In this course you will take a look at some of the common service problems you’ll run into with an electric range. You’ll work through simulations that will guide you, step by step, and show you the proper way to diagnose various component failures including a faulty stove element, faulty broiler element, faulty stove switch, and a couple more. These appliances are relatively simple, but you need to make sure you’re following the right procedure so you make the correct repair safely, and without any callbacks. This is a great course to have under your belt so you can be better equipped for appliance repair. Let’s jump in and get started!

This is an assessment simulation, where you'll use the steps and skills you've learned and practiced on the Interplay platform to determine the fault and fix each scenario. Use the bottom tool bar to navigate around the environment, inspect components, access tools, and view diagrams. This is designed to mimic a real-world scenario, so there's no step by step guide giving you instructions for how to troubleshoot the scenario.

This course introduces you to the components, setup, and function of electric water heaters. You'll start by learning about the anatomy of these three types of water heaters and conclude with how to maintain them. The course will cover thermostats, heating elements, and the sequence of operations commonly found in electric water heaters. Detailed videos and unique illustrations make this course appropriate for beginners and experienced technicians alike.

In this course, you'll learn through a guided 3D simulation how to troubleshoot and repair various faults of an electric water heater. The three symptoms covered: no hot water, insufficient hot water, and a dripping relief valve, can be the result of several different component failures. You'll use a multimeter to test the wiring, a pressure gauge and a thermometer to diagnose the problems. After you learn the troubleshooting process, you'll then have the opportunity to test your skills!

In Electrical Commissioning, you will perform some critical final electrical checks and then get to turn your system on! You use a digital multimeter (DMM) to check for continuity and confirm the identity of the two pairs of wires coming from the array into the inverter. You also check for proper polarity and safety voltage. Finally, you finish your electrical tests using a megohmmeter to confirm that none of your array conductors have compromised insulation that could lead to a ground fault later on. Then you proceed to connect the array conductors to their terminals in the inverter dc switch, and then systematically energize the AC components, beginning with removal of the lockout device on the solar breaker and ending with turning on the inverter.

This course covers three electrical devices that are very likely to be encountered on electrical-related service calls - receptacles, circuit breakers, and light switches. You’ll learn the function and features of the electrical devices, relationships among them, how the devices respond to electrical problems, and how to address issues involving them. After completing this course, you’ll have a greater understanding of the devices that facilitate electrical flow.

In this course, you will get an introduction to electrical safety required by OSHA in regards to electrical installation. Followed by learning how to interpret the code. This course will also cover the general installation process and the theory behind building an electrical system in a wooden, steel and concrete structure.

This Electrical Panels course provides an introduction to the major components of electrical panels and provides safety information for the technician working with them. You will learn about the role of each component and how they contribute to the safety of the occupants of the building where it is installed.

This Electrical Safety course will prepare you with the essential knowledge necessary to stay safe in the electrical field. The course begins with an overview of OSHA (Occupational Safety and Health Administration), which oversees jobsite safety standards and inspections, followed by a review of dangers of electrical work and the effects those dangers have on the body. Next, you will learn about what personal protective equipment to wear while working and how it is the last line of defense against injury. Finally, electrical safety best practices will be presented. You’ll learn about safe techniques and tools that will help to eliminate potential dangers.
