    It could be anything from the control board to the ignition systems. All must be checked.

TRANE XV90 error code? [ 4 Answers ]

The owners manual does not have a list of error codes for reference. The unit does not actually display a code (no pause), the light consistently blinks. I have never noticed this before, is this normal or something that should be looked into. Thanks!
