Is Your Fan Not Working Due to a Faulty Capacitor?

AI Thread Summary
A malfunctioning fan may be due to a faulty capacitor, which is essential for starting single-phase induction motors. If the fan produces a humming noise but does not operate, it could indicate issues such as worn bearings or internal shorts affecting torque. Users are advised not to leave the fan running in this state to prevent overheating. Testing the fan by manually spinning the blades can help determine if the bearings are functioning properly. Ultimately, if these issues persist, replacing the fan may be necessary.

Don't leave it on and humming like that. It is stuck, and could overheat. It may be stuck because of worn out bearings, or because there are internal shorts in the windings that are reducing the overall torque, or both.

Time to replace the fan, I'm afraid.
 
could the problem be the capacitor?
single phase induction motors are not self starting, so if the capacitor is not working, the motor won't start running, am i wrong?

Interesting. Does the fan run if you start it by spinning it by hand? Do the fan blades seem to spin smoothly (no bearing problems)?
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
