Component Testing Chart - Electric MRC Models with AquaLift™ Technology
NOTE:
This Component Testing Chart covers different models. The range may have some or all of the components listed in the following chart.
Do not continue with the diagnosis of the appliance if a fuse is blown, a circuit breaker is tripped, or if there is less than 240+10%/-15% volt power
supply at the wall outlet.
When checking for proper voltage, complete the following steps:
1.
Unplug range or disconnect power.
2.
Connect voltage measurement equipment.
3.
Plug in range or reconnect power and confirm voltage reading.
4.
Unplug range or disconnect power after performing voltage
measurements.

Closed circuit (normal)
Open circuit if temperatures at the
back of the oven exceed 360°F (184°C)
Thermo fuse will open if it
exceeds temperature.
Measure for a closed
circuit (0 resistance).
