However, if your appliance is malfunctioning, then it may be a good idea to still test the timer motor in order to ascertain whether it is or isn’t the source of the problem. Step 2 Locate the timer on your dryer's control panel. … However, for some parts like a switch, fuse or electrical component, you will need to test the part using a test meter (also called a multimeter or a volt-ohm meter) in order to check it for continuity. Connect the black and red terminals with the corresponding slots. Plug the dryer in and start motor. You can use a multimeter to check the voltage and amperes your motor is using. This step will require a volt-ohm tester. If any particular phase fails the continuity test, your motor is probably burnt. This may take a while. I set my multimeter on lowest range for ohms and touched one end to neutral and the other end to the motor pin (on the control board, where the wiring harness plugs in). 6 Steps on How to Measure AC Voltage with A Multimeter With a simple multimeter, you can do a basic static test of the capacitor. There’s no need to worry which side you touch each probe to. I have tested the therm cut-off, high limit thermo, element and thermal fuse with multimeter and everything passes a continuity test except the thermistor. Steps. Check the readings on your multimeter; If your motor is good, it will have little resistance i.e.0 or close to zero. First, set your multimeter to the lowest setting, or RX1.Setting. Using a digital multimeter to check for voltage on a typical 220-240 vac dryer plug receptical. Adjust the needle to 0 if possible. You should first short the capacitor out with a screwdriver to make sure it doesn't have a charge on it that could damage your meter. A normal reading for most dryers is in the 2000 to 3000 ohms range. Digital mulimeters are easier to use than analog, and the results are more reliable. This dryer motor relay switch supplies power to the motor. Test the second set of wires: The brown wire is the start wire and the black wire is the common wire. Before you can begin to test your dryer's timer motor, you must first locate the device. The multimeter should read at or near zero. 4. Step 1 Turn off the power to the dryer. Most electronic devices work on dc voltage, ensuring conventional AC is converted. Locate the capacitor inside your appliance. A dryer’s timer motor does not go bad too often. Disconnect the motor's two wire leads from the wiring harness. The black lead goes on right, and the red lead goes on left. Now check the ground connection. If you see an error, try reloading the page. If it is, it is good. Step 5 - Check the Capacitor. Thermostats-Cycle and safety thermostats-read them with an ohm meter. Steps. All rights reserved. It should be in one of the service areas of your dryer or in the owner's manual. Place one probe on the bare metal housing of the motor. Touch each of the meter's probes to one terminal each. 1. Copyright © 1999-2020, Eldis Group Partnership. If the capacitor is good, the readout will read a very high or infinite resistance. 2. Use needle-nose pliers with an insulated handle to remove wires. Start by taking the metal ends of the multimeter leads and pressing them on top of the 2 leads positioned in the top of the heating coil. I have the Kenmore Dryer 110.62996101. You may only have to remove the screws securing the front control panel in place, or, depending on your model, your may have to remove the rear panel behind the control panel. They are labeled “+” and “-“ indicating positive and negative, respectively. 3. It should read “00” or show a very low reading if continuity is present. Use a pair of pliers to detach both wires. All we need to test a thermistor is an ohmmeter or a multimeter that contains an ohmmeter. Turn off Power. A multimeter is a versatile tool that can be used to measure electrical resistance within a circuit, just as you would use a ruler to measure distance. Set your multimeter to the R x 1 setting. Check the readings on your multimeter; If your motor … Open the cover for the lint screen on the top of the appliance. The steps include: Prior doing anything, check the rated value of the device (100Ω, 1KΩ, 10KΩ). Polarity is not an issue here. You should not receive any reading on your meter from this test. Take the other probe and touch it to the other terminal on the motor. Place the other probe on each terminal, one at a time. Remove one of the wires from the capacitor to test the resistance of the start induction run motor. By conducting a simple test with a multimeter, you can easily tell if your capacitor is still working or if it needs to be replaced. This should make the needle of the multimeter jump from zero to the right before going back to zero. Either unplug the unit from the wall outlet, remove the appropriate fuse from the fuse box, or flip the appropriate breaker in the circuit breaker panel. To determine whether a 3 phase motor is still good or has gone bad, a simple ohmmeter test across the windings of the motor will reveal its true state of health. Test your multimeter to ensure it’s working properly by touching both multimeter metal probes together (the black and the red probe). With the leads apart, you will read infinity. Disconnect the power source to your dryer before you conduct this or any other test. MultiMeter Thermocouple Test Procedure.

Try to locate a schematic for your dryer. Simply pull it out. Not all dryers have a motor relay switch. 1. Finally, reverse the leads. Check the label on the electric motor to determine the voltage and amperes it needs to operate. Capacitors are metal tubes that store an electric charge usually found near a motor in the appliance. All brand logos are trademarks of their respective owners. Touch the two leads together from the meter, and you should get a reading close to zero. The material on this site may not be reproduced, distributed, transmitted, cached or otherwise used, except with the prior written permission of WTWH Media. Using a multimeter, check the continuity of motor winding from phase to phase ( U to V, V to W , W to U ).Each phase to phase must have a continuity if winding is OK. The resistance settings are the ones measured in Ohms. Take each probe and touch it to one wire. It is normally open when the motor is idle/not running, and closes when motor runs. Sometimes a visual inspection will tell you if a part needs replacing, like a corroded bake element, or a broken dryer belt. (Check the meter's operation manual if necessary) Choose the highest scale (R X 1000 or similar) and zero the meter by touching both probes against each other.
