Is this question talking about resistance?

Yep!

Do you remember the two questions we told you to ask when you are considering the function of a component on a schematic? “Is it a _____ or a _____?”

What’s the function of a fuse?

[Susan Brown]

Yep! It’s such a cool phenomenon – electric current being able to induce a magnetic field, which can make things move!

Hi Duane,

You wrote:

Question: I am trying to relate refrigerator frost patterns to home refrigeration unit frost patterns (maybe too different to compare?).

From the rest of your question, I assume you’re trying to relate refrigerator frost patterns to those on A/C units?

No, alternating current is just electrons movement that changes polarity (direction) over time, rather than always going in one direction.

Here are a couple of items of note in the transformer unit:

A transformer basically is a very simple static (or stationary) electro-magnetic passive electrical device

When an electric current is passed through the primary winding, a magnetic field is developed which induces a voltage into the secondary winding

[Susan Brown]

It’s first described in the Transformers unit (Module 4)

There’s one word that can be used for the answer.

Let me know if you figure it out!

Good question!
The Midterm exam, as you experienced, is pretty challenging. It requires really stepping up your game after just taking the multiple choice quizzes. That’s why we created that study sheet.

The Final exam is not quite as challenging in that way. It is largely based on the quiz questions that you encountered through the course. The biggest difference is when you get to the Open Answer exam and have to write definitions and do a few calculations on your own. The final exam has a higher first-attempt passing rate than the Midterm, if that helps you feel better! But you still do have two attempts.

So the best way to study is to review each unit and quiz, to refresh your memory. If you’ve been keeping a notebook, that will help as well.

Those are correct – good job! (Note – I’m going to hide the answers so we don’t give them away)

The water level info is still transmitted to the main PCB (you can see that clearly when you look at the photo of the board), but because it first goes through the sub PCB, it is a little ambiguous as to what constitutes “direct input”. So we’ve decided to remove that as an answer choice to avoid confusion.

I understand which ever side you get zero is where your problem is

Yep! 🙂

[Susan Brown]

You are all set now! I just sent you an email.

[Susan Brown]

yep!

Hi Scotty,

Electric dryers have some of the most interesting schematics, because the elements need 240vac (L1-L2), but the motor just runs off of 120vac (either L1-N, or L2-N).

Look at the motor on the dryer schematic (the bottom one – the top one is for the washer). The neutral line comes in from the top, and the hot line comes in from the left on the brown wire. Do you see that, and whether that is L1 or L2?

This is a perfect question for the Dojo at Appliantology. There have been previous conversations about home warranty companies. Search for those threads, or start your own. We do not have direct experience with home warranty companies, but a number of our members do, and apparently some are okay and others are terrible to work for.

In general, a small percentage of warranty work (either kind) can be useful in getting you experience and connected with customers who will hopefully call you for any COD work they have in the future. You just need to proceed carefully in terms of which companies you connect with, and don’t ignore building your COD customer base through other means as well.

The hardest and most valuable part of appliance repair is doing a correct diagnosis so that you know which part to replace, so that’s where we focus our teaching.

Actually replacing the part is normally straightforward, and there are instructions provided by the manufacturers and/or tons of free videos on YouTube showing the parts changing.
