4 things to test on a dryer

Watch on YouTube

What happens here

The video begins by instructing you to check if your dryer is receiving the correct 240V AC power. First, set your multimeter to the AC voltage mode, ensuring it's configured to read alternating current (this is often indicated by a squiggly line symbol on the dial). Carefully touch the multimeter's red and black probes to the two main power terminals (typically L1 and L2) located at the back of the dryer. A reading around 240 volts (e.g., 239V) indicates that the dryer is receiving proper power. After confirming the power supply, it is crucial to unplug the dryer from the wall outlet before proceeding with any further internal checks to ensure safety.

Goal: Confirm 240V AC power is supplied to the dryer

Is your dryer not starting? Check these four things. Let's get after it. First thing you want to do is take our multimeter, put it to volts. This squiggly line right here represents that it's AC. With our two prongs here, you're going to go ahead and you're going to touch these to here and you should get 240 volts. 240, call that 240. Go ahead and unplug your dryer. So, the next thing to check would be your thermal fuse and we can hear the beep.
