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).

HOW GAS VALVES PROVIDE INFINITE HEAT CONTROL

By controlling the amount of gas which flows to a burner, the gas valve controls the heat output. The housing is threaded on the outlet end for an orifice or hood. The grill is adjustable with the hood turned completely in toward the body, if output is correct for LP gas. As it is turned in the opposite direction, it call hi, adjusted for natural gas. The setting of such surfaces should be checked with instruments for measuring the amount of gas flow to be sure that it complies with the nameplate rating.

On the opposite end of the body, threads hold a cap to retain the spring and pull, in place. A stem on the plug extends through the cap and is provided with the surface for the knob.

The manifold is filled with gas from the supply. A bottom extension of the valve threaded into the manifold.  At the burner there’s a small surface at the opening of the zip tube. When the gas is turned on, the gas-air mixture flows into the tube toward the pilot at the opposite end. Then the tube is ignited, the flame flows back to the burner, and the burner is ignited almost instantaneously. Many newer gas ranges incorporate an electronic capacitor charge ignition. This has a small printed circuit board which spark gaps or electrodes extend to the burners. When this swift is turned to the light position, arcing occurs at file spark and flip gas jet from the burner is ignited.

When this arrangement is used, is no pilot at the burner. Some ovens use this arrangement also use a glow coil for automatic lighting, and still others use a spark pilot. The advantage of the automatic ignition system is being consumed when the appliance is not in use.  . Flame is usually the first indication of Tinting around the burner. Two thermostats may be employed on these models. One thermostat controls gas flow to the burner, increasing or decreasing the how to provide the correct heat input. The second thermostat controls system in the electric operational mode. At this time an electric heating element, rather than a gas burner, is acting as the heat source thermostat simply cycles this heater on and off as required. Check this procedure for the electric thermostat is the same as for thermo falls on electric refrigerators.

CERAMIC COOKTOPS REPAIR in Brooklyn, NY

There are two new developments in the home cooking field that we can expect to be around for a long time. The ceramic cooktop has met with great approval from housewives because of its appearance and the ease with which it can be cleaned. Elements for these units are located under the pattern for the pan, and are serviced by raising the top. Use extreme care when working around the fragile material dropped wrench or a slip of the hand can result in a chipped or cracked cooktop. Some ceramic tops use switches with sensing bulbs much like those used to control the oven. Be sure that they are repositioned exactly before securing the top in place
