- In this video I show you how to test your A/C clutch coil, using 3 different methods. What is a Clutch Coil - A unit consisting of many windings of wire fastened to the front of the air conditioning compressor. When current is applied, a magnetic field is set up that pulls the armature into the rotor to engage the clutch. Also known as clutch field.

Thank you very much! Very useful video!
Glad it was helpful!
Good job sir tngks
Hi very good video having some issues with my ac clutch keeps short cycling the freon is good the pressure switch is working.
Hello,
In an A/C system there are many variables that can lead to a fast cycling of the compressor. To better assist you, when you have the A/C gauges hooked up to the low and high side with the car running and A/C on, how low does the low side gauge go down before it cycles? And also, how high does the high side go up before it cycles? This will give me a better idea of the health of your system so I can further help.
Without this info I could send you in the wrong direction.
Thanks for watching.
Thanks for explaining the complete mechanism in a very clear way, is it normal to hear sound every time when electromagnet pulls in metal or it depends upon design ?In my car i hear it every time but i dont hear it my friends car when A/C is on
This is a very good question. I have noticed on some model vehicles the sound is quieter than others. I would say its due to the design of the compressor clutch coil combo. Even though it's quieter, I have been able to hear an audible click or smacking sound. But there might be another design that I'm not aware of that operates very quietly. If you don't mind me asking, which make and model vehicle does your friend have? Maybe I can dig up some info on the type of A/C system that's in his vehicle.
Thanks for watching!
Thanks again for taking your valuable time to reply.My car model is Honda Jazz 2015 model .My friend's car is Peugeot 208 Diesel engine, i recently recharged A/C gas for and noticed that clicking frequency is lower now, is it because compressor has to work for less time or less loaded now?
@user-mz7nk5wo6v I would like you to imagine a pump. This pump has a suction side where it pulls freon and a pressure side where it pushes freon. This pump is your A/C compressor.
Now, this pump has two switches. One is for the suction side called the Low Pressure switch and one is for the pushing side called the High Pressure Switch.
These pressure switches help your A/C system work properly. Basically, they turn on and off your compressor clutch coil.
So, when your compressor is working, it will start to push freon throughout the system.
But if it's low on freon, the low-pressure switches will turn off the compressor until there's enough pressure to turn on again.
Think of it like a sweet spot that the system tries to maintain.
So when you added more freon gas into the system, you have helped it. Now, when the pump runs, the pressure on the low side doesn't go low right away and the compressor turns on and off less.
I hope this helps 🙏
Later on, I'll make a video on this subject.
And you're welcome. I'm more than glad to help
What happens with when you try to activate the clutch by turning the ac on inside the car when there is no refrigerant in the airco system?
Does the clutch engage and the airco pump is destroying itself
Or
Is there a built in safety in all systems so the ac pump is not engaging when there is no refrigerant in the system?
Good question, yes there is safety system in place.
The low-pressure switch is wired into the electrical circuit to prevent the A/C compressor from turning on when there is low pressure or no refrigerant. You can bypass the switch just to test the circuit.
But you should only do this for testing. Just like you motioned the compressor will run until it destroys itself. (I have seen this happen before)
Also, there is a high-pressure switch as well. This prevents the system from building too much pressure. Together these two simple switches play a very imported roll in our A/C system.
Thanks for the question this subject will make a great video!
Where did you turn your multimeter to? How did you set you set your multimeter for testing ac compressor
Set the multimeter OHM (Ω)
