      So it has to do with the sealed system, correct?

        Do you see where in the video he’s talking about seeing the ice ball? What type of failure is being described there?

          Just want to make sure – Did you notice the word “not” in the question?

            Hi Jim – thanks for the question! I’m going to have to consult with Mr. Samurai on this one, and he is out for the whole day. As soon as I have an answer for you I’ll get back to you.

              We talk about the ice ball about halfway through the video in that unit.

                Look at the photo in Unit 2 of several different evap frost patterns. Which one matches the description?

                    That’s a correct statement. The answer choices we give you for that question aren’t quite so detailed, but I think you’ll know which one is correct.

                      Right! So, you can only assume there will be some kind of start device, but not which type. The correct answer has to do with the type of windings that all split-phase motors will have.

                        Is the only start device a PTC type?

                          Right, which of course wouldn’t be that big of a deal with other types of appliances, but no one wants to risk their food spoiling just because of a nuisance trip.

                            We describe this in the first video during the section on PTC start device failure (starts at about 21 minutes, 25 seconds into the video)

                              You are correct! Good job!

                                Hi John!

                                Yep, this is just a matter of getting the terminology straight.

                                We should always refer to parallel circuits, plural. Each branch is a circuit with one or more loads. If loads are in parallel with each other, they are technically in different circuits, even if they are tied together at some point.

                                Does that make sense? You can tell if loads are in series or parallel with each other by doing the Zen Trick.

                                If two loads are in parallel, will the current be the same or different through them?

                                  Yep! I just wanted you to see how Ohm’s Law equations can be used to think through these things when you aren’t sure. But a fuse is basically a switch, and therefore acts like a wire (essentially no resistance, thus no voltage drop), unless of course it blows open.
