Hello folks! Yesterday after coming home from work I noticed the house was a bit chilly. Noticed air was being blown but it was only cold air. The following is what I know and what I have looked at. 1) Heat is commanded vent motor fires up. After about 6 seconds vent motor shuts off and main fan blower kicks on. No flame, no ignition... 2) Error LED flashes 6 times. Supposed to mean 115VAC reveresed polarity or bad ground. 3) I checked all powerI have 120VAC.. getting to the circuit board. I have 120VAC on Primary of transformer and 27VAC on secondary being fed to CB. 4) I have no voltage ever getting sent to Gas valve or ignitor. Have clean filter shorted out safety switched one at a time same results. This one is bugging me I am not sure what the cause would be... I am thinking it may be the Circuit board but I don't know. About ready to give in and call HVAC tech but any other advice would be welcome. Regards, Tom Spokane, WA

6 blink codes is from the control board indicating the problem..... Computer never lie. Check your ground and polarity.
