NOTICE

This service information is intended for use by a service technician who is familiar with proper and safe procedures to be followed
when repairing any electrical or gas appliance and who is equipped with proper tools and testing devices. Repairs covered in this
publication and made by uninformed persons can result in hazards developing due to improper assembly or adjustment. While mak-
ing such repairs, persons not having the proper background may subject themselves to the risk of injury or electrical shock which
can be serious or even fatal.
A. If the oven is operative prior to servicing, a microwave emission check should be performed prior to servicing the oven.
B. Inform the manufacturer, importer, or assembler of any certified oven unit found to have a microwave emission level in excess

of 5 mW/cm2. Repair any unit found to have excessive emission levels at no cost to the owner (see 21 CFR 1004.2) and attempt
to ascertain the cause of the excessive leakage. The owner of the unit should be instructed not to use the unit until the oven
has been brought into compliance.

C. If the oven operates with the door open: 1) tell the user not to operate the oven and 2) contact the manufacturer and/or importer

and CDRH immediately.

D. Remember to connect the monitor switch after replacement and to check interlock/monitor continuity.

IMPORTANT NOTE TO THE CONSUMER

The manufacturer will not be responsible for injury or property damage arising from service performed by anyone other than author-
ized Service Centers. If you perform service on your own products, you must assume responsibility for personal injury or property
damage which may result.
