With falling temperatures, you’re probably getting ready to turn on the heat for the first time. You might notice a burnt odor when you fire up the system. Here are some reasons for the burning smell when you turn on your heater.
Dust on the Surface of the Furnace
The most likely culprit behind the scent is probably nothing more than a coating of dust on the surface of your furnace. Even the best of housekeepers aren’t likely to be dusting the furnace when it’s not being used. When the dust buildup burns off, you’re bound to notice a tell-tale odor.
Problems With the Electrical Wiring
A scent that may be cause for concern is an electrical smell coming from your furnace. It could mean that the electrical wiring has worn down or is damaged in some way. This could result in serious and dangerous problems like an overheated blower motor.
Object in the Vent
Another common problem that can cause an unpleasant odor is a small object that falls into a heating vent. If you notice the smell is only in one particular room, this could be your issue. Look inside the vent or reach your hand in if you’re able. It’s likely you’ll find the offending item.
Dirt Buildup in Filters or Vents
An essential part of furnace maintenance is checking to be sure the filter is clean. If yours hasn’t been changed since last winter, you’ll want to take care of that. Dust and debris in the filter, or even the air vents, can cause that odd smell. If you notice a musty scent, it’s likely that the dirt caused mold or mildew to grow in your system.
