Oven Door Lock Testing:
The pyrolytic self-cleaning oven uses very high heat during a special, timer-controlled 1 to 3 hour cycle, to burn off food spills and grease. During this clean cycle, the oven door is latched and locked closed until the oven cools down. If your pyrolytic self-cleaning oven does not clean itself properly, the fault could lie with the door lock or switch.
There are three basic types of self-cleaning oven door locks:
- The manual door lock is latched by hand, locking the oven door.
- The electromechanical door lock is operated either by pressing a button on the oven's control panel or by physically moving the latch. In either case, the action will activate a solenoid, which operates the latch mechanism and linkage.
- The electric door lock is activated by the user setting the cleaning controls on the control panel of the range. This activates an electric motor, which in turn activates the locking mechanism.
If there is a fault with any of these door locks, the self-cleaning operation of the oven may not operate.
- To check the function of the door latch, refer to your range's operating manual to determine the type of latch and the location of the latch's operating switch or sensor. Check that the latch is operating freely throughout its range.
- Before repairs or further testing can begin you must disconnect the electricity at the fuse panel, at the circuit breaker panel, or by pulling the plug. Make sure the power is off before proceeding. A jolt from 220 volts can be fatal, use caution!
- Set the latch to the "clean" position and test for circuit continuity at the terminals of the switch with your VOM's ohmmeter function. If there is no continuity, the switch is faulty.
REMEMBER YOU ARE WORKING WITH 220 VOLTS - USE EXTREME CAUTION!!!
