Q2: What are the common symptoms of a failing control board?
A: If your unit is experiencing any of the following issues, it's likely that the control board needs replacement:
The unit does not power on at all, and the display is blank.
No cooling function, even though you might hear the compressor running.
No heating function, or the water doesn't get hot enough.
Both cooling and heating functions have failed simultaneously.
The display shows an abnormal error code.
The unit does not respond to button presses.
Q3: Is the installation complicated? Do I need a professional technician?
A: This board is designed as a direct replacement with matching connectors. However, installation involves electrical safety and knowledge of the appliance's internal components.

For experienced DIYers, we provide an installation guide, but please ensure the unit is completely unplugged before proceeding.
