I feel you brother. I have done everything in this post. I get almost the same resistance on all my contacts. At this point I have replaced all connectors just to rule anything out. Only time I can get an LED light on the CE wall is if I turn solenoid on gas valve to “off”, a d turn off gas supply. Then i get three blinks. I have checked for gas, which I have. Not sure where else to go. Seeing as you have replaced your valve already, not sure that will even help me. If you get a solution let me know!

Did you figure it out? Mine is doing the same thing, I can hit the gas valve with my hand when it starts buzzing and then it will usually ignite.

Welcome to TFP.

Sounds like you have a defective gas valve. You should never hit a gas valve and a gas valve that acts like that is dangerous and may not shutoff when needed.

Your gas valve should be replaced.

While hitting the main valve MAY cause it to open, when it does open in MAY NOT close. Rule #1 in any heater school has always been, "Don't hit the gas valve!" You do not want to see the results of a "runaway" pool heater. If a valve has to be hit to get it to open, a service tech is obligated to disable that heater so it won't light.
