Furnace Not Heating? Here Is Why

There are all sorts of problems that can crop up with furnaces during the winter. The added wear and tear from operating on a daily basis tends to make it much more likely for various parts of the system to start breaking down. One of the most obvious problems that can crop up with your furnace is a complete lack of heat. Let’s take a look at some of the possible explanations for this issue.

Broken Air Handler

The air handler is the part of the furnace responsible for circulating heated air throughout the house. Without the air handler, all of the heat the furnace produces would simply stay in the furnace. The air handler motor uses oiled bearings to cope with the friction created during operation. These bearings eventually wear down, causing the friction on the system to increase and creating a loud grinding sound while the furnace is running. If the bearings aren’t replaced in time, the air handler motor will overheat and break down. If there doesn’t seem to be any air blowing at all while your furnace is on, this might be the reason.

Failed Ignition Device

Most furnaces are gas furnaces, which means that they use a burner assembly to combust natural gas and create heat. In order for the burner assembly to ignite, it needs an initial heat source from a pilot light. This can be a standing gas flame, a heating element, or an intermittent electrode that causes a spark. Regardless of the method, if this ignition device breaks down the furnace won’t be able to start burning natural gas and thus will be unable to operate. If your furnace doesn’t seem to be turning on, it may be that the ignition device needs to be repaired or replaced.
