I am looking for a manual or diagram / labeled picture, so I can speak knowledgeably about the problems I am having, here on the forum.
Model DGAA090BDTA

(I am having alternate switch stuck open or closed.
Turning power off and on wil reset it and it will run again... For a while.
Sometimes for 1 or 2 cycles... Sometimes for a day or 2.
I have replaced lower blower last year, and combustion switch yesterday.
Problem persists.
Seems worse on windy days.
There is air leakage spot just before air goes into the vents
, and that is what I am looking for the diagram for, so I can tell you where.)

Make sure the combustion air pipe to booster motor (small vent motor) is not damaged, clogged or leaking air.

Make sure the booster motor is running strong and it and wheel are clean.

Make sure tubes from motor to pressure switch are not kinked, clogged loose or damaged.


Make sure you have 24VAC to ground on one of the two wires connected to pressure switch.


Thanks,
Robert
