Carrier furnace, it is a good idea to reset it first and see if this would revert the system to normal. Issues like ignition lockout are usually resolved by resetting the Carrier furnace. Locate your thermostat and turn it down to prevent it from triggering the need for heat from the furnace. Turn off the breaker switch that supplies power to your furnace, or you can unplug the furnace. Turn the breaker switch back on or plug your furnace back in. Although the steps to reset your Carrier furnace can be simple to follow, there are important safety precautions that you need to know to ensure that you do not get injured while troubleshooting your Carrier furnace. Additionally, there are common issues below that you check in case resetting your Carrier furnace did not resolve your issue. Troubleshooting or repairing a furnace can be a dangerous activity if safety precautions are not properly followed. Performing repairs while the Carrier furnace is still connected to electrical and gas supplies can result in serious injuries, property damage, or even death. Turn the electricity and gas back on only when you are done with the repairs and troubleshooting. What causes a flame rollout switch to trip? Whenever the flames reach areas of the furnace where they should not go, the temperature inside the furnace will start to rise. Flame rollout switches are sensitive to changes in temperature inside the furnace cabinet. It detects unusually high temperatures around the burners and will get tripped if these temperatures get too high. As a safety precaution, the furnace will stop burning once this switch is tripped. If your furnace keeps turning off after a certain period, this could be the culprit. There are several possible causes behind this issue. If the exhaust vent is clogged, the airflow will be limited. Limited airflow can cause the flames to escape. A similar situation will occur if the heat exchanger is clogged because the flow of air will be restricted. Flame rollout can also happen in this situation. Heat exchanger clogging is often caused by corrosion or soot buildup. Soot comes from gas molecules that do not combust completely. Over time, this can form and accumulate inside. A small amount is normal for any furnace. However, too much soot buildup could become an issue for the furnace. A clogged heat exchanger makes your furnace inefficient. It can even prevent your furnace from functioning at all. It is recommended to hire professional HVAC personnel to clean the heat exchanger. A cracked heat exchanger becomes ineffective because it loses the ability to create sufficient pressure. Another sign of a possible cracked heat exchanger is when your carbon monoxide alarm keeps going off. A damaged heat exchanger can cause combustion gases to escape and seep into the rest of your house. This is dangerous because combustion gases like carbon monoxide are toxic. A professional should verify the possibility of a cracked heat exchanger as soon as possible due to the serious health risks involved. Low gas pressure can also cause flame rollout. A low gas pressure causes the flames in the furnace to roll out instead of going into the heat exchanger. This is usually caused by dirty burners. When the burners get clogged, the gas pressure will drop because the passageway of the gas is not enough to produce the right amount of gas pressure. What to do when a furnace is not heating? The reasons below are among the most common why a furnace is not heating. A faulty flame igniter can prevent a furnace from heating. A cracked igniter can prevent it from generating the required amount of heat to ignite the gases inside the furnace. Moreover, if there is no continuous electrical flow through the igniter, then it could prevent the furnace gases from igniting as well. Replacing the igniter will solve this issue.

This can be cleaned with nylon cleaning pads. If it fails to sense fire after cleaning, it will have to be replaced. Click here to find this replacement flame sensor from Amazon. This motor sucks air for the heat exchanger. A switch that is sensitive to changes in air pressure watches out for any changes. It will close another switch that tells the control board of sufficient airflow if there is enough change in the pressure. Once this happens, the furnace will shut off automatically in a few minutes. Have a professional replace a faulty draft inducer motor. Control boards regulate the electrical supply for the different components of a furnace. If the control board fails, the ignition system will not receive power for the furnace to produce heat. A defective control board needs to be replaced. The wall thermostat controls the temperature of a heating system and sends power when more heat is needed. If the electrical contact in the thermostat is d filexlib.
