A couple of different methods exist for resetting a Whirlpool ED22RF refrigerator. You may need to reset the whole refrigerator if you are cleaning the refrigerator or replacing a light bulb. On the other hand, you may need to reset the ice maker within the appliance if you changed the water filter and desire the base grille water status light to go back to its normal settings.
Turn the refrigerator's temperature control knob to the "Off" position.
Remove the power cord from the wall outlet.
Reconnect the power cord to the wall outlet.
Turn the temperature control knob to the desired temperature.
Reset Ice Maker
Locate the switch next to the water filter status light.
Press the light switch five times in 10 seconds or less.
Wait for the status light to change from red to green.
