coleman furnace repair manual

One easy way to do this is to regularly replace your air filter. This ensures that vital components can function at their best for long-term success. Common Furnace Problems and Troubleshooting Before attempting any sort of repair, remember to shut off the power to your Coleman furnace completely. If it's still not heating correctly, you'll want to replace the fuse. 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. If this doesn't appear to work or you don't have a scale, replace the thermostat completely. 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. The board's relay that regulates how much voltage is sent to the blower motor is defective. The sensor has become either dirty or defective. If it's defective then replace the sensor altogether. If it's still an issue, check for proper gas flow. It could be leaky or slow closing. Therefore, if it has opened, then check to see if the inducer is operating properly or there is an issue with the primary heat exchanger. These issues typically occur when there’s a broken internal component. Online consumer reviews are a great place to start. From these, you can learn about local HVAC contractors, the types of services they perform, as well as their potential prices.

Sometimes those that use batteries will flash a low-battery symbol when they need a replacement. If on, turn off the breaker and check the fuse for the furnace. You’re looking to see whether it’s thrown to the “Off” position, or whether it’s in the middle. Flip it back and forth. If this does not do the trick, you have a problem with either the wiring in the circuit or the circuit breaker itself. If you have a digital multimeter the next steps are for you: One of the most common reasons to have a furnace not working is a clogged filter. It also happens to be the easiest maintenance chore. This most likely looks like a grate in a floor, ceiling or wall. Other filters reside in the furnace itself. If no light shines through, the filter needs changing. A dusty, dirty smell from the vents when the blower turns on is another good sign you should change your furnace filter. No air should be coming out. Check the direction your filter points. Filters are made to trap matter blown from one direction. Installing your filter upside-down can reduce its effectiveness. W hen your air filter is clogged, your air handler must work harder to compensate for the blockage of air flow. In addition to driving up your utility bill, the reduced air flow through your heating and cooling system can cause your heat exchanger to overheat and shut off too quickly. A furnace door safety switch prevents the fan and burner from coming on while the access panel is removed. The door must be in place for the switch to be activated and for the furnace to operate. Not only does a clean furnace function better, it looks better. Crowding your furnace can lead to unexpected fires, significant damage to your home and danger to your family and pets. Don’t take chances, give your furnace the room it needs to operate safely. While you may have removed any and all flammable items from the area, remember that dust and lint can build up and create a fire hazard.

It's a whole different issue if your furnace is working poorly or not working at all. Your best bet though, is to have a maintenance check list for your heating system to avoid the problem. Saving a few dollars is not worth the uncertainty or a dangerous event involving the furnace.) You might be surprised how many service calls are made without checking this! You may need to change the batteries on your thermostat. If your home's thermostat unit runs on batteries, be sure you are changing them at least once a year, or as needed. How is yours powered.

Cool air is sent by the blower into the heat exchanger and warmed before entering the plenum and then sent throughout your home by the supply ducts. Check to ensure that your thermostat is not set to “continuous fan”. The sounds may indicate a mechanical problem, airflow reductions or a clogged burner. If you can tell the noise is a result of the air running through the ductwork, one solution may be to insulate your ductwork to cut down on the noise. There may also be an issue with the belts or even the burner. Or the belt needs replacement. The motor bearings need repair.

An excess amount of dust and lint can also cause your filter to become clogged sooner than usual, requiring more frequent replacement. You will want to inspect your burners to make sure they are free from debris. If they are yellow, you probably have dirty burners. You can clean your burners with a vacuum cleaner; just make sure to turn the power and the gas off first. Another area you should clean with a vacuum cleaner is the region around the blower. Therefore, it's very important to check and clean the furnace burners before the start of the colder seasons. The burner assembly should be cleaned annually or replaced if the existing one is in poor condition. Keeping a furnace blower lubricated will extend the life of your furnace. Remove the bolts securing the blower motor to the furnace's main assembly with a wrench. Detach the bolts. Pull the motor from the housing. Blower motor should run better with the new oil. It should be oiled once a year and it shouldn't make any unusual noises when started. Which means when they go bad, or the temperature gets too high they open the circuit. Drafts or clogs in your heating system can result in your pilot light going out. Do not touch the heating element, but if it looks cracked or damaged, you'll need to replace the igniter. As with the pilot light, you can do damage to the system and your property if you skip steps or safety procedures during this task. As always, the first may be a dirty or worn-out air filter. If you haven’t replaced it within very recent memory, try doing so — it’s a quick and easy fix. There may be an issue with the blower motor and belts, both of which require the service of a professional. Make sure the blower is clear of any debris. Also, there should be a flashing light; green or red. If the light is green, it's okay; if red, call for service. And if there is no light, the furnace problem may be with the thermostat, the blower motor, the run capacitor, furnace control board or transformer.

