An E154 error could mean the indoor unit has detected a problem with the blower fan that circulates air through your room. Instead of spinning as commanded, the fan motor has either stopped, stalled, or is behaving in a way the control board doesn’t recognise as normal operation.
Since the indoor fan is what actually delivers conditioned air into the space, this fault usually comes with reduced or no airflow from the unit even if the compressor is still trying to run. It’s generally a mechanical or electrical issue at the fan itself rather than anywhere else in the system.
Send us the code and a photo of the display, and a Ford & Doonan technician will get back to you. Please don't reset the unit before you take the photo.
