I have a Harman P68... worked well the last few years, had a professional clean an install a new igniter ( bought used, never worked) stove shop that installed it is out of business after ripping a lot of ppl off ( pre paid pellets got me for a ton & 1/2) but it’s getting cold an after using the stove 3 times to get the chill out of the house I’m ready to run it daily... I had it set to auto since now with the igniter I can ran twice, after auto shut down ( got hotter outside, so heat stayed inside where no need for stove to run) it tried to fire back up around 11:30pm an all that happened was all lights came in, NO auger sounds, NO sounds for pot blower that helps keep ignited.. an if I turn the feed back below zero to push threw pellets I get nothing but a distribution fan... it’s just making a horrible loud humming... what can I do??? I’ve cleaned it, checked all piping for clogs ( squirrels this summer) filled the pellets area, tried resetting board by unplugging.... what else can I try, not much $ to buy every part an replace an it’s $75 just to have someone “ look” at it to tell me... HELP...
