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 source and source Open Circuit
Between load and source Short Circuit
Between load and source Short Circuit
If incorrect readings are obtained, replace the noise lter.
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.
