Another Cracked Heat Exchanger

One would think that after discovering that the plastic collector flange, (that Trane considers part of the heat exchanger), routinely develops "cracks" where it attaches to the plastic "transition piece", it would have issued a factory warranty on the defective part that can lead to moisture leaking onto the control board, or worse, leakage of deadly carbon monoxide. It would appear to me that the crack was caused at the factory when some knucklehead overtightened the screws connecting the transition piece to the "collector box", causing the screw attachment knob to develop a crack. So, a $1.00 piece of cheap plastic now necessitates a $1200 repair or a completed replacement. What a scam! What a racket! Shame on Trane and their "trane-wreck".

Should not have replaced so soon

Bought two Train furnace A/C units 7 years ago. Had them serviced for A/C and found that in both furnaces the condensing coils were gone and had to be replaced. The second furnace also had the heat exchanger cracked and it had to be replaced also. With the cost of these items, we decided to replace the second furnace and A/C unit. Needless to say, we did not buy a Trane. Both of these units should have lasted longer than 7 years. Contacted Trane and got no reply.

Great Buy

I own over 50 rental houses and have installed Trane systems when I updated the hvac systems in many of them. I have an installer that I trust to do the job right, they have never let me down in the last 20 years. I've purchased over 30 hvac units from them for my properties through the years and they will not install anything but Trane. I can attest to Trane's dependability, as a land lord they are trouble free, never get service calls from renters on these units. I have also used the fact that I have efficient Trane equipement as a selling point. If you having issues with your Trane equipment I would first look to the installer, not the manufacturer. Never go cheap on your installer or you'll eventually pay.

Pure Crap

This was installed six years ago in new construction. It never performed well, the house took long to heat and cool and the temps were uneven around the house. This fall it began operating intermittently and erratically. Note that the warranty is five years. After three tech visits and $400 later it was discovered that the heat exchanger was cracked. Took some work to open it up and use a mirror on an extension rod but I saw the four inch long crack. Luckily it was guaranteed for life (however, $740 in labor to replace) but it is not available for at least a month, maybe more, in the dead of winter in Seattle. The crack in the heat exchanger makes the burner box run too hot, it shuts down after ten min triggering the high limit switch, it also has difficulty starting up because the draft inducer can't produce the necessary pressure, a condition also created by the cracked heat exchanger. The circuit board is also operating intermittently, giving false signal that the high limit switch is open (four flashes on the diagnostic led on circuit board). The tech says it is a weakness in all Trane products. How about $400 for an upgraded replacement board? The dealer says we can replace the entire unit for $4000. The factory support has been non existent. The Trane web site sucks and they avoid any human contact. I am looking at other brands this week. My Trane Model # tdx1d120a9601ab, serial # 6302hbb7g.

Trane XR90

I had this Trane XR90 for ten years. Every part in it has been replaced more than once except the heat exchanger. Now the heat exchanger is leaking gas and carbon monoxide. Learn from my mistake. Buyer beware!

Throwing control board bad code

Our Trane furnace is just over a year old. Top of the line last year. We have replaced the transformer and the board. It is getting power to everything, but it is still showing the control board bad code(a new board was just put on today with a new transformer). What can cause this? Please respond asap as even though its "Spring", we are still getting snow and very low temp. Thank you.

"How to Stop a Trane"

This is how you stop a Trane. First of all you have to do is give up your hard earned money to purchase and install a Trane furnace. will seem like a smart decision at the time because of their marketing however you will soon learn that all the hype is just that...HYPE! Now to stop the "Trane" all you have to do is wait and it will stop all by itself! In six years of ownership the motor control board has stopped working twice! The repair is over $350. They do not stand behind the warranty they offer up front and they do not know the meaning of customer service. The best thing to do is don't get one in the first place. I am now the proud owner of a $3000 Trane XR90 boat anchor because I refuse to give them anymore money and have it repaired...again. I have however come up with a solution for my predicament. I'm getting a new furnace from a competitor. Save yourself the grief, inconvenience and cost. DO NOT BUY TRANE HVAC EQUIPMENT...PERIOD!

