Why does my Ceiling Fan keep changing speed?
Why does my Ceiling Fan keep changing speed?
If the speed remains the same when you pull the chain, there can be several reasons. Chain is disconnected: The pull chain is the weak link in changing the speed. Using the chain many times can weaken it at the connection point until it breaks. Sometimes the chain will pull out of the fan, while other times it will still seem connected.
What happens when a motor fails on a HVAC fan?
This can cause the HVAC fan to not work at all due to motor failure, and it is unable to blow any air out of the vents. This can be highly concerning during especially cold or warm months of the year. Additionally, if the resistor stops working you might notice that the HVAC can only run on one speed—usually a high speed.
What to do when your ceiling fan is not working?
Adding some small adhesive weights to the end of the blades will help bring the fan back into balance for a smoother operation. A motor powers the blades at the desired speed. When it seems like the fan starts to turn hard or fails to keep up a constant speed, the motor is under stress or failing. Replacing the motor is often the only remedy.
What causes a blower fan to not work?
When this happens, you may notice that you will not feel anything blowing out of the vents at all. This may also cause the blower motor to work intermittently. A blower fan is connected to the negative battery terminal (also called ground) on one end and to the positive battery terminal through a blower motor resistor on the other end.

Why is my F150 fan not working properly?
Sounds like your dealer has thrown one too many head units and resistors at it; time to start hunting for the wiring issue between the controller and blower motor. I do notice however that my fan speed dial is a little slow to respond.. I chalk this up to it being a resistance-based switch that’s computer controlled. Hope they get you sorted out!
How to troubleshoot an electric cooling fan problem?
1.Has the Cooling Fan Actually Failed? 1 If the fan comes on when the AC is running at MAX, but doesn’t run when the engine is hot, check the temperature sensor… 2 If the fan fails to come on, first check for a fan blown fuse or triggered breaker. On older vehicle models, you may… More
