Is that a XXV/ I had one in a place we sold last year, nice stove.
Love my Harman P-68. Trouble-free.
Tip: Softwood pellets (by the pound) have more btu's (10-20%) in them than hardwood pellets, they produce less ash and will require less maintenance. Fact Fact Fact.
Holy smokes - - - the old XXV is fighting me this year. Won't run, and I've always had good luck fixing it as needed.
At first, controls acted a little funky. Ignitor would get hot and pellets would smoke, but it wouldn't take off. No error "blinks" from circuit board. Was thinking I missed sealing the new door glass, but no error code to indicate same.
Then ignitor went cold after a few attempts.
Changed ignitor, no go. Controls still acted odd, so changed circuit board. Then got a 3 "blink" error, meaning Exhaust Sensing Probe (ESP) not detected. At least I got an error code, so step in the right direction...maybe...
Working on a new ESP now.
The Ignitor, Board, and ESP are all old, and had replacement parts on the shelf.
Now I feel like I'm just throwing parts at it, and it's not a good feeling....
