High-Reliability Safety: The "one-shot" mechanism eliminates the risk of a technician manually resetting a control on a failing or restricted system

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

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

It is specifically designed for direct mounting to VG1000 series ball valves

Nordyne 921104 Coil Assembly 326058-758 High-Reliability Safety: The "one-shot" mechanismThe 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,
