I have a Trane XE80. Came home tonight and it was cycling thru the startup process, but no heat. I examined the error light it was flashing three times, then nothing then three times, etc. Indicating a pressure problem. Ipowered off the unit, tested the pressure switch, cleaned the tube and wiped the rollout sensors. powered it back on. I noticed the fast flash and electric ignitor lighting up but no gas flame. After a while the fan kicked on but no heat. Now when I turn the thermostat off the fan just runs and runs and the red light blinks twice over and over.

What's going on? How can I debug this?

Bueller?

We had a thunder storm pass through yesterday afternoon. I'm thinking the circuit board somehow fried.

Anybody know how to test it?
