Trane XR90 - 3 Red Lights


OK, the guys came back today. The poured 2 buckets of water down the exhaust pipe from the outside and they said it looked like there was a problem in the collector box with the drainage.
They didn't bother video snaking the intake because they said they called Trane and they told them it probably wasn't that.

Then they left and called Trane. Trane told them to tell me to call the people who installed it because it might be a warranty job they (they guys I called) were not authorized to do this repair.

But first i am going to try and clean the trap and that other part Harley mentioned in his post to clean besides the trap and if no luck I will call the original installer, who I had actually called first but they told me it was a week wait.

So really I am back where I was when this started.

I am convinced that its the heat exchanger, same problem as in the video's.....Tom you can call ANY Trane dealer, it does not have to be the original ones that installed it. Do you know when they poured the water in, did it run out in the blower compartment? Please keep us posted

I always call tech support while I'm at the job site. Don't always get through, but 98% of the time I do.

Tech support always wants this that and the other thing checked. And generally ask the techs to do this while they are on the phone with them.

Don't know why anyone would leave a customers house and then call tech support.

Spoke to my installing dealer and told them what the other guys did and they want to order a "cold header". This is before they even look at it, just by what I told them (the other guys tested the switch, inducer and exhaust).

I just find it a little odd that no one wants to examine the intake pipe.

Thats OK Tom, let them swap out your heat exchanger (its made in an era were they were known to fail ) then if/when it still doesn't work then they can check the pipe....... If the pipe is accessible, you can "X-RAY" it by holding a bright light on 1 side, and anything in the pipe will cast a dark shadow on the other side of the pipe. Its not fool proof, but i have used it in the past to find tennis balls, sand from the sand box and dead chipmunks.

I think they are only ordering the "Cold Header" - I am under the impression this isnít the entire heat exchanger. The service manager called me back and he seemed to know what he was talking about, but I think he is calling the cold header the transition piece from those videos. At least it's under warranty, just not the labour.

They don't send just the "cold header" you are getting a whole heat exchanger.

For anyone who cares, here is an update on this.

Today, the job was finally completed.

A couple of weeks ago they guy came with just the transition piece (plastic part between the inducer and the 2nd heat exchanger). The screws from the factory cracked it. But it was really obvious more was need as once he took off the inducer we could see lots of rust and corrosion and a crack from the dripping corrosion on the front plate of the 2nd heat exchanger. So we still had a code 3 after the part was installed.

So today he came back with the entire heat exchanger and installed it and so far everything seems to be running fine.

I just wanted to thank everyone who posted advice and especially thank HarleyRider. Your advice was spot on and invaluable, it really helped me a lot on dealing with this.

Cheers!

Glad it all worked out, and by now you almost have a new furnace again....what you was witness to early on in this problem, is a problem we are dealing with nation wide......unskilled techs that seem to refuse to pay attention to the obvious.As well as company not requiring the owner ship of essential tools such as digital manomators, gas pressure gages and thermistors for measuring temperatures.

Most of these kids now a days want to read a blinking red light change a part, and make $30 dollars an hour.Thats just not going to happen. Thats why i stress always insist on the older guy, with all the proper tools when calling for service.

They dident charge me a penny for the international call either.......lol
