 When you're looking at the tech sheet and faced with a seemingly unresolvable quandary, sometimes your answers lie in the simplest place: the spec sticker of the relevant part. Part specs are a very useful and oft overlooked tool for troubleshooting that can help you puzzle out the function of a particular circuit. And in this wild and wonderful age of the Internet, you don't even need to have the part on hand to see these specs -- you can just look up a picture online!

In this workshop, we explored 3 real-world troubleshooting scenarios where having the part specs makes all the difference. Topics include:

• A BLDC evaporator fan motor in a Kitchenaid refrigerator
• Identifying PWM signal wires vs. FG wires on a BLDC motor
• Simulating a PWM signal to make a BLDC motor run
• The cooling fan in a Kitchenaid wall oven
• Locating hall sensors and understanding their function
• The icemaker auger motor of a Kitchenaid refrigerator
• High voltage DC loads and diodes
• PTCs as safety devices
