how to test dryer motor with ohm meter
But what if the timer doesnt advance through the chosen cycle? 5. You should never use your ohmmeter to test any live circuits. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. Because youre measuring the resistance in the circuit and resistance doesnt change with the direction of current flow, the positive probe and the negative probe can be on either end of the circuit to get an accurate resistance reading. As an alternative, you can utilize needle nose pliers to pull slowly on the wire connector. Then the issue lies with the dryer timer or its internal control switch contacts. Also, check if your blower or any other device connected to the dryer motor is working well. Attach an alligator clip to each of the two terminals you need to test, such as electrical cord prongs or element leads. The first step in using an ohmmeter is setting it up. Once youve done that, you can use it to measure the resistance of any circuit simply by holding the probes on opposite sides of it. 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). An example of data being processed may be a unique identifier stored in a cookie. A good motor should read less than 0.5 ohms . Strip about one inch of the insulation coating of the blue and the white wire with a wire stripper.
