Lennox Air Conditioner Error Codes
If you're looking for help fixing your Lennox Air Conditioner, look no further! Our comprehensive Lennox Air Conditioner error code guide will explain common issues, provide tips, and show you how to read your model's error codes.
Lennox air conditioners may have different error codes depending on the specific model and series. Error codes are designed to help identify issues with the system, and they can vary between different units. If you're experiencing problems with your Lennox air conditioner and need to understand the error codes, it's essential to refer to the user manual or technical documentation specific to your model.
As of my last knowledge update in January 2022, here are some common Lennox air conditioner error codes and their possible meanings. Please note that this list may not cover all models, and the actual error codes for your unit may differ:
E1 or 101:
This code may indicate a communication error between the indoor unit and the outdoor unit.
E2 or 102:
A possible refrigerant system issue or a problem with the outdoor coil sensor.
E3 or 103:
This code could be related to a problem with the air filter or air flow.
E4 or 104:
An issue with the outdoor coil temperature sensor or an outdoor coil temperature out-of-range condition.
E5 or 105:
This code may indicate a problem with the power supply voltage.
E6 or 106:
A fault in the communication between the indoor and outdoor units.
E8 or 108:
This code might signal a high-temperature limit trip.
It's crucial to consult the specific documentation provided with your Lennox air conditioner for accurate information about error codes. If you don't have the user manual, you can often find it on the official Lennox website or by contacting Lennox customer support.
If you're unsure about troubleshooting or interpreting error codes, or if the issue persists, it's advisable to contact a certified HVAC technician or Lennox service provider for professional assistance. Working with HVAC systems requires expertise to ensure safe and accurate diagnosis and repairs.

Lennox Air Conditioner common faults
We have had a number of Lennox heating systems and have had very good reliability and operation. As long as you get a qualified company to install properly you would be happy. We have had the higher end products.
My Lennox, variable speed two stage gas furnace, is one year old, 04/04/2019, and I am very satisfied to date. Frankly, no complaints. It came with the iComfort touch screen programmable thermostat which is easy to operate. The furnace satisfies the heating needs of a 2100 sq. ft. home. I would recommend the product.
Replaced my old Lennox HVAC with a newer unit. I must say that I'm impressed with the quality and build of the Lennox units. They look modern and function cleanly. I've seen a dramatic change in my utility bills since replacing my old unit.
Always very helpful with what our company needs and very quickly on searching for products and delivering our orders. I really recommend this branch to all the HVAC needs in the area of Houston Texas.
Our old heat pump worked fine but the agent that came to our home said that even though the heat pump worked okay there were no more parts being manufactured for it. Also, the freon it used was also being phased out. So, we put out the big bucks and bought a top of the line Lennox. Not only was it super efficient in keeping the temp where I set it but our monthly bill dropped. We were total electric and our bill was $140 a month on a budget.
