2004 Venture Chevrolet minivan cooling fan circut


Are you talking about the radiator fan? How hot does the engine get in degrees F? Some makes and models, the radiator fan won't turn on till about 220 degrees F. Check for applicable trouble codes, see if any code that refers to the radiator fan circuit or coolant temp sensor? Some of the national brand auto stores will check codes for free.

Of course, as far as overheating in general, you have the thermostat--water pump and other possible issues. Are you losing coolant?

I got toshiba nb205 as i get error A PROBLEM WITH COOLING SYSTEM HAS BEEN DETECTED RETURN IT FOR SERVICE IMMEDIATLY i get its fan changed now its fan is in running condition and i am also using cooling pad...


hmmm, you could try booting into bios (hitting del key at bootup) and see what the internal temp readings are. Laptops have tricky cooling schemes that usually rely on one fan and heat pipes. If I were you I would backup my data and take it to a qualified laptop repair shop.

Thermo set "heat" and "Auto


Check the fan relay. These relays are used to cut the fan on and off when the thermostat is set in the air conditioning or heating mode or when you move the thermostat to the "Fan On" position. The low voltage usually the green thermostat wire is wired to terminal #1. The low voltage common wire to terminal #3. One line voltage wire is attached to terminal #4. The high speed blower wire usually black is attached to terminal #2. When the thermostat calls for air conditioning or "Fan On" the 24 volt coil is energized, the terminals 4 and 2 close. This causes the fan to come on in high speed. When your home cools down and the thermostat cuts the air conditioner off, the low voltage coil terminals 1 & 3 are denergized, and the fan goes off. Sometimes these little relays stick which causes the fan to run all the time or will not make good contact, which causes the fan to not run in the "Fan On" or air conditioning mode.

My whirlpool refrigerator (Model ET18DK) does not cool


Most likely one of two conditions are the root of the problem. Either the fan in the freezer is stalled or the defrost system has failed. The fan in the freezer should run any time the comressor is running; if it's not, there's your problem. If you can hear the fan, check for frost or snow developing across the back panel in the freezer. Local repair service could probably supply replacement parts quickly for defrost failures (most likely a bad terminator if defrost system isn't working).

LG LSB24X1RPL1 split a/c compressor fan not working


It is probably the control board but you will need to use a volt meter to check for voltage leaving the harness that goes to the fan. Make sure that the unit is calling for the comressor to come on. If it isn't, then it's probably the board and if it is, then the motor may be bad.
