Heating, Air Conditioning, Fridge, HVAC/Thermal switch on Trane XE70


Sorry Craig.  I thought you might have the schematic.  Does ANYONE at this service have prints or does Trane keep them "close to the vest".  If Trane does then I'll contact them but their service costs ($) and this service is free. Please let me know.

Trane does not hide anything.  They, like most, do not really make the info easy to get for homeowners.  They want homeowners to have to call for service and not make repairs on their own. The diagrams normally come with all units.  I find them pasted to the inside of the unit or with the owners manual.   There are websites out there that might allow you to buy parts.  They should have access to the info. You are going to need more then just the few first digits of the model number.

I have been in the HVAC field for the past 18 years. I can help with most HVAC questions. I work on commerical buildings for the most part, and have yet to find anything I could not troubleshoot and repair, when repairable. I work on small 1 ton units to a 2500 ton chiller. Troubleshoot air flow, elect, and control problems. I attend regular classes to keep up with the latest and greatest.


I work on commerical sites, hospitals, gov't buildings. I can troubleshoot just about anything in the HVAC business.

5 years trade school, VFD training classes, Liebert factory training, some York and Trane factory training.
