It might be the way your wiring it up if your pluging it in to an outlet make sure your white wire's are connected . First buy your self a voltage meter make sure you dont have to many amp's coming in that will burn out your motor.if u need more help send back info on how you plug it in and the volt's and amp's coming in thank's

The 123.5 volts your meter is displaying is a little high. Typically, 110 - 120 volts is the expected amount - but you're within a few percentage points so it shouldn't be a problem. Is the wire from the outlet to the fan something you ran - or was it already there? Either way, what is the size of the cabel? Typical identification would be "SJOW" (or other insulation type indicator) followed by the wire size and number of insulated conductors such as "16-3" or "14-3".

The amount of current in amps required by the fan should be printed on a label on the motor somewhere. This label should also have the voltage(s) needed to run the fan, too. It is not unusual for motors to have dual voltage ratings such as "120 / 240" volts. If it has 2 voltage rating it will have 2 current ratings too such as "9.2 / 4.6" amps. The higher current rating is for the lower voltage. When there are multiple voltages listed, this means that there are multiple ways of wiring the motor. It may ship wired for the higher voltage, in the example that would be 240 volts. Supplying only 120 volts to the motor will cause it to over heat and fail prematurely. make sure the voltage supplied (120 volts) is correct for the way the motor is wired.

Typically 14-3 cable is good for 12 amps and 16-3 cable is good for up to 8 amps. Make sure the wire is sized large enough for the amount of current the fan needs. Replace it is it is too small.

Lastly, this wiring is severly substandard and there are numerous electrical code violations that should be corrected before powering this up again. I understand that you're just trying to make it work, but it is very dangerous to leave terminals & connection in free air - and easily accessable to anyone to come into contact if a wirenut should fall off. I suggest that you call a qualified / licensed electrican to complete this job for you and your family.
Good luck!

    this is a 10" exhaust fan on the panel says 120v 60Hz 0.38A so what wire you think i need but i think the fan might be defected

I have a 2000 Bmw 323 I that is having a overheating problem what would be the cause of the overheating problem a thermastat a water pump or a radiator flush


Could be any or all three or a bad cooling fan. I'd start by replacing the thermostat since they are dirt cheap. After replacing the thermostat warm the vehicle up and feel the upper radiator hose if its hot the rhe thermostat opened and the water pump is circulating coolant next check the radiator it should be hot near the upper radiator hose and significantly cooler near the lower with an even heat distribution if any parts of the radiator dont get warm/hot then you radiator is plugged. Also you need to check the operation of the cooling fan with the engine warm turn on your ac that should immediately turn the electric fan on

I've had my Carriage House II ceiling fan for three weeks. Yesterday when we turned the light on it stayed on for a second or two and shuts off. It now does that every time we turn the light on. Even...


Check the bulb(s) to make sure they are screwed in securely. If it happens only when the fan is on, there may be a loose wire up in the housing, where the light fixture attaches to the fan. Perhaps, a wire nut is loose. If the light and the fan switches are wall mounted separately, the wall switch for the light may be bad.

Warm Fridge side


Defrost the fridge freezer overnight. Restart unit. If it starts working you have either had a door ajar or a defrost problem. If it fails to cool down at all then you may still have a defrost problem or a evap fan motor faulty. Most likely outcome is that the unit will work once defrosted for approx three weeks after which the freezer will freeze back up. Most likely cause will be the defrost heaters. Any good tech should be able to help on second failure. Hope this helps.
