Whirlpool 10735201 Flame Sensor

Product Description

The Whirlpool 10735201 is a flame sensor designed for use in gas-fired heating equipment. The flame sensor monitors burner operation by detecting the presence of a flame through the principle of flame rectification. When the burner ignites, the sensor passes a small current through the flame and signals the control board that combustion is confirmed. If no flame is detected within the trial-for-ignition period, the control board initiates a lockout sequence to prevent unburned gas from accumulating. This part is typically installed by licensed HVAC technicians during routine maintenance or troubleshooting of heating systems with ignition or lockout faults.

The 10735201 flame sensor is suited for residential gas heating applications. It is commonly replaced during no-heat calls where the system short-cycles, fails to stay lit after ignition, or repeatedly enters lockout mode. A contaminated or corroded flame sensor rod is one of the most frequent causes of nuisance lockouts in gas furnaces, making this a high-frequency service part for HVAC technicians. Proper sensor rod positioning relative to the burner flame envelope is critical for reliable operation.

Key Features

• Flame rectification design confirms active combustion and signals the control board
• Replaces a failed or contaminated OEM flame sensor rod assembly
• Designed to integrate with the existing control board lockout and retry logic
• Compact sensor rod construction suitable for residential gas furnace burner assemblies

Compatibility

Designed as an OEM-style replacement flame sensor for residential gas furnace heating systems manufactured under the Whirlpool brand.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut off power to the furnace and close the gas supply valve before beginning service. The sensor rod surface should be lightly cleaned with fine steel wool if contamination is present before installing the replacement. Reinstall according to the appliance service manual and verify flame signal voltage at the control board after startup to confirm proper operation.
