I have a Trane XR90 furnace with no ignition. Four blinks on the control board.
I've tried changing the 15 uF capacitor, cleaning my electronic filters, and putting a paper clip between the high limit leeds.
Nothing gets rid of the 4 blinking light pattern. Can this be caused by a bad ignitor ?
Running out of ideas. Please HELP.
