This document provides a comprehensive service manual for the Panasonic NE-1027 and NE-1037 Microwave Ovens, covering their functions, usage, and maintenance.
The NE-1027 and NE-1037 models are designed for efficient microwave cooking. The NE-1027 features a mechanical timer and power select dial, offering straightforward manual control over cooking time and power levels. Users can set the desired cooking duration and power intensity using the dedicated dials. The NE-1037, on the other hand, incorporates a digital programmer circuit with a membrane keypad and digital display window, providing more advanced and precise control. This model allows for single-stage and two-stage cooking, memory programming, and features indicators for program changes, double quantity heating, and power levels. Both models include a start button, a door safety lock system, an oven window, and an oven lamp for user convenience and safety.
For the NE-1027, manual heating involves setting the timer and power select dials. The vari-power controller in this model manages the ON-OFF time of the vari-power switch to adjust the microwave output from 100W to 1000W. A complete cycle of the vari-power controller is 26 seconds, during which the vari-power switch is turned on or off by cam rotation. The ON/OFF time ratio does not directly correspond to the percentage of microwave power, as approximately 2 seconds are required for heating the magnetron filament.
The NE-1037 offers more sophisticated usage features. Users can program single-stage or two-stage cooking sequences, storing them in memory pads for quick recall. The digital display shows the selected memory pad number, heating time, and power level. The double quantity (x2) pad allows for automatic adjustment of cooking times for larger portions. The digital programmer circuit controls the ON-OFF time of power relay B to vary the output power from low to high. A complete ON and OFF cycle of power relay B is 22 seconds. This model also includes functions to read the cycle counter, select beep tone options (ON/OFF), and lock/release the memory pad program.
Maintenance and troubleshooting are critical for ensuring the safe and efficient operation of these microwave ovens. Before any service work, it is imperative to check the earthing and discharge the high voltage capacitor, as the oven contains high-voltage, high-current components. Servicemen are advised to remove watches when working near or replacing the magnetron. If the door lock, door switch, or door seal malfunctions, the oven must not be operated until complete repairs are made to prevent hazardous microwave leakage.
Disassembly and parts replacement procedures are detailed for key components. For the magnetron, the high voltage capacitor must be discharged, and specific screws and lead wires disconnected. Proper tightening of mounting screws after magnetron replacement is crucial to prevent microwave leakage. The digital programmer circuit (D.P.C.) and membrane keyboard in the NE-1037 require careful handling due to static electricity. All connectors must be disconnected, and the escutcheon base removed to access these components. When replacing the membrane keyboard, applying hot air can aid in smoother removal, and the surface of the escutcheon base must be clean to avoid contact problems.
The low voltage transformer and power relays in the NE-1037 also have specific replacement procedures, emphasizing careful desoldering and resoldering. The fan motor and stirrer motor have straightforward removal processes involving disconnecting wires and removing screws. The door assembly requires careful removal and reassembly, with particular attention to door alignment to prevent microwave leakage. The temp sensor (thermal protector) in the NE-1037 is replaced by cutting a lead wire, removing a screw, and then soldering new wires. The floor shelf and moving antenna can be accessed through an access hole in the oven wall.
Component test procedures are provided for various parts. For the primary latch switch, door switch, and power relay B, continuity checks are performed at door opened and closed positions. The short switch and monitor are tested similarly. The high voltage transformer's primary, secondary, and filament windings are checked for normal resistance. The high voltage capacitor is tested for continuity, and a normal capacitor will show continuity for a short time before indicating high resistance. The magnetron is checked for open or shorted filaments. The variable power controller in the NE-1027 is tested for proper ON-OFF switching within its 26-second cycle. Diodes and protector diodes are checked for resistance in forward and reverse directions. The membrane keypad in the NE-1037 is tested for continuity between switch terminals when pads are tapped. The temp sensor (thermal protector) in the NE-1037 operates at 257°F (125°C) and will shut off power to the oven cavity if this temperature is exceeded.
Troubleshooting guides address common issues such as the oven not starting, fuses blowing, low microwave output, and buzzing noises. For the NE-1037, specific troubleshooting steps are outlined for issues related to the digital programmer circuit, including no display, key input not registering, and timer countdown without microwave oscillation. Adjustments for safety switches A and B, and the short switch, are also detailed to ensure proper door hook assembly and latch key movement. Microwave output measurement involves heating a liter of water for one minute and recording the temperature rise, which should be at least 8.5°C for a 1000W oven.
The manual also includes warnings about microwave radiation and high voltage, advising caution to avoid exposure and to ensure proper installation of components like the magnetron and door hinge after repair. Unauthorized copying and distribution of this manual are prohibited.
