Trane XE90 Furnace Overview

The Trane XE 90 furnace has an AFUE rating of more than 90 percent, meaning that 90 percent of the fuel you use is directly turned into heat. This gas furnace has a patented heat exchanger that is designed with a serpentine-shaped channel. When air flows over the heat exchanger, hot gases are pulled through the channel by an induction vent fan, rather than escaping up the flue. According to the manufacturer, then thin exchanger features low air flow resistance, which in turn means that there is less work for the blower motor.

The Trane XE 90 has a self-diagnosis capability that utilizes a controller search system to identify any problems that need to be resolved. When there is a power or fuel interruption, the system is designed to reset automatically.

The unit is available in upflow and downflow models. The hot surface igniter replaces a pilot light. A heavy-duty, fully insulated steel cabinet was designed to reduce noise and further lower heat loss. The manufacturer also notes that the unit’s 40-inch high and 28-inch deep cabinet was designed to fit nearly any space.

"Don’t buy Trane"

1.0 rating
Very Unsatisfied

I have 2 Trane XE90 furnaces, put in year 2001. Both have been complete junk. Nothing but problems. If it wasn’t for the 10 year extended warranty I bought, I would have been in for a lot of $. Now out of warranty, both units failed completely at the same time at just only 14 years old. Nothing stops a Trane, don’t buy it.

"Happiness is a Trane"

Very Satisfied

Built our house in 1994 and had a Trane XE90 installed. This unit has given us years of reliable service and I have not so much as replaced the filter on it yet, though I know I should! Seriously though, this unit has proven highly efficient and economical! We really got the most for our money with this baby!

"Problematic Trane"

1.0 rating
Very Unsatisfied

My Trane furnace was installed new in September, 2001. I live in the San Francisco Bay area where the weather is not really hot, nor does it have extreme temperature fluctuations. During the winter months, the furnace is used to heat a three-story home which was built in the 1970’s. Starting about two years after the furnace was installed, there was an intermittent problem with the ignition start up where the first phase of the process would begin and run for about 15 seconds and then shut down. Usually, I would manually start the furnace up again from the thermostat and the unit would start running properly. I did this for another two or three years, where the problem became more acute and I decided to call in a professional. Now, there has been a professionally-trained Trane repairman at the door and still this problem does not seem to be addressed. After inspecting the exhaust pipes and intake, taking out all the little hoses, looking into the combustion chamber, checking for loose wires, looking and taking apart the drain hoses and putting it all back together, the unit will run correctly for a day and then start acting up all over again. During the last visit, the pressure switch was replaced for $245.00. The new switch is made by Honeywell. It, too, worked intermittently, and after three days was even worse than the original unit. I was waiting for the repairman to come back for another search (this would be the sixth visit) when I decided to put the original pressure switch back in to see if it would work better than the replacement. So far, the old switch is now working, but I suppose that it will once again start acting up as before, with intermittent success. I noticed that during the initial first phase of the start up, when I disconnected the upper hose to the combustion chamber or the vacuum switch, the unit would start the gas, and fire up the furnace and then the blower. The Trane XE90 seems far too complicated and it is a bothersome and unreliable piece of equipment. If it comes to a replacement, I will not purchase another one to take its place. Buyer beware – don’t believe the review “Nothing stops a Trane”. As far as I am concerned, “You’ve got to start the Trane before you can stop it!” Don’t buy a Trane… you will regret it. I’m sick of this one.

"Solid performance"

5.0 rating
Very Satisfied

1996 installation. Has provided reliable heat for the 10 years we have owned it, including a few years with no professional attention except filter replacement. We are currently selecting a replacement furnace for our cottage (40-year-old electric Lennox) and based on our experience with the Trane, we will likely get another. Both had been installed by larger firms, which is probably more expensive but their longevity is a testament to the make and installer.

"Undependable on cold winter nights"

2.0 rating
Somewhat Unsatisfied

The furnace is installed in my garage and when the temperature drops to 5 degrees or below, the unit’s pressure switch fails to allow ignition. The furnace continues to cycle through the startup sequence but will not achieve ignition and main blower startup until the temperature rises to above 5 or 10 degrees. I was never successful in determining the exact cause and in fixing it.

Other XE90 Reviews

One writer at justanswer.com shared his problem with his Trane XE 90’s intermittent hot air operation. From time to time, his furnace runs even when the furnace box is not lit, so that cold air is forced throughout his house. Through discussions with other posters, he discovered a way to bypass the furnace fan limit operation that solved his problems.

An HVAC systems user at hvac-talk.com had a similar problem. This forum poster had a professional technician install a new pressure switch, which did not seem to solve his problem. Experts on the forum said these problems are rarely the fault of a pressure switch, and that the owner might instead check his furnace’s intake pipe to check for clogs and ensure that all drains were unplugged.

Question and Answer

Question:

Why does my Trane XE 90 show 4 blinking red lights?

Answer:

When your Trane Furnace is blinking a red light, it usually indicates there is a problem with the furnace. Different flash patterns indicate different problems. There is usually a code identification list located on the inside of the panel door. Remove the door then identify the blinking pattern compared to the list on the door. That will give you a short description of the problem the furnace is experiencing. Keep in mind the list does not provide solutions to the problem, but it should get you to the next step.
