Long Battle with AC/Furnace/Heat Pump Issues

Glad you found your problem, But I will say this:
I have an atwood "Hydroflame" furnace (no heat pump).. The OEM control board uses a single wire for both high voltage ignition and flame sense,, Efficient design but... What happens if the change over from MAKE SPARKS, to SENSE FLAME, goes wonkey and you hit that flame sensor chip with around 1,000 volts...or more? (NOthing good I can assure you).. I believe that is what killed my board.
I replaced it with a Dinosaur board... They are highly recommended by others so I got one from American RV in California, Less than half the price of the OEM board it was.
I am a trained Electronics technician
First thing that struck me when I opened the box was the QUALITY of this puppy, makes the OEM look like junk (Well the oem was junk at this point)..
Then as I looked it over more closely there on the board is a device (Gas Discharge Tube) that is one of the devices used to clip voltage spikes on electric circuits... Right next to the flame sensor chip. Wonder why that's there? (NO I DO NOT, I know why it is there).
RV purchased Spring 2005
Board replaced 1st of 2012 (Failed in fall 2011)
Expect to replace it again... Actually, I do not expect to replace it again.
