Had EnergySavers come to house to check the pellet stove issue.
The service tech was VERY knowledgeable, I believe his name was Keith.
After about 15 min of trouble-shooting, he determined by Control Board is the issue, and unfortunately, I have to agree with him.
Ordered part from EarthSense stove part company and it should arrive by Monday. These folks are top notch and you can actually talk 1:1 with their service technicians. They seem to know their stuff !
