Hello All -

I have a Coleman Evcon - Model DGAT070BDD - last night I heard a rather ominous buzz coming from the unit - electrical in nature. The error code light on the circuit board is flashing constantly - no number of flashes in a cycle, just non-stop flashing. No response from the unit - no fan, no heat, nothing.

I noticed about 10 minutes later that water was leaking through the combustion air vent, dropping right onto the circuit board.

Does the constant flash indicate a dead board? Any suggestions on how to troubleshoot the circuit board?

Thanks for any and all guidance!

Darren

Update: tried again today. Green light solid - unit responded to fan on. Later in the day - buzz is back - no response.

I'm guessing damaged circuit board.

I see no one got back with you. Did you ever solve the problem?
