My Coleman Furnace is Not Heating

A Coleman furnace not heating is a remarkably common problem. This does not mean that the brand is of poor quality. Quite the contrary, in fact, Coleman units have a good Energy Star rating and are noted to have 20 plus years of longevity. However, a unit can stop heating for various reasons, several of which are fairly simple to fix on your own.

If the pilot light keeps going out, the furnace will not heat your home. A device called the thermocouple is usually the cause of this heating issue. The thermocouple is a sensor. It sits inside of a steel sleeve located in front of the pilot light.

It must be heated by the pilot light before it can send an electrical charge to the furnace, stopping the gas valve from closing. The pilot light flame should be a minimum of two inches long. You might need to adjust it to meet this size. It should then heat the thermocouple. If the light continues to go out, the thermocouple may need to be replaced. Replacing it can stop the gas valve from closing, thereby allowing you unit to heat again.

A Coleman furnace not heating properly can also be due to a buildup of gunk in the air filters stopping warm air from circulating. Check the filters and clean them if you notice a buildup. You can use a small vacuum to remove dirt.

Rinse the filters with water and let them dry completely before replacing them. If this does not solve the issue, there might be an issue inside the unit itself.

Locate and open the access panel of your unit. You’re looking for the blower motor. It should be at the base of your unit. You will see a belt connected to the fan assembly. Check to ensure it is tightly in place, adjust it if needed. If the belt is frayed, you’ll need to replace it. If this does not solve the issue, then chances are the burners are dirty.

If the cause of your Coleman furnace not heating is dirty burners, a service technician will need to be dispatched. Only a qualified tech can successfully and safely clean the burners. If your warranty is still valid, this fix should be covered.

Coleman Furnace Problems

Every furnace on the market comes with its own set of possible issues. If you own a Coleman unit, then you are probably interested in learning about some of the common Coleman furnace problems experienced by customers. Most of their models experience issues that stem from improper installation or lack of needed maintenance.

If you are purchasing a unit, it is imperative to hire a qualified installation technician. Coleman has local authorized dealers in most states. Contacting a local dealer for an installation is recommended, and it shouldn’t cost much more than hiring a contractor.

If your unit came with the home you now own, you can contact your local dealer and ask for a qualified technician to come check the unit. They can usually spot whether or not it has been properly installed, and make any needed changes if the installation was not up to par.

Common Coleman furnace problems include the blower not working. The blower can stop working for several reasons—the most common being a lack of proper preventative maintenance. The manufacturer recommends lubricating the axle, cleaning the blades, and checking to ensure the motor is not being overloaded. A blower can suddenly stop working because the axle runs out of lubrication. The fan belt should also be regularly adjusted to ensure it averts no more than an inch when pressed.

Another common issue is the thermostat. It is extremely rare for a thermostat to fail outright. However, it is very common for a it to degrade over time. Every thermostat is comprised of mechanical parts that can stick and lose their calibration over the years. The older the unit, the more common it is for a thermostat to be off.

You can keep it in good working order by customarily making a minor adjust. Use a wrench to adjust the nut on the back of the mercury switch. Adjust it until the unit turns on. Then, use a room thermometer to set the thermostat to the proper temperature.

A great majority of Coleman furnace problems are easily fixable and preventable. Preventative maintenance is important. If your unit is covered under warranty, you can have it regularly serviced at little to no cost to avoid problems.

My Coleman Furnace is Not Working

Years ago when an important necessity—like a gas powered furnace—decided to stop working, folks attributed it to little mythical creatures called Gremlins.

Today we know better than to blame the case of a Coleman furnace not working on little mischief-causing mythical creatures, but the problem still remains. What do you do on that one snowy day when your furnace decides to an extended lunch break without warning?

The very first step to take is checking the fuse box and the circuit breaker. Make sure that the unit is indeed receiving power. If your power supply checks out, take a look at the power switch.

Coleman units have a power switch that has an “On” and “Off” position. For peace of mind, make sure the switch it flipped to “On.” If it is, then on to the next troubleshooting step:

In the case of a Coleman furnace not working, it is possible that the motor has overheated. Typically this does not happen. However, if your unit has been running for several hours it is possible. The best course of action is to let the unit sit for about half an hour.

