TROUBLESHOOTING OPERATIONAL PROBLEMS

NOTE: The fryer has two independent burner systems, whose only common components are in the control system (CONTROLLER, TEMPERATURE PROBE and HI-LIMIT THERMOSTAT). Troubleshooting efforts should isolate a problem to either: an individual burner system; or, to the control system.
