R-360EG R-360ES R-360EW R- 360EZ TROUBLESHOOTING GUIDE Never touch any part in the circuit with your hand or an uninsulated tool while the power supply is connected. When troubleshooting the microwave oven, it is helpful to follow the Sequence of Operation in performing the checks. Many of the possible causes of trouble will require that a specific test be performed. These tests are given a procedure letter which will be found in the "Test Procedure "section.
CK = Check / RE = Replace Home fuse or circuit breaker blows when power cord is plugged into wall receptacle. Monitor fuse blows when power cord is plugged into wall receptacle. OFF CONDITION Any letters or indicators do not appear in display when power cord is first plugged into wall outlet. Display does not operate properly when STOP/CLEAR key is touched. (Buzzer should sound and ":" or time of day should appear in display.) Oven lamp does not light when door is opened.
R-360EG R-360ES R-360EW R- 360EZ TEST PROCEDURES PROCEDURE LETTER COMPONENT TEST 4. To test for an open filament, isolate the magnetron from the high voltage circuit. A continuity check across the magnetron filament leads should indicate less than 1 ohm. 5. To test for a shorted magnetron, connect the ohmmeter leads between the magnetron filament leads and chassis ground. This test should indicate an infinite resistance. If there is little or no resistance the magnetron is grounded and must be replaced.