Start it again after this cool down period. If the unit does not start, check the pilot light. If the pilot light is not burning, re-light it after ensuring there are no gas fumes present. If you smell gas, avoid any further troubleshooting and contact local authorities as you leave the area.

If no gas fumes exist and re-lighting the pilot light does not work, next check the gas valve. It should be completely over. If not, open it completely. This covers the basics of troubleshooting a furnace that is not working. If these steps do not remedy the unit, it is time to contact a local dealer and ask for a qualified technician to come investigate the problem.

In good news, most consumers are happy to call their local dealer. Local dealers have quick response times, and in most causes their warranty covers all of the work. While your Coleman furnace not working is an inconvenience, it is a fixable problem that even a Do It Yourselfer can have a stab at handling.

Coleman Furnace Diagnostic Codes

Coleman furnace diagnostic codes can be intimidating if you are not comfortable diagnosing your own unit. Most units have a diagnostic light that can be found behind a single panel. The panel can be removed by taking out one screw. The panel itself will have electrical hazard warnings on it, which can be intimidating if you are not used to working on electronics. Be cautious and take your time.

Once the cover has been removed you will see a single green LED light. The light will blink to indicate a problem. Different problems are indicated by a unique number of blinks. Many customers can reference their user manuals for specifics about what each sequence of blinks means. Simply count the number of blinks and reference your manual. Some customers who either lost or do not have a manual have called their local dealer to find out what a specific code means.

A common sequence is the green light blinking three times in a row. According to Coleman furnace diagnostic codes, this means the combustion air switch failed to close—a common issue that can stop the unit from working.

In many newer Coleman units you will see both a green and red light together. Do not confuse this with the single green light that indicates a diagnostic code! The green and red light should be labeled as “Blend-Air.” The function of this feature is to bring in fresh air.

If a problem crops up here, the red light will flash and is often accompanied by a beep. If you see the red light flashing or hear beeping, you can still safely run your unit. Do contact a technician to come check out the unit. There should be a switch nearby the red light to shut off the beeping so it does not drive you bonkers in the meantime.

There are very rare instances where Coleman furnace diagnostic codes mean a life threatening problem exists. However, if you ever smell gas around your furnace when it has stopped working or a diagnostic code is blinking, do not attempt to troubleshoot the problem yourself. Leave the area, contract local authorities, and contact a qualified technician for help.

Coleman Furnaces for Mobile Homes

A Coleman furnace for mobile homes— is quality a concern?

For mobile home owners, purchasing important home appliances like a furnace or air conditioning unit is a challenge. It can be tough to find a brand that installs in a mobile home with the same standards as a stationary home. Although we don’t like to admit to it, our society has a preset stereotype about modular homes. How do you combat that when furnace shopping?

Coleman offers an electric furnace that is very popular to mobile home owners. The price is reasonable and affordable. The units come with a written limited warranty that protects all parts and pieces of the unit. The hard part, according to consumers, is hiring a qualified installer and making sure the warranty is in working order.

Purchasing a Coleman furnace for mobile homes is best done through a local affiliated dealer. Seasoned consumers will tell you that not all dealers are equal. Some take greater pride in their work than others. Track down a dealer with experience installing units in mobile homes. Experience can make all the difference in the world, and proper installation is vital to avoiding problems down the road.

Take time to read, understand, and detail the warranty. Many mobile home consumers say that “normal use and service during the applicable warranty period” is sometimes applied differently to a mobile home. They said by having the dealer detail exact terms in this regard they were able to have a fully functional warranty that was easy to use when needed.

Coleman units manufactured for modular homes in the last 10 years do not have a high customer satisfaction rating. Consumers who did not push setting the exact terms of their warranty often end up paying for service calls and repairs, which can become increasingly expensive.

About 30% of consumers owning a Coleman furnace for mobile homes would recommend it. Almost all of them say proper installation is absolutely vital. Finding a dependable installer is best done through a local dealer. Make sure whoever you choose to install offers a guarantee of a proper installation.
