It is shocking to realize that your heater is broken when you wake up in a cold house! And you’ll ask yourself, ““why does heater not working in my house?” Numerous factors can contribute to a heater’s dysfunction.
Sometimes the solution is as easy as changing the thermostat’s batteries. In other cases, it can be a crucial component that keeps your heating and air conditioning system operating that just wore out at the wrong time, or perhaps you forgot to do the annual maintenance on your heater. This happens.
Reasons Why Heater Not Working In My House
#1: Air Duct Leaks
Leaky ducts may be the cause of the frigid air your heater is emitting. Cool air may enter through the vents as a result of heated air escaping through ductwork leaks before it reaches your rooms.
Damage, old ducts, or inadequate insulation might all result in a leak. You can increase the effectiveness of your heating system and guarantee that warm air gets to its destination by checking for and fixing any leaks in your ductwork.
#2: Broken Heat Exchanger
Before they can safely exit the furnace, flammable gases must first encounter the ignition source inside the heat exchanger. But if this part cracks, hot gases and potentially dangerous pollutants could enter the system, travel through your home, and affect the quality of the air within. Instead of warm air blowing through the room, chilly air will instead because a trigger in the system will cut off the ignition source.
#3: Clogged Air Filter
Clogged air filters are among the most common problems with heaters. Your filter is probably blocked if your heater is unable to blow anything or at least does not release hot air. As dirt accumulates in filters, they inevitably become blocked. Your heater will shut off as a result of this accumulation since it reduces the quantity of airflow throughout the system. You should replace your filters roughly every 90 days to prevent clogs. It’s a good idea to have your system tested in addition to updating your filter.
#4: Faulty Furnace Control Panel
You might need to examine the control panel of your heater if none of these easy repairs resolve the issue of cold air blowing. All of the heater’s operations are controlled by the heater control panel, also known as the furnace control panel. It is important to periodically check for any errors or faults that may have happened.
#5: The Gas Supply Is Turned Off
If you turn off the gas line supply, the heater may blast chilly air instead of warm. Most often, this occurs when the heater breaks due to an issue. For instance, your furnace may have had a malfunctioning gas valve, a broken gas supply pipe, or another issue. For safety reasons, the person who installed your heater would have shut off the gas supply while repairing or replacing it when this occurred.
#6: Improper Wiring
If any of your cables are ragged, worn, or carelessly attached, the thermostat may lose its connection to the heating system. If you think your wiring is defective, call an HVAC professional.
#7: Lack Of Maintenance
The likelihood is that a dirty furnace is the cause of your heater’s failure to start. Your furnace may not function properly if there is dirt on your flamer sensor or blower motor. Too much dirt in the blower motor will prevent it from sending adequate cool air to the heat exchanger, which can cause equipment failure.
Because of the soot and rust, an unclean flame sensor will not be able to “sense” the flame. The sensor will immediately turn off the furnace to stop a gas leak if it is unable to detect the fire through the soil.
#8: Malfunctioning Furnace Air Filter
A malfunctioning furnace air filter is also a possible cause of your heater’s cold air emission. The heater may require more energy to make up for the lack of internal airflow if the air filter is clogged or unclean.
Regularly cleaning or replacing your furnace filter will resolve this problem and prevent the need for heater repair services during the winter.
#9: Overheated Furnace
Overheating is another possible cause of cold air coming from your heater. In order to protect the furnace blower motor from harm, an emergency shutdown may be triggered when a furnace overheats and runs at a higher capacity than usual. In this situation, the heater might not work well for a few hours.
#10: The Pilot Light is Gone Out
Because there won’t be any ignition in the burners, your heater won’t be able to operate properly if the pilot light has gone out. One easy way to determine whether your heater is producing chilly air is to check to see if your pilot lights are on. This needs to be monitored because a heater without a pilot light won’t function and could possibly start a fire!
#11: Thermostat Issues
One possible cause of your heater’s dysfunction is that the signal from your thermostat isn’t getting to the furnace. Everything from something as minor as dead batteries to something more than serious like an issue with the thermostat that needs to be replaced can be the cause of the malfunctioning.
Look for troubleshooting information on the manufacturer’s website before having your thermostat replaced. It might be time to hire a professional to investigate the cause of your heater’s malfunction if none of the troubleshooting methods resolve the issue.
Conclusion
“Why does heater not working in my house?” is a question that many homeowners are wondering. Thermostat problems, poor maintenance, clogged air filters, malfunctioning wiring, malfunctioning furnace air filters, turned off the gas supply, a pilot light not working, and problems with the furnace control panel are some of the reasons why a heater may not be working properly.
While blocked air filters might force the heater to work extra, thermostat problems can result in equipment failure. Checking the control panel can be necessary if these problems don’t resolve the issue. Cracked heat exchangers, leaking air ducts, and overheated furnaces can also be problems. Larger issues can be avoided with routine maintenance.
