4ED20ZKXBW00 Whirlpool Refrigerator - Instructions

Compressor start relay would cycle several times before compressor would come on. Replaced start relay and defrost timer assy. Operated more consistently however not completely reliable. Ice would begin to melt. Noticed that if you would cycle the temperature control the compressor would start again and operate for several hours then not cycle again. Jumpered temp control and operation was continuous and reliable. Replaced cold control thermostat. Operation now normal. Suspect high resistance in switch caused start relay and timer contacts to arc. Small amount of carbon noticed under temp control...

WARNING: REPLACING THIS PART REQUIRES CUTTING AND SPLICING ELECTRICAL WIRES. RISK OF ELECTRICAL SHOCK OR FIRE. DO NOT ATTEMPT THIS REPAIR IF YOU ARE NOT EXPERIENCED WITH ELECTRICAL WIRING.

Part Info:
The bi-metal strip is clipped onto the evaporator coils and is designed to regulate the defrost coil temperature. If it is not functioning properly you may notice ice buildup preventing air flow (and preventing proper refrigeration), or more rarely the freezer side may get too warm during the defrost cycle.

Materials:
* Replacement bi-metal strip
* Wire cutters
* Wire strippers
* Wire nuts
* Electrical tape
* 10MM socket

Steps:

1: UNPLUG THE FRIDGE! If there is ice buildup, wait until the ice has melted. A box fan blowing at the ice will help melt it more quickly.

2: Remove the panel covering the evaporator coils. It's located inside the fridge, on the freezer side.

3: Un-clip the bi-metal strip from the evaporator coils.

4: Unplug the wires from the evaporator fan, defrost coil and bi-metal strip, then disconnect the main connector that is plugged into the rear wall.

5: Clip both wires to the old ( bad ) bi-metal strip. Cut close to the casing of the bi-metal strip so there are long wires to splice onto.

6: Strip 1/4 to 1/2 inches of insulation off of the ends of the wires ( depending on the size of the wire-nuts you use). Twist the bare wires slightly to prevent fraying.

7: Do the same for the ends of the wires on the (new) bi-metal strip.

8: Take the ends of the wires belonging to the (new) bi-metal strip and the wires coming from the main plug. Take the like-colored wires, and twist the bare metal ends together.

9: Twist on wire nuts, for both sets of wires. Make sure they are snug, with no bare wire showing.

10: Tape over the wire nuts with electrical tape. Tape over the wires nuts in a spiral fashion, completely covering the nut and both wires that are now spliced together. This will prevent accidental shorting.

11: Plug the main plug back into the rear wall of the fridge. Also re-connect the connectors to the evaporator fan and defrost coil. Make sure the clips on the connectors are snug to ensure a good connection.

12: Clip the new bi-metal strip onto the coils, in the same spot as before. ( Usually just after the small incoming copper tubing that connects to the coils, known as the expansion valve. That is usually the coldest spot on the coils during operation).

13: Replace the panel that covers the coils.

14: Plug the fridge back in... Now you fridge should defrost correctly. If it does not, your defrost coil could be burned out, or the control board could be faulty.

The repair was very simple.

1. Remove the food from the door shelves.

2.Remove the door by first removing the three screws holding the hinge at the top of the refrigerator.

3. Lift door off of the bottom hinge.

4.Replace bottom CAM on bottom hinge (one screw)

5. Replace top CAM and shim on door (one screw)

6. I put a little grease on the cam to make it slide better.

7. Place door on bottom hinge. Remount top hinge.

8. Done and works better than new.

Was pretty simple just take the knobs off pull off the face plate remove a few screws and drop the whole shelf down. then a few more screws down the side to the back of the fridge. Pull the sensor wire out of some styrofoam and pull off the plastic coating and slide it over the new one and install it in reverse order from taking it out. Works great now and i have ice everyday :)

I removed both plastic knobs from assembly faceplate. Then I loosened the screws holding thermostat housing to upper cabinet of fridge. Following this step, I loosened the screws of the thermostat to remove it. Next was the removal of the plate and vent pieces holding the thermostat wire sleeve in place. After removal of thermostat from sleeve; all steps were reversed and unit was up and running normal (cooling) with no problems. "Ahh, it's nice to have cool again "

The hardest part was to figure out how to remove the old studs and put in new ones. I figured out finally that they should be twisted out and in., Simple online or printed insruction would be very helpful. Unfortunatelly the manual does not contain any repair information.
I fixed it with little trouble.

First I removed the old lightbulb from the socket and replaced it with a new one to confirm that the bulb was not the problem. I then pryed the socket out with a flat-head screwdriver. I could tell that the socket was anchored in its hole with clips so it was relatively easy to pry it out. Once the socket was out, I disconnected the lead wires and ordered a replacement socket kit from Partselect. When the new one arrived, I reconnected the lead wires to it, snapped it back into its hole, screwed in a new lightbulb, and presto!! The light was back on with no further problem. Thank you, Partselect!! A $15.00 part saved me what probably would have been at least a $100. service call and heaven knows what the technician would have told me I needed!!!

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 ) the wiring is almost self explanatory. then it gos back to the way you took it off. 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'

First I removed the cover plate over the cover over the thermostat, by snapping it out. Then I removed the four screws holding the cover over the thermostat in place. Next I removed the screw, which held the cover over the thermostat sensor. I then removed that cover and the unit, which exchanges air, flow between freezer and refrigerator. I then removed the two screws, which held the thermostat in place. I then removed the thermostat with the sensor and the white tube, which covered it. Then I removed the white tube from the sensor.

