Cheryl most of these furnaces have a control board mounted on blower housing .On that board there should be a status LED light.When furnace fails the light should blink a certain number of times to indicate what has failed. Can you look and see if the light is blinking and if so what the pattern of the blinking is? That will help us in knowing where to start.

Hello are you still there, it took me a while to go to the garage, and up to the attic
Expert:  airheatman replied 1 year ago.

I am not that familiar with zone systems, did you look in furnace itself in blower compartment for a code or just on zone panel?

Customer: replied 1 year ago.
Trane XB80 is not the number you need?So I'll go up and look inside the blower & the zone panelIf you would call me I will go upo there and stay for continued follow upThanks Cheryl

Expert:  airheatman replied 1 year ago.

No. Do not click on a rating button until you have received an answer and are 100 per cent satisfied. That is why I did not accept call as I am not sure I can help. Wait until you have received the answer before rating.If no one can help, you may request a refund and are credited .

Hello, a diagnosis will require you to use a multi meter (electrical test instrument).. if you have that and some background I can coach you through a diagnosis. The chance that this is a simple 'reset' issue are in the 2% range (two chances our of a hundred). Let me know if you feel up to digging into the electronics etc or not or if someone else in the family wants to go that route.

These are complex systems, the training is 2 years in a community college 20 units a semester and then 2 years in the field practicing under a journeyman... then for most techs, two weeks a year in factory schools studying all the new developments.

What you can do yourself is limited or enabled by your technical background... if you have some of the basics under your belt, such skills with appliances and car repair I can often coach a person in that category to an accurate diagnosis and repair... thats usually a 2 to 4 hour project however..

Let me know if you think that approach is suitable to your skill set and we can go from there, if not, tell me which direction you are from the center of the nearest town or city and I will see if I can locate a well established and well rated outfit that can do that for you.
