General Information Placement of the Oven Earthing Instructions Do not install microwave next to or above source of heat, such as a deep fat fryer. This could cause the microwave to operate improperly and could shorten the life of electrical components. This appliance MUST be earthed. If an electrical short circuit occurs, earthing reduces risk of electric shock by providing an escape wire for the electric current. The cord for this appliance has an earthing wire with an earthing plug.

Display Diagnostics ! CAUTION All repairs as described in this troubleshooting guide section are to be performed only after the caution procedures one through six listed below have been followed. 1. Check earthing before checking for trouble. 2. Be careful of the high voltage circuit. 3. Discharge high voltage capacitor. 4. When checking the continuity of the switches or the high voltage transformer, disconnect one lead wire from these parts and then check continuity with the AC plug removed.
Display Diagnostics S1 Watchdog - Membrane Touch Panel CS Current Sense Watchdog circuit verifies touch panel entry. Possible Causes: 1. Shorted top touch panel. 2. Shorted side touch panel. Testing 1. Disconnect power from oven. 2. Disconnect one touch panel ribbon cable from the L.V. circuit board. 3. Plug oven in, open and close door to activate oven. 4. Wait approximately 60 seconds.
