Modine 5H0717640002 Flame Sensor Lead

The Modine 5H0717640002 Flame Sensor Lead is an essential OEM component for Modine PV Series unit heaters and gas-fired appliances. As a direct replacement for 5H71764-2, this lead is engineered to provide a low-resistance electrical path between the flame sensing probe and the integrated ignition control board. Maintaining a stable microamp signal is critical for proper flame rectification, preventing nuisance lockouts and ensuring the burner sustains combustion safely. This HVAC flame sensor wire is constructed with high-temperature insulation to withstand the rigorous conditions within the burner manifold area. In the field, technicians rely on the Modine 5H0717640002 to resolve intermittent ignition failures caused by brittle or corroded wiring. Whether you are performing a seasonal tune-up or a critical repair, using this genuine Modine replacement part ensures full compatibility with factory control logic and helps avoid costly callbacks associated with universal or sub-par aftermarket harnesses.

• OEM Compatibility: Specifically designed as the direct replacement for 5H71764-2, ensuring precise fit and function in Modine unit heaters.
• Signal Integrity: Delivers a consistent, interference-free flame sensing signal to the ignition module for reliable burner operation.
• High-Temperature Durability: Rugged insulation prevents wire degradation in high-heat environments, reducing the risk of ground faults.
• Optimized Combustion: Helps maintain accurate flame detection to minimize fuel waste and prevent flame rollout conditions.

Is the 5H0717640002 compatible with all Modine heaters?
This lead is primarily used in the Modine PV Series. Always cross-reference the Modine part number on your heater’s rating plate and technical manual before installation.

When should I replace the flame sensor lead?
Replace the lead if you detect cracked insulation, excessive corrosion at the terminals, or if the HVAC control board fails to sense a flame despite a clean sensor probe.

Can I use this to replace the older 5H71764-2 part?
Yes, the 5H0717640002 is the official manufacturer-designated direct replacement for 5H71764-2, updated to current technical standards.
