Wayne 62390-002 Probe Sensor

The Wayne 62390-002 Probe Sensor (F/HSG) is a critical replacement flame monitoring component designed for the EHG and HSG Series Gas Burners. Engineered for high-temperature stability, this assembly features a precision-machined metal rod and a high-grade white porcelain insulator. In standard burner ignition sequences, the probe serves as the primary communication link with the gas valve; it detects the presence of a flame via rectification and signals the control module to maintain gas flow. Failure to detect this ionization current results in an immediate safety lockout, preventing unburned gas accumulation.

For technicians servicing Wayne Combustion systems, this probe is compatible with EHG models featuring 9-inch, 12-inch, or 15-inch air tube configurations. The robust construction is specifically built to withstand the rigorous cycles of industrial and commercial heating applications. To ensure optimal signal strength and system reliability, the probe surface must remain free of carbon deposits and the porcelain insulator must be inspected for hairline fractures that could cause grounding issues. This genuine OEM part ensures direct-fit compatibility, maintaining the original engineering specifications of the burner housing.

• Precise Flame Detection: High-sensitivity metal electrode ensures accurate ionization signaling to the burner control module.
• Thermal Resistance: Premium porcelain insulator prevents voltage leakage even under extreme operating temperatures within the burner housing.
• Broad Compatibility: Designed for seamless integration with Wayne EHG and HSG Series burners.
• Safety Compliance: Reliable flame monitoring prevents hazardous gas buildup by ensuring the fuel valve only remains open during active combustion.
• OEM Durability: Genuine construction provides superior service life compared to generic aftermarket alternatives.

• What causes a Wayne flame sensor to fail? Most failures are due to carbon soot buildup on the rod or cracks in the porcelain insulator caused by thermal shock, leading to "false-no-flame" lockouts.
• Can this probe be cleaned? While light oxidation can sometimes be removed with a fine abrasive, deep pitting or damaged ceramic insulators require a full replacement of the 62390-002 assembly to ensure safety.
• How do I verify compatibility with my air tube? This sensor is specifically engineered to fit Wayne EHG burners with 9, 12, and 15-inch air tubes as well as HSG series equipment.
