water valve - ice maker diagnostics

hi there - thanks for any advice & assistance on figuring out my used frig - kenmore 106.57282791 9/1997. i used guide @ the-appliance-c1inic dot com/modcres.html for troubleshooting. good water pressure to valve.

resistance - ohms (measured/guide standard):: TH - cycle 94/0 or infinite, VN - valve 323/300, LM - motor 233/4400-8800, LH - heater 72/72. when plugged in LN has 121V. removed valve - both water & ice measure 330 ohms.

no water thru dispenser or to ice tray. valve hum when depressing dispenser lever, no valve hum when jumping TH for cycle (the cycle did complete) or LV for valve. upon removal of valve, internal screen on water supply side is clean. maybe 1/4-1/2 cup of water out of the 2 plastic lines when disconnected. i could blow air thru both plastic lines @ the valve, so not a blockage issue.

i can get a new valve from fleabay or amazon for ~$21. i want to be sure there isnt any wiring or other problem first, of course. can i use 120v A/C to test the valve? or is there some transformer in there changing the current? the bracket is stamped 120V 60HZ 40W PART 2182105 FSP. so it looks like i can use straight 120v. i dont really care about cold water, so if i could get one of the valves to work to supply the ice maker i would be happy.

thanks again for your attention
