Common Furnace Problems And What They Mean

Nothing is more frustrating than a broken furnace during a cold winter. If your furnace is acting up, then you probably want to know just how severe your problem is. Here are a couple of common furnace problems and what they actually mean:

What if your heater won't turn on at all?

In this case, your problem is likely with the power or settings.

  • You should start by looking at the easiest possible solution, which is the circuit breaker. In many cases, simply flipping a switch on the circuit breaker could restore power to part of your house. This isn't always the case, but if you recently had a power outage or if you overdrew power in part of your house, then there is a pretty good chance that your circuit breaker is the source of your problems.
  • If that doesn't help, then you should take a look at the settings on your thermostats, You've probably already taken a look at the central thermostat, but did you try to tinker with the settings on the actual heater? If the temperature is set too high or too low, then that might cause problems. Ultimately, you will need to check the manual or consult the manufacturer of your furnace to determine what settings are ideal and what might be causing the problem.
  • Finally, you should take a look at the power line to your furnace. Even if you have a gas furnace, it likely still uses electricity to start, at least if it is a modern unit. The power line might have damage, but if it doesn't, then you might need to take a look at the control board.

If your problem still has not been resolved, then you might have a more serious issue on your hands, such as a broken component of the furnace. It's a good idea to call a professional at this point if you don't feel comfortable or experienced enough to do serious maintenance on your heater.

What if your heater isn't operating at full power?

In this case, you might have a problem with a dirty furnace or a blockage in the ventilation. If the problem is spread throughout the entire building, then the problem likely lies closer to the furnace. If only a single room is affected, then there is probably a blockage in the ventilation ducts near that room. It's possible to perform a cursory cleaning of your furnace and ventilation system on your own, but you might need to hire professionals if you want an intensive cleaning of your vents or heater. You probably don't have the specialized equipment that is needed to thoroughly clean vents, such as extremely long vacuum attachments.
