TOP HEATING ELEMENT TEST
M
1. Disconnect the power supply cord, and then remove outer case.
2. Open the door and block it open.
3. Discharge high voltage capacitor. (See Warnings and Instructions on page 3-1)
4. Make sure the heating element is fully cooled and test as follows;
a. Disconnect wire leads from the heating element and measure the resistance with an
ohmmeter. On the R x 1 scale, the resistance between the heating element terminals should
be approximately 32.7.
b. Disconnect wire leads from the heating element and measure the insulation resistance with
500V -100Mý insulation resistance meter. The insulation resistance between heating
element terminal and cavity should be more than 0.5M.
5. If the meter does not indicate above resistance, replace the top heating element.
6. Reconnect all leads removed from components during testing.
7. Reinstall the outer case (cabinet).
8. Reconnect the power supply cord after the outer case is installed.
9. Run the oven and check all functions.
N SIDE HEATING ELEMENT TEST
1. Disconnect power supply cord, and remove outer case.
2. Open the door and block it open.
3. Discharge high voltage capacitor. (See Warnings and Instructions on page 3-1)
4. Make sure the heating element is fully cooled and test as follows;
a. Disconnect wire leads from the heating element and measure the resistance with an ohm
meter. On the R x 1 scale, the resistance between the heating element terminals should be
approximately 46.5 .
b. Disconnect wire leads from the heating element and measure the insulation resistance with
500V - 100Mý insulation resistance meter. The insulation resistance between heating
element terminal and cavity should be more than 0.5M.
5. Reconnect all leads removed from components during testing.
6. Reinstall the outer case (cabinet).
7. Reconnect power supply cord after the outer case is installed.
8. Run oven and check all functions.
O THERMISTOR TEST
1. Disconnect power supply cord, and remove outer case.
2. Open the door and block it open.
3. Discharge high voltage capacitor. (See Warnings and Instructions on page 3-1)
4. Remove the back plate from the oven.
5. Remove the back plate from the oven, referring to "BACK PLATE REMOVAL".
6. Disconnect connector-E from the control unit. Measure the resistance of the thermistor with an
ohmmeter. Connect the ohmmeter leads to Pin No's B-5 and B-6.
7. If the meter does not indicate above resistance, replace the thermistor.
8. Reconnect all leads removed from components during testing.
9. Reinstall the outer case (cabinet).
10. Reconnect the power supply cord after the outer case is installed.
11. Run the oven and check all functions.
