Wish I was in the refrigeration class right now, but working on fundamentals.
Don't know how much stuff you DONT want to read about in my OP. So Here goes the long enough story.
HO sets appointment because of no ice. She don't have model # she could not see number, so I couldn't pre-diagnose, so I went out completely blind (to say the least) never saw this machine before. Did not bother to find tech sheet on HO time. Ask HO if it was ok for me to study a little and come back on Monday (it was Thursday) she said yes. I called her on Friday and ask her if I could work on the refrigerator on a "my cost for part repair". No labor or markup for part. Knowledge is priceless right, I do this sometimes so I will have a better understanding of the machine at hand to learn from and take my time and not rush, HO saves money now, I'll make money later. its because I'm a hands on person books alone are hard for me.
Found Job Aid and some service bulletins on here so I read it off and on this weekend and got a beginning of a game plan, you know, to run display for a good and hopefully complete diagnostic tests. I have no parts I can take so I knew this would not be a Second Call Complete today.
1) take a quick temp of RC, FC and ice box are. RC=39 deg. / FC= -7 deg. / ice box=49 deg.
I felt no air out of ice box, but DID fill RC fan, forgot to listen for FC.
2) no water in ice maker,
3) made the following diagnostic test in this order.
#1=FC thermistor /// 01 pass
#2=RC thermistor /// 01 pass
#3=evap fan and air baffle /// all three fans worked separate and together (RC and FC)
#58=ice maker heater activation and thermistor
a. heater /// 0=heater off
b. thermistor /// 0=temp warmer than harvest temp
#36=ice box fan /// fan pushes air out
#37=ice box thermistor /// 01 pass
#56=ice maker error codes /// E2=motor lost position ( must not be turning right?)
#57=ice maker harvest /// 02 comes up = 0, heater and motor off 2, harvest not complete doors must be closed. (is that telling me to do this test with doors close or does it think the door/doors open.
#59=ice maker motor
a. 10 = 1, motor rotating C.W. 0, in progress
after about 1-2 minutes it pops up this
b. 02 = 0 motor off 2, harvesting not complete
#45=ice maker water fill test /// 03=on (water went into ice maker, 04=pause
Took out of diagnostics, FC fan started and so did RC fan but not ice box fan ( but its in a motor lost position error) so don't know if that would interfere with ice box fan in normal running stage.
Did not want to waist HO time any further for today so I informed HO of my findings so far and told them I would call them in the morning and if this was OK with them and they said yes.
Came home to study some more about refrigerator.
Now I see I maybe should have did #15=ice level sensor
#16=RC door switch input
#17=FC door switch input
should I have tested P7-5 to P7-6 for 14dc at board (connected or not)
and P7-3 to P7-4 for continuity at board for switch (what switch)
I did not see any service bulletins about air supply duck freezing shut as to prevent air flow per maybe air leaking into ice den compartment.
So I wonder if this conclusion is right so far.
I.M itself is stuck in middle of cycle and wont turn anymore causing fan not to run and temps to be hot in ice box ice maker #W10498261 sub to W10764668
air supply duck frozen
I would like to take what I think I might need, for me, for now I think I.M.
I would love to make it a third call complete.
Don't know what else to add been studying and writing for hours and getting tired.
Any thoughts or suggestion, let them fly please.
Sorry so long.
Thanks so much.
P.S. didn't try to take anything apart today until I get a better understanding of machine don't want to be a blundering idiot opening/breaking something I may not have to open/break until I understand it a little more.
I wish Whirlpool still had the tech line I could join and call for help I paid last year and didn't use it that much and now they don't offer it to independences, any thoughs or suggestions on this also.
