-make sure you've turned off any levers or anything attached to it.

-if the thermal sensor is red, that means you either need to set its value up to 500 or that your reactor isn't cooling properly (put ice in it!)

-Make sure the cables leading from it are set up correctly- in particular, make sure your HV transformer is the right way around. It has one input face and five output faces.
