There are many standard items a CSR should collect from the customer (name, address, contact information, type of appliance, etc.), but I'd like to focus on the key features of a good service ticket that may be overlooked by some. If you make sure to follow these tips, you'll set your techs up for the easiest prediagnosis and best service calls possible.
1. Collect a valid model number
A model number is essential for a tech's prediangosis. Without it, he cannot get the correct in
We talk a lot here at Appliantology about always consulting the schematic as the first step of your troubleshooting. But how exactly do you do that?
That's where the Troubleshooting Ten Step Tango comes in! Watch the clip below where the Samurai demonstrates how to use this reliable, universally applicable troubleshooting framework to troubleshoot a real-world refrigerator scenario.

Manufacturers do sometimes help us techs out -- Samsung has been putting on training sessions pretty regularly both for their own models, and for Dacor-branded models as well (Samsung acquired Dacor a few years back, for those who don't know). While a lot of how we troubleshoot is by understanding the principles that are common to all appliances, you always need a bit of info specific to the appliance you're working on. In particular, information about the exact implementation of the technology
We had a great webinar this past Sunday all about troubleshooting a Thermador wall oven with a cooling fan that wouldn't run. Lots of vital tech know-how covered in this one, like how to structure your troubleshooting flow, identify loads and switches on schematics, and perform useful and meaningful tests that will lead you to the correct solution.
In this short excerpt from the recording of that webinar, we talk about using the schematic to identify EEPs for your testing -- no unnecessary
Special guest presenter Mark Williams will show you how easy it is to diagnose temperature problems in the newer electronically-controlled refrigerators and how to do it right the first time.
We'll show you examples from Samsung, LG, GE, Whirlpool, and Electrolux. You'll see that they all work the same way.
You'll also see how to accurately test thermistors from the computer control board and you’ll learn the difference between resistance and voltage drop when it comes to testing the
During the second half of my stay at ASTI 2020, I got the chance to get the inside scoop on Bosch dishwashers and many different kinds of Beko appliances. While the Bosch training didn't have much new to say, I got a pretty good look at the nuances of Beko products. They've got some nifty features that I haven't seen elsewhere, but there are some quirks to their design and documentation that could make for difficulties with repairs.

How do you use a schematic to analyze a circuit, and how do you then apply that knowledge to a real-world troubleshoot?
That's the question we answer in this Schematic Workshop webinar! We start off by working through the most interesting parts of this dryer circuit, and then we move on to several more schematic exercises. You can watch an excerpt of the full webinar below:

Knowing how to properly use a schematic for your troubleshooting is key to saving money and time. In this short presentation, the Samurai shows performing circuit analysis to identify the most useful, but also the most convenient tests to quickly zero in on the problem. Topics covered include:
- reading schematic diagrams
- strategic selection of your reference voltage
- doing live testing (appliance plugged in and running) vs. Ohms testing
- using a loading meter to test AC line vol
In this short, easily-digestible technical workshop, we dive into some of the wacky things that can happen when a sloppy tech miswires a dryer terminal block. In fact, this dryer looks like it shouldn't be able to run -- the neutral wire isn't even connected! And yet it does run. How, you ask? That's exactly what you'll need to watch and find out.
This and our dozens of other technical training webinar recordings are only viewable by premium tech members at Appliantology.

Long gone are the days when we techs had any excuse to be scared by names like LG or Samsung. Through information tools like Appliantology, we have access to all the technical docs we need to service these models. And anyone who has spent time examining the schematics and service manuals for Samsung appliances knows that there's nothing weird or proprietary going on here -- maybe a bit of Korenglish here and there, but how electricity works and the fundamental technology used in all appliances i
If a dryer's motor isn't running, and you hear a strange humming noise coming from the start switch, what does that mean for the switch? And if you want to test that switch, what's the best way to do that?
These are questions that we answer right here in this short excerpt from one of our many in-depth technical training webinar recordings. Give it a watch and learn the answers for yourself...

