How To Check Ac Compressor Clutch

October 26, 2020

Once an electrical current from the on/off switch sends power to the magnetic coil, it causes the outboard clutch to pull in toward the compressor, locking up the pulley and engaging the compressor. If the air gap is too wide, you may be able to correct it by using a different spacing washer.

If the clutch fails, you will start to hear a squealing noise.

How to check ac compressor clutch. Check the ac compressor clutch air gap. Typically a clutch coil should be between the range of 2 to 5 ohms, and any reading below 2 ohms or over 5 ohms indicates a bad coil. I made sure to check the other lead from the coil that is tied to the body of the compressor, that was in good condition mechanically.

If you want to diagnose an ac compressor clutch for defects, apply these techniques: Remove the plug from the clutch coil and activate the a/c system by placing the selector on cold. The ac compressor clutch is the first thing that moves every time you turn on your ac.

If the magnet is good, the compressor clutch will click into place when the magnet powers up. The center part (the clutch) should be engaged and should be spining along with the pulley. Think of it as a switch that is responsible for engaging and disengaging the ac compressor pulley from its compressor drive.

Also, find out whether the clutch and the pulley are spinning. The ac clutch failure can cause another problem with entire systems of your car. It will look like a cylindrical metal piece with tubes and wires running from it.

Perform an a/c clutch coil resistance test with an ohmmeter. Set all air conditioning controls to the max before kicking off the engine. There are times when the clutch of the ac compressor doesn’t disengage.

The price to put a new ac compressor clutch into your car might seem steep, and it might make you reconsider your decision to replace it. The clutch wire felt broken along its length. To check ac compressor clutch air gap, simply insert a feeler gauge between the clutch plate and pulley with the engine off.

Sometimes, when the clutch is worn, the disc is too thin and may not engage properly. As above, check the pressures in the system, and then see if the compressor clutch gets +12v when you engage the switch in the dash. Check the leads to the compressor, the magnetic clutch and operation.

This, in turn, may lead to critical damage to the ac compressor. Check the front side of the clutch to examine its condition. In such a case, the pressures inside build to a dangerously high level.

Compare the reading to factory specifications. The ac compressor starts to work right after the vehicle is started. However, some ac clutches are not adjustable, requiring a complete ac clutch.

If the gap is too large, the clutch coil can’t pull in the clutch disc. Also, when the air conditioner is turned off, then the clutch disengages from the compressor and stops the airflow. When i got home i was checking things under the hood and the refrigerant pressure was fine (pressure according to chart observed in gauges).

Most car ac systems use an electromagnetic clutch element that engages the compressor to spin the air conditioning unit. Ac compressor maintenance the ac compressor doesn’t fail so often, but you shouldn’t ignore its maintenance to prevent it from a possible failure. Now look at the pulley of the air conditioner compressor.

The ac compressor clutch will cost more than $400, while the labor associated with ac compressor clutch replacement will run you right around $200. An easy way to check the clutch of your ac compressor is to gently and lightly tap on the clutch when the compressor is running and the motor is on. Locate the ac clutch relay.

The center part on the pulley of the a/c compressor will not spin when you have the air conditioner off or if there is a problem. Turn the honda engine on. Turn the ac settings to off. open the hood of the honda vehicle.

Trace the wire that runs off the ac compressor; An ac clutch engages and disengages the compressor when your car's air conditioning is turned on and off. The compressor clutch will usually be located under your hood on the left side near the front of your car.

In most cases, the relay is mounted on the fender well or fire wall. Most of the time the clutch not engaging is a result of the refrigerant charge having leaked out of the system to the point where the low pressure switch prevents the compressor from engaging. The relay is mounted on the firewall.

Sadly at over 400 mega ohms the clutch coil has failed. The clutch plate is the black circular piece. This wire plugs into the clutch relay.

The compressor drive hub is usually found at the front of the pulley and is attached directly to the compressor driveshaft. If the gap is too small, the clutch disc may make noise when the ac is off. I was playing with the headlights switch and i started to feel nice cold air then i stop to visually check and sure enough the compressor was working.

The gap between the clutch disc and the ac pulley must be a set distance. How to check oil in ac compressor 1. Today when i was coming back home from work the ac worked.

Release the clutch by removing the positive wire. An ac clutch compressor is a type of compressor that derives its power from the car engine’s flywheel. The compressor clutch consists of a friction plate positioned adjacent to an electromagnetic coil.

Once you turn on the ac the center part of the compressor, the ac clutch should engage and start to rotate with the pulley. I cut past the break and exposed the wire to do a repeat test. Open the hood of your car and locate your ac compressor clutch.

Connect one of the wires, it doesn't matter which one, to the negative side of the battery. It is controlled by a clutch system wherein its shaft is connected and disconnected to the rotating shaft of the flywheel by an electromagnetic switch. When the air conditioner is turned on, the clutch engages with the ac compressor and starts to supply the conditioned air.

An electromagnetic clutch provides the mechanical link between the pulley and the compressor input shaft whenever air conditioning is demanded. How do ac compressor clutch work? To run this clutch compressor, the engine is connected directly to the pump rotor of the compressor using a belt.

To do so, grab a lead from the batter to determine whether the clutch engages. If the battery voltage is present at the plug, test the coil for resistance. Using the 20 volt setting on the dvom, check for battery voltage at the harness connector.

Touch the other wire to the positive side. Check the ac control on the dash.
