COMPONE NT TESTING (Page 2)
High Voltage Capacitor Test Method
1. Disconnect the sandwich press from its power source.
2. Discharge the HV capacitors.
3. Disconnect all connections from the HV capacitor.
4. Use a digital multi-meter to check the resistance and compare them to the below chart.
Between Terminals Approximately 10 MΩ and/or 1uF
Between Each Terminal and Capacitor Body Open Circuit
Magnetron Test Method
1. Disconnect the sandwich press from its power source.
2. Discharge the HV capacitors.
3. Disconnect all connections from the magnetron.
4. Use a digital multi-meter to check the resistance and compare them to the below chart.
Between Terminals Less than 1 Ω
Between Each Terminal and Magnetron Body Open Circuit
High Voltage Diode Test Method
1. Disconnect the sandwich press from its power source.
2. Discharge the HV capacitors.
3. Disconnect all connections from the HV diode.
4. Use a 500V resistance meter to check the resistance and compare them to the below chart.
Conducts only one way Pass
Open circuit both ways Fail
Short circuit both ways Fail
Conducts one way, but leaks some the other way Fail
WARNING
The microwave circuit in this appliance is extremely dangerous. DO NOT take any voltage
measurements from the magnetron, HV capacitor, HV transformer, or filament transformer while
the sandwich press is running. Doing so could result in serious injury or DEATH!
WARNING
The HV capacitors hold a high voltage charge even when the appliance is not running a menu cycle
and for a short period of time after the sandwich press is unplugged. Disconnect the oven from
incoming power before attempting any repairs.
