Why is the discharge pressure high on my Midea MGA-F30W/SN1 Chiller (cooling mode)?
- BBrian ColemanAug 14, 2025
High discharge pressure in a Midea Chiller during cooling can occur if air or another gas enters the system. To resolve this, discharge the gas from the refrigerant charging hole and re-vacuum if necessary. It can also happen if the fins are dirty or blocked; in this case, splash the fins of the condenser. Finally, check the condenser motor and repair it if it's faulty, because insufficient condenser wind flow or motor failure can also cause high discharge pressure.
