His work has appeared in Family Handyman magazine, Popular Science, "Popular Mechanics," Handy and other publications. TIP: If you do have a timer motor that has failed, consider replacing just the motor itself and not the entire assembly. You should receive a reading between 2000 to 30000 Ohms. By signing up you are agreeing to receive emails according to our privacy policy. Place one of the test lead probes on the "C" terminal of the door switch and the other test lead probe on the N.O. terminal. Ohmmeters are typically sold along with these test leads. Find the positive (red) and negative (black) wires. As a small thank you, wed like to offer you a $30 gift card (valid at GoNift.com). For testing smaller appliances such as blenders and toasters, you will only need to access the electrical plug. Touch one probe to the terminal where you removed the wire and the second probe to any contacts on the dryer timer. The door switch should be mounted to the back of the door frame. The outlet thermistor WE04X20685 may need to be checked as well and should measure between 78KO to 82KO at around 86F, 98KO to 102KO at . Turn off the power to the dryer. Before taking any measurements, make sure the ohmmeter works by touching the leads together. In order to check with an ohm meter, remove the two large wires on motor switch and make them electrically safe. Set your DMM to the Ohms Function and touch the probes to the terminals on the capacitor. Disconnect the wires from the screws. To see why your electric motor isnt working, read on. First, remove any wires and leads from the thermostat with a firm tug. Include your email address to get a message when this question is answered.

For a three-prong outlet, the two "hot" slots will be slanted; for a four-prong outlet the two "hot" slots will be the two outside vertical slots. To check the thermostats for continuity - - You can bypass the thermostat (just connect the 2 wires together) for testing purposes only. Then inspect each wire and look for infinite readings. A motor with high resistance will not run - or not run with speed control (as is the case when a 3-phase motor winding opens while running). You can normally access it by detaching the dryers back panel. Touch each of the meter's probes to one terminal each. Trying to use an ohmmeter on a powered circuit can cause damage to the meter, the circuit, and you. Lift the control panel and turn your setting to NORMAL DRY. If you act fast, you can fix the problem before it worsens, helping you get back to normal and increasing the systems longevity. Christina Sloane has been writing since 1992.

If the contacts are closed, the multimeters LCD will show 0.000. However, some dryers function at a 220V alternating current in the US. Immediately, the testing device should record a resistance reading from the thermistor. If its zero or reads any continuity at all, then a problem exists with either the motor or cable . "I love love love this app. By using this service, some information may be shared with YouTube. It directs electric current to the heating element and dryer motor at the right times for the cycle selected. If it is ok you should, Heat elements-Test heater element with an ohm meter. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. Thank you, wikiHow.". You should get a reading of zero. Televisions and other electronics with cathode ray tubes and microwave ovens can have capacitors charged with thousands of volts even when unplugged. A two-terminal switch will have terminals marked C and N.O. If the capacitor is good, the readout will read a very high or infinite resistance. Low, single digit resistance values are expected. Clip or touch one probe to the terminal from which you removed the wire. This image may not be used by other entities without the express written consent of wikiHow, Inc.