As I said, we had a nasty snowstorm last night. It wasn't a lot of snow, but what came down was wet, heavy, and sticky. Of course, the wind was howling too; high winds are what defines a storm as a blizzard. I certainly understand that and agree: I leave most things to the pros. At 5:30, I hauled myself out of bed. The power had come on again, so I walked to the living room to turn up the thermostat. We keep the heat dialed way down overnight; it is programmed to turn back up at 6:00 AM, but I was up earlier as noted. I turned it up and the furnace did kick in. I went to the kitchen and snagged a yogurt from the fridge. I had barely got to the drawer where we keep the spoons when the electricity went off again.

Just a few moments later, it kicked in again and shortly after that I heard the furnace start up. I sat down at my computer and started some work. Perhaps a half hour later, the lights went out again. This time, they stayed out until just before my wife got up—possibly the chirping phone-setup message woke her up this time. We both sat down at our computers after eating a banana and a few nuts. A few hours later, my wife noticed that the house was getting cold. I got up to look at the thermostat and saw that it should have been calling for heat, but the furnace was not responding. I shut the thermostat off and turned it back on, dialed down the temperature and dialed it back up, but got no response from the furnace. I could hear the relays click in the thermostat, so I suspected it was not the culprit and moved on to look at the furnace itself. Troubleshooting the Switch The covers on these units are a pain to take off and put back on. I counted to ten, turned it back on, and was rewarded with the sound of the furnace kicking in. That's good, I thought, and went back to my work. Unfortunately, it was not good: after the long air purge cycle, which is designed to blow out any lingering explosive gases that might have found their way into the ducts, the furnace did not fire. Obviously I had a partially working furnace, but it did not want to fire. Neither furnace manufacturers nor home owners like furnaces that blow up, catch on fire, or leak poisonous gases. That's why the units have various safeguards built in, like the air purge before firing off. Many furnaces today have some sort of diagnostic indicator that can sometimes tell you what is wrong. For my furnace, it's a flashing green light and the cover of the control box helpfully tells you just what these lights mean. Google your furnace model if you don't find a chart inside the unit. One flash: Ignition lockout But, where is this flashing light.

Well, you can see it if you step to your right and look at the side of the control box. It's not particularly easy to see, but you do not have to remove anything else to see it. The peephole is just above the blue wires in the picture below. It was a faulty unit. I did not attempt to replace it myself, but I did let the service company know what they'd need to bring. In this case, they had the proper switch on their truck anyway, so it wouldn't have mattered, but of course it could have. In this case, the light was flashing four times. That means a limit switch was stuck open. I called the service company and told them. When he arrived, he showed me how to follow the diagram to find the switches. The diagram also shows the colors of the wires that go to these switches. The tech followed the colors and found that the lower switch was a small circular disk that had only the two wires coming into it. When we followed the gray and blue wires for the upper switch, we found something that had a button on it. Buttons like that are usually reset buttons, so he pushed it. Upper limit switch I then cycled the furnace circuit breaker again and this time the furnace fired off after its purge. That was a welcome sound. We let it run a bit, shut it off using the thermostat, waited a bit, and turned the thermostat up. The furnace worked again, so we were both satisfied that the issue was fixed. The next time this happens, of course, I will try resetting that switch before I call for service. While I had heating systems on my mind, I decided to change the batteries in my thermostat. It's easy to forget about these—they draw very little current, so the batteries can last for years. It's a good idea to replace them more often than that, though. As we use rechargeables, I just change them whenever something makes me think about the thermostat—that's often enough that I shouldn't ever have a problem. Batteries in thermostat Update Last winter we had frequent furnace problems.
