FOREWORD
This Manual has been prepared to provide Sharp Electronics Corp. Service Personnel with Operation and Service Informa-
tion for the SHARP OVER THE COUNTER MICROWAVE OVENS.
It is recommended that service personnel carefully study the entire text of this manual so that they will be qualified to render
satisfactory customer service.
Check the interlock switches and the door seal carefully. Special attention should be given to avoid electrical shock and
microwave radiation hazard.
WARNING

(A) The door is tightly closed.
(B) The door brackets and hinges are not defective.
(C) The door packing is not damaged.
(D) The door is not deformed or warped.
(E) There is not any other visible damage with the oven.
Servicing and repair work must be carried out only by trained service personnel.
DANGER
Certain initial parts are intentionally not grounded and present a risk of electrical shock only during servicing.
Service personnel - Do not contact the following parts while the appliance is energized;
HighVoltage Capacitor, PowerTransformer, Magnetron, HighVoltage Rectifier Assembly, HighVoltage Harness;
If provided, Vent Hood, Fan assembly, Cooling Fan Motor.
All the parts marked “*” on parts list are used at voltages more than 250V.
Removal of the outer wrap gives access to voltage above 250V.
All the parts marked “∆” on parts list may cause undue microwave exposure, by themselves, or when they are dam-
aged, loosened or removed.
BEFORE SERVICING
Before servicing an operative unit, perform a microwave emission check as per the Microwave Measurement
Procedure outlined in this service manual.
If microwave emissions level is in excess of the specified limit, contact SHARP ELECTRONICS
CORPORATION immediately @1-800-237-4277.
TO ACCESS INTERNET: http://www.sharpusa.com/Support.aspx
If the unit operates with the door open, service person should 1) tell the user not to operate the oven and 2)
contact SHARP ELECTRONICS CORPORATION and Food and Drug Administration's Center for Devices
and Radiological Health immediately.
Service personnel should inform SHARP ELECTRONICS CORPORATION of any certified unit found with

NOISE FILTER TEST
1. Disconnect the power supply cord, and then remove outer case.
2. Open the door and block it open.
3. Discharge high voltage capacitor.
4. Disconnect the leads to the primary of the power transformer.
5. Using an ohm-meter, check between the terminals as described in the following table:
MEASURING POINT INDICATION OF OHM-METER
Between N and H 275 - 415Ω
Between terminal N and LOAD Short Circuit
Between terminal H and LOAD Short Circuit
Fuse Short Circuit
If fuse is open, replace fuse
If incorrect readings are obtained, replace the noise filter.
6. Reconnect all leads removed from components during testing.
7. Re-install the outer case (cabinet).
8. Reconnect the power supply cord after the outer case is installed.
9. Run the oven and check all functions.
