If you're looking for help fixing your Lennox Furnace, look no further! Our comprehensive Lennox Furnace error code guide will explain common issues, provide tips, and show you how to read your model's error codes.

Lennox furnace error codes can help diagnose issues with your heating system. However, the specific error codes can vary depending on the model of your Lennox furnace. It's essential to consult your furnace's user manual or the technical documentation provided by Lennox to interpret the error codes accurately.

Here are some common Lennox furnace error codes and their potential meanings. Keep in mind that these are general examples, and your specific model may have different codes:

E228: This code may indicate an issue with the flame sensor. It's advised to check the flame sensor for cleanliness and proper operation.

E270: This code may point to a problem with the pressure switch. Verify that the pressure switch is functioning correctly and that there are no obstructions in the venting system.

E292: This code might indicate a problem with the ignition control. Check for proper voltage and ensure that the ignition system components are working as they should.

E223: This code may be related to an issue with the blower motor or capacitor. Inspect the blower motor and its components for faults.

E228: This code may also relate to flame sensor issues. Cleaning the flame sensor is a common solution for this error.

It's crucial to note that error codes are specific to the furnace model, and the troubleshooting steps may differ. Always refer to the manufacturer's documentation or contact Lennox technical support for accurate information based on your furnace model.

If you are not comfortable troubleshooting or if the issue persists, it's recommended to contact a qualified HVAC professional to inspect and repair your furnace. Performing DIY repairs without proper knowledge can lead to further complications or safety hazards.

I bought Lennox elite EL296UH070XV36B-02 furnace on Aug 29, 2012. In Oct 5, 2022 the blower is stop working just one month past the end of warranty. There is no any error code on the control board. I did search through internet and did some test and looks like the motor control module has issues. I take the module to parts and try to test it, but I cannot find any technical documentations show the spec of the 3 pin connector to motor. So there is no way to confirm this part is really bad or not. In the end I spent $456. Bought a new module (It is a non re-fundable part). Fortunately my bet is in the right side.

I replaced my HVAC system this year. I replaced my Lennox Gas Furnace and Trane Central Air Conditioner unit which were about 20 years old and were trouble free. The new Lennox units are unbelievably quiet and seem to be more energy efficient than my older units.

I wanted to take the time to write a good review since most people only bother to write reviews when they have an problem. After all when you buy a new product you expect it to work so why would you bother to write a review for that! Well I decided to write this because as most of you are probably doing now, you’re contemplating buying a Lennox but are reading reviews first, and like you I found mostly negative things. I’m not sure it made me feel much better but all the brands I researched had mostly bad reviews. So here’s my experience... I installed a fully modulating furnace (SLP98) and A/C (XC20) along with the WiFi stat and let me tell you it’s awesome! Quietest and most efficient units I’ve ever had. The one thing I also kept reading for Lennox is that parts are hard to get.
