I heard your Trane furnace blinking red light issue. I thought that if you solved it, you
could also help me out with mine. It is doing the same thing!
Yes, I managed to fix mine, but you have to first of all, go through a diagnosis process.
Oh, I see, can you tell me more about this?
First of all, I think you should unplug your furnace, turn the thermostat off, and wait
for around 5 minutes. Ensure all doors are in place before plugging it back in ,and turning
on the thermostat.
What temperature should I set it at?
You should set it higher than the temperature in your home. If this doesn't solve the problem,
find the reset switch and reset the unit (if you hear a click and the light goes and stays
out, your problem is fixed).
Wow, now that would be really good. I think it will save me a lot of trouble trying to
fix it on my own, and eventually looking for professional help if I cannot do it.
Indeed, but there are also cases when these tips won't help, in those cases you need to
educate yourself on the codes of your furnace.
The red LED will flash, giving you a certain error code.
So you're telling me that I have to count the number of flashes?
Yes, that’s right. So if the flash is continuously on, then you have to replace the IFC. If it's
continuously off, then you have to check the power.
What if I see 2 flashes?
Then there is a system lockout, which means the recycles and retries exceeded.
Lastly, four flashes means you have an open temperature limit circuit.
Five blinking lights mean you have a flame sensed, when no flame should be present.
While six of them may be a few different things going on.
Like what?
Well, either the system voltage is too low, you have poor grounding, or the 115 volt AC
power reversed.
This has been really helpful to me. Thank a lot for telling me all these things about
my Trane furnace blinking red light.
Hey, that’s what friends are for right?
