What is a thermo control amplifier?
From what I gather, it is a device that protects the evaporator in Nissan and some other automotive AC systems from freezing up. The device is a transistor switch component driven by voltage or current derived from an integral thermistor. Colder/Freezing temperatures cause the circuit to open and through the ECM and Air Conditioner Relay stop the compressor. The unit used by Nissan works as follows: As the temperature is decreasing the circuit opens around 38 to 37° F to turn off the compressor. There is a one to two degree hysteresis in the unit to prevent rapid cycling of the compressor. The device closes the circuit when the temperature reaches 39 to 41°F.
1989 XJ6 - Circuit One Failure Replaced fuse fan ac compressor and still get blown fuse wcircuit one failure occurring Anyone know why or how to fix?
fuses blow because their amperage is exceeded. you have a short somewhere, or the coil on the ac compressor is drawing too much current. DO NOT PUT A HIGHER RATED FUSE IN PLACE OF THE OLD ONE!!!!!!!!!!! that will cause more problems (such as a fire) is you have a wiring schematic, you can unplug all items less one, and try that until the fuse blows. you can also try to splice in fuses (of the correct amperage) in various points in the circuit if the wiring is hard to trace.
What happen when two of four diode in a bridge rectifier is short circuit?
You will get reduced amperage (or output) from the alternator. A alternator rated at 80 amps would probably only produce 50-60 amps. If a diode in a rectifier is shorted, then the alternator output would be greatly reduced or possibly no output at all.
What statement descibes the flow of electic current in an AC circuit?
The flow of electric current in an AC circuit is alternating, it flows one way then the other, with reference to ground.
Which color wire is the hot to the AC compressor on a '99 Chevy Suburban?
The Dark Green Wire should be the hot to the air compressor clutch and Black should be ground.
What is code 33 on 95 Jeep Cherokee and how to fix ti?
ac clutch relay open or short circuit
What is the compressor on a 2001 Dodge Ram?
The ac compressorThe ac compressor
Why don't AC input wires to a transformer just short circuit?
The resistance of the winding in the primary of a transformer constitutes a load. As long as there is resistance then there is no short circuit. A short circuit is considered no resistance which develops an instantaneous high current. That is why fuses and breakers are inserted into the circuit to open the high current flow under a short circuit condition.
No power to ac compressor only power to everything else 2001 escort zx2?
Check under the air filter housing for the PCM (power control module) if you could open it you would see about 5 relays on a circuit board one of the relays is for ac compressor. In general change the PCM.
How do you fix ac drier?
There are eleven steps on how to fix the A/C drier. Some of the step-by-step instructions are turn off the AC system's condensing unit circuit breaker, open the condensing unit's electrical panel and its compressor cover, and then inspect the compressor's capacitor that is located in the condenser's electric panel.
Can a 600VAC switch be used if a 600VDC switch in unavailable?
No. An AC switch cannot break the arc that occurs when you try to open the DC circuit. In an AC circuit the switch just handles the arc for a short period of time until the voltage reverses.
Why does your ac on your 1993 infiniti j30 blow hot?
Idle the car with the AC running. Open the hood and look at the AC compressor- is the compressor engaged? (the front of the compressor (inside the belt) should be spinning. If not, then have the AC system recharged. If it is turning, then you've got the door to a duct stuck inside the unit.
What would cause my 2006 kia to not get power to the ac?
well, out of freon in A/C, because the pressure sensor not being energized. then a bad fuse on the A/C circuit, followed by open clutch on A/C compressor.
What is the name of the very top pulley that you see when you open your hood on 1999 dodge Dakota sport?
The ac compressor is the larger one, the alternator is the smaller one.The ac compressor is the larger one, the alternator is the smaller one.
Why does the AC not turn cold after you installed one can of R134 and it reads in the Blue which shows full for a 1995 Ford Contour What can you do to get cold air again?
If the AC compressor is engaging it could be the heater control valve is stuck open. If the AC compressor is NOT engaging you probably have a problem with the controls, a sensor or the compressor.
When you turn the air on in the car it blows the fuse why?
this is because you have a short in either the the ac circuit or the fan/blower circuit. You'll know know which one by turning the fan on without the ac, and if it doesn't blow the fuse then you know it's the ac circuit.
When you turn on your ac the fuse blows out?
Compressor is more than likely locked up or you have a short in the wiring.
