How to Clean Furnace Sensor?
Cleaning your furnace sensor is an important maintenance task that should not be overlooked. A dirty sensor can cause your furnace to malfunction, leading to costly repairs and even potentially hazardous situations. In this article, we will walk you through the steps to properly clean your furnace sensor.
Gather Your Materials
The first step in cleaning your furnace sensor is to gather all the necessary materials. You will need a soft-bristled brush, a clean cloth, and a can of compressed air. You may also want to wear gloves and eye protection for added safety.
It’s important to note that you should never use water or any type of liquid cleaner on your furnace sensor. Moisture can damage the sensor and cause it to malfunction.
Turn Off the Power
Before you begin cleaning your furnace sensor, you need to turn off the power to your furnace. Locate the power switch or circuit breaker and turn it off. This will ensure that there is no electricity running through your furnace while you clean the sensor.
It’s also a good idea to wait a few minutes after turning off the power to allow the furnace to cool down before you begin cleaning.
Remove the Sensor
The next step is to locate the sensor and remove it from the furnace. The sensor is typically located near the burner assembly and is attached to the furnace with a screw or clip.
Once you have removed the sensor, inspect it for any visible signs of dirt or debris. Use the soft-bristled brush to gently brush away any dirt or debris on the surface of the sensor.
Clean with Compressed Air
After brushing away any visible dirt or debris, use the can of compressed air to blow away any remaining particles. Hold the can upright and use short bursts of air to avoid damaging the sensor.
Be sure to blow air through the small holes on the sensor as well to ensure that they are clean and clear.
Reinstall the Sensor
Once you have finished cleaning the sensor, it’s time to reinstall it back into the furnace. Be sure to reattach the sensor securely with the screw or clip.
After the sensor is reinstalled, turn the power back on to your furnace and test to make sure it is working properly.
