Understanding Lennox Error Codes

Lennox furnace error codes appear on the device’s LED display located on its control board. The LED flashes in a series of long and short pulses, each coded to represent different problems. Understanding these codes not only helps in quicker troubleshooting but can also give insights into maintaining the furnace properly.

Common Lennox Furnace Error Codes and What They Mean

Code 1 — Watchguard, Burners failed to ignite. This error most commonly arises from a problem with the furnace’s gas supply. But it can also be due to a faulty ignitor or an obstructed burner. A professional inspection might be needed if the basic checks don’t work.

Code 2 — Pressure switch open with the inducer on. This code can signify an issue with the pressure switch circuit or improper venting. It might help to inspect vent pipes for blockages and make sure the furnace’s drainage system is functioning well.

Addressing Lennox Furnace Errors

Most of the time, you can reset the Lennox furnace error codes simply by switching the furnace off, and then turning it back on after some minutes. However, not all issues might be resolved with this simple reboot. More serious concerns usually require professional assistance.

Preventive Measures to Avoid Errors

It is true that ‘prevention is better than cure’, and your Lennox furnace is no exception. Regular preventive maintenance can often avert minor errors from turning into major problems. Make sure to clean or replace filters on a regular basis, ensure proper airflow, and clean the blower as necessary. An annual professional check-up comes highly recommended to keep your furnace in good working condition.

When Should you Seek Professional Help?

Deciding when to call in a professional can be a bit challenging. If your Lennox furnace error code persists even after your basic troubleshooting, or if issues recur frequently, it’s probably time to call in a professional. Also, if the furnace is giving off an unusual smell or noise, it indicates a more serious problem which is best left to professionals.
