Timer "clicking", indicating worn gears

  • Customer: John from Plano TX
  • Difficulty: Easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Nutdriver, Pliers, Screw drivers
  • 20 of 24 people found this instruction helpful
1. Unplug refrigerator to remove power!
2. The timer is inside the control housing located at the top of the refrigerator compartment.
3. Remove two control knobs (the pull off).
4. Remove the front panel escutcheon. The panel is not held in place with screws, but can be gently pried off.
5. Remove two screws from the back that hold the housing in place.
6. Remove screws from the front that hold the housing in place.
7. Drop housing down (still attached by wires - do not detach). Timer is inside housing, located on right.
8. Follow the instructions provided to identify your particular wiring setup. You'll find the wiring diagram (on my model) at the bottom of the refrigerator, alongside the defrost catch pan, behind the airflow grille.
9. Remove connector from timer terminals (4).
10. Remove two screws/nuts that hold the timer in place.
11. Install replacement timer following included directions. Read and follow ALL instructions applicable to your particular model and wiring setup.
12. Reassemble by reversing the steps above.
13. Note: You may need to "jog" the replacement timer when you first plug the refrigerator back in, if the timer happens to be in a "defrost cycle" (the compressor won't start). This can be done by inserting a wide bladed screwdriver into the hole below the timer, aligning it with the timer shaft, and slightly turning the shaft CW. Don't force it, and don't turn it very far.

removed the three screw holding the broken unit - pulled off the old module.

Before I could install new module I had to loosen some fasteners on ice maker so I could turn shaft to align with new module.

Then push on new unit and three screws. Had tumbling ice in about an hour. My wife thinks I'm a hero. (I am)

ice would not fall from ice maker

  • 20 of 28 people found this instruction helpful
I ran all the ice maker module tests that I could find online, I tried cleaning the contacts inside the ice maker control module, nothing worked...so I finally decided to purchase a new control module. I had already had the module out and taken apart a few times, so the new one was very easy to install. Just removed the entire icemaker from the fridge, removed a few screws, took off the old module, put on the new one, replaced the screws, re-installed the icemaker in the fridge (it just slides in and out similar to a shelf). And 30 minutes later I heard the first batch of ice cubes drop! And by morning the bucket was nearly full. After two weeks of no ice and trying to fix it myself - the family was glad to have ice again (it was July in NC!). In retrospect, I should have followed the advice I found online and ordered the new part sooner and saved all of those frustrating hours of trying to "fix" the part myself.

Over flowing Icemaker

  • Difficulty: Really easy
  • Time to Complete: Less than 15 mins
  • Tools Required: Nutdriver

Ice Maker would seem like it was the valve was leaking and Ice would build up at the rear of tray.
After listening to it cycle, (drop ice and fill) valve would open up again about 20 minutes later.
Over flowed and iceberg would form at rear.
Replaced icemaker unit and works fine now.

Icemaker arm was broken

  • Difficulty: A Bit Difficult
  • Time to Complete: 30 - 60 mins

The tiny piece of plastic that holds the wire that shuts off the icemaker, broke early on with our fridge (after just a few months.) We superglued it, but last week it bit the dust for good.

Once I got this part, I removed the freezer door and trays, and pulled the icemaker out by removing 3 flathead screws and unplugging the cables. Laying in the freezer on the floor was a bit unconfortable, but not too bad.

Then I inspected the icemaker. There was no obvious way to remove the part without disassembling the front of the unit (where the motor is) to release the spindle and free the part, so I did that - 3 or 4 nuts was all that held it together. Once that was out, I removed the spindle, swapped out the part, and put it all back together and back in the freezer. Plugged it in and waited.

It took a while to start making ice. Like 5 hours. Now it's going pretty slow (much slower than before.) Haven't had time to look into it, but my suspicion is the rubber hose that feeds water into the icemaker is blocked with ice or kinked. In any case, we have ice now (but not a lot), and the unit shuts itself off properly. However, we went from having too much ice (thing never shut off) to too little (thing makes ice too slow), so I need to shoot for somewhere in the middle ;)

The black plastic or teflon coating on the ice mold was coming off in flakes and freezing in the ice cubes

I took out the ice collection box and auger to get access to the three screws holding the ice maker assembly against the left wall of the freezer. You can use a screwdriver or a nut driver. I then unpluged the assembly and wiggled it loose from the water fill tube. I assumed that unplugging the unit would disable the water valve but I put a plastic tub under the fill tube just in case. I studied the assembly on the kitchen table for a few minutes before I disasembled it. After removing a snapon plastick cover I removed three or four screws on the gearbox and was able to pull and wiggle the parts apart. The heater contacts have rubber O rings so you have to be firm pulling the mould out of and into the gearbox mount. Make sure it is fully seated. On reassembly note that the ice kicking arm is notched so it fits into the gearbox only one way and it helps to have it in position when you screw the gearbox back on. I also found the plastic ice guide that fits on top of the mold a little awkward in snaping back together. Make sure its fingers space evenly with the ice kicking arms.

Freezer was cold, refrigerator was not.

