CONVECTION OVEN MOTOR AND DOOR SWITCH CHECK,
REPLACEMENT (Cont.)
5. Using a volt meter, check the voltage reading between the normally open and common contacts of the micro switch
(Fig. 50) under the following conditions:
NOTE: Volt meter reading below assumes a line voltage of 115 volts. If the unit under test is operating on a different line
voltage (i.e., 220 volts), use that value in place of 115 volts.
Condition I
With door open (door switch disengaged) and power “ON”, voltage reading should be 115 volts.
Fig. 50
Possible Problem
If 115 volts are not obtained, check for the following conditions:
A. Unit not connected to electrical supply.
B. Power switch is in the “OFF” position.
C. Bad power switch.
D. Motor or connections to motor have an open circuit.
