TROUBLESHOOTING
IMPORTANT: YOU MUST DISCONNECT and LOCKOUT THE ELECTRIC SUPPLY and
THE GAS SUPPLY or THE STEAM SUPPLY BEFORE ANY COVERS or
GUARDS ARE REMOVED FROM THE MACHINE TO ALLOW ACCESS
FOR CLEANING, ADJUSTING, INSTALLATION, or TESTING OF ANY
EQUIPMENT per OSHA (Occupational Safety and Health Administration)
STANDARDS.
The information provided will help isolate the most probable component(s) associated with the difficulty
described. The experienced technician realizes, however, that a loose connection or broken/ shorted wire may be
at fault where electrical components are concerned ... and not necessarily the suspected component itself.
Electrical parts should always be checked for failure before being returned to the factory. The information
provided should not be misconstrued as a handbook for use by an untrained person making repairs.
IMPORTANT: When replacing blown fuses, the replacement must be of the exact rating as the fuse
being replaced.
WARNING: ALL SERVICE and TROUBLESHOOTING SHOULD BE PERFORMED BY A
QUALIFIED PROFESSIONAL or SERVICE AGENCY.
WARNING: WHILE MAKING REPAIRS, OBSERVE ALL SAFETY PRECAUTIONS
DISPLAYED ON THE DRYER or SPECIFIED IN THIS MANUAL.
