COMPONENT TEST PROCEDURE

NN-G61 AR

CAUTION

1.High voltage is present at the high voltage terminal of the high voltage transformer during any cook cycle.

2.It is neither necessary nor advisable to attempt measurement of the high voltage.

3.Before touching any oven components or wiring, always unplug the oven from its power source and discharge the high voltage capacitor.

•High voltage transformer

1.Remove connections from the transformer terminals and check continuity.

2.Normal (cold) resistance readings should be as follows: Secondary winding Approx. 80Ω; ~ 120Ω;

Filament winding Approx. 0Ω;

Primary winding (0v ~ 230/240V) Approx. 0Ω; ~ 3Ω;

• High voltage capacitor

2. Check continuity of capacitor with ohmmeter on highest ohm scale.

2. A normal capacitor will show continuity for a short time, and then indicate 9MΩ; once the capacitor is charged.

3. A shorted capacitor will show continuous continuity.

4. An open capacitor will show constant 9MΩ;. (Due to internal 9MΩ; resistor)

5. Resistance between each terminal and chassis should be infinite.

• Diode

1.Isolate the diode assembly from the circuit by disconnecting the leads.

2.With the ohmmeter set on the highest resistance scale, measure the resistance across the diode terminals. Reverse the meter leads and again observe the resistance reading. Meter with 6V, 9V or higher voltage batteries should be used to check the front-to-back resistance of the diode, otherwise an infinite resistance may be read in both directions. A normal diode’s resistance will be infinite in one direction and several hundred KΩ; in the order direction.

• Magnetron

Continuity checks can only indicate an open filament or a shorted magnetron. To diagnose for an open filament or shorted magnetron.

1.Isolate magnetron from the circuit by disconnecting the leads.

2.A continuity check across magnetron filament terminals should indicate one ohm or less.

3.A continuity check between each filament terminal and magnetron case should read open.

• Membrane key board (Membrane switch assembly)

Check continuity between switch terminals, by pressing an appropriate pad on the key board.

The contacts assignment of the respective pads on the key board is as shown in the schematic diagram.

• Protector diode

1.Isolate the protector diode assembly from the circuit by disconnecting its leads.

2.With the ohmmeter set on the highest resistance scale, measure the resistance across the protector diode terminals. Reverse the meter leads and again observe the resistance reading. A normal protector diode’s resistance will be infinite in both directions. It is faulty if it shows continuity in one or both directions.

NN-G61 AR specifications

The Panasonic NN-G61AR is a versatile and powerful microwave oven designed to elevate your cooking experience. With its sleek and modern design, this microwave not only enhances your kitchen aesthetic but also offers a plethora of features aimed at meeting the diverse culinary needs of today’s home cooks.

One of the standout features of the NN-G61AR is its innovative inverter technology. Unlike traditional microwaves that use a pulsing method to control cooking power, the inverter technology provides a steady stream of cooking power, ensuring even cooking and heating. This technology is particularly useful for delicate foods like fish and sauces, where precise temperature control is essential to avoid overcooking.

The NN-G61AR boasts a generous 1.2 cubic feet of interior capacity, providing ample space for various dishes. Paired with a turntable, it allows for uniform cooking by rotating food items, ensuring that every inch is heated evenly. The microwave features an intuitive control panel that simplifies operations, making it easy to navigate through different settings and functions.

Another notable characteristic is its dual cooking system, which combines microwave and grill functions. This feature allows users to not only heat and cook food but also crisp and brown it, adding a delightful texture to dishes like casseroles and baked items. With preset cooking menus and quick cooking options, preparing meals has never been easier or faster.

In terms of safety, the Panasonic NN-G61AR is equipped with a child lock feature, ensuring peace of mind for households with young children. This practical feature prevents unintended use and accidental changes to the cooking settings.

Energy efficiency is also a priority for the NN-G61AR. It operates with a power rating that reduces energy consumption without compromising performance. This makes it an environmentally friendly choice for energy-conscious consumers.

Overall, the Panasonic NN-G61AR microwave oven is a remarkable kitchen appliance that combines advanced technology with user-friendly features. Whether you are reheating leftovers, defrosting frozen items, or whipping up a quick meal, this microwave is designed to handle a variety of tasks, making it an essential addition to any modern kitchen. With its blend of functionality, efficiency, and safety, the NN-G61AR stands out as a reliable companion for your cooking adventures.
