 This electric dryer has error codes that claim to be able to show whether the heater has gone open or is grounded. It turns out that the control can in fact sense this, and the way that the engineers pulled this off is both simple and tricky to wrap your head around. Watch us break it down for you...

Topics covered include:

• Voltage measurements in a control board
• How the reference affects voltage measurements in a 240 VAC circuit
• How a very high resistance load impacts a circuit
• Why a triac would be used to switch a heater

...and more!
