Furnace Error Codes – An S.O.S. From Your Furnace

How to Manage Furnace Error Codes in Your West Virginia Home

Modern gas furnaces are regulated by circuitry known as an integrated furnace control (IFC). It monitors your furnace’s systems and shuts the unit off if it senses a malfunction. Error codes then display to assist with diagnostics and repairs. It’s important to remember that error codes only indicate what sensor tripped. They do not indicate why a sensor has shut the unit down or whether the sensor is functioning correctly. It may be prudent to call someone who provides affordable HVAC repair in Hagerstown, WV to troubleshoot the code and correct the malfunction.

Some Common Faults That Could Trigger The IFC

  • Overheating – This is usually the result of restricted air flow over the heat exchanger, typically due to backpressure from a clogged filter.
  • Flame Rollout – This is a condition that occurs when corrosion has diminished the flow of air through the burner section of your furnace, preventing proper exhaust. Flames are allowed to “roll out” of the area they’re meant to be in, where they can damage components not designed to withstand high heat.
  • No Flame Sensed – This error indicates there’s no fire to ignite the gas feeding your furnace. The furnace shuts down to prevent combustible gases from building up and causing an explosion hazard.
  • IFC internal failure – The IFC could also fail. If that happens, your furnace will shut down to prevent unsafe operation from going undetected.

Understanding Codes

Furnaces are labeled with information tables that indicate what each error code means. Error codes are not standardized across different furnace manufacturers, which can be confusing. It’s best to bring in an expert for affordable HVAC repair in Hagerstown, WV to inspect your furnace and interpret any codes. They are equipped with the tools and know-how to quickly address the problem so you can be comfortable again.
