Else, there is a ground leakage- this is probably the reason why you get shock (if you're getting!). It's important to note that what we're looking for, on the digital multimeter reading, is a non-OL reading. If the motor itself has developed a fault, the fault may be a burnt wire or connection, a winding failure includin… If any particular phase fails the continuity test, your motor is probably burnt. If you’re testing an outlet, unscrew the faceplate and unscrew the outlet’s mounting screws. Count to three while the leads on the meter charge the capacitor.

If you want to test a blower motor capacitor of yours, make sure that you discharge it with a screwdriver before you begin the test. Always turn off, unplug, or flip the breaker on the signal that you’re testing to prevent shocks or fires. The white wire is called the run wire.

Testing the blower motor resistor with a multimeter is a simple way to determine if you need to replace the resistor. If the needle moves to a higher range, such as 10 ohms or higher, then there may be a problem with your wire, fuse, or other device. The first thing you will want to do is disconnect the power supply from the dryer. Check to see if there is an X or M in front of the ohm symbol on the reading. Amid the current public health and economic crises, when the world is shifting dramatically and we are all learning and adapting to changes in daily life, people need wikiHow more than ever.
