Hello, I've been having trouble with a new Trane system I got installed two years ago. Here are a few details...

Model: GAMB0B36M31SAA
Heater: BAYEAAC10BK1AAA

I believe it is wired at 240V, and I've been having issues with the heater. I had a technician come over and look at it and he found it was the "heat limit", I believe. He said it was open and would have to be replaced. The power went out a few weeks ago and I noticed that is when the heater stopped working.

The technician believed that perhaps the heating elements were overheating due to not enough air and this blew the fuse. I was thinking it was the power surge since the heater was running fine for at least 3 months. I have a 10 year parts warranty, but the gentleman was quoting $180 in labor. So I got to digging and started looking through Trane's manual for the GAM5B air handlers.

The issue comes when I look at their air handler and heater matrix. I don't actually see the heater that the company installed on that list of acceptable heaters for my particular air handler. I don't know if this is a big deal, but I was just curious if that could be causing an issue? Also since the part is covered and I have worked with electrical equipment before, would replacing this open heat limit/limiter be a difficult task? I would really like to save the $180 and get some differing opinions.

That heat kit will work with your air handler. Was the hi limit opened when the A/H was off?

I believe it was, because I remember the heater stopped working immediately after the power went out. So I was thinking that it wasn't due to overheating, but due to some kind of power surge when the system came back on. How difficult would it be to replace this part if I picked it up from the HVAC place?

The more I research and the more I inspect the installation I'm starting feel like I got not the sloppiest workers, but some sloppy workers.

Normally Hi Limit's are not difficult to change.

Excellent, well they ended up calling back and saying they would do the service for free because the technician should have changed it while he was there, so I have to put up with these people coming into my house again and annoying me to death.

That's good news. Let us know what happens.

Probably the best news I was going to get, I appreciate the help and I'll keep you updated on how the repair goes which should be early next week.
