Default Re: Control board not commanding FAV to open .

It is most likely you have contaminated fluid, laced with hydrocarbon. Send me the controller and FAV and I will examine it for you. We don't charge for repairs, just pay for the return shipping. Hrdrocarbon has a habit of being absorbed into the plastic and rubber parts and slowly releasing back into the system.

Before returning the parts try clean up the tank and all the wetted parts by re circulating 50/50 mix repeatedly. I doubt it is caused by the controller.

questions:
1. Where did you purchase the methanol?
2. What are those tapes around the blue harness?
3. Did the previous user have the similar problem?

PS board looks good.
