Troubleshooting

IMPORTANT: Refer to wiring diagram for aid in 
testing tumbler components.

To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect electric power to the tumbler before servicing.
• Close gas shut-off valve to gas tumbler before servicing.
• Close steam valve to steam tumbler before servicing.
• Never start the tumbler with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be 

reconnected to ensure that the tumbler is properly grounded.
