Combustion air switch

Postby YB Norml » Thu Nov 06, 2008 10:47 am

I have been lurking on this forum and have found answers to my questions until now. I have a Coleman model # DGAA090BDTA that we turned on for heat a couple of weeks ago. I got the 3 blinks that indicate that the combustion air switch failed to close. I purchased-thru the catalog part # 024-27666-001-the switch and installed it. Turned the furnace on and got the same 3 blinks. I can induce and hold vacuum on the - side of the switch and the furnace will fire and run. When I release the vacuum the furnace shuts off and I get the same 3 blinks as error code. Any help would be appreciated.

Thanks in advance

Hi,

Check air pipe for blockage, be sure booster motor is running, check small hoses for kinks, blockage or damage.


Thanks,
Robert
