Hi Guys, the flame kept going out, so I took off the side panels and saw that the convection fan wasn't on. I ordered a new one and installed it, it worked for a few minutes and then stopped. I hooked new convection fan up to its own electricity and it is fully functional. Should I replace the control panel next or the circuit connections to the fan?

I would test and see what voltage is at the 2 wires that go to the motor first. If it is not 85vac or more I would suspect a bad control board.

Would you explain further
Does the stove start pellets drop fire starts
and after a short time, the fire goes out and the fan stops?
OR
you start the fan comes on and after a few seconds, the fan stops?

 

[saigon71]

The stove starts, drops pellets, the flame slowly goes out bc fan doesn't come on.

 

[johneh]

The fan does not come on when you hit the start button Correct?

 

[saigon71]

Yes

 

[johneh]

In order for it to drop pellets and the ignitor to fire them, the Combustion FAN HAS TO BE ON

Ok, this is very helpful, I will try this. I wired the fan separately, but the stove just shuts off, the white wire goes off to something else.

I can send you a video if you want. My ignitor hasn't worked in awhile, but it drops pellets and flame goes out, convection fan is not on, exhaust fan is.

On the fan, the purple wire is power
The white wire is ground(common)
Is there at least 85 volts at the purple wire
( as Ssyko asked)
Here is the Teck. manual for your stove

You have a couple separate issues going on. What light is flashing on the control panel? How long is the flame on before it goes out?

I assumed you have cleaned the unit including pulling off the exhaust motor. I do not know how old this unit is, but I pull my motor every 5 tons and I can tell the difference after it has been cleaned. Your convection fan will not come on until it hits a certain temperature. I would start by pulling the wires on the vacuum relay and close them with a male to male spade connector. If it operates then it could be the vacuum relay or you have leakage somewhere else that is causing the relay not to close. You said the ignitor is not working so I assume you are hand lighting it. How long before pellets stop dropping and the unit goes into shutdown mode?

Just want you to understand there are two fans, a combustion fan and the room air convection fan. Convection fan has nothing to do with creating a fire in the burn pot. Combustion fan comes on immediately when pellets start dropping.
