Enviro EF3 won’t stay on

Enviro EF-3 not staying on

Hi everyone. I have an Enviro EF-3 that’s about 10yrs old. I cleaned it and it lights right up but shuts off after about 10min. I had this problem 2yrs ago and cleaned the ceramic low limit sensor with some alcohol and it burned great for the whole winter. Last winter I tried cleaning it again and it still keeps shutting off after 10min. I figured the sensor probably chit the bed. Before buying a new one, I tried bypassing the sensor with a jumper wire and it still shuts off in 10min. Hoping to get it fixed up for the coming winter. Any ideas?

Fotherbyc welcome to the forum. First, a little more info will be necessary
When you start the stove do you just allow the auger to supply pellets or add a handful to start?
When the stove starts does the Green auger timmer light flash every time the auger activates and drops pellets?
Have you had the inside of the firebox apart? steel brick panel, and 3 panels behind. Cleaned the passage
from the firebox to the combustion blower and beyond? Once we know the answers we can dig a little deeper

Hi Johneh,
Thank you for the welcome and for the reply.
Typically I had a small handful to start and yes the green light does come on every time the auger activates. I am by no means a repair man but typically pretty handy and since I’ve had the stove in the fall I completely strip the fire box and clean out as best I can including the 3 panels and behind the insulation. I also remove the side of the exhaust blower and vacuum that out. Typically 3 times a winter I will also shut it down and do a good clean of the box. Last season when this issue started I had just done a full clean to begin the season. Fortunately I had just had a heat pump installed and made due with it and a space heater on really cold days but would love to have the stove working. My son and I are going to take another look at it this weekend, hence the post looking for suggestions. If I can’t get it figured out I will try to get a video or some pics too.
