This is bottom drawer type frige. Icemaker is inside (not in the door) and hard to reach. I first tested the solenoids by disconnecting them and using a test cord, energized them independent of the frige wiring. They worked ok. Note: this frige has (2) solenoids going to the icemaker. And it has (3) solenoids serving the water disp ... Read more enser. The icemaker solenoids are wired in parallel. I removed the icemaker by removing (1) screw from the bottom and loosening (2) on the top. Then removed icemaker as a complete unit disconnecting the wire connector at the same time. On the bench I tested the icemaker to verify it was defective. The wire harness has a 10 amp fuse in the black wire (hot wire). `The fuse was blown. This was sufficient to indicate the icemaker is shot. I did however, do some other tests. Cold resistance of the mold heater was 72 ohms. The timer motor was 4000 ohms. These measurements should be ok. I then activated the icemaker with a test cord, bypassing the blown fuse. The unit cycled one complete rotation then stopped. The mold heater worked. I tested the amp draw on the mold heater and it was only .1 amps. I should be a about .8 amps. I then cycled it again and then the timer motor began to sizzle and smell. Then it smoked and stopped mid-rotation. I then purchased a new icemaker. I believe the mold heater was going bad over time as this unit made ice but very slowly. This put extra strain on the motor as the mold was not releasing quickly. This damaged the motor causing it to fail.

Went on line to see how difficult it would be to replace the valve. Through Google there was a video which showed in exact detail how to remove and replace the valve. Then went on line to find the replacement part which was readily available. The only problem was that the connection on the valve where the fill water enters the valve was l ... Read more arger than the old valve. To fix that I went to a local Ace hardware store and found a nut that would fit the valve connection. Also don't forget to use a compression ring to keep the fill line secured when replaced.
Over all it was very simple and was in my "pay grade"

In plug refrigerator. Pry old switch out with flat blade screwdriver. Disconnect wiring from old switch and plug into new switch. Push back into refrigerator. Plug unit back in. Lights and fan should now work. Check for cold air coming out in freezer.
