In this webinar, we covered a range of electric circuit topics commonly encountered in appliance repair. This excerpt focuses on alternating current basics. Other topics covered in the full webinar: - Neutral vs. Ground in AC circuits. - Deciphering some fuzzy instructions in a service bulletin for a Whirlpool inverter microwave where we had to figure out how to test the digital data input to the inverter. - From there, we talked about digital data communications in appliances using a Samsung dishwasher as an example. - We also talked about loading down in DC loads, the troubleshooting technique we would use to test for this, and why loading down is not an issue affecting AC loads. - AC loads and switches have their own special way of failing that we as techs need to be aware of: failing under load. We talked about why we don't trust ohms testing for AC loads and switches. - Finally, we talked about how a high resistance connection (less than 5 ohms!) at a thermostat in an electric dryer can cause long dry times by robbing wattage from the heating element. We used Ohm's Law to show how this happens.
