icemaker stopped working

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 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.

Like the customer who put a review on your site before me, I was unable to complete the repair because the inlet tube did not fit my refrigerator. I was hoping to speak to someone regarding this issue.

The past I ordered was broken upon delivery. I asked for a replacement and was refunded the charge. Tried to contact you but "due to covid" you aren't taking calls. Net result: I ordered the part from another source, got it, installed easily. Won't use you again.

Broken plastic/glass

Now that you have to buy a complete assembly that includes the drawer in the classy window it's very simple to replace however you buying parts that you don't need simply because G no longer makes the window. Which I find rather odd being as though that they make the whole assembly think and sell windows by themselves for less than 2/3 of what I spent through the whole assembly

Broken door gasket retainer

Go to this site on You Tube to watch the "how to" replace the gasket retainer. The retainer I needed did not come with brackets or the cam you will need. You will need transfer them from the old retainer to the new one. Not hard, just be mindful of position of the items you remove to put them back in place the same way. A metal rod holds the brackets and spring in place with a screw on one end to prevent rod from sliding off retainer. The cam has a screw that holds it in place, use from old retainer. If the old cam is not broken use the one from the old retainer. It is not hard and you will save $$$ that you would pay an appliance repair company.

Right door cam broken
1 of 2 people found this instruction helpful.
  • Gary from Goose Creek, SC

Remove door seal and cam shaft (one piece). Remove broken cam by removing Philips head screw. Replace broken cam with new cam and reassemble. The actual repair took about 15 minutes however the majority of time was spent figuring out that the door seal and cam shaft had to be removed, no tools required.

unfortunately my fridge stopped working. I purchased another but wanted to try and repair the old one. when ew one arrived, the old one was supposed to be put in garage but instead was hauled away. Had delivery return next day but they had as already removed and lost the handle screw for the bottom freezer and the screw that holds handle in place. ordered the handle screw and picked up the nut. very simple to install the screw and put handle back on.
