Furnaces are essential to ensuring a comfortable home, especially when winter temperatures arrive. However, a furnace that isn’t working properly can be very inconvenient and even dangerous. If you notice an issue with your furnace, it is important to contact a professional right away. However, before you do so, you should understand some common furnace issues and how to fix them.
Your furnace isn’t heating your house
If your furnace isn’t turning on or producing any hot air, the first thing you should do is make sure the power switch is on. Also, check to see that the thermostat is set to “Heat.” Another cause of this problem could be a dirty or clogged filter, and it may also be caused by an improperly positioned blower fan or insufficient ductwork.
Your furnace cycles on and off frequently
Frequent cycling of your furnace can cause a number of problems, including a clogged filter, low airflow, or an over-sized or under-sized heat exchanger. Additionally, if the limit switch isn’t functioning properly, your furnace will keep cycling on and off. A professional will need to diagnose the problem and replace the limit switch.
Your furnace emits a foul odor
If you detect an unpleasant, burning odor when your furnace is operating, it’s likely time to call for repairs. The smell is a sign of a malfunctioning gas valve or a mechanical fault with the system. If you smell gas, shut off the furnace and open a window to vent the room.
The ignitor isn’t lighting
The ignitor is responsible for heating the gas so that it can be warmed by the burners. The ignitor is located in a sealed combustion chamber that is covered by an inspection window. To locate it, follow the gas piping from the main gas valve and look for a box with an inspection window and wires that are either green or red.
Your blower fan constantly runs
If your blower fan is constantly running, it may indicate a problem with the motor, run capacitor, or thermostat. In addition, this can be a sign of a clogged or broken blower, and it is important to have this problem resolved before the cold weather arrives.
Attempting to fix some of these issues yourself can be tricky, and it’s always best to leave any complex or dangerous repairs to professionals.
