My ceiling fan does not work. I have a ceiling fan light and the fan does not turn. It just hums but the light works.  What can be the problem?

The ceiling fan/light has power. The lights work, but the fan doesn't turn even though it hums.  Why is this, and how can I fix it?

I am just starting off with hobby electronics and can't get hold of the concept of Load. Do electrical appliances also "Draw" current. An air conditioner upon start dims the light. My point is that if the voltage difference is not enough to move whatever machinery is in there then the air conditioner should stay off or not work. How come it "draws" electricity upon start?

My computer powered off the other day on its own, and now when I push the power button, nothing happens. My assumption would naturally be that the power supply is done (possibly well done) but is there any good way to test this before I buy a new one?

Is there a way to set an alarm or something for when my Ubuntu computer is about to overheat?   My computer has some temperature issues, so when it's about to overheat I'd like to turn on an external fan.

How do I ground a new overhead light fixture?  I'm replacing a 2 wire fixture with no grounding wire with a new 3 wire fixture which includes a ground wire.

I have a ceiling fan on our bedroom's vaulted ceiling. Since we don't want 7' pull-cords, the speed is stuck at full-tilt, which is no good. The fan has separate switches on the wall for lights and fan on/off, though, so I tried putting a dimmer switch on the fan. Can that do any damage to the fan's motor, or is there anything else I'm not thinking of that could be a problem? I've noticed the fan makes a little bit of a groaning noise when I have the rheostat down, but since I've never heard the fan at slow speeds, maybe that's normal.

I created an object, and I wanted it to glow. I used to just place points of light around it, and parent them to it, but using the emit option in the materials seemed so much easier.  But when I gave it an a higher emit than 0, it went only a small distance before the light stopped. I turned it up to 200, and the object was white with light, but the light didn't go any farther. Oh and I changed the color, and nothing happened.

The master bedroom and middle bedroom of my 3 bedroom mobile home is without power. None of the breakers have flipped. I even changed the breaker that controls that part of the house and my ceiling fan in my living room. Still nothing in those listed bedrooms, but the ceiling fan is working fine and I'm getting 115 VAC to the breaker. I was thinking it could be a short to one of the plugs in the middle room. It was working fine earlier in the morning. I went into the middle room to turn on an electric heater and everything went dark. I changed the plug and still nothing.  What should I do now?

My furnace pilot light keeps going out so I changed the thermocouple. Now the furnace will come on and heat up to the degree set on my thermostat, then the pilot light will go out and the furnace will not come back on.    Could the thermostat be bad and cause the pilot light to go out?

After some effort, I have determined that there is a discontinuity between the wire from the breaker (hot wire) and the receptacle (socket).  The breaker is okay because couple of other sockets in the same circuit are working.  However, several sockets downstream from this socket are not working, i.e., are dead.  The wiring in question comes from attic, through the  wall (stud) and finally to the receptacle.  Before I fix anything, how do I make sure that my diagnosis is 100% correct.  If correct, how do I fix this wire or replace the wiring without breaking the sheet rock of the bedroom wall?

I have an iPad Mini that I have had sense the fall.  This morning I woke up and it was working fine.  Now it won't turn on.  I've tried all the regular fixes and nothing is working.  Will the manufacturer warranty cover this?  Should I take it to an Apple store?

It has been some months since I've turned on my Playstation 3. Today, when I turned it on with my controllers, it didn't work. I thought "Hey, the battery surely ran out", so I tried to charge them but they don't seem to be charging at all. Could it be that they're officially weight papers by now?

To get rid of dust that had gathered near the fan, I put a vacuum cleaner to the air intake (with the computer turned off).  This removed the dust.  It also caused the fan to rotate at a fairly high speed. Quite faster than normal speed, judging from the sound.  Do I risk destroying stuff by doing this?

I can turn on my computer and sometimes it will boot up just fine. After a while of use, days or even a week, when I try to turn it on, it powers up, in that the fans spins up, the power indicator light at the front comes on (although orange, it is usually green), but it will not boot, the screen remains black and never comes on.  If I leave it for a couple days, and try it again, it comes back on, and the cycle starts over.  I have no parts for that computer that I can currently swap out to test. I have tried removing the RAM or using one stick to see if it would get any further in the process, but to no avail.  I suspect I may have a motherboard or power supply problem.  What could cause a situation like this and are there any solutions?  Edit: There is no beeping when it boots, the only thing that happens is the fans spin up and the power indicator comes on orange.

I just purchased and installed a new Panasonic FV-10NLF1 inline exhaust fan.  My house has copper wiring, but the wires on the fan appear to be aluminum (they are silver in color).  I didn't think anything was made with aluminum wire anymore.    What special considerations do I need to take when connecting the copper house wiring to the fan wires?

I live in an older house and have some outlets in our kitchen that don't make sense to me. We have one outlet that is tied to a dimmer switch on the opposite side of the room. I can detect that the outlet is hot using my voltage detector (when the dimmer switch is all the way on), but it pulses. I get about 6-7 beeps, then it skips one, beeps 6-7 more times, skips, continue. My GFCI tester shows an open hot. The outlet doesn't work.  I'm not very experienced with electrical work but this sounds highly unusual to me. Where should I start with fixing the issue?

On my new computer, my fan(s) is/are plain LOUD! Using SpeedFan, I find that my temps are all under 32 degrees C under my normal use (IDK how accurate that is but the CPU itself says 27 C).  The fan doesn't sound unbalanced and it isn't making sounds in rhythm (Not the usual rrrrrrrRRRRRR... rrrrrrrRRRRRR... rrrrrrrRRRRRR... rrrrrrrRRRRRR), just a constant fan. I am thinking about oiling the fans, but I can't decide if it is the PSU fan or a case fan or the CPU fan. If it's the CPU fan I will most likely just replace that with a quiet fan. How can I tell which fan is making the noise (if not multiple)?  One thing that I am thinking may be the problem is my CPU fan isn't PWM so would swapping that out help? There is no "linear voltage" or etc thing in BIOS so I think it may be running at full speed. Also, I could have too much airflow because it is also making a whistling noise that you can hear close to it that sounds like when I accedentially put part of the side cover over my floor vent to get it out of the way.
