How to Troubleshoot & Replace Whirlpool AP6016623 / WPW10190929 Ice Mold

Ordered all moving parts, received them quickly and rebuilt ice maker. Installed ice maker and within 8 hours it was making ice. 

It was a relatively easy fix and the video instructions on this site provided were helpful. The one piece that wasn't clear is the alumilastic was already on the replacement part so a separate tube is not required. That wasn't clear on the video and was an unneeded expense. 

After reading other owners' experiences, I learned that the leak in my icemaker was due to an old and disintegrating Ice Mold. I watched the video, order the part and replaced the Ice mold and my ice maker is back in business and NO LEAKS!! Yah. Thanks all saved me tons of money. 

Replaced mold and drum. Trivial task for all - basic screwdriver skills, quick, accessible, and easy. Note that the thermal compound is provided already on the ice mold in current parts, and that you do *NOT* need to order the very expensive tube of Alumelastic cement (and mine will be going back!). 

Found the repair guide online & tested per instructions, which indicated a bad thermostat and/or motor. Bought motor unit first and installed. Amazing how easy these are to work on yourself compared to the cost of having a tech do it. Motor unit delivered & starting getting ice but VERY slowly. Since replacing the thermostat is a wee bit more complicated, but now experienced, ordered same together with ice tray which was in bad shape (the tray is coated with a plastic which was disintegrating). Changed out both in about 20 minutes, and all works beautifully now...lots of ice! 

Disassembled unit and after watching some service videos, determined that defrost thermostat was defective. The mold was also flaking off, so I ordered a new mold, defrost thermostat and the Alumilastic Cement to assure thermal contact between thermostat and mold. Parts came quickly and I transferred all components to the new mold. Reinstalled ice maker and it is now generating fresh clean ice! 

Replaced the ice tray and motor mount plate. While I was there I replaced the thermostat also. New parts arrived in a day and a half. 

The ice maker would make ice, but somehow it would occasionally leak. I considered replacing the whole unit but since the ice mold was full of hard water residue and it originally was a used unit, I thought I'd replace the ice mold. I did drop the unit taking it out so I also needed the fill cup as it broke. Repair went smoothly although I wasn't sure it worked until the next day when the ice was successfully made. 

The ice maker 'ice mold' tray had it's slick surface coating peeling away. There was a lot of peeling - it was bad. Although I couldn't see in to verify what was truly happening, the thought was that the peeling was somehow diverting the water out of the tray, causing it to leak and form an icicle into the ice bin. Even if this wasn't the fix for the icicle, the ice mold still needed replacing because of the coating contaminants in the ice cubes. I disassembled the ice maker, replaced the ice mold, and now it works perfectly. No icicle. 

Replaced the: Icemaker Motor Module, Ice Mold, and Cycling Thermostat Video helped speed up the process.