I called the customer service rep when my problems began and received no good answer from anyone. We purchased the unit in 2003 and have had problems ever since. I think with all the service calls I have paid for the furnace twice. 5-10-06 venter motor, 9-16-06 pressure switch, 4-23-07 flame sensor. 5-02-07 Same problem, 5-09-07 venter motor again, 5-18-07 heater exchange, 5-25-07 venter motor again, 10-16-07 venter motor again, 4-22-12 3 burners, 4-23-12 gas valve. This time we got stung for another $480 dollars. With all the service charges of 80 dollars for each service charge I feel we have almost paid for the furnace twice and as far as any help from the customer service dept. They gave us no help at all.

Best I ever had

Changed out my old Lennox for this Trane XR90 also had the ac installed and never had any problems. Change the filter once a month and it runs great!!! Would buy another one in a heart beat.

Had a Trane xr90 installed 7 years ago, been great. Extremely quite with the variable speed fan....I've had to go to the basement to see if it was running. Always has been. No temp. Swings and no service calls. Been a great product. Highly recommend.

Trane XL90

I have been very pleased with the Trane equipment. I have had other brands and Trane has proven the most reliable and least expensive to repair. I have regular preventative maintenance every year. The installing contractor has more to do with the performance than people give credit!

Trane is quality

Replaced old Trane furnace that was 25+ years old with a Trane XR90 unit. The old unit still worked, it was just time to get a more efficient unit. I expect that same quality as my prior Trane, time will tell. The new system is only three years old. So far everything works as promised. Quality builds loyalty and I'm sold on Trane!

Top Quality

New furnace installed 2 years ago and works perfectly. I've had probably 5 different furnaces in my life: Carrier, York and Lennox. I liked the Lennox, but this Trane is a top quality furnace. I've seen savings in my gas bill and I can almost not hear it run at all. The fully modulating gas was a major reason I went with this model, expecting savings that only that techology could offer and was not disappointed. Highly recommended.

So far, we have had good luck with our Trane xr90 High Efficiency and AC. We have had no problems. We have a large house over 120 yrs old, 2200 sq ft, and right now the gas company owes me almost $600.00 This is the second year for being on budget with the gas company. If you have problems, it is probably due to improper installation.

Trane XR90 not working

Woke up to 56 degrees and cold air blowing out the vents this morning. Had our Trane xr90 for 6 years. Nothing but problems since. Every single winter, it craps out and stops heating the house and requires maintenance. Everything under warranty so far, so that's good. My fear is in another few years when warranty is up, what happens then? I guess, I will be screwed and just have to pay for parts and maintenance each winter to keep this lemon running. Nothing runs like a Trane - what a joke.

Poorly engineered furnace.

Sorry but xr90 Trane has been a problem since year two of installation. The firebox was replace due to leaking water from within - false starts - up to six times before igniting caused the following changes - a mother board - a programmable thermostat - when I believe the bottom line was insufficient air from the inlet tube the major problem. The breaking point was failure of the air conditioner compressor fan recently. Installing a Carrier Infinity series gas furnace with a 95% afue which includes a long warranty period.

Other XR90 Reviews

Posters on this HVAC forum debate the qualities of Trane, Carrier, and Lennox and most seem to agree that Trane comes out on top where quiet efficiency is concerned but loses in terms of price. Most believe that proper sizing of a furnace and good installation is more important than the brand.

Question and Answer


What is the red flashing light on a Trane XR90 furnace?


The flashing red light is an error code, meaning something is wrong with the furnace. The sequence of blinks is a code that can be used to troubleshoot the problem. There is often a diagnostic code list explaining the sequence of blinks on the inside of the front panel.


What does an error code of 9 flashes mean on a Trane furnace?


A red light blinking 9 times refers to a problem with the igniter. There may be a diagram explaining the error codes on the back of your unit's front panel.
