It's a Goodman problem

[woodheat]

Need help Folks.
I turn thermostat control to On/Heat.

Turn up the thermostat control setting to 70 degrees. Draft blower relay clicks , it starts up. 5 seconds later the relay for the Igniter clicks and the ignitor comes to a perfect Red glow, and I hear the gas valve relay click and it doesn't open up and it repeats this cycle twice.
Shuts down and the Status light blinks continously, indicating reverse polarity on the transformer(I tried that, Nothing) or twinning problem.
Could there be a short in the Thermostat control wiring causing this, or is it a Bad relay on the Mother control board? The furnace is only 3 years old. It's a Model GMNT 060-3, 95% effcientcy LP Gas Horizontal upright Model.
I'd appreciate the help. My wife and I are both handicapped(Limited Income) and sure would like to keep our costs down.

Cleaned contacts on Computer board and ignition switch and Ignitor. Got a pressure swith stuck closed status light.

Cleared vacuum Line from draft induction motor to Pressure switch. Now My status light is saying, Just igntition failure, or Gas Valve. Also checked exhaust line and made sure it was clear. Still no Gas?

I used to do alot of work on Farm furnaces on the Cow milkimg Farms I worked on. I don't have the Ohm meter anymore , need to get one, and I don't have any gas Line pressure testing equipment anymore. I also used to work maintanance for a Butcher plant. And I worked on 440/660 electrical systems, etc. Plumbing, High volume shower style Gas Water heaters, Mill right work. Boiler maintanance, AC/refrigeration monitering/ Sometimes helped
Their HVAC specialist with it.

Some of the Condensing Coil pacs I had to Braze into place!
Some of them were 8 ft. long and 3 ft. tall ! The HVAC Monitering I was allowed to do, was checking The computer stayus outputs. I wasn't allowed to adjust them. But I was taught what to look for and Call the HVAC supervisor if any of them were running out of their parameters.
