TROUBLESHOOTING
IMPORTANT: 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 components 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.
