My Car Starts to Overheat What Could Be Wrong?

Overheating is caused by anything that leads to a loss of coolant, prevents the cooling system from getting rid of heat, or causes excess heat in the engine itself: Coolant leaks (water pump, radiator, heater core, hoses, freeze plugs, head gasket, engine internal). Weak radiator cap (does not hold rated pressure and allows coolant to boilover). Pressure test the cap to check it out. Cooling system clogged (deposits built up in radiator or in engine due to maintenance neglect or use of hard water). Use a cleaner, then reverse flush the system to clean it out. A badly-clogged radiator may need to be rodded out or replaced. Thermostat stuck shut (replace). Inoperative electric cooling fan (check fan motor, relay and temperature switch for correct operation). Bad fan clutch (replace if slipping, leaking or loose). Missing fan shroud (reduces cooling efficiency of fan). Slipping fan belt (tighten or replace). Too low or too high a concentration of antifreeze (should be 50/50 for best cooling). Bad water pump (impeller eroded or loose - replace pump). Collapsed radiator hose (check lower hose). Debris in the radiator (remove bugs and dirt). Late ignition timing (reset to specs). Restricted exhaust system (check intake vacuum readings and inspect converter, muffler and pipes).

1. What are some things that use electric motors in a school?

if any of your classrooms have the blinds on a motor, or the white projector screen on a motor. fan motor in the projector fan for the HVAC system

2. Can a bad inducer fan motor prevent a furnace from igniting?

Ralph gives you a good test for the combustion blower. it absolutely has to be working for the furnace to work, it is part of the ignition sequence. We are missing the other half of the code. Bryant has a two digit fault code. Read the chart on the door panel or the installation book. It could be stuck fan blade, too, but you will have to remove it to find out, or tap on it to free the blades.

3. my a.c is not working little air is coming out the vent and the fans blades on the unit outside is not spining

The fact that your outside unit, called the condenser which contain the compressor, condenser coils and the cooling fan is not running should not make any difference in the amount of air you get through your vents. The inside part of the system consists of the evaporator and the blower. Of course if the outside system is not running, the air that comes out will not be any cooler. The thermostat should operate both systems by sending a current to relays in each system which in turn supply current to the compressor and fan motor on the outside and the blower motor on the inside. It is possible that the relay is not receiving current from the thermostat. If you have outside dogs check to see that the wires are not chewed in two. Of course it is possible that the fan motor is defective since it is exposed to the elements. Try spinning the fan to see that it turns freely. When a relay energizes it will make an audible click, so if you have someone operate the thermostat while you listen you should hear it operate. If at this point you find the things that are not wrong you might re post your question stating your findings and someone might give you some other possibilities. ...Good Luck

4. We have a 2002 model GE Refrigerator which is not cooling properly. The motor and compressor are both running.

The serviceman was right, since there is no frost on the evaporator, so it must be undercharge of refrigerant or loose compression of the compressor. Dont worry why he did not open the circuit board because as you had said the compressor and fan motor are both running

5. Whats the computer fan motor called?

Power Supply Unit

6. How do I tell if my air conditioner has a faulty fan motor?

the fan would not work properly, make noise etc, but for speed issue more often is more often a resistor fault, so best to check at full voltage

7. Heat/Air conditioner in my car is not working properly...?

fan motor is probably burnt out

How Do I Rewind a Ceiling Fan Motor?
Umm, an electric motor is not a clock, nor does it have a mechanical drive system like a clock so no, you can not "rewind" an electric motor. You can turn it backward or forward by hand but you wo not accomplish anything nor will you do any useful work1. What would cause a fan MOTOR to run BACKWARDS?Be careful, running a condenser backwards may cause damage. If it is a 3 phase induction motor you can reverse the rotation by switching any two of the three wires. If it is single phase then the motor usually has a third wire that will reverse rotation.2. Direct replacement for A/C Condenser Fan motor?Go buy a universal fan...It's going to last a long time for the 1/3 of the price. I would not pay over $75.00 for that size of motor. You will find out GE has went China too, and that motor will be no where the quality that your 15 year old motor is3. AI am replacing a condenser fan motor in an old Lennox unit.?This type of modification is hard to determine and give you advise unless a physical verification is done. For this one, I am afraid that you will need to call one of the money hungry heating techs in you city. Good luck...!4. need a schematic or info for wiring for a T35696-HP cooling fan motorJust use a brushless motor ESC (electronic speed control). Black wire not needed. I believe the ESC needs to be at least 30 amp or higher. I will be using a 30amp5. Are there general guidelines to attaching a rotor onto the output shaft of an electric fan motor?i am no longer an electric engineer, yet out of your description of the project, i will see no reason purely the tip of the rotor ought to warmth up. the only way this could ensue is that if the rotor have been improperly proper to three form of mechanical load, like a equipment or flywheel. Vibration could reason friction to warmth the element to touch. If the motor is not proper, it is very bizzare. possibly you have got here across a sparkling ability of producing warmth power making use of magnetic flux and a sturdy steel shaft. Artificially elongate the shaft and notice if the temperature maintains to upward push because of the fact the dimensions will strengthen. If the motor continues to be purely drawing 5.5 KW, this ought to be some unusual form of container result6. I have replaced my a/c condenser fan motor but didn't put the oil in it I bought the oil a put in it but it.?Probably. It is not low on freon is it?7. What will happen if I try to run a 7.5mfd fan motor with a 5.0 capacitor?you worded the question a little confusing, but the bottom line is you have to have the right size capacitor for the right motor or you will cause damage to the motor8. how do I test a fan motor of central air unit?If the motor in question is the cooling motor for the condensor outside, it is simple. First a little troubleshooting tip. Check the fuses if you are thinking the motor is bad, but just replaced it. If you replaced it with a used motor make sure the phases are correct. Residential uses single phase so I am assuming it will be residential service. Make sure you didnt put a three phase motor in its place. OK shut off the thermostat, shut off the power to the unit. pull the cover off the unit and check for any loose wires, burn marks, blown fuses, ground, anything unusual. If it all looks good find the relay that controls the motor. It will either be a "ice cube relay" or a manual relay. Ice cube relays look like a little clear box with a small control relay inside. Manual relays will be open,usually with 2 to 3 copper poles showing, in which case you can take your plastic screwdriver handle and push it in momentarily, after you turn the power on, to see if the motor turns. If it is a ice cube relay consult a electrician for the proper jumper setting to bypass the relay. Yyou can always do it the old fashioned way. Take the motor back out and propely hook it up to a external power supply of the same voltage and see if the motor turns. Whatever you do, be careful with electricity, it is not the voltage that kills you, its the amperage. If you do not feel comfortable doing it - DON'T. Good Luck!
