  1. Dirty Ductwork – This is a common problem and one that many people do not think about. If there is a buildup of dust and debris in the ductwork, it will make it harder for the heater to work. You will not get the full effect of it because it is too dirty. You can have it cleaned by an HVAC technician and it should be done on a regular basis.
  • Change Your Filters – You should change your filters on a regular basis, as well. Dirty filters will also prevent your heater from working correctly. You can do this on your own or you could hire a professional to do it for you. It is an easy job that almost anyone can do, though.
  • Starting Mechanism – You might also need to fix the starting mechanism. In older heaters, this might be the pilot light. Newer heaters will usually have an electrical ignition: Both can fail, and you will need to have a technician repair it for you.
  • Blower Components – There are a few blower components that will need to be checked. You might need to replace the blower bearings that would cause the blower to stop working. You might also need to replace the blower belt. You could also have a damaged blower capacitor.
  • Heat Exchanger – This is a part that few people have heard of, but all are grateful for. The heat exchanger is a group of coils of heated tubes. The heater will push air through the heated tubes that will then warm the air and then push that warm air through your home. You will need regular furnace maintenance to make sure that these stay in good condition.

  • Limit Switch – The limit switch is a part of your heater that keeps you safe and makes sure that your heater is working properly. It will let you know when there is heat in the furnace, telling the furnace when to turn on and off. It can also tell you when the furnace is getting dangerously hot. If it detects too much heat, it will turn off.
  • Flame Sensor – This is another part that needs to be maintained by a professional. It is on the surface of the high-limit switch. The flame sensor will let you know that the flame is present. If it is not present, it will shut your furnace down.
  • Thermostat Repair – Sometimes, the problem with your furnace is not your furnace at all. It is the thermostat. The thermostat tells you about the temperature in your home. It will turn your heater on when it gets too cold and will turn off when your home gets to the right temperature. If it is not working properly, your heater will not either.
  • Check for a Tripped Circuit Breaker – This is a simple issue to check and fix. Your circuit breakers will sometimes trip and will need to be fixed. This usually happens when you have a power surge. Learn more about that here. If it keeps happening, you might need to have the problem looked at by a professional.
  1. Noises – Sometimes you will hear unusual noises from your heater. They can be thinking noises, clunking, or squealing. When this happens, it is a clever idea to call a technician out to see what is going on. You might find that it is something serious that needs to be fixed right away.
  1. Gas Odors or Leaks – If you smell gas odors or suspect a gas leak, you need to get your family out of the home first. Then you need to call a technician and the gas company to report what you smell. This might be a metallic odor that you smell and needs to be taken very seriously. You should turn off all the gas and open all your windows while you are waiting for the technician and gas company.
