Hi Reginald,

There is a way to answer this question for all 4 loads without needing to know any resistances or, for that matter, doing any calculations.

Let’s start with this: what is the voltage drop across the Safety?

My second question is: if you do the “Zen trick” across the Ignitor and the Booster, how do you reach N?

[Susan Brown]

You got it! Good job.

[Susan Brown]

It does take a little thinking through, but sounds like you got it.

And the answer we’re looking for in 14 is, “Give information to the customer.”

Hi Anthony,

It’s in this section of the unit:

The gas valve coils can fail, but testing these isn’t always conclusive, since they can read within specifications at room temperature, but then go open under load once the dryer begins heating. If at any point during the dryer’s operation the igniter glows, but no flame is established, ***this indicates one or more failed valve coils***, and all should be replaced.

Hi – I just posted a reply in the other topic you started.

Hi Kfir,

I’m glad you are thinking through this. The overall wattage decreases because of the addition of the loose connection resistance. That is because the current changes (decreases) in the circuit due to the increased resistance (I = E/R). This brings down the wattage (P = I x E)

Does that make sense? Let me know.

[Susan Brown]

Think of it this way.

If you have a set of parallel circuits, the total current equals the sum of the current in each circuit.

Let’s say you have two circuits in parallel, and we’ll call them A and B.

If circuit A has 1 amp going through it, and circuit B has 2 amps, the total current is 3 amps.

If circuit A goes open, that 1 amp is no longer flowing through it. You will just have the 2 amps in circuit B. The total current will now be 2 amps.

Does that help?

It looks like your Alumni membership was processed this afternoon. You should have access now.

Hi Kelti,

I replied to your email yesterday about this – did you not receive it?

I don’t see that you have signed up for your free Appliantology student membership.

The “MST Student Membership Request Form” is in Unit 3 of the “Appliantology 101” course.

Hi Elisha,

Please re-read Item 4 in the “Preflight Checklist” in the first Orientation unit in the course.

You can use the PDF that a fellow student provided or purchase your own hard copy (we provide an Amazon link).

Hi Dmitry,

The Ask the Teacher Forums are for questions more specifically about the coursework – clarifications on our presentations or the quiz questions, that kind of thing.

This type of question, about an actual repair job, should be asked at Appliantology.org. If you don’t already have a membership there, you can activate your free 6-month membership (see the Orientation in your course).

Hi Bianca, and I’m glad you like the course so far!

The question is: “The ignitor stays on the entire time an oven is running.”

By “running” we mean that the heating circuit is energized. And as we say in an earlier section, “This ignitor is wired in series with the gas valve, meaning that current is flowing through both whenever the circuit is powered.”

Does that help?

Hi Roy,

Occasionally different laundry products can interact with each other to produce spots on clothing – a particular fabric softener with a particular detergent, for example. It’s not extremely common, but worth ruling out before diving into troubleshooting the washer or dryer.

[Susan Brown]

That’s correct!