To install the new thermostat I first inserted the thermostat sensor into the white tub. I lubricated the sensor with a very small dab of Vaseline. Then I placed the sensor unit in the unit, which exchanges air between refrigerator and freezer. I next reinstalled the unit, which exchanges air between refrigerator and freezer. Then I reinstalled the cover over the thermostat sensor. I then installed the thermostat with the two screws, which held it in place. Then I reinstalled the cover the thermostat with the four screws, which held it in place. Last I snapped the cover plate in place.

After removing all the food items from the door, I popped the plastic cover off of the hinge assembly located on the top of the door. With a fine point Sharpie pen , I marked the outline of around the hinge assembly so I could return it to original position. I then loosened each of the 3 bolts holding the hinge on just enough to allow me to clear the pin of the hinge out of the hole in the door. Once the top was free of the hinge, I lifted the door off of the bottom hinge/pin assembly. My cam parts on the bottom hinge and door were either broken and/or partially missing. I removed the broken and worn pieces by removing each of the screws holding the top and bottom (of the bottom hinge assembly) cam pieces and installed the new ones using same screws. I then reversed the steps and slid the bottom of the door back onto the bottom hinge assembly and then lifted the top hinge enough to allow the hinge pin to slid back into the hole on top of the door. Positioned the hinge so it matched the outline and tightened the 3 bolts. I checked the closing and made a slight adjustment to door as one of the shelves was hitting the interior as it tried to close. I did this by loosening the 3 bolts and pushing the door up and to the right (this door was on the right side of refrigerator). Tightened the bolts and reinstalled the hinge cover.
Pretty easy. My door cams were a little different so I didn't use all the parts in the kit. My shims were metal and did not move when I replace the cams so I didn't use anything in this repair except the 2 lower cam parts. I also put some grease/vaseline on the cams to lubricate them.
I figure the plastic cams just wore out over the years and all the heavy junk we put in the door shelves. I lived with this problem about 2 years before it donned on me that it was probably just a plastic piece or two that was broken or worn out.

This product comes in a bottle with a brush like Liquid Paper. It goes on incredibly easy. A second coat might be needed. I wanted to prevent rust from setting in so I covered the scratches and dings. The paint is a little brighter since my washer is 10 years old but it still looks great.

I have a side by side so in order to access the bi-metal switch I first had to empty out the freezer. The switch is clipped on to the top of the evaporator coil. I had to remove 8 screws to remove the back panel of the freezer compartment. The bi-metal switch was right there in plain view. There are two colored wires that come out of the switch. I tried pulling them out of the socket they were plugged into but gave up for fear of breaking something. I ended up cutting the wires and splicing them together. I used the plastic twist caps. I made sure when I closed everything back up that the open end of the caps were pointing down so no water can accumulate in them. It has been 3 days now and so far so good

DISCONNECT POWER. Removed all shelves/baskets.Popped upper panel off (just clips in) Removed 6 screws in lower back panel ( 3 each side) slid panel in place but down. You can then easily see the defrost thermostat/defrost termination switch. Cut the wire connectors (pink n brown wire) stripped back wire, attached new defrost thermostat. Thermostat clips on. New thermostat ohm's at 5.5, old one was "open". Slid cover back up meeting the upper cover grooves. Screwed lower panel in. Put shelves etc back in. Plugged in. Turns on, put a bottle of water in freezer. Checked a while later, frozen. has been frozen for a week.

I loosen the screws with a nut driver just enough to pull old gasket away from door. This way the door panel and gasket retainer stay in place. I placed gasket from top and worked my way down one side. It took a little more time to slip gasket under retainer evenly, tighten each screw to keep gasket from pulling out while working around door.
30 minuets tops,never had to turn off refrigerator.

While moving our refrigerator when remodeling the kitchen, the front roller assembly shattered from age. The original set was made of nylon and age made it very fragile. Also to make the move easier, we removed the shelves. In the process the lower shelf support stud snapped.

When the parts came the first thing repaired was the shelve support stud. Very easy job to do, just take the pliers and rotate the broken stud counterclockwise a quarter turn and remove. Put new stud in the hole in the same position as the removed stud and gently, but firmly rotate the stud a quarter turn clockwise until it seats.

The front roller assembly requires a socket set, block of wood about 1/2 - 1" thick flashlight and 4’ level. First, remove the front grill by opening both doors of the side by side and pulling the grill out of its left and right side anchors. Close the doors. Place the block of wood under the front support near the center. Remove the leveling screw from the old assembly and install it loosely in the new assembly as the new assembly has no leveling screw. This will now allow you to remove the old assembly by removing the remaining screw in the roller assembly on the front refrigerator support and turning the roller assembly slightly counterclockwise and pulling out the front. You may have to wiggle it, as it sits in a slot on the side support of the refrigerator. To install, place the new assembly in the same position as the old, locate the slot with the flashlight and push the roller set tab into the slot. Attach the support screw and tighten while holding the assembly in place. It is a good idea to replace both rollers at the same time. The same rollers will fit both sides. Now level the refrigerator by tightening the leveling screw until the front rollers now touch the floor. Next, place the level on the top of the refrigerator diagonally but not on top of the door supports. Turn the leveling screws until the bubble is in the center when the level is set in either diagonal position. Replace grill and you done.
