i have a p24i that you have helped me with before/ i think i am having a control board problem.unfortunatly i did not have it on a circut protector.i noticed the fan does not appear to increase in speed the way it did before.when i leave it on 2 the fan is very slow and it overheats and shuts off.if i run on high fan it runs fine.i have recently replaced the blower fan and a weak and noisy auger motor.the stove is very clean. my serial number is 55022 .i have looked online and they want to know the year.thanks in advance for your help i bought the stove used three years ago
