I tried to fire up my Rong Fu RF45N2F tonight and failed. I did some troubleshooting and have come to the conclusion that the small transformer located inside of the control panel is defective. I have 120v on the primary side but only 4v on the secondary side. I do not know if this is correct, but I am assuming that the control circuit is either 12v or 24v. Can anybody verify this? Am I on the right track? Any other input? Thanks in advance.

Maybe it's made for 230V?

I would check the input voltage setting if it's settable. I think Blight's right.
