In this guide, I will discuss the dryer motor with the following electrical properties for the heating element: 240V, and 25 Amps for terminals 1, and 2. Keep in mind that the lower the resistance, the easier it is for current to flow through the circuit! 2 popular types are brass sleeve bearings and steel ball bearings. I have tried it all myself, and consider myself competent. Zero the multimeter tool by moving two probes together.

Hunker may earn compensation through affiliate links in this story. The difficult part of this task is gaining access to the switch. If the meter readout indicates "0" resistance, the capacitor is shorted out and needs to be replaced. How to Test a Dryer Timer Motor. Functioning as the heart of every dryer, the timer is nothing more than just sets of cam-operated switches. What is the first thing to do when using the ohmmeter? For information on how to check the fan and the bell housing, read on! 5. Now grab the multi-tester and set it to read ohms.

Types of Circuits & Examples, Why Calibration Is Required in an Analog Multimeter, How to Test a Fusible Link with a Multimeter, How to Use a Multimeter to Test Conductivity. If you see an error, try reloading the page. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. If the capacitor is good, the readout will read a very high or infinite resistance. I would love to hear your views and please share this guide if you find it useful. Check the terminals and connectors for possible corrosion. Try to locate a schematic for your dryer. The first step in using an ohmmeter is setting it up. Take a close look at the timer motor control. Also, check if your blower or any other device connected to the dryer motor is working well. No matter what your electric motor is powering, there are easy ways to test it, both with a multimeter and visually. To test a refrigerator's temperature control, for example, pull the temperature control knob away from the refrigerator's wall and touch each alligator clip to one of the temperature control's two terminals. This image is not<\/b> licensed under the Creative Commons license applied to text content and some other images posted to the wikiHow website. Terminal 6 is wired to the red or black wire that is then connected to terminal five, the white wire goes to terminal 5, and the green wire goes to the ground. Darkened paint in the middle of the motor (indicating excessive heat), Evidence of dirt and other foreign matter having been pulled into the motor windings through openings in the housing. While most of today's dryers also feature auto shutoffs when the chamber air hits a certain temperature, they still require the use of a timer motor to operate. In general to rewire a dryer motor to another device follow these steps: The system comprises the start and the main winding and operates at a 115V alternating current. You can normally access it by detaching the dryers back panel. Create any custom mask you can imagine for just $9.99! To begin, you need to log into or create an account with PartSelect. Simply snap a photo, and we'll take care of the rest. "Excellent coverage. In order to check with an ohm meter, remove the two large wires on motor switch and make them electrically safe. Examples are: Testing a fuse, breaker, switch, filaments etc. It is typically the dial with the largest set of options like "optimum dry" or numerical time indicators. Drip-proof motors can be installed in damp or wet locations, so long as they are installed in such a way that water (and other liquids) can not enter due to gravity and must not be subjected to a stream of water (or other liquids) directed at or in it. Remember that open contacts should read O.L., and closed contacts must read 0. If you can not determine by wiring picture what they are, check across the two terminals with the largest wires on them. To see why your electric motor isnt working, read on. Any fluctuation in the digital readout may point to a defect. Touch one of the meter's test probes to the C terminal on the door switch and the other test probe to the N.O. terminal on the door switch. A reading of 0.L (infinity), or a reading higher than 120 ohms indicates that the element is defective or dirty. Should you need to upload, just click the "Import your copy of this document" link in the form. In any other position, the contacts on the time motor should be open. While the probes are still touching the switch's terminals, press in on and hold the switch. It works by using 2 probes to send a current through the circuit and measuring how much resistance, in ohms, that current encounters. This is a step by step troubleshooting guide for dryer motors.A few signs that your dryer motor is about to quit is when the dryer will not start back up right after completing a load of laundry. We use cookies to make wikiHow great. A dryer's timer motor keeps tabs on how long the drying cycles will run when you use your dryer. Touch each of the meter's probes to one terminal each.

With a multimeter, measure the resistance between motor frame (body) and earth. Next, manually rotate the shaft of the motor. It is not very often that the timer motor goes bad on a dryer, but knowing how to test it will definitely help rule it out as the source of your dryer's malfunction. Next, insert the plug into a wall outlet and turn the power on to verify if the motor is working. Place the meters probes on opposite ends of the conductor and look to see if the correct resistance reading shows up on the meters screen. For information on how to check the fan and the bell housing, read on! For testing larger appliances such as stoves or refrigerators, you may need to remove a panel and/or remove individual components from the appliance to test them. 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. What is an Electrical Circuit? For testing smaller appliances such as blenders and toasters, you will only need to access the electrical plug. To check an electric motor to see why it failed, look at the outside for signs of debris that has been sucked into the motor windings, as well as broken mounting holes or feet, and darkened paint that could indicate excessive heat.
