COMPONENT TESTING (Page 1)
HV Transformer Test Method
1.
Disconnect the sandwich press from its power source.
2.
Discharge the HV capacitors.
3.
Disconnect all connections from the HV transformer.
4.
Use a digital multi-meter to check the resistance of the windings and compare them to the
below chart.
208V Winding between #1 and #2
Approximately 1 Ω
240V Winding between #1 and #3
Approximately 1 Ω
High Voltage Winding between Ground
Approximately 61 Ω
Filament Transformer Test Method
1.
Disconnect the sandwich press from its power source.
2.
Discharge the HV capacitors.
3.
Disconnect all connections from the Filament transformer.
4.
Use a digital multi-meter to check the resistance of the windings and compare them to the
below chart.
Filament Winding (check terminals on end of wires)
Less than 1 Ω
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.
