How regulator control the speed of fan?
Fan regulators are similar to light dimmers. Their function is to control the speed of the fan. The regulator uses resistances for the speed of the fan. It acts as a divider and the speed changes based on the resistance.
Fan speed controls not working on a citroen dispatch van why?
no need to check, just replace the whole fan that has a little control module in the fan itself to control the speed as well
Where does the power wire from the fan motor on a 1994 Ford Escort LX connect to the fan control switch?
There is no fan control switch, and no direct connection to any sensor or switch on that vehicle. The system works like this. The computer(PCM) decides when to turn on the fan. The PCM looks at engine temperature from the ECT sensor, and AC input from the AC control head switches. When the PCM decides that you need the cooling fan to come on, it uses the cooling fan relay, and the cooling fan high speed relay to turn on the fan, and whether it should run at low speed, or high speed. The power input to the cooling fan comes from the cooling fan relays.
How to repair a 2001 Jeep grand Cherokee dual climate control system where there is no air flow through the system?
If you do not have air flow in the system, probably your fan controller is not getting any juice, to check look under the glove box in the passenger side, you will see a black box bolted to the HVAC module, there is a 3 wire plug that runs to it and 2 wire plug that runs from it to the fan motor, the 3 wire plug has ground wire on one external side, positive wire on the other external side and signal wire from the dual climate control to set fan speed, the biggest issue I've seen with these fan speed control module is that the positive feeding wire over heat and melt, the spade solder in the receptacle, so a good sound connection and resolder is the solution unless you have damaged the board.

Why does a fan only work on high?
More information would be needed to diagnose your problem more accurately, but here are some tips to start: 1) Fans will not work with dimmers. If you have a dimmer controlling your fan, it will only work when the dimmer in is the full intensity position (if at all). You will need to replace the dimmer with a fan speed control. If one switch controls both the fan and the light, this will not solve your problem, as a light will not work with a fan speed control switch. You will have to settle with a standard single pole switch, a remote switch, or get one more wire between the switch and the fan. 2) If you have a fan speed control switch, but the fan doesn't seem to respond as it should, you may want to pull on the pullchain directly on the fan. If the pullchain is not set to high, your speed control will not work correctly. 3) If #2 or #3 don't apply to you, and you are simply using the pull chain on the fan, you may have a bad switch inside the fan housing, loose or disconnected wires to the fan (unlikely), or simply a bad fan motor.
How the pedestal electric fan working?
1. Insert the power plug into a 110 or 220 voltage ac power outlet.2. Switch Control: To turn on the fan, simply push any of the speed control buttons: 3=High speed; 2=Middle Speed; To turn it Off, push the “O” button.3. Tilting Adjustment: Always switch the fan off before making a tilt adjustment. The air flow can be adjusted upward or downward by movingWorte by WWW.QIFACN.COM
How do you wire a new 110 stove vent fan to another vent fan downstream and still use the switch on the new stove vent?
Please note that if you have to ask a question like this then you probably aren't qualified to do electrical work and for your personal safety I suggest that you find someone that is to do the work. That being said a qualified electrician would land or splice your wire on the line side of the existing fan switch. The existing fan switch won't control the new fan but the new fan will be on the same circuit. This is called wiring in parallel.
How does a citroen C4 2005 control the heater fan speed?
A device known as a resistor block has coils of wire. each coil has windings that are larger and larger to provide faster and faster fan speed. a fan speed switch directs current to the appropriate coil and the output voltage changes the fan speed. Since coils generate a lot of heat, the resistor block is normally found mounted on the heater/ac box or ducting to allow moving air to keep it cool.
