It is typically the dial with the largest set of options like "optimum dry" or numerical time indicators. Move the probe from the N.O. terminal to the N.C. terminal and the meter should display 0.00. An O.L. display indicates a faulty switch. Keep in mind that the lower the resistance, the easier it is for current to flow through the circuit!

It is not common for dryer timers to malfunction, and they are often misdiagnosed as having failed when they are actually fully operational. Warning: When testing an electronic circuit, be sure it is not live. Before you test the timer motor, make sure you unplug the dryer or shut off the power at the breaker panel or fuse box to prevent any electrical shock hazard. A two-terminal switch will have terminals marked C and N.O. This schematic should indicate the proper resistance reading for your specific timer motor. Whirlpool dryer motor - How to test a Whirlpool dryer motor theapplianceman 49.1K subscribers Subscribe Like Share 66K views 4 years ago Whirlpool dryer motor - How to test a Whirlpool. Locate the relay Check and clean the connectors Grab your multimeter Energize the electromagnet coil Connect a test light Test the relay's voltage Test the switch One of the various methods to test a relay is through a digital multimeter. To locate the numbers, flip your motor over and check the sides. Attach the red or black wires to their respective terminal screws. If you read 240V, Thermostats-Cycle and safety thermostats-read them with an ohm meter. We will notify you via email once verification is done. A reading of 0.L (infinity), or a reading higher than 120 ohms indicates that the element is defective or dirty. On the backside or the top of the control panel, find the screws that you will have to remove to open it up. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. Ohmmeters are typically sold along with these test leads. If you placed an order on ApplianceHelp.com the order is still valid and you can check on its status and make changes here on PartSelect.com. Connect them to separate wires on a two-terminal plug and nest the spliced terminals in a wire cap for safety. Disconnect the wires from the screws. An O.L. on the LCD indicates a defective switch.

Moreover, dryer timer assemblies are situated at the back of the control console panel. In other words, by testing a resistor while its still in a circuit board, you cant be sure that the resistance youre measuring is only coming from that particular resistor. 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). If it feels like the shaft is grinding or is hard to turn in certain spots while turning it, a bad bearing is probably the cause and the motor would need to be replaced. What could be the problem? Remove the wires from the switch. This will help to keep the finish from getting scratched. Move the switch from side to side and, with a trigger switch taped so it remains on, press on the brushes and turn the commutator by hand. If the display doesnt read 0, touch the probes against each other to 0 it out. Thank you, wikiHow.". Duston Maynes is an Automotive Repair Specialist at RepairSmith. With a multimeter, measure the resistance between motor frame (body) and earth. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. This may take a while. You can normally access it by detaching the dryers back panel. Does the timer wont advance by itself, but you see the dryers function still works when you advance it through the hand?

Test and repair a clothes dryer switch Watch on Add Tip Ask Question Comment Download Step 1: Basic Use of Tools Screwdrivers are self explanatory, but some may be unfamiliar with wiring diagrams, switch schematics, or a volt meter. His work has appeared in Family Handyman magazine, Popular Science, "Popular Mechanics," Handy and other publications. Remove the timer by detaching the remaining wires, noting how they connect, and remove the console screws to release the knob from the dryer. 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. 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. Strip about one inch of the insulation coating of the blue and the white wire with a wire stripper. "Very easy to understand and follow since I have never used a multimeter.". It works by using 2 probes to send a current through the circuit and measuring how much resistance, in ohms, that current encounters.

For information on how to check the fan and the bell housing, read on! Set the function switch on the Ohmmeter to the R X 1 scale. RULE 1: Always set an Analog meter on the Rx1 scale to test a switch or fuse. Note that the scale reads in the reverse direction of most conventional measuring scales: that is, less resistance is to the right and more resistance is to the left. This process will vary widely depending on appliance. Another source of power isn't necessary since your ohmmeter will supply all of the voltage and current for your circuit. Then its highly likely theres an issue with the timer motor. Take each probe and touch it to one wire. "The article "How to check an electrical motor" refreshed my memory enough to be able to tell the supplier. The start winding comprises thinner wires and thus experiences higher resistance. However, it could also be caused by the timer motor malfunctioning. In any other position, the contacts on the time motor should be open. Or, maybe it starts up but is underpowered or sounds like its struggling. Your motor should show little resistance (a reading of zero, or close to zero).
