Frequently Asked Questions
•What is the part number for the main control board in my Whirlpool refrigerator?
The part number for the main control board is specific to your refrigerator's model number. Locate the model number inside the refrigerator (usually on a sticker on the side wall) and use it to search for the correct control board part number online or at a local appliance parts store.
•How do I test the water filter sensor with a multimeter?
Set your multimeter to the continuity setting (usually indicated by a diode symbol or audible beep). Disconnect the sensor from the main control board. Place the multimeter probes on the sensor terminals. With the filter removed, you should see an open circuit (no continuity). With the filter installed, you should see a closed circuit (continuity).
•Where is the water filter sensor located?
The water filter sensor is typically located inside the filter housing. It's a small switch that detects the presence of the filter. You may need to partially disassemble the filter housing to access it.
