      Hi Tom,

      Normally, it would mean rolling it away from the wall so you can reach the back. But, just to make sure I’m giving you the correct answer, where did you see that in the course?

        Done!

          Great! I’m glad you asked the question. Thank you!

          Do you want me to reset that quiz so you can retake it?

            Yes, P2-6 is a good test point for the L2 side of the element.

            From the component ratings on the tech sheet, we would expect around 16 ohms resistance if the element is NOT open.

              It sounds like you are trying to find two test points that are EEPs with each other, but that is not what we’re trying to do with EEPs. Each convenient testing point needs to be an EEP with one of the power supply lines to the LOI.

              The two sides of the element are not EEPs. Any two points that have a load in between them are not electrically equivalent.

              Do you remember the two criteria for EEPs?

              Two points that
              1. are in continuity with each other, and
              2. have no voltage difference between them.

              You are basically looking for a wire that connects to the load of interest, with no other loads along the way.

              You need to put your meter probes in two locations to measure the resistance. You are looking for two test points that will be electrically equivalent to either side of the element. (same thing if this happened to be a voltage measurement)

              For example, you are correct that P1-1 is a good test point. A wire connects directly from P1-1 to one side of the element. P1-1 is an EEP for the L1 side of the element.

              Now you need an EEP for the L2 side of the element.

                Hi Travis,

                You’ve already indicated in your previous answers on the quizzes that you are trying to measure resistance (ohms) of the load of interest – the upper bake element.

                Your current answer on the unit 7 quiz is to use the test points P1-1 to P1-6. Looking at the diagram on the tech sheet, does that isolate the bake element?

                  In the schematic the switch is closed so it changes the direction of the current right?

                  “Changes direction” isn’t the best way to think of it (it could get confused with the way that AC current changes directions), but you are getting at the right idea. The switch being closed creates a certain condition that affects the voltage drop of the loads.

                    It sounds like you are guessing. You’ve gone from saying none of them get current, now two of them get current. Which two do, and which two don’t, and why?

                      What makes you say they aren’t receiving current? The problem states that you have a good 120 VAC power supply.

                        Jake – did you read what I wrote above? I moved your question to its own topic. This thread is on equivalent resistance of parallel circuits.

                        Here’s the link, but you can also just find it by looking at the list of topics in the Basic Electricity Forum.

                          There are 4 loads in that diagram (igniter, booster, main, safety).

                          For each one, tell me your current understanding of how they are laid out compared to the others – series or parallel – and if they are getting current going through them.

                            Jake – I’m moving your question to a new topic, since you have tagged onto a post that’s unrelated to the question you asked.

                                Hi JP,

                                No – the optional/bonus material is not on the Final.

                                  Hi JP,

                                  Glad that was helpful! Thanks for letting us know.

                                  Flow charts are a great visual representation of the troubleshooting process. However, each flowchart has to begin with a specific problem. In this case, it was “warm refrigerator.”

                                  We created the Ten Step Tango Troubleshooting Procedure to be a more generic form of the troubleshooting process that can be applied to pretty much any situation. In other words, to help a tech develop his own mental flowchart of how to troubleshoot any issue in the most streamlined way possible.

                                  That does take some practice, and in the Oven & Range course you will follow these steps for a number of real-world scenarios.

                                  But – we’ll keep your comments in mind. It might be good to create a few more flowcharts if that would help students visualize the process.
