Frigidaire #FRS26ZGE - No Ice
I had to repair my ice maker for the same symptoms. Either no-fill or inadequate fill. The problem was the timer motor contacts for the solenoid were burnt and corroded. Crappy design reminiscent of failure prone washer machine timers. Anyway, the problem was very obvious as soon as the face of the icemaker was removed. I cleaned up the contacts and used some epoxy to fill in where the surrounding plastic melted. Been working for 4 years since that repair. One other warning: Unplug the fridge before you remove or work on the icemaker. There is 120 volts on the internals and the connector (which may or may not be adequetly protected against prying hands). -Chris |

Frigidaire #FRS26ZGE - No Ice
Chris,
Thanks for the precaution. Yes, the schematic clearly shows the 120VAC is in the ice maker. My design must be slightly different since the motor turns a small plastic gear which turns a larger gear which has a cam with a raised lobes that activate the three microswitches referenced in my previous posting. I did remove the face plate and did a quick check of the 3 microswitches with the power off and an ohmmeter and they all seemed to work fine when depressed with my finger. As I also noted the motor appears to be turning. It appears to turn fairly quickly (equivalent to maybe a revolution in about 4 or 5 minutes) for the portion of the cycle when the ice gets ejected from the mold and then slows down for the remaining half cycle or so. This leads me to believe it is working properly. I just need to get more time when the unit is less full to troubleshoot the ice mold heater and thermostat. Thanks again to all for the assistance. I'm certain this will get solved, I just need to get the time and empty the unit more to work in there. Bob wrote in message ... I had to repair my ice maker for the same symptoms.

Frigidaire #FRS26ZGE - No Ice
Just wanted to report back that I finally was able to get this ice maker
fixed. After considerable time diagnosing (all the individual parts appeared to work as designed), I determined that the problem was in the wiring harness cable connector to the ice maker water solenoid valve. The good news is that no parts were needed. The bad news was that it was the last thing I had expected to be the root cause. I ended up having to pull out the refrigerator and take the back off to access the solenoids on three different occasions. I also had the icemaker apart on 3 separate occasions as well and finally ended up pulling it completely to validate on my bench that it was working perfectly. Oh well, live and learn. I'm glad to have it working again. Thanks to everyone for the advice. Bob wrote in message ... On Fri, 11 Jul 2003 17:11:46 -0500, "Bob Shuman" wrote: Chris, Thanks for the precaution.
