Component Removal
COMPONENT ACCESS AND REMOVAL
This section explains how to adjust, access and remove components in a Drawer Microwave 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 PERSON-
AL 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 (SEE FIG-
URE 4-1 ON PAGE 4-3).
• TO AVOID ELECTRIC SHOCK, POWER TO UNIT MUST BE DISCONNECTED WHENEVER ACCESSING
AND/OR REMOVING COMPONENTS POWERED BY ELECTRICITY OR COMPONENTS NEAR OTHER ELEC-
TRICAL 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.
• AFTER PERFORMING ANY REPAIR TO THE DOOR, DRAWER LATCH MECHANISM, OR DRAWER CLOSING
FACE, YOU MUST TEST THE INTEGRITY OF THE DRAWER SEAL WITH A MICROWAVE LEAK DETECTOR
TO VERIFY THERE ARE NO MICROWAVE LEAKS. (SEE PROCEDURES ON PAGE 4-4)
• 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 (See Following
Page).
