LG gas range oven not working

last month

LG Model LGLR5823D/00
SER# 012MMDKOT130
Hello,
I have a 5yr old LG gas oven throwing an F9 code.
My ohm reading for the ignitor was 107, (specs per LG is 45-400).
I confirmed I had 123v from the control board to the ignitor and through the ignitor to the safety valve ( 123v) but had no glow at all at ignitor.
I replaced the ignitor ( aftermarket 177 ohms), but same problem. 123v from control board, through ignitor and to safety valve. No glow at all.
I then checked amps. No amps to the ignitor, at the ignitor or to the safety valve.
Same F9 code
How can I be getting 123v through the ignitor with no amps?
(Amps were tested with two different meters. Fluke 304 clamp and Fluke T5-600)
I went ahead and have ordered an OEM ignitor ( MEE61841401) which I expect this week.
What else to check?
Thank you for any advice you may offer.

Digital voltmeter? They see phantom voltages all the time; an analog meter might show no actual voltage.

Interesting.

I will have to locate my old analog and see.

Thank you.

Do you think phantom voltage would read at the control board all the way thru to the safety valve?

Ok, used analog meter and had no voltage from control board when oven off and had 123v at control board and thru ignitor to safety valve when on on.

I installed new OEM ignitor and had the same issues;

123v from control board, thru ignitor and to safety valve. Amps = Zero.

(Ohns at safety valve 2)

I am not sure what to check next.
