CST20KABBWH Hotpoint Refrigerator - Instructions

Fridge was not really cold. Fan was working at back of freezer. Romoved the drawers and back panel of freezer compartment. Melted ice with a blow dryer and collected water with a towel so that it would not overflow the drip pan. Installed the new defroster units with 4 screws and the easy plug in wiring harness. Bingo! Defrost timer was probably OK but new one is easy to do.

Fixed in one day vs waiting for service call & payng $$$.

Per the trouble shooting guide on the home page of the website. I suspected the defrost timer was bad because ice had heavily accumulated on the back wall of the freezer compartment and the temperature inside the refrigerator was warm. First, I removed all the freezer racks. Then removed the (4) screws on the back wall in the freezer compartment. I then removed the ben from the ice maker to allow more room. Once I saw all the ice, I unplugged the refrigerator, and used a hair dryer to defrost ( it took about an hour to get it all). Once the ice was all gone, I then moved into the refrigerator compartment and removed the top shelve. This allowed me more room and access to the defrost timer which was behind the back panel. I used the trouble shooting guide to test the old timer prior to removing the new one from the package, (just in case I needed to send it back). Through this test I determined that the timer was bad, it wasn't the heating element or the t-stat. It was very easy to access, I removed the two knobs and lifted up the panel. I located the defrost timer and removed the screws as directed. I replaced the timer just as I had removed it, plugging in the electrical terminals per the removal process. I then reversed the order and put the panel and top shelve back on. Once all complete, I then moved back into the freezer compartment and replace the back panel and then the ice ben. I plugged it in and haven't had a problem since. This site has saved me a tremendous amount of money, a service contractor quoted us $300, to determine the problem. I ordered the part and it was sitting on our door stoop the next morning.

I applied some tips learned by reading other reviews. So before I started I grabbed my trusty vise grip pliers and a small screw driver. I locked onto the switch actuator, the part that the refrigerator door pushes in, with the vise grips and pulled on it just hard enough to get the screw driver inserted in the right side to push in the catch clip so the switch could be pulled out further each time the catch clip was depressed to the next detent. Then I used the screw driver on the left site to encourage the switch past the detents on the left and very quickly the switch was out of the mount. The wires from the refrigerator pulled out with the old switch. I unplugged the old switch from the wires and plugged in the new switch and shoved the new switch back into the mount, wiggled it a couple of times to make sure it was secure and the job was done. Once I applied the vise gripes at first, the whole job took less than a minute.

Disconnected the power to the refrigerator/freezer. Removed the shelving in the freezer. Had to remove the light cover (1 screw in center top of light, slide to left and cover is removed) located in the top of freezer to obtain access to the screw in the back panel. Removed the back panel (using nut driver). Four screws (2 at the top and 2 at the bottom). Used a heat gun to defrost the coils enough to remove the screws and wiring harness. I started at the bottom unit by removing 2 screws with a #2 phillip screwdriver to remove the lower defrosting element. Carefully pulling the wiring forward from the sides of the cooling coils until I reached the next defrost coil. Repeat removing 2 screws to remove the next defrost element. Continue to carefully pull wiring harness toward yourself. Remove the Thermostat (just clipped on the upper left side of coil. Remove the plug. Carefully reverse the process to complete the process.

Our refrigerator is a double door unit with ice and water in the left door. The right door was the one with the problem. It was 5:15 AM when the problem occured. I could see that the door was out of alighnment and had dropped down - preventing it from closing. I lifted the door and closed it. I wrote down the model number and found a detailed drawing of the appliance on the web site "partselect.com". When the hing earrived I compared it to the broken one. I removed all the food stored on the door, put several pieces of wood under the door to shim it to the same height as the adjacent door. I then removed two bolts from the refrigerator with a 1/4" socket set. I put the shim from the old hing aside for later. I removed two bolts from the door with the same socket -Note a metal tab had to be bent silghtly so the wrench could go on the head of the bolt- I removed the plastic cam and made note of its orientation and that of the shim above it on the door. I put the shim and new cam in place on the door and installed the 2 bolts. I inserted the pin of the new hing into the hole in the cam (I had just mounted) on the door. I put the shim (the one put aside earlyer) behind the hing and replaced the two bolts. I held the shim and hing up against the door as I tightened the two bolts. When I was satisfied that the bolts were tight I removed the wooden blocks that were holding the door up so the door was supported by the new bottom hing assembly. The door now opperates perfectly and the refrigerator was not taken out of service for the repair. Total time including cleanup was a little over 15 minutes.

Removed back panel. Opened cover to relay attached to the compressor and pulled off replacing with new relay. No problem.

Better than paying $250 for someone else to do it.

I removed the back panel held in place by 5 screws. I located the thermostat and disconnected it from the wire connection to another part. Due to the connection requirement, I had to cut the wires from the original part and splice the connector with wires to the new part. After securing the spliced wires and covering in electrical tape, I replaced the panel and all screws.

