember that there is a reason that the WMO-1 fume switch tripped in the first place and it is there for your safety to do exactly that, so there is an issue somewhere that MUST be addressed that is the cause for the fume switch to trip in the first place, such as a lack of draft or a blockage in the chimney or stove pipe somewhere or the barometric damper is not properly adjusted, so just because you may be able to plug the coal-trol directly into a wall outlet and everything seems to operate fine does NOT mean that the stove is SAFE to operate that way... Understand???

I have just cleaned all the pipes and the power vent fan this week. possibly the damper was sticking shut. If I remember correctly, the sensor is for high temps, not fumes. The draft not working correctly would also cause high heat, but like I said, the stove was not that hot.

It is not an over-temp switch, instead it is a temperature controlled switch... In the event that your stove looses draft the hot gasses inside your firebox have nowhere to go, no way to exit the stove, so what happens is the gasses travel through that tube that goes into the body of your stove and the high temperature of those gasses contact and heat up the switch that is mounted to the back side of that square silver box, when the switch reaches approx. 200 degrees it 'breaks' just likes a circuit breaker... So you see, it is not an over temp switch, just a temperature controlled switch...

First unplug the WMO-1 from the outlet that it is in, then, see the small hole in the center of the face of the square box??? Use a 3/32" or smaller allen wrench or similar, insert it straight into the hole and press straight in, that will reset the switch... Or use either a straight blade screwdriver or a 1/4" socket and just loosen (don't need to remove) the 2 sheet metal screws one on either side of the square box then just slide the face cover towards you and remove it... Under the cover you will see this red 'button' type thing, (at the tip of my screwdriver) that is what you would be pressing on if you used the allen wrench through the hole in the cover, but now you can press it by hand...

Got it reset. Thanks. I will re-light and stay up with it for a while and report back before going to bed. Thanks again.

Thats all good having cleaned everything...

Is it very windy where you are??? Maybe the power vent took on a direct headwind and couldn't properly vent the stove??? Have you properly adjusted your barometric damper at full fire??? What speed are you running the power vent at via the rheostat control??? Full speed, half, quarter??? If the condition persists I would first get a manometer if you don't already have one and set your barometric properly, or at very least just ramp up the speed of the power vent so it pulls a slightly stronger draft on the stove...

After testing it the first year, I found that I could run the stove fine on the lowest vent fan setting, but I will keep it up at about half for now and slowly ramp it down again to see what happens. My thinking is that the less heat you pull out the better in fuel economy.

Right-O, good deal my friend!!!

I agree with your thinking about pulling heat from the stove, very true, very true...

Let us know if it gives any more trouble and keep warm!!!
