use an ohm meter and test to see if your inanition switch is bad. If not, then test the rest of your circuit.

 

Your comment is almost unreadable. Slow down and relax. Take your time and explain things carefully. Otherwise, nobody can help you.

 

As an absolute last resort you could get a manual and open it at "troubleshooting".
