Professional Flame Sensor Cleaning
Fix ignition problems and ensure reliable furnace operation with expert flame sensor maintenance
Understanding Your Furnace's Flame Sensor
The flame sensor is a critical safety component that ensures your furnace operates safely and efficiently
How It Works
The flame sensor detects the presence of a flame in your furnace's combustion chamber. When it senses a flame, it signals the gas valve to stay open. If no flame is detected, it immediately shuts off the gas supply for safety.
- Detects flame presence for safety
- Controls gas valve operation
- Prevents gas buildup and hazards
- Ensures proper ignition sequence
Signs You Need Flame Sensor Cleaning

Flame Sensor Cleaning FAQ
Flame sensors should typically be cleaned annually as part of regular furnace maintenance, or immediately if you're experiencing ignition problems.
While possible, professional cleaning ensures proper technique, safety, and thorough testing. Improper handling can damage the sensor or create safety hazards.
Professional flame sensor cleaning typically takes 30-45 minutes, including removal, cleaning, reinstallation, and testing.
Normal combustion creates deposits on the sensor over time. Poor air quality, dirty filters, and incomplete combustion can accelerate buildup.
If short cycling is caused by a dirty flame sensor, cleaning will resolve the issue. However, other problems may require additional diagnosis and repair.
