  1. Don't Buy Trane! 1 Star Review

    Posted by on 12th Jan 2013

    We have an older model Trane ComfortLink II, installed in mid 2009, with a (limited) 5 year warranty still in effect. We're having some real problems with the touch screen. It doesn't work on four days of the week (Sun-Wed). The only way to change the heat setting on those days is to change the Schedule (the hours the heat is on and off). I called Trane Customer Service and their response was: "We don't answer technical questions here. You'll have to contact your local Trane accredited service person." In other words, pay a local furnace company to troubleshoot the problem. I find their attitude less than helpful when their own web site troubleshooting section on this product doesn't mention any such scenario as a possible problem. I have read over the book that came with the thermostat and according to that there is no possible way for part of the screen to be locked unless a "SCREEN LOCKED" notice is visible on the display. The thermostat has worked fine for 3-1/2 years. Now I have a problem and, seemingly, no recourse for an expensive product under warranty. As a retired Industry businessperson, seems to me they'd send out a Rep under these circumstances.

    Anyone else having problems with their 2009 Trane ComfortLink II Thermostat?
