What's really going on? If nothing is operating, you probably have a breaker, fuse or other power source problem. When troubleshooting electrical cooking equipment, the very first thing to do is stand back and observe the big picture. Using a liquid-filled bulb and capillary, the thermostat senses temperature inside the oven and cycles the heating system on and off to maintain oven temperature within a certain range. In an oven, the temperature is controlled by a thermostat. In fixed-temperature switch controls, heat levels are varied by applying different voltages (110V or 220V) to different coils of different resistances, as shown in figure 4-C. These are usually push-button or rotary switches with fixed settings such as warm, low, medium and high. There are also fixed-temperature switches that vary the voltage going to the heating elements to maintain fixed, pre-set temperatures. Then the bimetal cools (along with the elements) until the contacts close again. The bimetal heats (along with the element) until the contacts open. When the heating element is on, the heater inside the switch is on. (see figure 4-C) A cam attached to the control knob changes spring tension on the bimetal, which changes the amount of heat needed to open the switch. This switch has its own little heater inside, which heats a bimetal switch. When: Saturday, August 5 AM Eastern Time.Ĭlick here to go to the forum topic with the registration link.

Who: This workshop is only available to tech members at Appliantology. Look for the 'Follow' button either at the top of the topic on desktop or below the topic on mobile. If you have a PDF that isn't already in the File library here at Appliantology, send it to us by attaching it to the contact form.Īlso, follow this Calendar Event so you'll get notified of new posts here. If you have a specific appliance problem you'd like us to talk about, post it here! We need a problem statement and a PDF of the tech sheet or schematic so we can all see it on screen share. Think of it like office hours with your teachers. We're happy to walk through any concepts you're having trouble with. This workshop is also a great time for any students at Master Samurai Tech to bring any and all questions about the coursework. Webcams and microphones are open and live!

All Appliantology tech members are invited to join in this workshop on all things Appliantological: bidness, customers, tools, troubleshooting, flavorite brewski, whatever.
