Power cord is not plugged in or circuitbreaker is tripped.A. Plug power cord in and verify thatcircuit breaker is not tripped.B. Controller has failed.B. If available, substitute a controllerknown to be working for thesuspect controller. If the substitutecontroller functions correctly, ordera new controller.Controller won'tactivate.C. Power supply component ortemperature control board has failed.C. If any of the components in thepower supply system (including thetransformer and temperature controlboard) fail, power will not besupplied to the controller and it willnot function.
