Lennox manufactures residential and commercial furnaces, heat pumps, air handlers and other HVAC equipment. An error code IE is a common error code with Lennox furnaces.

The error code IE may be linked to a sensor failure in a Lennox furnace. Identifying the type of sensor that’s giving you this error message is important before troubleshooting. If this is an outdoor unit, it’s probably due to the outdoor temperature sensor being out of range or not plugged into the circuit board properly. If it’s an indoor unit, it could be one of two things: the indoor temperature sensor malfunctioning or the flame sense switch isn’t connecting with its terminals on the circuit board.

Lennox furnaces are one of the most popular furnace brands on the market. They offer energy-efficient heating, ventilation and air conditioning systems that suit any home.

If a Lennox furnace has an error code IE or P02, the condensate drain tube is clogged or there isn’t enough airflow. There could be a problem with the furnace’s blower motor or another issue in this area.
