Easy Instructions for Cleaning a Furnace Flame Sensor from Experts

At Cambridge Heating and Cooling, we recognize the value of a furnace that is properly maintained, and maintaining the flame sensor’s effectiveness is a key component. A filthy flame sensor can cause several problems, such as erratic cycling and subpar heating. In this article, we offer professional advice on how to efficiently clean a furnace flame sensor, ensuring that your furnace performs at its best throughout the seasons.

1. Knowledge of the Flame Sensor

Understanding the function of the flame sensor is crucial before beginning the cleaning procedure. Your furnace’s flame sensor is a safety feature that looks for flames. It turns off the furnace to stop unburned gas from entering your home if it detects no flame while the gas valve is open.

2. Turn off the power first and foremost for safety

When handling any furnace component, safety must always come first. Start by cutting the furnace’s electricity. To protect your safety when cleaning your furnace, find the power switch or circuit breaker attached to it and flip it off.

3. Accessing the Flame Sensor

Usually, the burner assembly has a tiny metallic rod that serves as the flame sensor. When the furnace is functioning, it is situated in the flame’s path. Remove the flame sensor with care, making note of where it is located and how it is linked. One or two screws hold most flame sensors in place.

4. Cleaning the Flame Sensor

Clean the flame sensor’s surface lightly with an emery cloth or a soft, abrasive pad. Sandpaper shouldn’t be used since it might be overly abrasive and harm the sensor. Its functionality may be hampered by accumulated dirt, soot, or oxidation, which must be removed.

5. Testing and Reassembling

After cleaning, carefully reinstall the flame sensor in its original location. Verify that it is well fastened and replace any missing screws. After reassembly, turn on your furnace again and see it in action. Your furnace will start without a hitch if your flame sensor has been cleaned properly.

6. Regular Upkeep for Long-Term Effectiveness

For your furnace to remain efficient and dependable over the long term, routine maintenance is essential, which includes cleaning the flame sensor. To make sure all parts, including the flame sensor, are in top shape, we advise scheduling yearly expert maintenance.
