|Atwood 8940 furnace: wont stay running. Need help||Tim||4-7-13|
|Hi. My stats. Atwood 8940-111ACLC.(2008 Breckenridge). Furnace will only run if furnace inner door is open, either slightly cracked or wide open. If closed, it shuts down. Ive replaced|
circuit board w/ a Dinosaur 24 VAC. I wonder if its a sail switch? Seems like its an air intake thing.
Help! Any ideas?? I want 2 open soon & nd heat.

|IT COULD BE BUT:|
It is more likely an air flow problem.
Restricted air return. Plugged or dirty blower wheel.
Old worn Motor not running fast enough is the most likely thing.
