My blower will not shut off. The burner seems to cycle on when needed but the fan keeps running after the burner shuts off. What should I be checking . ( Nordyne model MIMA056AW )

Hi,
With t-stat set to heat-auto and temp met and blower does not shut off, test across control board W and C for 24VAC .
Then test across the Heat terminal wire(orange) and the 2nd Neutral terminal from the left (4 neutrals-2nd from left) for 120VAC.
IF you do not have 24vac at W and C, BUT do have 120vac at Heat and Neutral, the board is bad.
Integrated Control Board # 903429 can be seen and ordered from this page:
