Furnace Error Codes: What Do They Mean?

How to read and respond to issues with your oil or gas-fired heating equipment.

furnace repair Medway, MA For the most part, when your home’s furnace is functioning properly, there shouldn’t be any fast-blinking lights or illuminated codes. Today’s oil and gas-fired furnaces run smoothly and relatively quietly. So, if you notice an unusual light flashing on your equipment, it’s a good idea to look up the error code and find out if something needs immediate attention from an HVAC professional.

At TF Complete Heating & Cooling, we can assist with errors on a wide range of furnaces to ensure your home heating keeps working through the iciest New England winters.

Different brands have different error codes.

Pretty much all manufacturers put a series of flashing LED lights on their furnaces to alert you to an error, and the color and pattern of these lights will tell you what the exact issue is. Unfortunately, there isn’t a universal code for these errors. Different brands have different error codes.

To “decode” these flashing lights, either check your furnace’s installation manual or go to the manufacturer’s website to find the code list.

Here are some common errors for furnaces.

If your furnace is flashing an error code, the underlying issue could be:

This is not an exhaustive list. It’s a rundown of common issues that can trigger a furnace error code.

Do not attempt your own furnace repair.

If you notice one of the furnace issues listed above — or if you’re unable to determine what’s causing your furnace error signal — please immediately contact a licensed HVAC repair technician like the team at TF Complete Heating & Cooling.

Furnace repair is not a “do-it-yourself” home project. Today’s heating equipment is complex, and it connects to heating oil tanks or gas lines. If you try to fix the error yourself, you could trigger a dangerous gas leak or a costly oil spill. Even if the result isn’t a health hazard, you could severely impair your furnace’s performance.

The good news is that if you’ve arranged regular service for your heating equipment, the cost to repair a standard furnace error could be modest. The key is to bring in a professional right away.
