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. 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.
This caused it to overheat so the induction blower turned on and stayed on to cool it off. This ind blower would not turn off until I unplugged it. An hvac guy I know said to buy American because it will last longer. The capacitor is attached to the blower housing. Watch videos on how to change it.When lit, this red light, also called a lockout light, indicates that a safety mechanism on your furnace has caused a shutdown because it has detected a problem or recognized a fault.
Note: Not all furnaces have this red light. Some have a red reset button that does not light up. The most common trigger for a shutdown is the absence of a flame when the burner kicks on, but there are many other causes, or it may just be a fluke. If your furnace has a digital display that provides a fault code, you can easily check the fault code to diagnose the problem.
Make sure you have oil in your tank. Make sure the oil valve is open. A closed oil valve prevents oil from getting to the burner and will prevent the burner from firing. When no flame is detected, the furnace will shut down.
After checking your oil supply and oil valve, press the reset button. Press and release the reset button to see if the furnace will fire. If it does, and this happens only once, it was probably a fluke. Call a professional, as this is a sign of a more serious problem.

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.
Seven flashes from the system show that there is a gas valve circuit error, and eight flashes means the low flame sense signal has gone off. When there are nine flashes, the system is indicating some type of grounding problem.

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.
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.

Results 1 to 12 of Thread: Trane xv95 red light flashes 6 times? Thread Tools Show Printable Version. Trane xv95 red light flashes 6 times? I bough this house this year, it was build in The humidifier was not working, then I found out the 24V transformer was dead due to the wrong wire which made it short circuit.
So I bough a new transformer and put it on as the original wire connected. The problem starts. I tried to measure the voltage on the board then found out that the N-line has V voltage. So I checked the wire map details then found out the wire was connected wrong which originally the HUM hot was connected to Line-N wire together. Here is a question why it works originally, even I put the bad transformer back it won't work any more.
Then I connected the wire as the circuit map which Line-N connected with power supplies N line and transformer's N-line. The HUM hot comes from main board connect to transformer's hot line. From this point the mainboard get power but it won't fire up when there is heat calls. The red light flashes 6 times which on the manual says " V AC power revers or igitor fault". Could anyone help to give some clue here?
What Does the Blinking Red Light on My Furnace Mean?
Thanks, Robin. Originally Posted by ziyunxiao. The red light flashes 6 times which on the manual says " V AC power revers or igiter fault". Originally Posted by MM 7. This is above what the rules will allow as far as advice.
The fault code has made it clear where the problem is. You are running the risk of damaging the electronics in the unit so I suggest you turn the power off to the unit and call for service from a local HVAC firm. Tell the tech that comes out about the fault code and what you have replace or changed up to this point. Regards, Heaterman. If you are that leery of getting a poor job from a professional, just keep doing what you're doing.
You should be able to fix it on your own sooner or later. Originally Posted by 2old2rock.
