How to Troubleshoot a Honeywell Electronic Furnace Filter


The Honeywell Company manufactures many different products for homes and businesses, including electric and gas furnaces and furnace filters. Honeywell electronic furnace filters capture up to 99 percent of particles in the air and are an economical and environmentally friendly option to provide increased air quality. Troubleshooting a Honeywell electronic furnace filter takes only a few steps and may help eliminate problems prior to calling a service technician for help.

Things You'll Need

  • Power supply
  • Tools (if necessary)
  • Clean cloth
  • Water
  • Ensure the furnace is turned on and plugged into a working power supply if the filter does not seem to be working. Listen to the furnace while it is in operation to ensure the blower is running.

  • Check the front access panel on the furnace and ensure it is closed tightly and latched if the air cleaner is not functioning well.

  • Turn the furnace off and leave it off for two to three hours if a snapping sound is heard frequently from the furnace. This allows the filter to dry, as it may have come in contact with moisture.

  • Turn off the furnace and unplug it from the electric supply if the snapping noise continues after restarting the furnace. Open the front access panel and look at the Honeywell electronic filter. Examine the filter for broken wires or bent plates and replace if broken or damaged.

  • Wipe the filter cells clean with a damp cloth if excessively dirty. Allow two to three hours for them to dry before closing the front access panel and reconnecting the power to the unit.

  • Contact an authorized service technician if the above steps do not resolve the problem.
