KFIV29PCMS03 not making ice - inlet and fascia heaters not working

I have no fault codes but my ice maker has stopped making ice. I have gone through all the diagnostics and have found no errors.
I pulled out the ice maker and found ice building up along the top of the maker as well as frost at the rear of the assembly. I found no obvious water leaks so I cleaned it up and reinstalled it. It started making ice.
I got up today expecting to find the bin close to full and was disappointed to see only a dozen or so cubes, which was empty when I started. I removed the ice maker again and found the water inlet to the water maker was frozen. I checked the heater cable atop the inlet for continuity and it checked out. I then realized, after toggling through test 19 (heater for inlet and door fascia - which is 01 on) that I have been getting frost around the fascia. That leads me to believe there is no power getting to both the water inlet heater and the door fascia heater.

What is the cause, and the remedy, for this situation?

I'm attaching your tech. data sheet below.

On your main control board volt test between P2-6 to P1-2 and see if you get 115 volts in Service Test 19.

Service Test - 19 Ice Maker Fill Tube Heater and Facia Heater Status
--->Control the Ice Maker Fill Tube Heater and Facia Heater selecting SW3 (toggle between On and Off) (01 = ON, 02 = OFF)

If not, then the main control board is the culprit:

Thanks for your reply, Jake.
If I do find voltage there what could the issue be? I know the heaters are good as I checked continuity on them.

Then you'd need to check for a broken or shorted wire to those parts.
