TROUBLESHOOTING
WARNING: YOU MUST DISCONNECT and LOCKOUT THE ELECTRIC SUPPLY and
THE GAS 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 ... not necessarily the suspect component itself. Electrical
parts should always be checked for failure before being returned to the factory.
IMPORTANT: When replacing blown fuses, the replacement must be of the exact rating as the fuse
being replaced. The information provided should not be misconstrued as a
handbook for use by an untrained person in making repairs.
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.
