Here is the sisu. Here is the situation: Trane XR90 gas
Here is the situation: Trane XR90 gas furnace installed in 2010. Had trouble with it shutting off intermittently when it was running resulting in the three blinking lights. If we pulled the pvc intake tube out of its socket on the furnace once this happened, the unit would work without trouble. Called technician in after a year or so of this and tech spent several visits investigating the furnace. his solution was to cut the intake pipe off about 1 foot from the furnace so intake came from air in the basement; not outside. this has worked without trouble for several seasons. // We are now remodeling the basement and need to get the furnace pulling fresh air from outside instead of air from inside the basement to satisfy building permit inspectors. My contractor thinks the original trouble was that the intake piping had 4 90 degree turns in it making intake air intake problematic. I have the chance now to re-do the intake pipe on a different route to outside with just 2 45 degree angles. Would t his be a good solution that would have a good chance of fixing the issue? I assume thats since the tech spent so much time investigating the unit and the situation (and that his solution worked) that there are no internal issues with the unit causing the shut down. Thanks in advance for your reply. … read more
