COMPONENT TESTING (Page 3)
Upper & Lower Heater Relay Test Method
1. Remove the right side access panel.
2. Measure voltage across position 1 on terminal block and neutral, position 5, on terminal block
for upper heater plate. Line voltage should be present during Pre-Heat.
3. Measure voltage across position 2 on terminal block and neutral, position 5, on terminal block
for lower heater plate. Line voltage should be present during Pre-Heat.
Interlock System Test Method
1. Remove the right side access panel.
2. Measure voltage across position 3 on terminal block and neutral, position 5, on terminal block.
Line voltage should be present at all times while press in on.
3. Place a damp towel on lower heater plate and select a menu.
4. Pull lid down to start the cook cycle. While cycle in running, measure voltage across position 4
on terminal block and neutral, position 5, on terminal block. Line voltage should be present
while the press is in operation. Once lid opens, no line voltage should be present.
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.
