TEST PROCEDURES

PROCEDURE

LETTER

COMPONENT TEST

1. Disconnect the power supply cord, and then remove outer case.
2. Open the door and block it open.
3. Discharge high voltage capacitor.
4. Disconnect the leads to the primary of the power transformer.
5. Using an ohm-meter, check between the terminals as described in the following table:

MEASURING POINT

     INDICATION OF OHM-METER

Between N and H

              Open Circuit

Between terminal N and GRY

  Short Circuit

Between terminal H and RED

  Short Circuit

If incorrect readings are obtained, replace the noise filter.

6. Reconnect all leads removed from components during testing.
7. Re-install the outer case (cabinet).
8. Reconnect the power supply cord after the outer case is installed.
9. Run the oven and check all functions.
