CAUTION Read the following information to avoid possible exposure to microwave radiation: The basic design of the Maytag and Amana microwave oven makes it an inherently safe device to both use and service. However, there are some precautions which should be followed when servicing the microwave oven to maintain this safety. These are as follows: 1. Always operate the unit from an adequately grounded outlet. Do not operate on a two-wire extension cord. 2. Before servicing the unit (if unit is operable), perform the microwave leakage test. 3. The oven should never be operated if the door does not fit properly against the seal, the hinges or hinge bearings are damaged or broken; the choke is damaged, (pieces missing, etc.); or any other visible damage can be noted. Check the choke area to ensure that this area is clean and free of all foreign matter. 4. If the oven operates with the door open and produces microwave energy, take the following steps. A. Tell the user not to operate the oven. B. Contact Maytag immediately. 5. Always have the oven disconnected when the outer case is removed except when making the "live" tests called for in the Service Manual. Do not reach into the equipment area while the unit is energized. Make all connections for the test and check them for tightness before plugging the cord into the outlet. 6. Always ground the capacitors on the magnetron filter box and H. V. Capacitor with an insulated-handle screwdriver before working in the high voltage area of the equipment compartment. Some types of failures will leave a charge in these capacitors and the discharge could cause a reflex action which could make you injure yourself. 4 7. In the area of the transformer, capacitor, diode, and magnetron there is HIGH VOLTAGE. When the unit is operating, keep this area clean and free of anything which could possibly cause an arc or ground, etc. 8. Do not for any reason defeat the interlock switches. There is no valid reason for this action at any time; nor will it be condoned by Maytag. 9. IMPORTANT: Before returning a microwave to a customer, check for proper switch interlock action. The primary and secondary switches MUST open when the door is actuated. The monitor switch MUST close at a 1/4 inch when the door is opened. 10.Before returning a microwave to a customer, verify the door spacing is reasonably uniform along the top, bottom, and sides, and that it measures 1/8 inch or less. 11. The microwave oven should never be operated with: • Any components removed and/or bypassed. • Any of the safety interlocks failing. • Any of the seal surfaces failing, missing, or damaged. 12.To ensure that the unit does not emit excessive microwave leakage and to meet the Department of Health Human Service guidelines, check the oven for microwave leakage using Narda Model 8100, 8200, Holaday HI1500, HI1501 or Simpson 380M leakage monitor as outlined in the instructions. The maximum leakage level allowed is 4mW/cm2. 13. If servicer encounters an emission reading over 4 mW/cm2 the servicer must cease repair and contact the Maytag Service Department immediately for further direction. Maytag will contact the proper Government Agency upon verification of the test results. 16027303 © 2006 Maytag Services Microwave Leakage Testing ! Measurement With the Outer Panel Removed W ARNING Check for radiation leakage after servicing. Should the leakage be more than 4mW/cm2 inform Maytag immediately. After repairing or replacing any radiation safety device, keep a written record for future reference, as required by D.H.H.S. and HEW regulations. This requirement must be strictly observed. In addition, the leakage reading must be recorded on the service repair ticket while in the customer’s home. Avoid contacting any high voltage components. Whenever you replace the magnetron, measure for radiation leakage before the outer panel is installed and after all necessary components are replaced or adjusted. Special care should be taken in measuring around the magnetron. Equipment Measurement With a Fully Assembled Oven • Electromagnetic radiation monitor • 600 cc glass beaker After all components including the outer panel are fully assembled, measure for radiation leakage around the door periphery, the door viewing window, the exhaust opening, and air inlet openings. Procedure For Measuring Radiation Leakage Note before measuring • Do not exceed meter full scale deflection. Leak monitor should initially be set to the highest scale. • To prevent false readings the test probe should be held by the grip portion of the handle only. • The scan speed is equal to one inch per antenna revolution or one inch per second if antenna speed is unknown. • Areas to be checked are all door seal areas and any venting parts. • Leakage with the outer panel removed...4mW/cm2 or less. • Leakage for fully assembled oven with door normally closed ...4mW/cm2 or less. • Leakage for a fully assembled oven (before the latch switch (primary) is interrupted) while pulling the door ... 4mW/cm2 or less. 1 . Pour 275 ±15 cc (9 oz ±1/2 oz) of 20 ± 5°C (68 ± 9°F) water in a beaker which is graduated to 600 cc and place the beaker in the center of oven. 2. Set the radiation monitor to 2450 MHz and use it following the manufacturer’s recommended test procedure to assure correct results. 3. While measuring the leakage, always use the two inch (5 cm) spacer supplied with the probe. 4. Press the start pad or turn on the timer and with the magnetron oscillating, measure the leakage by holding the probe perpendicular to the surface being measured. © 2006 Maytag Services Record Keeping and Notification After Measurement 1. After any adjustment or repair to a microwave oven, a leakage reading must be taken. Record this leakage reading on the repair ticket even if it is zero. 2. A copy of the repair ticket and the microwave leakage reading should be kept by the repair facility. 16027303 5 General Information This manual provides basic instructions and suggestions for handling, installing , and servicing microwave ovens.

