GE Profile Harmony DPGT750GC0PL NO HEAT but it run

HI

i have fixed my friend dryer with a new thermostat but i can't fix my own .

well here is my question, i have spent around $170 for the parts that i am not suppose spend on , because ohmmeter wasn't working.

i not sure the coil is having problem or something other part ,please check the diagnostic i did below and give me some advice is it a safe bet to get a new gas valve with coil?

on the ohmmeter reading i got 1931 ohms ,on the service manual the reading should be 1800-1900.

is over by 31 , i don't know did that mean the coil is not function ?

below is the diagnostic i did for my own dryer.
