I am new here but I hope I can find some help.
I have a Trane XL80 and up until last night it was working great.
Now I get no heat.
The status LED is blinking two time.
I can see the igniter lighting up, however no flame.
I Checked for voltage at the valve, I meter 24vac for about 2 seconds or about the same amout of time as the igniter is lit.
