COMPONENT ACCESS AND REMOVAL
This section explains how to adjust, access and remove components in a Microwave Drawer Oven. An attempt has
been made to arrange these procedures in such a way as to simulate which components would need to be removed
first in order to gain access to other components. When following a component removal procedure, it may be neces-
sary to reference another component removal procedures listed earlier in this section.
NOTE: Before continuing, please take note of the WARNINGS and CAUTION below.
HIGH VOLTAGE: MICROWAVE OVENS CONTAIN CIRCUITRY CAPABLE OF PRODUCING VERY HIGH VOLT-
AGE AND CURRENT. CONTACT WITH THE FOLLOWING COMPONENTS MAY RESULT IN SERIOUS PER-
SONAL INJURY OR DEATH:
• TRANSFORMER
• CAPACITOR
• RECTIFIER
• MAGNETRON
• HIGH VOLTAGE HARNESS
• BEFORE SERVICING MICROWAVE OVEN, THE CAPACITOR MUST BE DISCHARGED BY SHORTING THE
CONNECTING LEAD OF THE RECTIFIER AGAINST THE CHASSIS WITH AN INSULATED SCREWDRIVER.
FAILURE TO FOLLOW THIS STEP COULD RESULT IN SERIOUS PERSONAL INJURY OR DEATH.
• TO AVOID ELECTRIC SHOCK, POWER TO UNIT MUST BE DISCONNECTED WHENEVER ACCESSING
AND/OR REMOVING COMPONENTS POWERED BY ELECTRICITY OR COMPONENTS NEAR OTHER
ELECTRICAL COMPONENTS.
• BEFORE WIRING:
1. DISCONNECT POWER SUPPLY CORD, OPEN DRAWER, WAIT 60 SECONDS, THEN DISCHARGE THE
HIGH VOLTAGE CAPACITOR.
2. DON’T LET THE WIRE LEADS TOUCH TO THE FOLLOWING PARTS:
• HIGH VOLTAGE PARTS: MAGNETRON, HIGH VOLTAGE TRANSFORMER, HIGH VOLTAGE CAPACI-
TOR AND HIGH VOLTAGE RECTIFIER ASSEMBLY.
• HOT PARTS: OVEN LAMP, MAGNETRON, HIGH VOLTAGE TRANSFORMER AND OVEN CAVITY.
• TO AVOID EXPOSURE TO MICROWAVES, NEVER OPERATE OR ALLOW DRAWER MICROWAVE TO BE
OPERATED WITH THE DRAWER OPEN. DO NOT OPERATE THE OVEN IF ANY OF THE FOLLOWING CON-
DITIONS EXIST:
1. DRAWER DOES NOT CLOSE FIRMLY.
2. DRAWER LATCH HOOK IS DAMAGED.
3. DRAWER GASKET OR SEAL IS DAMAGED
4. DRAWER IS BENT OR WARPED.
5. THERE ARE DEFECTIVE PARTS IN THE DRAWER INTERLOCK SYSTEM.
6. THERE ARE DEFECTIVE PARTS IN THE MICROWAVE GENERATING AND TRANSMISSION ASSEMBLY.
7. THERE IS VISIBLE DAMAGE TO THE OVEN.
• AFTER PERFORMING ANY REPAIR TO DOOR, DRAWER LATCH MECHANISM, OR DRAWER CLOSING
FACE, YOU MUST TEST INTEGRITY OF THE DRAWER SEAL WITH A MICROWAVE LEAK DETECTOR TO
VERIFY THERE ARE NO MICROWAVE LEAKS. (SEE PROCEDURES ON PAGE 4-3)
• IF NECESSARY TO REMOVE MICROWAVE OVEN FROM ITS INSTALLATION, REMEMBER THAT THE UNIT IS
HEAVY AND COULD TIP AND/OR FALL, RESULTING IN SERIOUS INJURY.
Be careful when handling sheet metal parts - Edges may be sharp.
NOTE: When all service work is completed and the oven is fully assembled, the microwave power output
should be checked and a microwave leakage test should be preformed and drawer interlock operation
checked.
