TEST PROCEDURES

PROCEDURE

COMPONENT TEST

LETTER

 

When testing is completed,

1)Disconnect the power supply cord.

2)Open the door and block it open.

3)To discharge high voltage capacitor, wait for 60 seconds.

4)Reconnect all leads removed from components during testing.

5)Re-install the hood intake duct R.

6)Re-install the outer case (cabinet).

7)Reconnect the power supply cord after the outer case is installed.

8)Run the oven and check all functions.

MKEY UNIT TEST

1.Disconnect the power supply cord.

2.Open the door and block it open.

3.To discharge high voltage capacitor, wait for 60 seconds.

4.Remove the control panel assembly.

5.If the display fails to clear when the CLEAR-OFF pad is depressed, first verify the flat ribbon cable is making good contact, verify that the door sensing switch (stop switch) operates properly; that is the contacts are closed when the door is closed and open when the door is open. If the door sensing switch (stop switch) is good, disconnect the flat ribbon cable that connects the key unit to the control unit and make sure the door sensing switch is closed (either close the door or short the door sensing switch connecter). Use the Key unit matrix indicated on the control panel schematic and place a jumper wire between the pins that correspond to the CLEAR-OFF pad making momentary contact. If the control unit responds by clearing with a beep the key unit is faulty and must be replaced. If the control unit does not respond, it is faulty and must be replaced. If a specific pad does not respond, the above method may be used (after clearing the control unit) to determine if the control unit or key pad is at fault.

6.Reconnect all leads removed from components during testing.

7.Re-install the control panel assembly.

8.Reconnect the power supply cord.

9.Run the oven and check all functions.
