Electric furnace heaters should regularly inspected for any signs of overheating. When the electric starts acting up enough that you know something is wrong, several causes could be behind it. Don’t immediately assume that the something that is wrong is a major problem that is going to cost a bunch to repair. Regular maintenance of your electric heater can keep the potential for maximum output of cash to a repair professional very low.
Examine the blower belt for signs of tension and wear at least twice during the heating season. The proper tension of an electric furnace heater’s blower belt should result deflection of about one-half to three-fourths of an inch. You can tell if the blower belt has gotten too tight when it starts making an audible noise.
Motor and Blower Pulleys
Place the edge of a carpenter’s square against the outer faces of the motor and the blower pulleys to check for misalignment that can result in wear on the belt and eventually a loss of power. The motor and blower pulleys should be aligned in a straight line at right angels to the motor. Use a hex wrench to loose the motor pulley’s inner setscrew and make adjustments if necessary.
Replace the interior air filter at least once a month during the heating season. If you use a reusable air filter, clean it free of dirt with the heater turned off. Replace and turn the heater back on.
Check for signs of overheating like burned wire insulation or scorched paint located on the housing. Tighten wire connections or replace any damaged wires as needed.
Use a fuse puller to free the fuse to your electric heater from the main service panel if your system still uses fuses. Set a multitester to the RX1 setting to test the fuse for continuity. Touch one probe to the each end cap of the fuse. If the multitester results in a reading of no continuity, replace the fuse.
Baseboard Heater Dirt and Dust
Remove the front panel from a baseboard electric heater so you can clean the dust and dirt from the heating element. Use a dry rag and soft-bristled brush or a vacuum cleaner with a nozzle attachment.
Basebaord Heater Bent Fins
Check the baseboard heater for signs of bent fins after you have finished cleaning it. Use needlenose pliers to straight out any fins that are badly bent. Slightly bent fins can be left alone if you are not able to get them completely straight.
