Frequently Asked Questions (FAQs)

What types of fan motors are supported by this control board?

It supports PG/FG signal indoor fan motors and outdoor DC fan motors.

How does the compressor soft start feature help the system?

The soft start function reduces the initial electrical load during startup, protecting circuit components and extending compressor life.

Can the QD-U08PGC be used on a standard non-inverter air conditioner?

No, this board is strictly engineered for variable-speed DC inverter split systems and cannot be used on fixed-speed non-inverter units.

How do I fix error codes or communication issues after installing the QD-U08PGC?

Check that all temperature sensor harness plugs and PG/FG feedback wires are fully seated, and confirm that the EEV valve connector pins match the board layout per the wiring diagram.

Does this board work with both 50Hz and 60Hz power grids?

Yes, the power supply circuitry on the QD-U08PGC main board is compatible with standard 50Hz and 60Hz single-phase input power.