After noticing my freezer was ice cold and the refrigerator was luke warm, I figured there was an airflow problem due to either a fan that failed or the evaporator coil iced over. Just by opening the freezer door I could hear the fan blowing so it had to be the evap coil. Sure enough after removing a couple screws and the back panel I saw the ice. I then unplugged the frige to let it thaw overnight. In the morning I inspected the coil and luckily noticed right away that this little piece didn't look right. The top of the bi-metal thermostat was raised up. Almost like it popped. I read the other reviews on this website reffering to using an ohm meter to see if it held continuity. Well it didn't because the piece really did "pop". The wire was severed. So the ohm reader read open even if the piece was warm. I ordered the part and in days was able to replace the part. NOTE TO BUYER. It did not come with electrical connecting nuts or whatever they are called. So you'll have to go to the hardware store and pick some up for about $2. Frige works fine now. Thanks parts select.

The icemaker stopped filling the ice tray to make ice.

I checked the fuses and hoses in the back of the refrigerator to make sure water WAS in fact getting to the front of the fridge. Since the water through the front door worked fine, I had to check the water tube running to the ice maker. It was fine and water was waiting to go somewhere! I decided to pull the icemaker out of the fridge to see what I could fine. Once it was out, I took the ICEMAKER CONTROL AND MOTOR ASSEMBLY off (that's the side part with the dial on it). Only 3 screws to take that off, and it was EASY to see what was wrong once I took that off. There was a connection that was obviously bad (looked almost like it had burned out). My thought was that it was obvious what part was bad, what would it hurt for me to try to fix it myself? When I got online to find the part, PartSelect was the only one that I found that had the EXACT part that I needed, and lucky for me, there were multiple pictures of multiple angles of the part so I could compare and make sure I had the right one!! The part with shipping cost less than the cost of a repair tech to even come out and look at the fridge. Then add the cost of the part and labor if I had the repair tech fix it...I probably saved about $250!!!!

Defrost timer was faulty. Required a mild tap to restart

  • Customer: LES from MADERA CA
  • Difficulty: Really easy
  • Time to Complete: 30 - 60 mins

Trouble shot the electrical circuit per the electrical schematic and zeroed in when I noted the Defrost Timer circuit was open. When I tapped on the bottom of the timer it began functioning normally (for a few days). Ordered a new Defrost Timer Kit and along with the installation instruction, I watched the on-line video. It was very helpful!!
After installation was complete, I plugged the Refrigerator into the electrical outlet and.......nothing happened! Hmmm!

Removed the Defrost Time Kit and inspected it for any damage and found none. Then I placed a flathead screwdriver to the manual advance knob and slightly rotate the gear mechanism. I heard a distance "click”. I believe the Timer was in the ‘defrost’ mode when received.

I reinstalled the timer, verified the wiring connections and this time plugged the Refrigerator into the electrical outlet and ….. it worked!!!

I unplugged the refrigerator, finished the installation per the instructions, plugged the unit in and monitored it for a few hours (just in case). That was a week ago and the Refrigerator is working like new.

The instructions were written in a manner which required re-reading a few times as they could be a bit vague. The video was what really helped and I appreciate PartSelect adding it to the instructions.

Slow to produce ice & tray damage

  • Customer: Tim from Leander TX
  • Difficulty: Easy
  • Time to Complete: 30 - 60 mins
  • Tools Required: Nutdriver, Screw drivers
  • 14 of 17 people found this instruction helpful
Removed the top two screws and one on the bottom which attach the ice maker to the side of the freezer. I unclipped the wire bundle from the side of the ice maker and unplugged the connector, totally removing the unit . The maker came with several different wiring setups, but I just used the existing. The contol arm on the new unit basically snaps into place and the above process is reversed to install the new unit. My old ice maker had an accelerator which blows cold air to the bottom of the tray to speed up ice production. This component was undamaged and by taking off the new units outer end cap and borrowing the clips from the old unit, this component can be installed on the new ice maker.

ice maker did not make ice

The ice maker was not getting water. I hotwired the water valve by switching the connectors for the water dispenser and ice maker water valves and water flowed into the icemaker when the water dispenser lever was pushed. I wronly assumed the water valve was good. I removed the icemaker and determined that the gear motor was not getting power in the position the icemaker had stopped.In this position, the thermostat determines when the motor gets power so I replaced the thermostat. The icemaker still would not get water! As it turns out, the water solenoid was sticking due to a deteriorated rubber washer which let the solenoid plunger get too far out of the magnetic field. I replaced the water solenoid assy and all is well. Don't get fooled by hotwiring the valve. If it isn't getting water, the solenoid probably is the culprit.

Right front wheel broke

Definatly a two man job. I suggest you put a pad down to protect your floor. Remove the filter, grill, and bolts per instructions. Everything is straight forward. Move the frame back 1/2 to 1 inch then tilt the frig back on it's side about 4 inches. If the frame doesn't drop down, move it back until the front of the frame comes of the front lip of the frig. Place a block under the frig lip NOT the frame and WATCH YOUR FINGERS. The wheel should be hanging down. Just pull out the pin, replace the wheel (make sure you have it facing the correct way) and tilt back and pull the blocks. Move the frig back in place and replace the bolts. Took me and a buddy less than 30 minutes.

ridiculous how a tiny plastic broken part required a full motor assembly replacement. that being said, i went online, found this website and easily identified the part i needed to order. i was impressed when it arrived within a couple of days. removing the old motor and replacing the new was a piece of cake...and i am NOT mechanically inclined,
