Description
The AAON V62780 is a genuine OEM flame sensor designed as a direct replacement for compatible AAON commercial HVAC rooftop units and air handling equipment. Flame sensors are a critical safety component in gas-fired heating systems, continuously monitoring the burner flame and sending a signal to the ignition control board to confirm safe combustion. If the sensor fails to detect a flame — or detects one when none should be present — the control board will lock out the system, preventing unsafe operation.
Key Features
- Genuine AAON OEM replacement part — ensures proper fit and function
- Designed for accurate flame rectification signal output
- Supports reliable burner lockout protection in gas-fired HVAC systems
- Direct drop-in replacement to minimize downtime during service calls
- Compatible with select AAON commercial rooftop and air handling units
Application
This flame sensor is intended for use in AAON commercial HVAC equipment. Always verify compatibility with your specific unit model and serial number before installation. Consult the equipment’s service manual or contact AAON technical support for model-specific guidance.
Why Replace Your Flame Sensor?
- Nuisance lockouts or no-heat calls caused by a weak or dirty sensor signal
- Sensor rod oxidation or carbon buildup reducing conductivity
- Preventive maintenance during annual burner service
- Control board diagnostics indicating a flame sense fault
Keep your AAON equipment running safely and efficiently with the V62780 flame sensor — a straightforward, reliable fix for one of the most common commercial heating service issues.
