Daikin-McQuay 059867701 Flame Rod

The Daikin-McQuay 059867701 Flame Rod is a critical flame safety component designed for high-performance gas-fired appliances. Engineered for precision, this flame sense rod utilizes the flame rectification principle to monitor ion flow during the combustion cycle. When the pilot or main burner ignites, this sensor translates the presence of a flame into a microamp DC signal, providing the necessary feedback to the integrated control board to maintain the gas valve in the open position.

This industrial-grade HVAC replacement part is built to withstand the rigorous thermal stresses of a combustion chamber, preventing hazardous gas accumulation in the event of a flame failure. For service technicians, the 059867701 is an essential OEM flame sensor known for maintaining high signal integrity in Daikin and McQuay systems, ensuring the heating cycle remains stable and efficient. Replacing a fouled or cracked rod with this genuine HVAC flame detector restores system reliability and prevents nuisance lockouts caused by weak flame signals.

• Precise Flame Rectification: Delivers accurate microamp feedback to the control module for instantaneous flame verification.
• Industrial Construction: High-grade metallic rod and ceramic insulator designed for extreme heat resistance and longevity.
• System Safety: Crucial for preventing unburned gas buildup by signaling the control board to shut down the gas valve upon loss of flame.
• OEM Compatibility: Specifically engineered for a direct fit in Daikin-McQuay heating systems, ensuring seamless integration with existing wiring.

• What causes a flame rod to fail? Most failures result from carbon buildup (soot), oxidation, or a cracked ceramic insulator. Technicians should inspect for these conditions during routine maintenance.
• How do I test the 059867701? Use a multimeter to measure the microamp (µA) signal in series with the flame rod circuit during a call for heat; a reading below the manufacturer’s specification typically indicates a dirty or failing sensor.
• Can this rod be cleaned? While light oxidation can often be removed with a non-abrasive pad, a rod with a cracked insulator or significant pitting must be replaced to ensure safe operation.
