Turn on the power unit that supplies electricity to the electric motor. Yes, then you want to check the reversing switch on the side of the housing. What should I test if my fan only works on low speed whether the switch is low or high, and the capacitor tests are fine? Make sure your hands are not touching the metal probe tips, as doing so will cause the reading to be inaccurate. Is it the fan that won't work? If you don’t get a measurement, then it means power isn’t reaching the motor, so it may not be the motor that’s faulty. A "TEFC" type motor is a "Totally Enclosed, Fan Cooled" type.

My electric chainsaw motor still runs, but sparks and heat are coming from the brushes and commutator. If you have no power at all that is the likely culprit. It reads the same or similar voltage as you noted earlier if the power source is producing electricity. The best answer I can give is to follow the instructions supplied with the motor. To create this article, 23 people, some anonymous, worked to edit and improve it over time. I would, however, proceed with the tests just to make sure that there isn’t something wrong with the fan motor because, if it is, it could make the new capacitor break down. It can sometimes be very confusing to test fan motors for people who don’t have much experience. If it has bronze sleeve bearings (rather than ball bearings) the bearings are out of oil and have seized up. If it's a 3-phase motor, you have to swap only two phases. Electrically checking a capacitor can be done with the ohm meter. Any value between and around thirty-two to forty ohms should be considered as standard value. How can I check for the cause? There are few, if any, serviceable parts in small electric motors, and generally it’s less expensive to buy a replacement rather than attempt a repair. Get out your ohmmeter, open up the fan, and check the continuity of all of the coils in the fan motor. Expect to see a very low value of resistance in ohms. Locate the two terminals and place the sensors from the end of the multimeter wires onto the two terminals as before: red on the terminal that has the red wire attached and black on the terminal that has the black wire attached. Make a note of the voltage. How To Test Ceiling Fan Wires With Multimeter masuzi September 18, 2018 Uncategorized Leave a comment 21 Views Ceiling fan testing with multimeter check for live wires in a wall fixture 3 wire ceiling fan common start run ceiling fan winding with multimeter The sensor on the end of the black wire from the meter touches the terminal that has a black wire attached. Stevens holds a General Certificate of Education from Chelmsford College of Further Education. Touch and continue touching the white – brown wire with the red multimeter probe. Note: In this test, we use one of my favorite multimeter -- Fluke 117. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/b\/b4\/Check-an-Electric-Motor-Step-1-Version-5.jpg\/v4-460px-Check-an-Electric-Motor-Step-1-Version-5.jpg","bigUrl":"\/images\/thumb\/b\/b4\/Check-an-Electric-Motor-Step-1-Version-5.jpg\/aid875714-v4-728px-Check-an-Electric-Motor-Step-1-Version-5.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"
