Heaters aren't exactly silent machines, but they shouldn't be making enough noise for concern either. Knowing what different sounds might mean can help you get the problem solved quicker, so we've put together a list of common noises your heater might make:
- Groaning: This is likely to be caused by the motor bearings being worn down. A way to repair it is lubricating on the bearings and it might fix this if the damage hasn’t gone too far. Otherwise, the bearings will need replacement before the motor is damaged.
- Rumbling: If the sound is coming from the furnace cabinet, it means that the gas burners are dirty and you fix it by cleaning the burners.
- Clanking or Squealing: it can be caused by a loose blower motor fan belt and it can be repaired by tightening the belt, if it got cracked or dented you will need a replacement. this repair should be done soon to prevent a loose belt from causing damage to other components. Loud rattling: This is more likely caused by a crack in the heat exchanger. this particular issue needs the care of a professional because of the danger of the carbon monoxide leak.
