tl;dr: What does it mean when both tests 51C (Th1 mold thermistor test) and 54C (mold heater test) are failing with code "SH", both with and without the mold wiring harness plugged in?
I've had luck fixing the obnoxious ice maker in my Electrolux EW23BC71IS6 a couple times in the past, when the problem was with the Th3 thermistor (test 52C failing).
Now I have a new problem, and I'm hoping someone has some insight.
Here's what I'm seeing:
- The mold moves to the right, fills, moves to the left, freezes, then stays there.
- All tests pass, except for 51C (Th1 mold thermistor test) and 54C (mold heater test), which both display a code of "SH".
- With the mold wiring harness (green and white wiring) unplugged, 51C and 54C both still report "SH".
The "Fresh Food Icemaker Diagnostic" chart I'm using doesn't list "SH" as a potential code, but I assume it means "shorted."
So, I was hoping/expecting that unplugging the mold wiring harness would change the result of test 51C (Th1 mold thermistor) to either "OP" (open) or "Er" (error).
But it didn't change anything, so now I'm concerned it might be a wiring or control board issue upstream of there, which leaves me really unexcited about sinking more money or time into this refrigerator.
Any thoughts on what I might try?
