It’s the section further down the page on Circuit Protection Devices (since we are talking about things like circuit breaker panels).

Technical documentation is often tricky and/or poorly worded. That’s the value of doing these exercises to get a little used to that.

We’re here to help!

Here are the two routes for L1 to get to that light. The bimetal that is circled is just called the light’s bimetal switch. In the documentation is says this bimetal is in the element’s temperature limiter.

[Susan Brown]

Hi Joe – only two answers are correct.

Through the protector bimetal is NOT one of them. The protector bimetals are the ones labeled “protector” in a different part of the diagram.

[Susan Brown]

Good, you’re seeing the right one now.

So when the switch closes L1 goes through the light and back to L2 through the red wire?

yes

Otherwise, follow that BK (J) jumper (the line on the schematic is not continuous) up to that where it joins in near H1.

Hi Joe,

You may be looking at the wrong light. There is a single “surface indicator light” in one location on the schematic, and then there are 4 hot surface indicators lights, one for each burner. You want to find the LF light.

Let me know what you are looking at – how is it labeled?

Tip for Question 9: there are 4 correct answers

Think about the sequence of events that led to the problem – spilling stew. Did you read the explanation that showed up in the quiz results?

Since we hear a spark, we know the spark module is at least trying to do its job. Also, since flame is established, we know the spark is being delivered to the correct location on the burner head and that the burner head is delivering the fuel-air mixture to the spark location. Therefore, there’s no reason to suspect the spark module, board, or electrode. The problem must be in the return current.

I reset you.

Hi Joe,

Sometimes a little connectivity glitch can cause a problem with a quiz freezing up. As you’ve seen, it doesn’t happen often.

No worries – I reset you so you can take it again.

Hi Ronny – you found a typo! I’ve changed the “lowest” answer to now really be incorrect.

Thanks for the keen eyes and brain!

[Susan Brown]

Glad you figured it out!

Hi David,

I emailed feedback to you on the ones you missed – did you not receive that email? I sent it around 3:15 pm Eastern time.

Hotmail often puts our emails into the spam folder, so check there. Let me know!

[Susan Brown]

A sense of humor is VERY important!! 😀

[Susan Brown]

Hi David,

The question is, “Question #2 – Measuring DC current is a measurement you will probably never do as a professional appliantologist.”

Your quote above is about voltage.

Current and voltage are different properties, and therefore different measurements.

Paying attention to terminology is important for technicians!

What is the equivalent resistance of the condenser fan motor and the compressor? (Note: the compressor is off.)

First you have to find the resistance of
1. condenser fan motor
2. compressor (when it is off)

What did you find for those?
