I have a competition 1250 I’m having a hard time with it ever reaching the set point temp. Tonight 50’s out set at 350 only get up to around 280-290 and stay there. I this thing end of last summer and started acting this way last fall figured maybe cool weather but 70 degree to 80 degree days it struggles too. Cleaned the temp probe have tried about every type of pellet imaginable just looking what I could be doing wrong.
