If it's not the fuse, the fan thermostat may have gone bad. This is a separate thermostat from the radiator coolant system thermostat even though it contacts the coolant. See if there is an accumulation of minerals on the coolant side of the thermostat. Cleaning it off may help. Depending on the setup, the voltage or resistance of the thermostat changes significantly at the specified temperature.

How to use the battery disconnect switch correctly


The battery isolator switch, where one is fitted, can be to increase vehicle security or to help prevent vehicle battery discharge if it is left unused for long periods.

However it is wired the battery switch must never be used while the engine is running.
Isolating the battery when the alternator or generator is producing current can cause a voltage surge that is capable of destroying every bit of electronic equipment fitted to the vehicle.

Best practice is to isolate only after the engine is switched off and stopped turning. If an electric cooling fan is fitted the engine should be allowed to cool a little before isolating.

I CAN 'T GET THE COOLING FAN TO WORK BY IT'S SELF


The fan can be driven by a drive belt off of the crankshaft or it can be operated electrically. Regardless of the design used, inspect the fan blades for stress and cracks.
Electric fans are also inspected for damage and looseness. If the fan fails to turn on at the proper temperature, the problem could be the temperature sensor, the fan motor, the fan control relay, the circuit wires, or the controller. To isolate the cause of the malfunction, attempt to operate the fan by bypassing the control. On a computer-controlled system, this can be done by using a scan tool to activate the fan. If the fan operates, the problem is probably in the coolant temperature sensor.
It is also possible to check fan function by jumping the fan relay to attempt operating the fan motor. If the fan operates, the relay may be the faulty component; however, additional tests will have to be performed on the control circuit of the relay.
A jumper wire can also be used to jump battery voltage directly to the cooling fan. If the fan motor fails to operate, check for proper ground connections before faulting the motor.
To direct air flow more efficiently, many manufacturers use a shroud. Proper location of the fan within the shroud should be at lease 50 percent inside the shroud. If the fan is outside the shroud, the engine may experience overheating due to hot under-hood air being drawn by the fan instead of the cooler air. If the shroud is broken, it should be repaired or replaced. Do not drive the vehicle without the shroud installed

Hi, I have a goldStar GA 1866VHR split Airconditioner, (5050w cooling and 5040w heating capacity). Today I noticed that compressor/condenser unit was still running after I turned off the aircond: from the...


Thanks for your detailed information. But solution is very simple. The compressor contactor in out door unit. Struck. And hence, when you power on, without indoor commanding, the out door starts running.

Replace same type Contactor relay (In out door unit) immediately. Hope, it's helpful.

AC won't start. Fan runs


Depending on make & model, usually if you hear a "click" at control box at ceiling when switched to cool, that's a good indication of a faulty relay, capacitor , or maybe even compressor. Not something to play with if not experienced, especially capacitor. Have someone who knows electrical troubleshooting check voltages at compressor and you should be able to back-track from there and isolate problem. If no clicking at ceiling when asking for cool, check thermostat, then control box connections etc at ceiling. Need more info such as make and model number as well as thermostat type if more questions please.

Radiator fan cycles continously. Fan radomely comes on and off frequently and has consistently gotten worse. Because of intermittent problem, Mazda was unable to diagnose problem. Any advice would be...


First, intermittent problems are the worst! I would look for a bad or loose connection. Does the fan ever run consistently? If you turn on A/C most cars will run fans continuously, if yours works ok on this setting then problem is isolated to temp control (fans ok, wiring ok, relay ok) The temp switch would be probably be faulty (or connections). If your fans cycle even on A/C setting then you are looking at a complete electrical inspection. Switches, wiring, fuses, connections, relays, fans...everything! Hope this helps and good luck!

1992 Ford Taurus with a 3.8l V6 the cooling fan


The Taurus has Two temp sensors. One for the dash, which is isolated, then one for the PCM, it also controls when the fan relay should actuate. Its a 2 wire sensor, just above the thermostat. If you remove the harness from that sensor, and the cooling fan comes on, at any temp, (should take 5- 10 seconds) then thats your fault.

Cooling fan does not come on at all...


Hi ,I posted this problem as well (ROYP75) I fixed the problem by replacing the printed circuit board(this amongst other things controls the fan speed).If you can remove and replace self tapping screws and replace wires like for like on the circuit board you can do this.Isolate from gas and electric, remove oven back taking care with fan wires, wires connected to circuit board and fan connected to oven back once removed you will see circuit board and from their it's just a case of swapping parts .circuit board was purchased from espares .co.uk part no es660722 hope you find this helpful

Power running through neutral wire


If you are getting power on the neutral that usually means the neutral is open (broke). To confirm this check the voltage on your 2 hot leads. You may need to check the voltage when the oven is on. You may find high voltage on one leg and low voltage on the other. The high voltage would fry a fan (so would low voltage for that matter). I hope this helps. Sorry I don't know more.
