What Does Code E 202 Mean?

Error code E202 on the Lennox EL296UHV indicates that the indoor blower motor's horsepower rating does not match what the control board expects for the configured unit capacity. This is a configuration error rather than a mechanical failure.

The EL296UHV control board is programmed with a unit size code that tells it what capacity furnace it is installed in. Based on that code, it expects a specific blower motor. If the motor installed does not match — either because the wrong motor was installed during a repair, or because the unit size code was set incorrectly during installation or configuration — the board flags E202.

The error clears after the correct match is detected following a power reset. A technician needs to verify the appliance capacity code is set correctly per the configuration guide in the installation instructions, and confirm the correct blower motor is installed for the furnace model.
