Hotpoint Refrigerator Air Filter Change Light Won't... | appliancefaults.com

Technical Background:

The refrigerator's MCU monitors the air filter usage based on a timer or airflow sensor. When the set time or airflow threshold is reached, it triggers the 'Change Air Filter' light. Resetting the light usually involves signaling the MCU via a button press to restart the timer or recalibrate the sensor. The UI control panel sends a low voltage signal to the MCU.

Symptoms:

The 'Change Air Filter' light on your Hotpoint refrigerator remains illuminated even after replacing the air filter and attempting to reset it using the designated button or procedure.

Possible Causes:

Incorrect reset procedure
Faulty user interface (UI) control panel
Stuck or defective button on the control panel
MCU (Microcontroller Unit) malfunction
Power supply issue to the control board
Software glitch requiring a reset or update

Solution:

1

Locate the air filter reset button, usually near the display or filter housing.
2

Press and hold the reset button for 3-5 seconds. Refer to the user manual for the precise duration.
3

If the light doesn't reset, try power cycling the refrigerator. Unplug the refrigerator from the outlet for 5 minutes.
4

Plug the refrigerator back in and check if the light has reset. Try the reset procedure again.
5

Inspect the UI control panel for any physical damage or stuck buttons. Clean the control panel with a soft, dry cloth.
6

Using a multimeter, check the voltage at the control board. You should read approximately 120V AC from the power supply.
7

If the voltage is correct and the light still won't reset, the control board may be faulty and require replacement. Consult a qualified appliance technician.

Safety Warning:

Always disconnect power to the refrigerator at the breaker panel before performing any repairs or maintenance. Be aware of high voltage components within the refrigerator's control system. Follow Lock-Out/Tag-Out (LOTO) procedures.

Prevention:

Replace the air filter every 6 months or as recommended by the manufacturer. Regularly clean the refrigerator's condenser coils to ensure proper airflow and prevent strain on the cooling system.

Expert Tip:

Some Hotpoint refrigerators have a service mode. To enter, simultaneously press and hold the 'Freezer Temp Down' and 'Refrigerator Temp Up' buttons for 10 seconds. This may allow you to manually reset the air filter light.

Frequently Asked Questions

•Where is the air filter located on my specific Hotpoint refrigerator model?

The air filter is typically located inside the refrigerator compartment, either at the top, back, or near the crisper drawers. Refer to your user manual for the exact location and filter replacement instructions.

•How can I test if the reset button on the control panel is functioning correctly?

Using a multimeter in continuity mode, you can test the button's switch. Disconnect power first. Access the control board and locate the button's terminals. When the button is pressed, the multimeter should show continuity (a closed circuit).

•If the control board needs to be replaced, where can I find a replacement part?

You can find replacement control boards at appliance parts retailers like AppliancePartsPros.com or RepairClinic.com. Ensure you have the refrigerator's model number to order the correct part.