Be sure the circuit is at least 15 or 20 A and the microwave oven is the only appliance on the circuit. It is not designed for 50 Hz or any circuit other than a 120 VAC, 60 Hz circuit. • Electrical Rating of the Oven: 120 VAC, 60 Hz. 16027303 7 General Information Electrical Requirements Grounding Instructions The oven is designed to operate on a Standard 120 VAC, 60 HZ household outlet. This appliance must be grounded. If an electrical short circuit occurs, grounding reduces the risk of electric shock by providing an escape wire for the electric current. The cord for this appliance has a grounding wire with a grounding plug. Put the plug into an outlet that is properly installed and grounded. Cleaning Before cleaning the oven, unplug the power supply cord. If impossible, open the oven door to prevent an accidental oven start. Inside of the Oven Use a damp cloth to wipe out crumbs and spillovers. It is important to keep the area between door and cavity front clean to assure a tight seal. Remove greasy spatters with a sudsy cloth, then rinse and dry. Do not use harsh detergent or abrasive cleaners. Glass Tray The glass tray can be washed by hand or in the dishwasher. ! To avoid risk of electric shock, personal injury or death, use grounding plug properly. Ask a qualified electrician if you do not understand the grounding instructions or if you wonder whether the appliance is properly grounded. Keep the electrical power cord dry and do not pinch or crush it in any way. Control Panel Wipe with a damp cloth followed immediately by a dry cloth. The Child Lock feature is also useful when cleaning the control panel. Child Lock prevents accidental programming when wiping the control panel (if so equipped). Properly Polarized and Grounded Outlet Door If steam accumulates inside or around the outside of the oven door, wipe the panel with a soft cloth. This may occur when the microwave oven is operated under high humidity conditions and in no way indicates a malfunction of the unit. Outside Oven Surface Clean with damp cloth. To prevent damage to the operating parts inside the oven, the water should not be allowed to seep into the ventilation openings. After cleaning the oven, be sure that the rotating ring and the glass tray are in the right position. Press the STOP/ CLEAR pad twice to reset any accidental key setting. 8 W ARNING Three-Pronged (Grounding) Plug For a permanently connected appliance: This appliance must be connected to a grounded, metallic, permanent wiring system, or an equipment grounding conductor should be run with the circuit conductors and connected to the equipment grounding terminal or lead on the appliance. 16027303 © 2006 Maytag Services General Information Microwave Oven Description © 2006 Maytag Services 16027303 9 Troubleshooting Procedures ! WARNING To avoid risk of electrical shock, personal injury, or death, disconnect power to microwave oven and discharge the high-voltage capacitor before servicing, unless testing requires power. ! CAUTION • • • • • Verify proper grounding before checking for trouble. Be careful of the high voltage circuit. Discharge the high voltage capacitor. When checking the continuity of the switches or of 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 printed circuit board, since static electric discharge may damage the control panel. Always touch yourself to ground while working on this panel to discharge any static charge built up in your body. Troubleshooting Table Symptom Microwave oven does not work, no display, fuse is OK.

WARNING To avoid risk of electrical shock, personal injury or death; disconnect power to microwave oven and discharge the high voltage capacitor before servicing, unless testing requires power. Power Test (Traditional Test Method) Test equipment required is Amana power test kit R0157397 (Fahrenheit), or Menumaster power test kit M95D5 (Celsius). 1. Fill the plastic container to the 1000 ml. line with cool tap water. 2. Using the thermometer; stir the water, measure, and record the water temperature. Initial water temperature should be approximately 60° F (16° C). 3. Place container on the center of the oven shelf and heat the water for 33 seconds for ovens with more than 1550 watts or 63 seconds for ovens with less than 1550 watts. NOTE: Use a watch second hand, not the oven timer. 4. Stir the water, measure and record the temperature of the water after heating time is complete. 5. Subtract the starting water temperature (Step 2), from the ending water temperature (Step 4) to obtain the temperature rise (∆T). 6. See the Traditional Power Test Temperature Chart below. NOTES: • The IEC-705 test method requires precision measurements and equipment. It is not practical to perform the IEC test in the field. To convert the traditional power test results to the approximate IEC705 rating, take the traditional power test results and add 100 watts per magnetron for the unit being tested. Example: 850 watts output using the traditional power test + 100 950 watts (1 magnetron X 100 watts) Approximate IEC-705 results • Always perform power test three times for accuracy, changing the water after each test is performed. • Variation or errors in the test procedure will cause a variance in the temperature rise. Additional power tests should be made if temperature rise appears marginal. • Low line voltage will cause lower temperature rise.

Outside ventilation requires a HOOD EXHAUST DUCT. Read the following carefully. NOTE: It is important that venting be installed using the most direct route and with as few elbows as possible. This ensures clear venting of exhaust and helps prevent blockages. Also, make sure dampers swing freely and nothing is blocking the ducts. For satisfactory air movement, the total duct length of 3¼" x 10" rectangular or 6" diameter round duct should not exceed 60 equivalent feet. Elbows, transitions, wall and roof caps, etc., present additional resistance to airflow and are equivalent to a section of straight duct which is longer than their actual physical size. When calculating the total duct length, add the equivalent lengths of all transitions and adaptors plus the length of all straight duct sections. The chart below shows you how to calculate total equivalent ductwork length using the approximate feet of equivalent length of some typical ducts. Exhaust connection: The hood exhaust has been designed to mate with a standard 3¼" x 10" rectangular duct. If a round duct is required, a rectangular-to-round transition adaptor must be used. Do not use less than a 6" diameter duct. DUCT PIECES EQUIVALENT LENGTH x NUMBER USED = Rectangular-to-Round Transition Adaptor* 5 Ft. x ( ) = Ft.
