Three Easy Steps to Fix Your Concord Furnace Code and Get You Warm Again!
If you have a Concord furnace, then you know they are not the most user-friendly units to own. That’s why many homeowners find themselves locked and frozen out of their furnaces more often than they’d like. If your furnace is displaying an error code, it’s probably because there is a problem with the heat exchanger or condenser fan circuit. Once you have pinpointed exactly which component is causing your furnace to give you error codes, fixing your unit will be a snap. Depending on what error code you are getting, there may be slightly different troubleshooting steps involved in getting it running again. This article goes over the three most common codes that appear on these units and how to fix them. Read on for insight into fixing your broken furnace!
Code 3: Fan Circuit Malfunction
This fan circuit malfunction code can be a tricky one because it doesn’t indicate that there is anything wrong with the fan itself. Instead, the problem lies with the control board, the wiring, or the motor that operates the fan. If you have this code, you will have to test the voltage going to the motor to make sure it is receiving power. If it isn’t, there may be a problem with the furnace circuit board or the wiring leading to it. If you have a volt/ohmmeter, plug it into the wires leading to the motor to make sure it is receiving power. If the motor is not receiving power, it will not spin at all, which will prevent the furnace from blowing out any heat. No heat means that the furnace is not capable of heating your home. If your fan is not receiving power, your furnace will not be capable of pushing warm air through your duct system. If you have a code 3 and your fan is not receiving power, you will have to replace the furnace circuit board.
Code 6: Condenser Fan Circuit Malfunction
If you have this code on your furnace, the problem lies with the motor that blows warm air out of the furnace and into your home. To begin troubleshooting, you will want to remove the cover of the furnace to inspect the motor. If you find any damage to the motor, you will have to replace it. Sometimes the motor is simply dirty inside and needs to be cleaned out. The motor may have become clogged with dust and dirt, causing it to overheat and trip the diagnostic circuit. If you find that the motor is simply dirty and needs to be cleaned, you can remove it and use compressed air to blow out the inside. You will want to use caution when cleaning out the motor, as it can be extremely hot when the furnace is running. You don’t want to burn yourself on the motor. If the motor is not damaged, you can attempt to clean it by removing it from the furnace. Once it is removed, you can use compressed air to blow out any dust and dirt that may be clogging the motor. If you find that the motor is clogged with dust and dirt, you may need to replace it. Replacing the motor is one of the easiest and least expensive repairs you can make on your furnace.
Code 11: Heater Condenser Coil Malfunction
If you have this code, the problem lies with the heater on the back of the furnace. To troubleshoot this code, you will want to remove the cover on the back of the furnace and inspect the heater. If you find that the heater is dirty inside and needs to be cleaned, you can use compressed air to blow out the inside of the heater. If the heater is simply dirty, it can be cleaned using compressed air. If you find that the heater is broken, you will have to replace it. Replacing the heater is a quick and inexpensive repair and can be done in as little as 15 minutes. The heater is one of the most common parts to break on a Concord furnace, so you will want to watch it. If you find your heater is broken, you will want to replace it as soon as possible. Leaving a broken heater on your furnace will likely cause other components in the furnace to break, which can lead to a very expensive repair.
Code 17: Evaporator Coil Short Circuit
If your furnace is displaying a short circuit error, you will need to replace the evaporator coil. The evaporator coil is the part of the furnace that heats up and sucks air into the furnace. When air is sucked into the furnace, it travels through the coil, which warms it up and sends it throughout your home. If the coil is shorted out, it will not be able to heat the air properly, which will prevent your furnace from blowing warm air. Replacing the coil is a simple, inexpensive repair that can be done in as little as 15 minutes. The evaporator coil is one of the most common parts to break on a Concord furnace, so you will want to watch it. If you find your evaporator coil is broken, you will want to replace it as soon as possible.
A broken furnace is a nuisance to deal with, but it doesn’t have to be a nightmare, either. This article has gone over the three most common errors that appear on Concord furnaces, as well as how to fix them. Use this information to solve your furnace problem and get yourself warm and toasty again. With a little effort and a few common tools, you can solve your furnace problem and get back to enjoying the comforts of home again. Now you know what these codes mean and how to fix them, an uncooperative furnace will no longer be a problem. Get to work and get your heat back on!
