Coleman Furnace Troubleshooting
If you're looking for help fixing your Coleman Furnace, look no further! Our comprehensive Coleman Furnace Troubleshooting guide will explain common issues, provide tips, and show you how to read your model's error codes.
Either the circuit breaker has shorted or the unit's fuse has blown. Reset the circuit breaker associated with your Coleman furnace. If it's still not heating correctly, you'll want to replace the fuse.
The igniter has cracked or become defective. Locate the igniter within your Coleman furnace and inspect the part for cracks. If it's damaged then you'll have to replace the part. Otherwise, test it with a multimeter for continuity to see if it's defective.
Your thermostat might be calibrated improperly and as a result, is adjusting incorrectly. Check to see if your thermostat has an adjustable calibration scale, if so then use this to adjust the heat anticipator. If this doesn't appear to work or you don't have a scale, replace the thermostat completely.
Not blowing hot air?
The blower motor in your Coleman furnace is either burnt out or it's connecting belt has broken. You'll have to inspect the motor to see if power is reaching it. If it does but the motor continues to function incorrectly, then the blower motor has failed. However, if the motor continues to run, but the air still isn't moving, then the connecting belt has broken. Depending on the situation, you'll have to replace the motor or the belt.
Blowing too much air?
The control board is experiencing difficulty. The board's relay that regulates how much voltage is sent to the blower motor is defective. You will have to replace the control board.
The contact on your thermostat responsible for controlling the blower motor is defective. Use a multimeter to check for continuity, if the thermostat isn't working properly then replace it.
Starting and then stopping shortly after?
The flame sensor used to detect whether or not a flame is present requires attention. The sensor has become either dirty or defective. Use a fine abrasive pad to clean the sensor if it appears to be dirty. If it's defective then replace the sensor altogether.

Our furnace and air conditioner are both Coleman, and they have lasted for ten years. The AC always needs replacement although this is not part of the furnace and we cannot complain about this. The high energy conversion rate as a result of the AFUE high levels makes it the best for me. I have not had any replacements or repairs so far, and I hope I will not have any problems with my furnace. The price is manageable, and I would recommend this to anyone who needs a gas furnace that is not too pricey and works efficiently.
Coleman furnaces are some of the best high-efficiency furnaces so no matter what your budget is, you can probably find room for a high-efficiency or ENERGY STAR certified upgrade. Coleman has a decent selection of heating systems that includes basic single-stage models, two-stage furnaces, and more advanced systems with modulating burners. All Coleman furnaces are backed by excellent warranties that cover parts, heat exchangers, and even labour.
I agree that the installation is the main point when it comes to gas furnaces. I am nothing but satisfied by this brand of Coleman. My previous gas furnace kept on leaking and made my house messy, and I had had to clean often. I always called the technician to do repairs who later on recommended to me the Coleman unit. It’s highly efficient without too much cost of the gas bill. It was also affordable, and the installation was easy.
Coleman offers four different product lines of gas furnaces, namely the Echelon Series, LX Series, Comforteer Series and Coleman Light Commercial Series. Very few of the models are certified by Energy Star.
Being HVAC technician, I have installed this unit on some my clients, and all I can stress is that it is a good unit as long as the installation process is performed by someone who perfectly knows when he is doing and not just anyone. The mistake that many users do is to install a unit without the help of an expert, this leads to poor installation, and the unit starts having problems too early, and some do not even end. Proper installation of any unit is essential if you want your furnace to last long enough. The only bad thing I had with this unit is the unit being a little noisy; the manufacturer should do something about the noise. The price is friendly, and I would recommend this to my clients at any given time.
