I have 01 monte carlo. The fan's are not working. Put a new censor in and relays. The fans are still not kicking on. Ran some code and one was PO 140 and PO 403 any idea what these codes mean?

How can this problem be fixed? What could PO 140 and PO 403 mean as far as these are the two codes I got when I used a scanner on the car? Why would the fans just stop working? Any suggestions?

As far as these codes they refer to the PCM signals to the o2 sensors ,but i don't think they would affect the cooling fans , does the engine overheat ? are you loosing coolant ? one reason the fans may not cut in is if the waterpump isn't working but you would have noticed lowcoolant , do the top and bottom radiator hose's get very hot ?if both hoses very hot and you've changed the sensor etc it may well be the actual fan motors , try putting a direct power and earth to the fan wire connectors , this way you will know if fans are good if they start , then the problem may be in the wiring , which can be a nightmare to trace , hope this is of some help

I googled Hampton Bay Manufacturing and this is what I found:

Hampton Bay fans are manufactured by "King of Fans Manufacturing, FL". The contact number for them is 800-330-3267. ...
Maybe they can supply you with a wiring diagram.

SOURCE: Ceiling Fan only spins 1 speed

assuming you havent messed about with the wireing it can only be the pull cord switch fault or the motor is on its way out

SOURCE: Hunter ceiling fan remote 85095-01 stopped working

it also could be one of the the jumpers fell out of the remote
they are located just above the battery. you will need to match the placement of the jumpers with the receiver mounted in the fan.

SOURCE: Hunter Fan problem

Thge black boxes are capacitors. One is a single and the other is a dual. Evidently the dual runs the two lower speeds and the single run the high speed.

You can test capacitors for basic operation with an analog voltmeter set to Ohms (Rx1 setting is best) by charging up the capacitor with the leadshooked up in one direction, and then reversing them to watch for the slight jump as the capacitor discharges back into the meter... note that this test only works with an analog meter and it must be set to ohms.

This is only a basic test for capacitors and will not indicate if it's withing specs, only that it basically works.

IMO, Hunter is known for having bad capacitors. I've just purchased two fans and already had to swap out the light kits, which contains the capacitors and switches, in one becuse of poor operation and excessive humming noise. since the other fans has the same componenets, other than being a different color, I also thought to try the light kit/capacitor assembly in the fan I've already installed before also installing the second fan.

Guess what, the other set of electircal components with the capacitors runs the fan slower and hums louder.

According to Hunter's web site, humming is a sign of poor engineering in ceiling fans (meaning a power hum rather than a hum from loose components) I agree and Lowes is about to get two Hunter fans back as my three cheapo fans that came with my house do not hum and also the one in my old house did not hum and moved more air.

Even the better capacitor set that I switched out still hums to some degree, so I'm climing Hunter's using **** components, probably becuse their chinese suppliers are screwing them and they're not bothering to keep up the quality control.

Wireing

Temp fan failure could be the thermo temperature sensor. I am not sure of the actual name of it but if you can direct wire your fan and it works, then the fan is good, the sensor is bad. I myself have rewired a switch to them so I can control when and how long the electric fan runs.

I changed the air compressor and the dashboard control panel last year and it has done ok. Now the temp. fan and the compressor fan won't kick in and the air compressor won't kick in also. Checked all...

You say temp fan?If you mean the cooling fans,then the ac is out of freon most likely,the freon has to be in the system,and enough to kick the compressor on,therefore turning the cooling fan on.
