Coleman DGAT056BDD No Action

I just bought a park model trailer out at a local lake, the furnace looks like new but we can't get it going. I checked the gas supply and it is fine, I checked the circut board and the green light is flashing constantly. I looked in the manual and it says reverse polarity, where do I begin checking to see if this is correct?

At the board and backwards from there to see if hot and neutral wires have been connected backwards with each other.



Thanks for inquiring,
Robert

Thank you Robert, any idea where I can find the proper wiring diagram for this circut board so I can double check things? If the wiring is backwards, will it have screwed anything up trying to get the furnace to run?

Hi,

You're very welcome. You can get a furnace wiring diagram here if needed:

It shouldn't have harmed it, but really depends on situation and how long it has been that way.




Thanks,
Robert