Removed 2 phillips head screws to remove ice maker (could have just loosened them)
Pulled fan off of shaft
Removed 2 phillips head screws on motor bracket , disconnected three motor wires & removed motor.
reversed process to install new motor & fan blade.
Space was a little tight for two hand and arms, but do-able.

Had to use a hair dryer to manually defrost the refrigerator before I could replace the heater assembly . I had to remove the aluminum mounting brackets and reverse them before mounting the assembly so that the wiring would run the same as the old assembly . Overall time spent from start to finish, including manual defrost was about 2 hours.
Thanks for the timer troubleshooting tips, they helped to narrow down the problem.

Troubleshooting was easy - others had the same problem - coils freeze over and frost blocks air flow to refrigerator - part identification made easier by online picture - many parts look the same so you may want to call and confirm before you order (there were variations to this model number) - To repair: take off five screws that hold the metal panel on the back of the freezer - remove the panel - use a heat gun or hair dryer to melt ice from the coils (put a towel at the bottom to soak up the water) - unplug the kit at the top of the freezer and carefully pull off the thermostat clipped to the coil - remove the four screws that hold the heater kit to the back of the freezer - install the new kit where the old one was then re-install the panel to the back of the freezer - next, make time to clean the condenser coils under the refrigerator/freezer

Couldn't find schematic or repair manual
Finally found your site which showed the location and part numbers of the timer and heaters.
I ordered them; they came immediately.
I replaced only the timer, since it was the easiest and took only a few minutes. Defrosting the frezer coils with a hair dryer took about an hour.
Rerigerator froze over again in about two weeks.
I then replaced the heaters. One of the heaters was 'open circuit'.

First, I made a mistake. I took all the screws out and removed the gasket. This allowed the door tray to drop loose. Then, I realized that wasn't the way to go. So I remounted the door tray and the metal gasket supports but left the screws loose. Then, starting at the top, I worked the new gasket in behind the metal supports and tightened the screws along the way. I completed the installation by following this same method down the sides and at the bottom.

This is a sibe-by-side refrigerator/freezer that needed a new lower hinge set for the fridge door.

First I removed everything from inside the fridge door, closed it, then loosened the top hinge bolts with an 8mm socket on a 1/4-inch ratchet. Using an 8mm nutdriver, I removed one bolt and loosed the other just far enough to be able to lift the hinge and swing it out of the way. (These bolts are long. The nutdriver is faster than the ratchet but you need a ratchet or a wrench to first break them loose.) Then I just lifted the door off the bottom hinge and set it aside.

The plastic lower front grill was covering the lower hinge but that grill is just held at the ends by spring clamps -- popped off easily so I could get to the hinge bolts. Again, 8mm bolts, just remove & replace hinge. I also had to replace the upper half of the door closer cam, which is screwed to the bottom of the door, being careful that the holes lined up: cam, shim, door holes.

Now the tricky part was lifitng the door back on the lower hinge. (It helps to have an assistant at the bottom to locate the hole for you.) Once the door was up, I swung the top hinge over, ran the two bolts in finger tight with my nutdriver, checked & adjusted the spacing* of the fridge door and tightened the bolts. This was all very easy! (*^_^*)

*On a side-by-side, you'll want the door to be straight up & down with a consistent gap top to bottom with the freezer door. The hinge has some slack for adjustment by positioning the door, then tightening the bolts. You'll see what I mean.

1. Unplug, remove control knob from both temp control sliders, remove upper light bulb and light shield from refrigerator compartment. 2. Remove screw holding top of bracket control mod in place. 3. Lift bottom tab from slot and remove control mod from ref compartment. 3. Unplug temperature control and defrost timer and replace. (Each are held in place with two screws.) 4. Replace control mod. This part took me the longest because the space between the top of the control mod and the top of the ref. compartment is very small and replacing the nut was difficult. Use a nut driver with a long shaft. 5. Use screw driver to turn control button of defrost timer to start cycle. 6. Replace bulb cover and light bulb. 7. Set temp control to initial setting. 8. Have a Margarita and celebrate. It's been over a week and the refrigerator/freezer is working perfectly.

First unplug the refrigerator!

Removed the top shelf of the refrigerator. Pulled off the knobs from the temp slider controls. Popped the cover off of the light and temp control section. This Hotpoint model has both
thermostat and defrost timer easily accessible in the refrigerator compartment. Used a socket set
driver to loosen the screws and remove the
temp control section and unplugged the wire connectors. This freed the whole temp control
section. On the workbench removed the old
thermostat by unscrewing the screws with a socket driver. Unplugged the wires from the old thermostat then put the new one in. Then put the
new one in the same holes, reconnected the
wires and reassembled the everything. Then
simply put this temp control box back in the
original place (and reconnect the wire plugs)
and put the screws back in . The hardest part is re-aligning the holes and the control levers, but this is not too bad.

Plugged it back in and so far it has been turning
on and off normally. (The old thermostat contacts
were oxidized so I think this was the problem).
