Power Cord Failure.  

Take the Power Cord to a local electronics shop or Radio Shack and ask them if they would check it. The Power Cord should have 12-15 volts AC.  

If the Power Cord is not producing 12-15 volts then you will need a replacement. Please check out our on-line store or call Dedicated Customer Support.  

Trap will not start and the power cord is ok.  

Try using a different wall outlet.  

Fix the wall outlet or use another outlet.  

I had a power surge and the circuit breaker popped/blown a fuse.  

Look in your circuit breaker box to see if it was the circuit breaker that popped or to see if you have a blown fuse.  

Reset circuit breaker.
