Product Information Stirrer Blade Transformer High Voltage Distributes microwave energy throughout the cavity. High voltage transformer is used in this unit, which supplies high voltage A.C. for operation of the magnetron tube. Blower/Fan Assembly Circulates cooling air throughout the convection or microwave oven compartment and cavity. High Voltage Capacitor Doubles the A.C. output voltage from the high voltage transformer. Stirrer Cover Covers and protects the stirrer blade assembly.

Test Modes Microwave Power Test (TRADITIONAL TEST METHOD) Test Equipment Needed: • Amana power test kit R0157397, Fahrenheit or • Menumaster power test kit M95D5, Centigrade. 1. Place one rack in the oven using lowest rack position. 2. Fill the plastic container to the bottom of the 1000 ml. lines with cool tap water. 3. Using the thermometer; Fahrenheit or Centigrade, stir the water, measure and record the water temperature. IMPORTANT: Initial water temperature should be approximately 20°C (60°F). 4.
Test Modes Convection Temperature Test Convection Temperature Calibration NOTE: It is absolutely necessary to own and use a thermocouple type oven tester to accurately measure oven temperature. No other type of thermometer can take its place. NOTE: It is normal for the average oven temperature to vary from the oven setting by as much as 25°F (14°C). Difference will not effect cooking since recipes are written with this difference in mind.
Microwave Leakage Test ! Measurement With the Outer Case Removed WARNING ! Check for radiation leakage after servicing. Should the leakage be more than 4mW/cm2 inform Amana 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 at the customer’s location.
Display Diagnostics ! CAUTION All repairs as described in this troubleshooting section are to be performed only after the caution procedures one through eight listed below have been followed. 1. Check grounding before checking for possible causes. 2. Be careful of the high voltage circuit. 3. Discharge high voltage capacitor. 4. 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.

IMPORTANT SAFETY INSTRUCTIONS ! Recognize this symbol as a SAFETY message Recognize this symbol as a HOT SURFACE WARNING ! WARNING When using electrical oven, basic safety precautions should be followed to reduce risk of burns, electric shock, fire, or injury to persons or exposure to excessive microwave energy. 1. READ all instructions before using equipment. 2. READ AND FOLLOW the specific PRECAUTIONS TO AVOID POSSIBLE EXPOSURE TO EXCESSIVE MICROWAVE ENERGY on page 2. 3. 11.
IMPORTANT SAFETY INSTRUCTIONS ! CAUTION To avoid risk of personal injury or property damage, observe the following: 1. Briskly stir or pour liquids before heating with microwave energy to prevent spontaneous boiling or eruption. Do not overheat. If air is not mixed into a liquid, liquid can erupt in oven or after removal from oven. 2. Do not deep fat fry in oven. Fat could overheat and be hazardous to handle. 3. Do not cook or reheat eggs in shell or with an unbroken yolk using microwave energy.
Installation Unpacking Oven • • • • Inspect oven for damage such as dents in door or inside oven cavity. Report any dents or breakage to source of purchase immediately. Do not attempt to use oven if damaged. Remove all materials from oven interior. If oven has been stored in extremely cold area, wait a few hours before connecting power. ! WARNING To avoid risk of electrical shock or death, this oven must be grounded and plug must not be altered.

Convection Cooking ! CAUTION To avoid risk of burns, handle utensils, racks, and door with care. Allow oven, utensils, and racks to cool before cleaning. Oven, utensils, and racks, become hot during operation. Convection Cooking Convection cooking utilizes both a convection element and fan to evenly distribute heated air throughout the oven cavity. By circulating air, no hot or cold spots occur, creating a consistent temperature envelope around the food.
Combination Cooking (microwave and convection) ! CAUTION To avoid risk of burns, handle utensils, racks, and door with care. Allow oven, utensils, and racks to cool before cleaning. Oven, utensils, and racks, become hot during operation. To operate the oven for combination cooking, you can use preprogrammed pads or manual time entry. The following instructions are for combination cooking only. For convection only cooking, see that section. Combination Cooking With Preprogrammed Pads 1. 2. 3. 4. 5. 6.

User Maintenance Replacing Oven Light 1. 2. 3. 4. 5. 6. ! WARNING Disconnect electrical supply. Remove screw from access cover on top left wall of oven exterior. While wearing protective gloves, unscrew the light bulb counterclockwise. Replace light bulb with 230-volt (rated 250V), 40-watt appliance bulb. • Do not over tighten bulb or it may be difficult to remove later. Replace light bulb cover and access cover before use. Reconnect power supply.
Care and Cleaning Clean oven frequently to maximize oven life, performance, and efficiency. A dirty oven cooks inefficiently because moisture, spills, and grease absorb convection and microwave energy. ! WARNING To avoid electrical shock which can cause severe personal injury or death, unplug power cord or open circuit breaker to oven before cleaning oven. ! CAUTION To prevent burns, handle utensils, racks, and door with care. Allow oven, utensils, racks to cool before cleaning.
Troubleshooting ! WARNING To avoid risk of electrical shock which can cause severe personal injury or death, do not remove outer case at any time. Only authorized servicer should remove outer case. Problem Possible Cause Confirm oven is plugged into dedicated circuit. Confirm oven is on grounded circuit. (Contact electrician to confirm) Oven does not operate. Check fuse or circuit breaker. Oven operates intermittently. Check air filter and discharge areas for obstructions.
