this has got me thinking. what else has somebody changed in the stove that you dont know is right or not. with a low pellet feed did the auger get changed and a 1rpm get installed instead of a 4rpm? is the mainboard the correct one? have the limit switches be changed?.. heres some homework for ya bud, pull the auger out and put 110v to the leads and see if it's 4rpm. ck the numbers on your limit switches high limit should be a F250 Thermodisc- 60T11. low limit should be F110 Thermodisc- 60T12.