We've got quite the library of awesomely informative webinar recordings here at Appliantology -- literally days worth of it! Don't believe me? Here's a little taste.
Push to start switches are extremely common technology in dryers, but do you actually know how they work? And do you know the fatal troubleshooting error that can lead you to misdiagnose them? Watch this short excerpt to find out.

Want to really put your technical know-how to the test? Well, have we got the webinar for you!
This one covers a whole potpourri of circuit puzzles and troubleshooting scenarios, including:
Some pop quizzes about series and parallel circuits
Diodes, how they work, and the surprisingly tricky situations that can arise because of them
Loads in series, how they work, and what they look like in a real refrigerator schematic
A real world troubleshooting scenario invo
Sometimes, the schematics that manufacturers give us aren't as clear as we would like them to be. Take this refrigerator, for example:
There are a few confusing things going on with this schematic, but we'll start with the part I've circled. What is that rectangle? It's drawn with the same lines as all the wires, and we're seeing connections going directly to it. There's no label anywhere calling it out as a discreet component. Could it be that that rectangle really is a loop of wire
Say you're working on the cooktop of a Frigidaire gas range, and after chasing some wires, you find that this component is in the circuit, right after the power comes in from the outlet:
The label calls it a "signal transformer", but what is the point of this device, exactly? Well, as with most circuit mysteries, the schematic will give us some more insight...
How odd -- a transformer that, seemingly, doesn't do anything. You have 120 VAC going to the primary, and 120 VAC c
Electricity and circuits are at the core of what we do as techs. You've got to have a solid understanding of these in order to do any meaningful troubleshooting. So that's exactly what we cover in this excerpt from one of our many technical training webinar recordings. Give it a watch and build yourself a solid foundation!
This video is an excerpt from a longer Master Samurai Tech webinar and is free for anyone to watch. In the full webinar, we covered topics such as:

With the ongoing COVID-19 crisis, things are changing quickly. No matter how long or short the actual pandemic lasts, everything won't just go back to how it used to be, and if we appliance repair techs want to stay in business, we will have to adapt.
What exactly that adaptation looks like remains to be seen, but Team Samurai has been in the business long enough to have some solid ideas about it. Heavy sanitation precautions are something that is already happening and will continue to beco
Some circuits have a bit more going on than they seem at first glance, and this Whirlpool washer has one such circuit. Watch the excerpt below to learn how to unravel this tangled mess of lines and apply it to your troubleshooting.

When it comes time to perform the repair and install a new part, the last thing you want is a surprise throwing a wrench in your plans. All the unexpected twists and turns should have already been dealt with during your troubleshooting. Ideally, performing the repair itself should just mean doing as little disassembly as possible, installing the new part, and collecting your repair fee.
While there will always be unforeseen problems every now and then, there are a couple rules of thumb to a
Samsung has developed something of a reputation in the tech community, and not necessarily the most flattering one. Many consider the brand to be overly-complicated and impossible to troubleshoot, and some refuse to work on these machines at all. But is this attitude really warranted?
All appliances everywhere work on the same principles, and Samsung is no exception. The idea that Korean appliances like Samsung and LG somehow work differently is pure mythology, and this short excerpt from o
Here's a weird one for you: how does this dryer run with the neutral wire of the pigtail completely disconnected? To find out, watch this short, 7-minute excerpt from one of our many full-length technical training webinar recordings.
In this video, you'll learn the answer to questions like:
What is the difference between 3 and 4 wire dryer cords?
Why should neutral and ground be separated?
Why is the dryer able to run without neutral connected?

In this excerpt from one of the many technical training webinar recordings available to our members, we cover two tricky areas that have tripped up many a tech: deciphering an unclear schematic, and decoding a convoluted customer problem description. Both of these are essential skills for any tech, since if you mess up either of these steps, the entire rest of your troubleshooting will be thrown out of whack.
The troubleshooting framework that we're using in this video is our patented Ten-S
Merry Christmas to all the Appliantology Brethren! Here's hoping that this holiday is capping off a great year for your business, and that an even better year is just around the corner.
