What to do if my Toshiba Air Conditioner displays an E28 error?
- DDeborah RodriguezJul 30, 2025
If your Toshiba Air Conditioner shows an E28 error, check the display on the interface P.C. board of the corresponding follower unit. Also, inspect the position or part of the header unit. If the error persists, the microprocessor may be malfunctioning due to power supply issues or external noise. In this case, if there is any noise source, consider changing the wires of the remote controller and signal wires to shielded wires.
