Techs as a community have developed some bits of jargon that serve as shorthand ways of describing specific technical situations. These phrases are useful for saving ourselves time and breath, but sometimes the exact definitions get blurry. Even worse, sometimes the way that the phrase sounds gets confused for a description of the actual science/physics behind what's going on, leading to a variety of "tech myths". Let's clear up a few of these terms.

VFD (Variable Frequency Drive) systems have been around long enough now that most of us know the procedure for troubleshooting them. You have three main tests that you perform:
1. Check for the PWM (Pulse Width Modulated) signal from the main control to the inverter. This is a DC square wave data signal that alternates between 0-5 VDC. The inverter has to receive this signal from the main board in order for it to run the motor.
2. Check the 120 VAC input to the inverter board. This has

I wanted to give you all a heads up about the server migration that's currently in progress here at Appliantology. You shouldn't notice too much amiss while this is going on (besides some downtime early Saturday morning when the actual transfer takes place), but there may still be some weirdness. For example, we just noticed that some PA membership renewal notices just got sent out to a few of our users that had already renewed within the past few weeks.
Merry Christmas from Team Samurai! Here's wishing you a joyous and peaceful holiday with all of your friends and family. And after that, lots and lots of kicking appliance bootay in the new year.
Need help with your very, very last minute gift shopping? This might help you out. (Weren't appliance ads just the best back in the day?)
What do you do when a seemingly simple problem stumps you? Well, it's times like that when it's essential to have a structured troubleshooting strategy like the Samurai's Ten-Step Tango.
What is the Ten-Step Tango and how do you use it? That's exactly what we're going to teach you all about in this webinar recording, using a real-life example from here at Appliantology: an LG electric wall oven that won't heat. Strange as it may seem for such a simple problem, most techs would troubleshoot
