Why is fan continuing to run after the motor is off on your 1989 Cadillac El Dorado?

Fan is controlled by temperature regardless whether car is running. So, fan will continue to run until thermostat reaches the desired temperature. It is normal. HTH


Will a motor shut down if the run capacitor fails?

If a motor is running when the cap fails it will probably continue to run at much higher amp draw and most likely shut down on thermal overload. It can start with a bad cap, but in my experience it most likey wont.

Why does your bathroom or kitchen extractor fan run when the switch is turned off?

If the fan does not go off after 2 hours from switching it off and you know that the fan unit has a timer, then it is likely that the fan unit has either recently become faulty (if you know that it always went off before) or, if it is a new fan, that it has been wired up incorrectly. A fan unit which has a timer in it must have two separate "hot" wires feeding it:A "non-switched hot", which is permanently fed with power from the breaker on the main supply panel. After the fan has been switched on using the "switched hot" wire described below, this "non-switched hot" wire keeps the fan running for the length of time the timer has been set for.A "switched hot" wire which should be connected to the on/off switch that controls the fan.Depending on the actual design of the control circuitry inside the fan unit, if the above two "hots" have been connected to the fan unit the wrong way round, the result can be that the fan will "stay on and running" all the time, regardless of the position of the on/off switch for its circuit.The solution is to switch off all the power at the main breaker panel and, after you have checked that no wires are still "hot" or "live", re-wire the "hots" on the fan unit the other way round:You must ensure that the "switched hot" connection on the fan unit is no longer connected to the permanent hot feed wire coming from the breaker on the main supply panel. (It should now be connected to the switched hot wire from on/off switch that controls the fan.)The "non-switched hot" connection on the fan unit isconnected to the permanent hot feed wire from the breaker on the main supply panel. (Instead of to the switched hot wire from the on/off switch that controls the fan).More details:If the fan stays on after it has been switched off there is probably a timer inside the fan unit which will turn the fan off after a set time. If the fan does not go off after 2 hours from switching it off then either the fan unit has no timer but has been wired up incorrectly - so that it is not controlled by the on/off switch (see above) or the timer may have been set to stay on continuously.Sometimes a fan may come on when the switch for a light in the same room has been turned on but, if the fan has a timer, that timer will keep the fan running even after the light has been switched off.Sometimes a fan may have its own on/off switch, separate to another switch controlling a light in the same room. In that situation you might switch off both the light and the fan but, if the fan has a timer, the timer will still keep the fan running even after the light has been switched off.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.

Cooling fan sometimes wont cut off?

With many cars now days, the fan may continue to run after the car is shut off, or they may even start and run for a while after the car is shut off. An engine will actually get hotter for a short time after being shut off. Sometimes that will trigger a sensor to turn on the cooling fan. If it continually runs after being shut off, it could be a faulty temperature sensor, or a faulty fan relay, or even a bad computer.


Why won't the radiator fan on 2000 dodge caravan turn off?

If it is an electric fan, it may continue to run after the engine is shut off until the engine temperature drops below a certain point. This is normal and the fan should shut off after a while (definitely not longer than 20-30 minutes after the engine is stopped). If the fan continues to run for hours after the engine is shut down, then there is a problem that needs to be addressed. Disconnect the battery until the vehicle can be serviced.

The car has an electric cooling fan that is temperature controlled. The fan will sometimes run for a while after the car is turned off to help cool the engine. If the fan doesn't stop after 20 minutes, then you can start looking into problems with the relay, or the coolant temperature sensor.
