The Mitsubishi MAC-642BH-U1 is designed for use with outdoor units like the MUZ-GE24NA. This base pan heater helps to prevent ice buildup in cold conditions, which can damage the condenser. The heater connects to the control board and activates automatically when the temperature drops below thirty-six degrees Fahrenheit or when the system enters defrost mode.
The MAC-642BH-U1 is essential for maintaining the efficiency of your outdoor mini split system during winter months.
