Correct. Yet, we are getting no heat in this dryer.
But there is another effect that we see when current goes through a load – it’s something you measure with your meter, and we had a whole unit on it…
What happens when current flows through a load?
The element is a load. If electrons are moving in this circuit (current flow), then they’ll be going through the element. What would that cause?
I’m glad I asked!
If current is flowing in L1, is it also flowing through the element and on the L2 side?
Hi Daniel,
Yes, that’s exactly it.
Let’s go even further to help you understand this scenario. Based on the information we give you, is current flowing through the circuit in Figure 1?
I’ve asked our Appliantology admin to help you out.
You could also review the unit in the Appliantology 101 course about searching for manuals, and how to request a manual if the search doesn’t turn up what you need.

The first scenario – that the freezer seems cold – is not saying that the freezer is at the proper temps. It is just stating the way the customer usually observes the failure sequence. They rarely know what the actual temperatures are. The first place they notice the failure is in the fresh food compartment, because it only takes a few degrees of warming to get into the food spoilage zone there.
Question 12, we are telling you that the freezer temperatures are normal, which would not be the case if the defrost system were failing.
Hope that helps!
Hi Robert,
I think you are talking about Unit 4 – correct?
There are two correct answers to this one.
You chose one of them correctly – Through L1 to H1 in the infinite switch
And as you said above, the other path for L1 is through the bimetal switch.
So – your explanation is correct.

My first thought is this,
A common complaint you’ll hear a lot in the field is that the freezer seems cold but the fresh food compartment is warm.
I think the word “seems” is important. Most likely, if the defrost system has failed, the freezer is starting to warm, but the customer hasn’t noticed yet.
In Question 12, we are saying that the freezer compartment temps are normal.
I’ll get others on the Team to look into this and see if there’s any further clarification that would help.
Hi Daniel,
1/30 = 0.033
1/50 = 0.020.033 + 0.02 = 0.053
1/0.053 = about 18.75
(Note – the calculator turns 1/30 into 0.0333333… Depending on how many “3’s” you keep, the final answer will vary slightly in terms of the number after the decimal point. Would be find to round it to 19 ohms.)
Hi Rodney,
Great question! That’s not a short, because you’ve got a load in the circuit.
A short is some path from Line to N that does NOT have a load in it.
When you see L1 on both sides of a load, this means that there is no voltage drop across the load. What does this tell you about current? Is it flowing through that load?
P.S. You might notice that I moved this to a new topic
Hi Ronny,
You will learn the most important things you need to know about Refrigerator Repair in our course – how they work, how to troubleshoot them, and common repairs. We introduce you to sealed system repairs. Not all techs do sealed system work, since approximately 90% of repairs on residential refrigerators do NOT involve the sealed system.
The new procedure that you mentioned is actually optional. Not all techs who work with R600 (isobutane) use the Lokring system. That topic is still in flux right now.
We wrote up a little article about all of this – check it out and let me know if you have any questions.

Sounds like a good plan!
Hi Everardo,
On our Tools list, the items are linked to Amazon.com if you want to buy them there.

Appliance repair techs don’t usually do board-level repairs such as replacing a resistor. It’s good to know what they are and how they work, since we deal with electronic boards on a regular basis. But when you’ve determined through troubleshooting that a board is malfunctioning, the vast majority of the time you will just replace the board. Repairing control boards is its own specialty, and doesn’t make sense to do in the context of in-home appliance repair.
