preventing capacitance drift during high-ambient operations

Direct Fit Installation: Features standard lead lengths and mounting configurations for fast swaps during service calls

Dual-Function Technology: Acts as both direct spark ignitor and flame sensing rod to ensure safe furnace sequences

Always verify that the pilot generator is producing at least 600-750mv under load before condemning the millivolt gas valve

Green Color Coding: Simplifies part identification during installation and maintenance in complex HVAC control circuits

Nordyne 669568R TXV 320788-704 preventing capacitance drift during high-ambientThe Nordyne 669568R TXV is a precision engineered OEM R410A thermal expansion valve designed for specific 4 ton evaporator coils. As a direct replacement for 669568, this 4 ton expansion valve is a critical component for maintaining precise superheat control in high efficiency cooling systems. In the field, we know that accurate refrigerant metering is the difference between a high performing system and one plagued by evaporator icing or compressor
