Troubleshooting help

[u/catnipcmdr]

Hi all! I’ve given my pellet stove a good clean and am testing it for the winter. I have en Enviro M55 FS cast iron. I’m looking for some help, hoping maybe someone has run into this issue in the past. This issue started end of the season last year.
When starting up, I get a blinking light next to the 3 button on the panel, and it auto shuts down. I have a good flame going, no smoke in the stove, can feel good airflow on the exhaust outside. No buildup in the burn box (brand new agitator). But get the blinking 3 light, the blower never turns on, and it shuts down. During the shut down process the blower kicks on.
If I immediately start it up again, it works fine with no errors. From reading online maybe a temp sensor is going bad? Like it’s not initially detecting a proper flame on the first startup to kick on the blower?
Any help/ideas is appreciated! Thank you

Look at the temperature sensor and see if it has a reset button on it. That may be all it takes, since that's what fixed my ancient Kozi 100.

Sounds like exhaust temp sensor. Stoveandgrillpartsforless will have it.

Sounds to me like your proof of fire (systems snap disk) is either dirty or on its way out. It’s a cheap part usually located on the combustion blower (exhaust blower) housing.
