Trane XV90 Gas Furnace Inducer Problems
I had a new Trane XV90 Gas furnace installed in my home in the spring of 2003. Since the install I have had the inducer replaced 7 or 8 times, 4 times alone since November 2010. I never really worried about this because my Trane furnace came with a 10 year parts and labor extended warranty so I wasn't being charged anything for the repairs. Now I'm beginning to worry, I just had the Inducer replaced again yesterday and I realized that if this problem continues, I'm going to soon be on the hook for the repair charges associated with this issue and it's not cheap. Does anyone have any idea as to why this may be happening? What can I do at this point? I contacted my HVAC contractor, they are the same ones that installed the unit and have done all the repairs. They said that they're no longer a Trane dealer but they would still call them to see if there is anything they can do. I think I'm going to start a letter writing campaign and blanket the entire Trane company. I was hoping that maybe they would extend the warranty out another period of time just for the inducer. I don't expect them to cover anything else because I know things are probably going to start going out on a 9 year old furnace. Has anyone else had this issue and what if anything should I expect from Trane? Thanks! What have been the symptoms of the problem ascribed to the inducer motor? what is the model number of the furnace? Has the furnace had the upgrade kit put in? The model number of the furnace is: TDY100R9V4W. Also the upgrade kit was installed in 2010 and we have had the inducer go out 3 times since that change. The symptoms are that the furnace starts to make a loud whining noise and growls like a bearing is going out. Also, the furnace seems to labor and struggle to get going going. Sometimes when the furnace is turning on it will start up and shut down like 30 times before it will actually start. It starts going for 15 seconds and then stops for 15 seconds and repeats that for 5 or 10 minutes all the time sounding like a wounded animal that needs to be put out it's misery. Also when this is happening, I get the red blinking light, 3 flashes and then a break over and over. Right now the furnace is working great and is whisper quiet but that's because the inducer was just replace a few days ago. I'm worried that in 2-6 months and I'm going to start having the same problems all over again. your contractor needs to call tech support to determine the cause of the multiple inducer failures. It may be a board problem sending bad voltage, it may be a slow drain that is causing excessive condensate in the inducer. One thing I'd due is to check that the correct voltage is being applied to the inducer motor when those symptoms are occurring. Seattle that may be hard as it is a variable speed DC motor. The control is in the main control board. Oh Kay. Hmmm. Sounds like all the more reason to try to identify what voltage should be applied, though. A circuit board that isn't providing the proper voltage might wind up damaging an inducer motor after a while. But I'm just guessing. I've never seen THAT MANY repeated failures of a part, but there's a first time for everything. because the voltage will vary to change the speed of the inducer, there is no way to know what the actual voltage should be. the control board varies the inducer speed based upon 2 items, 1: what stage the furnace is firing in, 2: what voltage or speed at which the pressure switch has closed and or opened at. Have your contractor get to the root cause of all the inducer failures! Inducers don't fail that often unless there is an underlying cause.
