Hello and welcome to JustAnswer!

There are a handful of things that could be going on. The problem may be a wiring or connection issue, a power distribution issue or a failure in the control head assuming the resistor is good.

An incandescent test light would best be used for testing a power or ground feed. Do you have power on the orange wire at the resistor connector?
