Problem: AC7 Error Code

Solution:

Power off the dryer for 2 to 3 minutes and restart it.

Run a cycle to check if the error code reappears.

If the error code persists, service is needed.

Agent Explanation:

The AC7 error code shows that there's a communication problem between the sub PBA (Sub-Control Board) and the main PBA (Main Control Board). Check the PCB (Printed Circuit Board) and wire harness for any issues. The PCB might need replacement.
