This oven displays CLEAN FILTER at user defined intervals. When the message displays Amana recommends cleaning the air filter thoroughly. Cleaning the air filter will not shut off the message.

The message will stop displaying automatically after 24 hours. Depending on microwave use and environmental conditions, the filter may need to be cleaned more frequently. Once the frequency is determined, set the option for the appropriate time frame.

Oven Wall Clearances

A—For North American (UL/CSA) models, allow at least

2” (5.1 cm) of clearance around top of oven. For

International (50 Hz) models, allow at least 12” (30 cm) of clearance around top of oven. Proper air flow around oven cools electrical components. With restricted air flow, oven may not operate properly and life of electrical parts is reduced.

B—Allow at least 2” (5.1 cm) between air discharge on back of oven and back wall.

C—Allow at least 2” (5.1 cm) of clearance around sides of oven.

The switching operation of this microwave oven can cause voltage fluctuations on the supply line. The operation of this oven under unfavorable voltage supply conditions can have adverse effects. This device is intended for the connection to a power supply system with a maximum permissible system impedance Zmax of 0.2 Ohms at the interface point of the user’s supply. The user has to ensure that this device is connected only to a power supply system which fulfills the requirement above. If necessary, the user can ask the public power supply company for the system impedance at the interface point.

Adjusting Interlocks

The interlock monitor, primary, and secondary switches act as a final safety switch, protecting the operator from microwave energy. After adjusting the interlock switch assembly, verify wires are correctly connected.

For door fit and switch operation, switch bracket is adjustable.

1. Disconnect power to oven and remove outer case, (see "Outer Case" procedure).

2. Loosen switch bracket mounting screws.

3. Close oven door, move switch bracket toward rear of oven until door gap is less than 1 /

Troubleshooting Procedures

When you get a complaint from customers, evaluate the complaint carefully. If the following symptoms apply, instruct the customer in the proper use of the microwave oven. This can eliminate an unnecessary service call.

• Verify proper earthing before checking for trouble.

• Be careful of the high voltage circuit.

• Discharge the high voltage capacitor.

• When checking the continuity of the switches or the high voltage transformer, disconnect one lead wire from these parts and then check continuity with the AC plug removed. To do otherwise may result in a false reading or damage to your meter.

•

Do not touch any part of the circuit on the controller, since static electric discharge may damage the control panel. Always touch yourself to earth while working on this panel to discharge any static charge built up in your body.

Microwave oven does not work. • Inserting multiple plugs into

Output power is too low.

Sparks occur.

Uneven cooking. one outlet and using them at the same time (blown fuse or breaker).

• Microwave oven plug is not inserted tightly.

• Low AC input voltage.

• Food temperature is too low.

• Using metallic ware and allowing it to touch the oven wall.

• Ceramic ware trimmed in gold or silver is used.

Inconsistent food thickness, inconsistent fat or moisture distribution within the food products.

• Avoid using other electrical appliances when you use the microwave oven.

• Insert microwave oven plug securely.

• Use the microwave oven at adequate line voltage.

• This may not be a defect. It is possible that the food should be cooked for a longer time period.

• Do not use metallic ware for cooking.

• Do not use any type of cookware with metallic trimming.

• Use plastic wrap or lid.

• Stir once or twice while cooking soup, cocoa, milk, etc.

Testing Procedures

All Amana and Menumaster microwave oven power outputs are rated using the IEC705 standards. Using the

IEC705 test method requires precision measurements and equipment that is not practical to be performed in the field. Using the test shown below will indicate if the oven performance is satisfactory.

Test equipment required:

• 1000 ml test container and thermometer (Amana power test kit R0157397 Fahrenheit / Menumaster power test kit M95D5 Celsius).

• Digital watch / watch with a second hand for use on ovens with electromechanical timers.

Important Notes:

• Low line voltage will cause low temperature rise / power output.

• Ovens must be on a dedicated circuit, properly grounded, and polarized. Other equipment on the same circuit may cause a low temperature rise / power output.

• This test and results are not a true IEC705 test procedure and are only intended to provide servicers with an easy means of determining if the microwave oven cooking output is correct.

Procedure

1. Fill the test container to the 1000 ml line with cool tap water.

NOTE: Water temperature should be approximately 60 °F / 16°C

2. Using the thermometer, stir water for five to ten seconds; measure, and record the temperature (T1).

3. Place test container of water in the center of oven cavity and close door.

4. Heat the water for a 33-second full power cycle.

NOTE: Use a digital watch or a watch with a second hand for ovens with electromechanical timers.

5. At end of the cycle, remove test container. Using the thermometer, stir water for five to ten seconds and record temperature (T2).

6. Subtract the starting water temperature (T1), from the ending water temperature (T2) to obtain the temperature rise ( ∆T).

7. If the temperature rise ( ∆T) meets or exceeds the minimum, the test is complete. If the temperature rise (∆T) fails to meet the minimum temperature rise, test the line voltage to verify it is correct. Then repeat steps 1 - 6 making sure to change the water. If the temperature rise (

∆T) fails to meet the minimum temperature rise again the oven will require service.
