Midea Dryer Error Code E4

The E4 code means the humidity sensor detecting circuit on the main control board is damaged. This circuit reads moisture levels in the drum to determine when clothes are dry. The dryer will still complete cycles using timed drying as a fallback, but the automatic moisture-sensing function is disabled. The code is displayed or logged at the end of the cycle rather than interrupting it.

A reset will not permanently clear E4 because the fault is tied to physical damage in the humidity sensing circuit on the main control board. The code will return at the end of the next cycle since the underlying hardware issue has not been resolved. Clearing the error requires repairing or replacing the main control board.

Repair costs depend on whether the main control board needs full replacement or can be repaired at the component level. A replacement control board typically costs anywhere from $80 to $200 or more for the part alone. Adding professional labor, total repair costs can range from $150 to $350 or higher depending on your location and service provider.

Yes, the dryer will continue to operate using timed drying mode even when E4 is present. Your laundry will still be dried, but the dryer will not automatically stop based on moisture detection. You will need to select your drying time manually and may need to check clothes to avoid over-drying or under-drying.

Running the dryer with an E4 error is generally safe for continued use since the machine falls back to timed drying mode. However, without moisture sensing, there is a greater chance of over-drying fabrics, which can cause wear over time. It is best to address the control board fault when possible to restore full functionality.
