Omar for Model Number GC5SHEXNS03 My Whirlpool refrigerator makes this pinging noise (see video link at bottom). I replaced the Evaporator motor and fan. I replaced the control board in the refrigerator behind the temperature displays. Took off the back cover and the ping seems to be coming from there. https://www.youtube.com/watch?v=Iq32XHcmPf8&feature=em-upload_owner#action=share
Answer Hello Omar, Whirlpool Model Numbers starting with EC or GC have an alarm that beeps. To correct the issue, Press and release the freezer door switch. If this restores operation, add a plastic shim block, WP2177331 to the freezer liner where it contacts the light switch. This will increase the travel of the light switch actuator. Confirm that the freezer light bulbs are off when the door is closed. Read More... Answered by AppliancePartsPros.com | Thursday, April 13, 2017
