Precise resistance values ensure the system logic avoids unnecessary short-cycling or incorrect delta-T calculations

Key Benefits OEM Compatibility: Precision-engineered for Weil-McLain GV90+ Series 1 and 2

this indicates that the incoming gas supply has dropped below the 5" WC threshold

since it is a two-position device

The automatic reset design eliminates manual intervention after the unit cools to 200°F

Nordyne 921104 Coil Assembly 326058-758 Precise resistance values ensure theThe Nordyne 921104 Coil Assembly is a high performance OEM replacement evaporator coil engineered to restore thermal transfer efficiency in gas furnace and split system configurations. As a direct replacement for obsolete HVAC coils, this assembly is critical for maintaining the correct refrigerant to air heat exchange, preventing premature system cycling. This unit is designed for compatibility with specific Nordyne, Intertherm, and Miller series,
