Overview of XE90
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.

I read a lot of negative reviews about the Trane furnace which I can
only assume was either bad installation or just plain bad luck. Because
I have had my Trane xe 90 for over 24 years and have never had a service repair call on this furnace. None. I'm not kidding. I've had it cleaned a couple of times over the years and that's about it. When I need to replace this unit someday, I hope they are still making them with the quality that I got with this one.

I read various reviews and it appears that other users are either very
satisfied or very unhappy. I can't explain the the differences but all I
know is my Trane gas furnace (Xe90) is 24 years old and I have never had
a service call on it. All I've done is cleaned it and changed the
filter. It has run completely trouble free for 24 years. When I finally
replace this one I will be looking at another Trane. It seems these days
that most products are not made like the older ones but I hope Trane

After exactly 20 years of service the blower motor of my Trane xe90 went
out. Upon closer inspection the heat-exchanger was cracked in 2 places.
If Trane is supposed to be a higher end product 20 years of service
falls short of expectations.

Don't buy Trane
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
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!

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.

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

Undependable on cold winter nights
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.

Jump on the Trane !
Couldn't be more statisfied. Trane has gievn me no problems. New system is quite and efficient. I can feel the difference in the house this last winter. Temp stays constant with no swings. furnace never seems to have to work hard - it makes is 'sound' easy. I also got the Trane CleanEffects, its worth the money. I've even noticed less dust on the furniture.

This Trane keeps on running
Had a new XL90 2 stage furnace and Air Effects cleaner installed before last winter. No problems all year...works as promised. It seems like the furnace never had to work hard all winter, our last furnace always seemed to be working at full capacity (I guess its the two stage blower). Regardless, would highly recommend

Trane missed the Train!
Xe90 is poorly designed! The computer board is not encased. It's mounted
below the condensate lines and in front of the blower. Therefore, if
there is any condensation, a discharge line backs up or a-coil drips at
all. The water hits the blower and fries the board. How about 4 of them
in the past 5 years! Not to say the electronic ignition went out as
well. The design is poor! I have a 2 ton air conditioner which can not
keep up to a 1200 sq foot house! Never buy a Trane again!

I have a Trane xe90 and it has been a problem since day 1. Constantly
cutting out and needing to be reset. Never consistently running in
the winter. Shutting off for hours at a time and when it does start
it doesn't stay going. As they say, "Nothing starts a Trane" or it
should say that.

TRAIN DOES NOT STAND BEHIND THERE PRODUCTS
We have 1o train units at our church. And all 10 of them have the same problem. At the motor where
the wires go into it, the wires are being rubbed and cut into because train or
Bryant heating left the rubber groment out. We
started looking at it and saw that the blower motor was completely
burnt to a crisp. It was black it blew the fuse and breaker. Would hate
to think if one of the breakers or fuse has failed. I could see if the
furnace had this problem but all 10 are cutting into the wires and I
wonder how many more are out there are like this, if all 10 of ours are cutting into
the wires. We have called the installer and they have contacted Traine
and no reply at this time from them. I think this could be a fire
hazard. I donít know for sure but someone could at least call to offer help
or at least give a price on repairs. I think their needs to be a recall
on the furnace. Customers with children need to have this Traine furnace
checked model tux100c960c upflow/horizontal direct or non-direct vent
gas furnace like I said I could see 1 out of 10 with this problem but not
all 10 and Iím sure their are thousands of them out their. Please if you
have this model have checked even if you have to pay for the service no
child is worth loosing
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.
Why does my Trane XE 90 show 4 blinking red lights?
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.
The XE90 is available in different models which vary in efficiency and capacity.
