Component Testing Chart - KitchenAid KOST100ESS Technical Education

Component Testing Chart

This chart provides pin locations and Voltage/Resistance values for all components used in the oven. It
should be used to confirm that a component is operating properly. This chart is also available in the
Tech Sheet that is provided with every oven KitchenAid produces.
To properly check for voltage, complete the following steps:
1. Unplug oven or disconnect power.
2. Connect voltage measurement equipment to check
points.
