An electric furnace is a simple device that uses heating elements to warm air for distribution. If you're not getting heat, first check the unit's breaker or fuse panel. (click to enlarge)

An electric furnace uses electrical energy to warm air for distribution throughout the home. An electric forced-air heating (EFA) system includes a heating element, comfort controls, and forced-air distribution systems, each covered in other guides. The source of power, electricity, runs through the Electrical Service Panel.

If the furnace won't run, check the electrical service panel for a blown fuse or tripped breaker. Also make sure the power switch on or near the furnace is turned on. Check the unit for a reset button and try it. Some units have a built-in breaker or fuse panel.

If there is not enough heat, raise the thermostat setting five degrees to see if it turns the unit on. If the unit still does not generate enough heat, check the comfort controls. Clean or replace a dirty filter, clean the blower assembly, and make sure that all registers are open and not blocked.

If the furnace turns on and off repeatedly (cycles), clean or replace the filter; and clean the blower assembly.

If the furnace is noisy, make sure access panels are mounted and fastened securely; spray squeaking belts with fan-belt dressing and replace worn or damaged belts; adjust the blower belt; lubricate Motor and blower oil ports.

If the element does not heat, refer to heating element for guidance.

If some rooms are too cool and others too warm, the distribution system may require balancing.
