SELF-CLEANING OVENS

The thermal element of a typical bellows-type thermostat of a bulb and a metal diaphragm connected by a capillary tube is a sealed system filled with a liquid (or sometimes gaseous). The sensing bulb is located in the oven at a point determined by the manufacturer. As the bulb is heated, the liquid or gas throughout thermal element system expands, causing an increase in pressure on the diaphragm or bellows. This actuates a switch through a mechanical linkage that provides snap-action, necessary to reduce arcing of con facts. Self-cleaning gas ranges normally use the same control as the electric ranges, with electrical solenoids opening and closing gas valves. In standard gas ranges with mechanical thermostats, the movement of the diaphragm would move a valve disk towards the seat (in the closed position). It’s easy to see that the placement of the capillary has a direct effect upon oven temperature. Be sure that it is firmly in place in the clips or brackets provided. A tube touching an oven liner gives erratic readings and sluggish operation. Sharp bends in capillary tubing can prevent transmission of pressure change to the diaphragm. To calibrate the oven thermostat, follow the same general procedures that you would for a standard oven but be certain that you turn the bake calibration screw and not the clean adjusting screw. Remove the knob from the front panel and locate the calibration adjusting screw .for the bake cycle. If it’s not readily apparent, look within the center of the control shaft or look for a movable skirt on the knob itself. You’ll probably see an arrow marked increase and pointing in a clockwise or counterclockwise direction, indicating the direction you should turn to increase or decrease temperature. Proceed to adjust the temperature following the same general guidelines given for standard ovens in the preceding chapter.

Remember, that some self-cleaning oven controls have separate calibration adjustments for the clean temperature. This requires special measuring devices and techniques, and should be left to a technician. It would be a rare occasion when a simple bake temperature calibration didn’t resolve a temperature problem. These control circuitry in various selections bring manually set by the user. The wring diagram is necessary to circuits involved. It might be helpful to know [hat I’ve observed selector switch often is blamed for many ills in self-cleaning ovens, but it seldom out to be the real culprit.

OVEN TIMERS

These are basically the same as standard oven timers with addition of one or two sets of contacts. A clock mechanism mechanically  activates the switches, depending upon the setting prescribed by the user. These contacts are often exposed, making visual inspection. Again, the timer is seldom the offender. On some models it disconnects a rear surface unit during clean cycles. Self-cleaning ovens are fitted with a latching device to lock the door when temperatures rise above 600 degrees. This latch keeps the door locked until the oven has cooled down after cleaning. It’s a safety device. You should never override or disconnect it. But sometimes the latch may not close completely, and an electrical interlock prevents the range from going to clean temperatures unless the door is secured. Or worse, perhaps the door won’t unlock at all. Before you remedy the problem, you must determine if the latch is mechanical (with a lever that you move manually to lock the door) or electrical (locks automatically when switch is turned to clean position).
