Frigidaire Gallery Refrigerator: PureAir Filter Reset... | appliancefaults.com

Technical Background:

The PureAir filter reset function relies on communication between the user interface (UI) board and the main control board. When the reset button is pressed, the UI board sends a signal to the main control board, which then resets the filter timer. This signal is typically a low-voltage DC signal. The voltage path is critical for proper operation. The MCU (Microcontroller Unit) on the UI board must correctly interpret the button press and send the reset signal. A break in the voltage path, or a faulty MCU, can prevent the reset function from working.

Symptoms:

The PureAir filter reset button on your Frigidaire Gallery refrigerator is not responding when pressed. The indicator light may remain on, or the filter replacement reminder may not clear.

Possible Causes:

Faulty user interface (UI) board.
Defective touch sensor for the PureAir filter reset button.
Wiring harness issue between the UI board and the main control board.
Main control board failure affecting UI communication.
Stuck or shorted button on the UI board.

Solution:

1

Disconnect power to the refrigerator by unplugging it or switching off the breaker (120V AC).
2

Locate the user interface (UI) board, usually behind the dispenser panel or inside the refrigerator near the control panel.
3

Carefully remove the UI board. Inspect the wiring harness connector for corrosion or loose connections. Re-seat the connector.
4

Using a multimeter, check the voltage supply to the UI board (typically 5V DC) from the main control board. Refer to the wiring diagram.
5

If voltage is present, test the continuity of the reset button using the multimeter. The resistance should change when the button is pressed.
6

If the button shows no change, the UI board is likely faulty and needs replacement. Order a new UI board with the correct part number.
7

If voltage is absent, troubleshoot the wiring harness and the main control board.

Safety Warning:

Always disconnect power to the refrigerator before performing any repairs. High voltage is present when the appliance is powered on. Use proper Lock Out Tag Out (LOTO) procedures to prevent accidental electrocution.

Prevention:

Replace the PureAir filter according to the manufacturer's recommended schedule (usually every 6 months). This prevents excessive strain on the filter system and reduces the likelihood of control board issues. Periodically inspect the UI board area for moisture or damage.

Expert Tip:

Some Frigidaire Gallery models have a diagnostic mode accessible through a specific button sequence (consult service manual for the exact sequence). Entering this mode may allow you to test the functionality of individual buttons on the UI board.

Frequently Asked Questions

•How do I find the wiring diagram for my Frigidaire Gallery refrigerator?

The wiring diagram is often located on the back of the refrigerator, inside the control panel housing, or available online through the manufacturer's website or appliance parts suppliers.

•What is the part number for the UI board on my specific Frigidaire Gallery model?

The part number is specific to your model. Check the model number located on the refrigerator's interior wall or the exterior back panel. Then search online using the model number and 'UI board part number' to find the correct replacement part.

•Can a faulty water filter also cause problems with the PureAir filter reset?

While not directly related, a clogged or improperly installed water filter can sometimes cause issues with the refrigerator's overall performance and potentially affect the operation of other features. Ensure the water filter is correctly installed and replaced according to the recommended schedule.
