920920 Nordyne BLOWER BOARD Description 920920 OEM blower control board for Nordyne HVAC equipment. It receives thermostat and sensor inputs, commands the blower relay, and precisely modulates PSC blower motor speeds to optimize airflow, maintain consistent heat rise, and prevent short cycling. The board includes diagnostic LEDs for rapid troubleshooting and built-in delay timers plus overload protection for enhanced reliability. Compatibility This blower control board is compatible with Nordyne and related brand gas furnace applications, including MG2S Series 96% AFUE 2-stage fixed-speed gas furnaces (045F, 045T, 060F, 060T, 072F, 072T). It replaces OEM part numbers 920920 and 624756R, and also fits Intertherm, White-Westinghouse, Frigidaire, Maytag, Tappan, Miller, Gibson, GrandAire, Philco, Garrison, Mammoth, and Medallion models. Compatibility Verification: Match the MPN on your existing control board (920920 or 624756R). Confirm your furnace’s series and model align with MG2S two-stage PSC blower configurations. Cross-reference with the manufacturer’s parts manual or technical support.
