"Trane XR80 is Crap"

1.0 rating
Very Unsatisfied

After two years in service, the circuit board and transformer failed on my Trane xr80 and thus needed to be replaced. Although under warranty, it still cost me $350 of labor and warranty service fees from an authorized Trane dealer (highway robbery at its best). My other unit is a Carrier–it’s been in service for 13 years–with no major service required. The TRANE XR80 is a piece of crap!

"I Hate This Furnace"

1.0 rating
Very Unsatisfied

The Trane xr 80 is a complete piece of sh**. Every single year, I have to get something fixed on this thing. I change filters every 30 days, clean the flame sensor every year and maintain it as well as can be expected but every year since it was new something goes wrong and leaves me without heat. Right now for some reason, it has blown the original transformer and 3 weeks later has now blown the second one. Why? Who knows, I will never buy another Trane product, complete and utter garbage. I wish I had got a 300 dollar Janitrol instead, so at least when it started acting up I could blame it on being cheap. STAY away from Trane!

"New Trane Furnace/Humidifier will not work"

5.0 rating
Very Satisfied

I have a new Trane xr-80 gas Furnace and Humidifier installed July ’08. Did not turn on until October. The thermostat is set on #5, which should provide 45% humidity. It will not go above 30%. The dealer’s service Tec´┐Żs have been here three times. The last time the rewired the Humidifier so that it would run when the fan only was on and advised to run continuously. I ran for 12 hours and the drain line was outputting 4 gallons per hour, the humidity remained at 30%.The tech verified that my humidity gauge was correct!

Question and Answer


I see a red light flashing on my Trane furnace. What does that mean?


Your Trane furnace has a flashing light to tell you if your unit is functioning properly or not. A steady flash is normal and means the unit is working properly. A series of flashes and pauses is a code for something wrong with your furnace. A breakdown of the flashing codes and their meanings should be located on the inner front panel of your furnace. An error code is usually a problem which requires a qualified heat tech to repair.


What is the cost to replace a Trane furnace transformer?

If you have the part number, many Trane furnace transformers can be purchased from online HVAC suppliers. The cost of a transformer should be around $20. You could also contact a licensed heating tech who can make sure you get the correct transformer and install it for you.


My Trane XR80 furnace is blowing cool air


On 2015-11-18 Eric wrote:

On page 8 of the owner’s manual there is a troubleshooting chart on common issues with the furnace. On the chart it states:

No Heat — Vent motor is running

Possible cause – Restricted or plugged furnace condensate drain

This is the solution they provide

    1. Remove drain clamps to condensate trap and drain pan outlet
    2. Flush or clean drain blockage
    3. Reinstall clamps

If you’re still having issues with the furnace or this is not the trouble you’re having, calling a licensed contractor would be a wise choice.

This furnace should be flashing an LED error code which can help you diagnose the problem. A few possible causes of a furnace blowing cold air are a dirty filter, a problem with the capacitor, a plugged air intake or a problem with the blower motor. Having a licensed tech troubleshoot and fix your furnace might be a good idea and help prevent further damage.
