1 Panasonic Canada Inc Ambler Drive Mississauga ON L4W 2T3 Technical Bulletin Product: Code: Microwave Oven E01 Models: NNS413 NNS463 NNS513 NNS523 NNS533 NNS563 NNS573 Model Year: 2003 NNS753 NNS763 NNS953 NNS963 NNT583 NNT793 NNT993 Number: Date: TB June 30, Introduction: In continous improvement of our customer service, the component level repair program will assist the servicentre in reducing the repair turn around time at a lower service cost. Effective July 2004, the component level repair will be applied for A606Y5X00AP inverter module 2. Service Parts: A606Y5X00AP repair components are available in National Parts. 3. Technical support: Technical seminar was conducted in August Technical guide and service assistance will be provided by Consumer Products Service. Contact Thanh Pham, tpham@ca.panasonic.com Schematic diagram and parts list and Service Hint are attached. WARNING! 1. Unplug the oven when removing the outer cabinet. 2. Never touch the inverter PCB with the oven plugged in the AC outlet. 3. Do not touch the heat sink due to high voltage and high temperature. 4. Discharge high voltage by using the insulated lead jumper to short across high voltage diode D701 Anode and D702 Cathode 5. Before testing, install the inverter module completely into the oven, and make sure to have proper grounding by screwing the grounding plate onto the bottom base. 6. Do not adjust VR701.

3 Service Hint 1. Test procedure: It s recommended to use an AC line input current Ampere meter and 1 litre of water load for testing Program DPC: press CLOCK, TIMER, START, POWER pad. Unplug HV lead wire connector CN703 from inverter Program oven for 1 minute and press START After approximately 23 seconds, oven displays H98 and stops Confirm the input current is 0.8A to 1.7A during 23 seconds operation Press RESET pad Unplug CN701 Program oven for 1 minute and press START After approximately 3 seconds, oven displays H97 and stops Confirm the input current is 0.4A to 0.8A during 3 seconds operation If the above test is satisfied, the Inverter can be determined OK 2. A6065X00AP Check point: Components test: (4) DB701 (3) Q701 (1) R721, R716 R718 (2) D701, D702 (4) (3) Modification: Replace both R716 (82 K, 1/8W) and R721 (82 K, 1/8W) with one resistor part number HVL1/21653F (164 Ohm, 1/2W) as shown below to prevent a future failure. R716 Insert 164 K, 1/2W resistor From the foil side and secure it to the PCB with a silicone R721 Published by Consumer Products Service TB doc Page 3
