DGAT056DBF won't turn on
Posted: Sun Mar 30, 2008 2:51 pm
I have a DGAT056DBF Ser# 02427666000 1999 vintage.
In Auto Heat the problem light first comes on steady green, I hear a click and a hum then get a second click at which time the problem light begins a series of three flashes indicating "Combustion Air Switch Failed to Close". I ordered from you and replaced this switch but the problem remains the same with the new switch.
It is a combination Heat/Air Conditioning unit and works fine in Air Conditioning mode of operation.
The hoses to the Air Switch are tight and in good condition.
I would greatly appreciate and ideas on further troubleshooting of this problem.
