To properly check for voltage, complete the following steps:
1. Unplug oven or disconnect power.
2. Connect voltage measurement equipment to check
points.
3. Plug in oven or reconnect power and confirm voltage
reading.
4. Unplug oven or disconnect power.
*NOTEs:
■ Disconnect the harness from the board before performing measurements.
■ See the following table for connector pin identification.

Relay Logic Chart
The chart below provides informaon about how the relays react in any cooking mode. The Legend at
the boom of the chart shows what each symbol means. During each of the convecon modes the
convecon fan and convecon element cycle on and o to maintain proper heat - no big surprise
there. The normal BAKE mode also uses the convecon fan and element to get heat build up faster in
PREHEAT and help maintain temperatures during the cycle. The convecon fan can be seen working
during the cooking mode and raises quesons by consumers. The chart conrms that the convecon
fan and element do cycle during the normal cycles too. Remember that the fan will cycle OFF
whenever the oven door is opened. This chart is available in the Tech Sheet that is provided with every
oven Kitchen Aid produces.
