Enviro Meridian augur stops after 15 minutes

[Bveezy01]

Hello, I'm wondering if someone can point me in the right direction here. My pellet stove will start and ignite, but after about 15 minutes the augur will turn more frequently for about 1 minute and then stop completely and then the convection blower will turn on until the fire is out.

I've tried connecting the leads that go to the proof of fire switch and vacuum switch and also replaced the convection blower. I've been trying to use troubleshooting guides on the internet but nothing is helping me diagnose the problem.

When you jump the low limit switch does the convection fan come on?

Yes, it comes on and will not turn off until it is unplugged.

Sounds like proof of fire disc needs cleaning .
What year is your stove ?
Does the control panel flash when it goes out (code 2,3 or 4) ?
Here is the manual for Enviro

Code 3 flashes when it goes out. If I jump the proof of fire will it still cut off the augur in 15 minutes if that's the problem?

See page 53 of the manual
for code #3

My guess would be that you are in thermostat mode with the thermostat turned way down, or no thermostat attached. The startup cycle takes 15 minutes, then the stove is sensing that there is no call for heat, so it shuts off.

Of course, if you are actually running in manual mode, then I have no idea, lol!

If it’s in manual mode jump the low limit and vacuum switches at the same time. If it still does it I’d be looking at the control panel.
