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!

A sense of humor is VERY important!! 😀

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?

#10 – watch the video at the end of Mod. 7, unit 2, around the 6 minute mark.

From Module 7, unit 1: “When a switch is not actuated, it is said to be in its “normal” state.”

[Susan Brown]

You just needed to end up back at the module at the end so it was a complete path.

It just has to do with how many decimal points you maintain in the calculation.

For example, 1/30 is 0.0333333…

If you round that to 0.03 and continue on with the calculation, you’ll get around 20 ohms.

If you maintain a few extra “3s” on your calculator, you’ll end up with 18.75 (ish).

Try that on your own and see if you can get the different answers.

Yes – I reset you

so looking at the hot light switches now im looking at the LF-Y if im looking at it correctly it looks like its always supplied with L2 and it gets L1 when the protector bimetal closes.

Sorry, I didn’t catch that you said “protector” bimetal in your reply above. The protector is not in the circuit for the LF hot indicator light.

but now im thinking the lights bimetal switch is the right one not the protector

yep!

I reset you

[Susan Brown]

Sounds like you’ve got it! I reset you

[Susan Brown]

Hi Rikki,

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?

[Susan Brown]

From unit 7:

The three most common electrical measurements you’ll be doing as a professional appliantologist are:

– Voltage, either DC or AC
– Resistance and its daughter test, Continuity
– AC current, which is always done with a clamp-on amp meter (or ammeter). (Note: For all practical purposes, you will not need to measure DC current in appliance repair.)

It’s just a fact – there are hardly any situations in appliance repair applications where you need to measure DC current, since we are primarily dealing with AC powered loads.
