4YET18PKAN01 Whirlpool Refrigerator

Removed 2 screws holding water fill tube to rear of refrigerator and pulled out, matched old part with new to make sure of proper match. Guide new fill tube thru hole, making sure it is aligned with slot in ice cube tray on inside of freezer. Install new plastic line from water pump outlet to water fill tube, check for leaks, job done.

first I diagnosed the problem with the whirlpool do-it-yourself repair manual, which was very easy to understand. as per the repair manual, "this part located on the evaporator or the back of the liner is used during the defrost cycle. This bimetal senses the temperature from the evaporator. When the temperature reaches 50-70 degrees (F) ... Read more the defrost bimetal turnd the defrost heater off. " then I emptied the freezer. removed the the back panel to expose the evaporator. I looked for the bimetal defrost thermostat clipped on the evaporator. tested the bi-metal defrost thermostat, as per the manual, " the ohmmeter should show ZERO resistance (continuity). if not, the bimetal is bad and needs replacing." NOTE: the bimetal must be cold. it is also tested with the bimetal warm/hot, by running it under hot water. i used a styrofoam cup with hot water & dipped the bimetal in. as per the manual, " the ohmmeter should show an open circuit. if not, the bimetal is bad and needs replacing. then got online found partselect.com. ordered the part, recieved it in less than 2 days. within minutes after recieving the part, I removed the bimetal defrost thermostat and spliced in the new one. thanks to partselect.com my fridge is back up and running properly again. prior to installing the new bimetal, i tested it, as descibed above, you can hear & feel the bimetal open/close when it gets hot/cold.

Took all the screws out of the plastic shroud that encloses the switch .There only four that I needed to remove, were the two in front where the switches that go,they go in horizontally and two in the back with large washers on them that hold the back to the top of the box that go in vertically.The switch was a snap ( make that two snaps ...

OH! and don't forget to turn the light bulb all the way back in to the socket , so the light will work after you take the time to install it yourself.I had the water supply line from under the box to the water dispenser in the door and the total bill on that was one hundred thirty seven and a hand full of change.Don't be afraid to do it yourself the savings is enough on one one item to make several months payments on a new one Randy the "Handy Man'
