Oh Great and Learned Ones...

Circa 2001 SZ 650 u/l.  No ice, Ice Service indicator flashing.  Ice Maker switch activates audible relay. Where do I begn my journey?

Nothing mechanical/electrical scares me. :ninja:

 

I beg you share your wisdom with this lowly one...  I am prepared to reward knowledge with fresh home roasted coffee.

I'd start right down at the water inlet valve. Ohm out the coil and see if it has continuity. Next test would be to manually cycle the icemaker and test for 120vac at the power wires to the water inlet solenoid.

Sounds good.  What do I do to manually cycle the im?

No ice will soon be the least of your problems if I am projecting far enough. On a 650 of this era, a flashing display panel indicates excessive compressor runtime. Check to see if the condenser is clean. I'll bet the condenser fan is running all the time, even when the compressors are off. If you turn the unit off and then back on the flashing will stop but it will most likely return. You'll have to dig further into it. I'd want to get a look at the ref evap after it has been running for a while and a ref compressor amp draw test will reveal much without putting gauges on the ref system.

There is a switch near the ice bin that must be closed (physically and electrically) for the i/m to work, see if it has power coming into it and going out of it. There could be two different types of i/m in there so there would be two ways to force them to cycle. Post a pic if you can or pop the front cover of the i/m off and tell us what you see.

Is the unit holding the set temps?

Hi AccApp,

Arghhhhhhhhh.....  Stop scaring me! :yikes:

Yes, everything is clean.  Twice a year it gets vacuumed with my trusty shop vac.  Cleanliness = lower energy costs and longer life.  I was up top 2 nights back and don't recall seeing/hearing the fans running but I will double check this tonight.

I've seen a couple of mentions about switches near the im but haven't seen them.  This is an upper lower 650.  Any ideas for the location of said switches?

The entire unit holds set temps with no problem. I will try the power down/power up to see if the light resets and I will let you know the results

Should I remove the freezer door in order to get best access to the im?  If so, any hints/warnings to follow? I will photo and post pics today/tomorrow.

Is there a service manual available on-line or as a pdf?

Thanks for everything.

Don't remove the freezer door, you can easily remove the whole freezer drawer quite easily by pulling it out and lifting it up, forward and out. Then you'll see the switch thta gets closed by the ice bin to activate the i/m. There will also be two others, one to activate the light and one to turn off the fr evap fan when the drawer opens.

PM your email address and I'll be happy to send you a very vague, general service manual.

So I cycled the unit off and on.  The flashing im service alert goes away and about 20 minutes later the im drops a load.  We go out for dinner and this morning the ice bin is pretty full (2/3).  I've emptied the ice bin and will see if it makes more.

Hmmmmmmmmmmmmmmmmmmmmmmmm  :?
