In most cases the problem could be solved by cleaning the flame sensor. But before cleaning, you must get access. We have for you an instruction how to get access and how to clean a furnace flame sensor. Let’s start.
The flame sensor is usually mounted on or near the burner assembly in the furnace. While the steps required to access the sensor can vary depending on the furnace model, there are some general guidelines you can follow:
- For safety, be sure to shut off the power to the furnace before you remove any panels. You should shut off the gas supply as well.
- You may be able to simply slide the upper or lower compartment access panel upwards to detach. Otherwise, you will probably need to rotate or unthread two retaining knobs, or unthread mounting screws, before you can remove the panel.
- The flame sensor is usually secured to the burning housing with a single mounting screw. Unthread the screw and carefully pull the sensor out of the housing.
- Keep in mind, you may need to first disconnect the wire from the sensor to fully remove it from the housing or to have better access to the sensor to clean it.
How to clean? You can use Emery cloth sandpaper or a fine abrasive pad to gently clean any build-up from the flame sensor’s sensing rod. If present, you should also clean off any corrosion where the power wire connects to the flame sensor terminal. Use a lint-free cloth to wipe the component clean of any remaining debris.
- When you’ve finished cleaning the sensor, reseat it in the burner housing and secure it with the mounting screw.
- Reconnect the wire to the sensor terminal.
- Reposition the access panel and secure it with the mounting screws or retaining knobs as required.
- Turn the gas supply back on and restore power to the furnace.
- Call for a higher temperature on your home’s thermostat and observe if the furnace now appears to be functioning normally.
