5.25 Tracing oven door switch and door lock switch faults
(Refer to Technical Overview Section 2.31)
PROCEDURE:
Oven Door Switch
1. Push the door switch plunger in and out to ensure it is operating correctly.
2. Check to see if the door switch is faulty by holding the switch in for eight seconds. If
the oven lights switch OFF then the door switch is not faulty.
3. If the oven lights do not switch ON and OFF then check the wiring continuity between
the door lock assembly and the power module.
4. If the wiring continuity is good, replace the door lock assembly. (refer to Servicing
Instructions Section 7.23)
Door Lock Switches
ƒ Test to ensure the lock switch is switching properly.
1. Use a multimeter to check that the door lock switch readings back to the power
module are correct. When the door is not locked, Lock Switch 1 inputs should be
short circuit and Lock Switch 2 inputs should be open circuit. (The readings are vice-
versa when the door is locked.)
Figure 5.25
2. Check the continuity and insulation resistance of the lock switch wiring
ƒ Replace the door lock assembly if a wiring continuity/insulation resistance fault
cannot be repaired. (refer to Servicing Instructions Section 7.23)
ƒ If the wiring continuity and insulation resistances are good, it is likely that these
switches are not faulty. (refer to Symptom Procedure Checklist for further
component tests)
