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.
