A Trane furnace shows the owner that there is an issue within the furnace by using a red blinking light. The number and type of blinks indicate the problem. If the red light on a Trane furnace is blinking slowly, there is no problem with the furnace, but if it flashes quickly, it means there is no heat. If the light stays on, the furnace needs a new integrated furnace controller.
If the light flashes two times, the furnace is indicating a system lockout. Three flashes from a Trane furnace indicates a draft pressure error, which means there could be a venting issue, inducer problems or pressure switch problem.
If there are four flashes, the furnace is indicating an open temperature limit circuit, and if there are five flashes, the system is sensing a flame, but no flame should be found. If there are six flashes from a Trane furnace, it indicates the volt AC power is reversed, there is poor grounding or the system voltage too low.

Came home to a cold house. Playing with the thermostat got the fans to do strange things, but the burners never lit. Enlisted the aid of a recommended repair company. Upshot: Main circuit board is dead, and the furnace is only 12 years old. Cause of failure? Must replace just about everything, but the firebox, burners, circulation fan, and outer housing this list is shorter than the must-replace list. That is approximately one-half the cost of completely replacing the furnace with another — more highly rated — brand furnace.
Oh… and the AC unit in the system went out last year. At least I cannot accuse them of false advertising. Nothing runs like a Trane. If you are in the market for an initially expensive, unreliable, excessively expensive to repair, moderately efficient home heating and cooling system, buy a Trane. If, on the other hand, you prefer reliability and repair-ability at a rational price, then, in my experience, you should look for a different brand. I replaced a year old furnace and had my ducts sealed.
My gas use has gone up every month since then, and it is not correlated to the weather. The furnace is also very loud.
On Monday, the replacement blower motor wa sold — but without the wiring harness. Really, wth?
Trane can go to hell.It all started on Tuesday morning when my wife heard a strange and loud noise from our furnace. She took a picture of the exhaust vent and texted me, asking if the steam coming from the vent was normal:.
The steam was normal, I said, but the noise concerned me. That night, when I got home from work, it was still happening. It was a clanking, rattling noise that was so loud that we could easily hear it when sitting upstairs in our living room watching TV. I went down to the basement and took this video up close:. I read a few articles online and one troubleshooter suggested changing the filter. I also powered down the furnace using the emergency electric cut-off switch, waited a few minutes, and then started it back up.
The noise was gone. Problem solved. Or so we thought…. On Saturday morning at a. By a. Downstairs, I found that the fan was still blowing, but that the blue flames inside the furance itself were missing:. I called my dad and asked for advice. He suggested looking for an indicator light, seeing if there was a pattern and, if there was, looking in the manual to see what it meant.
I found the light on the bottom panel of the furnace:. Our light was blinking 6 times:. I found a few articles online suggesting tips for how to remedy that.
One suggestion was that I check the incoming air vents for any obstructions. At that point, I realized that I needed to call an HVAC expert, but it was the Saturday after Christmas, so everyone was running on emergency rates and had little-to-no availability. After checking several reviews and calling around a bit, I finally got ahold of a guy who not only guaranteed that he could make it out that day, but also offered a bit of troubleshooting over the phone.
When I told him that the the rollout limit circuit was open, he suggested that I reset it. Although this can be very helpful, it can also be the source of a false positive — the rollout limit circuit itself can go bad. So, a good troubleshooting step was to reset it and see what happened.
I pressed the button on both to reset them and found that the one on the left was, in fact, open. It clicked when I pressed it. Nothing happened. When he arrived, the furnace started right up for him with no problem. But, before I could spend too much time feeling like an idiot, the furnace acted up — badly — and I learned that I had made the right call by being cautious.
He switched the furnace off right away then explained to me that the primary heat exchanger was busted.Trane makes gas and electric furnaces as well as air-conditioning equipment for central heating, vent and air-conditioning systems in the home.
One of the most common problems that occur on a Trane XR80 gas furnace is its failure to operate. When this happens, the thermostat display may read as active, but turning the heater on does nothing.
Flashing Green Light On Lennox Furnace
Open and close the door until the small flashing red light comes back on to indicate a sealed connection. When the display screen of the thermostat is blank or the unit has no power to it, double check the circuit breaker. Under modern building codes, a furnace must be on its own circuit. Gas furnaces use gas to heat the home but electricity to power the fan and the thermostat and to turn the ignitors on to light the gas.
Check the circuit breaker by first flipping it off — as tripped circuit breakers may not appear tripped by visual inspection — and turning it back on. All furnaces require at least a once-a-year inspection or maintenance to ensure adequate operation when you need it most. Part of this process involves removing, cleaning or replacing the air filters inside the cold air return. The cold air return may be a screen on the wall in your home or the filters may be just inside the blower part of the furnace.
Remove the screens and clean or replace them. Permanent, plastic-type filter screens can be cleaned, while the paper-framed ones require replacement. Check filters at least every 90 days while the furnace is being used.
Depending on your skill level, you may be able to replace the ignitor yourself, but replace it if you have experience, otherwise have a professional handle the repair. Igniters have a limited life, especially in furnaces that are used regularly.
You can expect to replace them at least once every three to five years depending on whether you live in a dry climate, sooner in humid environments.

It only takes a minute to sign up. I noticed my home gas furnace was turning on, I could hear it running, but it seemed the fan was not blowing the heat out of the heat duct vents SO I went downstairs to the furnace, and looked at the red blinking light on my American Standard Freedom 80 furnace, and it showed 4 blinking flashes then a pause, so I looked on the error chart on the front panel, and it said "Open high limit device.
Anyways, while I was there at the furnace, I figured I would jiggle the 2 electrical connections that connect to the fan housing. I just tried to get the metal on metal connection of the electrical connectors to seat slightly differently. I put the front panel back on, and the system fired up, and this time I could hear the fan running and blowing the hot air.
I went upstairs, and yes, the heat vents had blowing hot air. Anyways, in the days before this I had been smelling an odd "electrical burning" smell, like a smell I had smelled before when I had a motor burn out, in some other unrelated tool. I'm just guessing that this smell is related to the new problem with the furnace? The filter was replaced one month ago.
Ultimate Guide Trane Furnace Error Codes
Well, I was wondering if you could suggest some helpful hints and knowledge? I sure would appreciate being able to learn. Does "open high limit device" error code mean that the device is stuck open?
What do you think the "burning" smell is coming from? Which part would be affected in such a way as to cause this? A "high limit" switch protects the furnace against overheating and damage -- it's located in the output duct, or plenumof the furnace and turns the furnace off if things get too hot up there.
The usual cause of a high limit trip is inadequate airflow -- in your case, because an apparently faulty connection was causing the fan to not run.
If you continue to get the "electrical burning" smell after fixing the connections -- that's a sign the fan motor on your furnace is on the way out the door.
Generally, you'll need to have an HVAC service tech come in and swap it for a replacement. If you can access the other side of the connection, you can also use a voltmeter to measure the voltage drop across it -- anything more than a volt is cause for serious concern.
I had the same thing. I checked both limit switches with a meter and the primary limit switch was open, but closed once it cooled off. It would heat up, light for a few minutes but the blower never turned on.
