GE RPWFE Filter Bypass: Removing the Chip - Step-by-Step... | appliancefaults.com

Technical Background:

The GE RPWFE filter system uses an RFID chip embedded in the filter to communicate with the refrigerator's control board. This chip verifies that a genuine filter is installed and monitors its lifespan. The control board uses a low-voltage DC circuit to read the chip. When a filter expires or is bypassed improperly, the control board disables water dispensing and ice making. The control board sends a signal to a valve that allows water to flow. If there is no proper reading from the filter or the bypass, it stops the water flow to the dispenser.

Symptoms:

The refrigerator is not dispensing water or ice after a filter change or after attempting to bypass the filter. The refrigerator may display a "Replace Filter" message or an error code, even with a new filter or bypass plug installed. The homeowner reports using a Dremel to modify the filter or bypass plug to attempt a workaround.

Possible Causes:

Damaged or missing RFID chip in filter or bypass plug.
Incorrect bypass plug system.
Faulty refrigerator control board.
Wiring issues between the filter housing and the control board.
Software glitch or error requiring a control board reset.
Improper water pressure affecting filter recognition.

Solution:

1

Disconnect the refrigerator from power at the breaker panel (Lock Out/Tag Out).
2

Inspect the RPWFE filter housing for physical damage. Check the electrical connector for corrosion or loose wires. Use a multimeter to check continuity of wiring harness.
3

Verify the correct bypass plug is installed and properly seated. Ensure the plug's RFID chip (if present) is intact.
4

Check the water pressure to the refrigerator. It should be within the manufacturer's specified range (typically 40-120 PSI). Use a pressure gauge connected to the water line.
5

Access the refrigerator's control board (typically located behind the back panel or inside the top control console). Visually inspect the board for burned components or damaged traces.
6

Use a multimeter to check the voltage at the filter sensor connector on the control board. Refer to the wiring diagram to determine the expected voltage (likely 5V DC or 12V DC).
7

If the voltage is incorrect, or the board shows signs of damage, replace the control board. Ensure you purchase the correct replacement part number.

Safety Warning:

Always disconnect power to the refrigerator at the breaker panel before performing any repairs. Lock Out/Tag Out (LOTO) procedures must be followed. Some components may carry 120V AC. Exercise caution when working with electrical components.

Prevention:

Use only genuine GE RPWFE filters. Replace the filter every six months or as indicated by the refrigerator's display. Avoid modifying or tampering with the filter or bypass plug.

Expert Tip:

Some GE refrigerators have a service mode that allows you to bypass the filter temporarily for diagnostic purposes. Consult the service manual for your specific model to determine the access procedure, often involving pressing specific button combinations in sequence, such as holding the Freezer and Ice Maker buttons simultaneously for 3 seconds.

Frequently Asked Questions

•How can I test the RFID chip on the filter or bypass plug?

You'll need an RFID reader/writer that operates at the frequency used by the GE RPWFE filters. Unfortunately, these are not typically available to consumers. A professional appliance technician may have access to such a device.

•What is the correct part number for the RPWFE bypass plug for my GE refrigerator model?

The correct bypass plug part number depends on your specific refrigerator model number. Refer to your refrigerator's parts diagram or contact GE customer service with your model number to obtain the correct part number. The bypass plug for many models is part number GERPWFE-BYPASS.

•If the control board is replaced, does it need to be programmed or calibrated?

In some cases, replacing the control board may require programming or calibration. This depends on the specific model and the features it has (e.g., dispenser calibration, temperature sensor calibration). Consult the service manual or GE's technical support documentation for your refrigerator model to determine if any programming is required after control board replacement. Some newer models automatically calibrate.
