Lennox furnace error code e228

If you have encountered the Lennox furnace error code e228, it typically indicates a problem with the communication between the furnace control board and the thermostat. This error code can also occur if there is a wiring issue or a malfunctioning control board.

To troubleshoot this issue, first, check the wiring connections between the thermostat and the furnace control board. Ensure that all the wires are securely connected and the connections are not loose or damaged.

If the wiring connections are fine, the next step is to reset the furnace control board. Turn off the power to the furnace and wait for a few minutes before turning it back on. This will reset the control board and may resolve the error code.

If the error code persists, it is recommended to contact a professional HVAC technician to diagnose and fix the issue. They have the expertise and tools required to identify the root cause of the problem and provide an appropriate solution.
