Stirrer Motor, High Voltage Diode - Thermador CM301B Service Manual

Lit. No. 94-30-006B
STIRRER MOTOR
Connectors
Refer to Page 14 to access the stirrer motor. To
test the stirrer motor, perform the following
steps.
1. Turn off the electrical power to the oven.
2. Set the ohmmeter to the R x 1 scale.
3. Disconnect the stirrer motor wire going to
the terminal block.
4. Touch the test leads to the motor connec-
tors. The meter should indicate approxi-
mately 1.5 Ω.
HIGH VOLTAGE DIODE
Cathode (–)
Anode (+)
CAUTION: DISCHARGE THE HIGH VOLT-
AGE CAPACITOR BEFORE TESTING THE
DIODE. REFER TO PAGE 18 FOR THE PRO-
CEDURE.
Refer to Page 19 to access the high voltage
diode. To test the high voltage diode, perform
the following steps.
1. Turn off the electrical power to the oven.
2. Set the ohmmeter to the R x 1 scale.
3. Disconnect the wires from the diode.
IMPORTANT: Use the above photo for the
proper terminal polarity connections. Disre-
gard any other polarity markings on the diode
body.
4. Touch the negative (–) meter lead to the
cathode terminal and the positive (+) lead
to the anode terminal. The meter should
indicate continuity (current flow).
5. Switch the test leads and the meter should
indicate a very high resistance.
