FRIGIDAIRE FPMO3077TF 30-Built-in Microwave Oven

IMPORTANT INSTRUCTION

CAUTION
Disconnect from Electrical Supply Before Servicing Unit PRECAUTIONS TO BE OBSERVED BEFORE AND DURING SERVICING TO AVOID POSSIBLE XPOSURE TO EXCESSIVE MICROWAVE ENERGY

1. Do not operate or allow the oven to be operated with the door open.
2. Make the following safety checks on all ovens to be serviced before activating the Magnetron or other microwave source and make repairs as necessary
   1. Inberiock operating
   2. Proper door closing
   3. Seal and sealing surfaces (Arcing wear and other damage)
   4. Damage to or loosening of hinges and latch 5.Evidence of dropping or abuse.
3. Before turning on microwave power for any service test or inspection within the microwave-generating compartments, check the magnetron, waveguide or transmission line and cavity for proper alignment integrity and connection
4. Any defective or misadjusted components in the interlock, monitor, door seal and microwave generation, and transmission systems should be repaired. replaced, or adjusted by procedures described in this manual before the aven is released to owner.
5. A microwave leakage check to verify Compliance with the Federal Performance Standard should be performed on each oven prior to release to the owner.
6. Do not attempt to operate the oven if the door glass is broken.

OUTPUT POWER OF MAGNETRON

CAUTION

MICROWAVE RADIATION PERSONNEL SHOULD NOT ALLOW EXPOSURE TO MICROWAVE RADIATION FROM MICROWAVE GENERATORS OR OTHER PARTS CONDUCTING MICROWAVE ENERGY
The output power of the magnetron can be measured by performing a water temperature rise test Equipment needed:

1. Two 1-iter cylindrical borosilicate glass vessel (Outside diameter 190 mm)
2. One glass thermometer with mercury column.

NOTE Check line voltage under load Low voltage will lower the magnetron output Make all temperature and time tests with accurate equipment.

1. Fill the one-liter glass vessel with water.
2. Stir the water in the glass vessel with a thermometer, and record the glass vessel’s temperature (T1″, 101 ‘c).
3. Set Ater the moving oven the high water power into another operate glass for vessel, seconds place t exactly. the center of the cooking tray. (3 seconds included as a holding time of magnetron oscillation)
4. When heating is finished, stir the water again with the thermometer and measure the temperature ( T2).
5. Subtract T1 from T2. This will give you the water temperature rise. (T).
6. The output power is obtained by the following formula;
7. The normal temperature rise for this model is 9.9°C to 10.3 °c at HIGH.
   NOTE

    

   1. Variations or errors in the test procedure will cause a variance in the temperature rise. Additional power tests should be made of the temperature rise is marginal.
   2. Output power in watts is computed by multiplying the temperature rise (step 5) by a factor of 91 times the of centigrade temperature.

WARNING
Personal injury/Product Hazard

• Disconnect the power supply cord from the outlet before removing the outer cabinet from the unit.
• Discharge the high-voltage capacitor and remove the léad wires.
• The primary winding of the high-voltage transformer before conducting any of the following tests.
• Conduct all operation tests with 1 liter of water in the oven.
• Conduct a microwave energy test after performing any tests or repairs to the microwave.
• Check that all wire leads are in the correct position before operating The microwave oven.
• Grasp wire connectors when removing the wire leads from microwave parts.
• Failure to follow these instructions may result in electrical shock or other.
• Personal injury or in product damage.
