So I have a Parlor 3000 that was manufactured in 1994. I light the stove and set it to low and it feeds pellets but after some time it shuts down. If I adjust the feed rate to medium or high there is no change in feed rate or fan speed. I have replaced the t-2 sensor. The one attached to the metal plate which I assume measures temp. I'd like to replace the t-1, but I'm curious what it does. I've taken it out and inspected and cleaned out the hold where it mounts. But there is no change. So my main question is what does the t-1 do and would it resolve my problem?
