Can a low refrigerant level cause the AC compressor to not turn?
Motor running, AC on max, fan on high. Clutch on compressor is not turning. Did not want to charge the system if there is refrigerant at the correct level. Checked the fuse and it is good. Most of the time this is sign of low freon. 9 people found this helpful. Then it is likely OK to charge the system and then the clutch should engage?
What to do if your a / C compressor won’t engage?
HOWEVER, if you cannot turn the compressor on, you cannot recharge your AC levels (grrrr). So you need to use a paper clip to bypass the relay switch and force the clutch to engage. You can then recharge the freon and re install the relay switch and it will sense more pressure and the clutch will engage by itself. Loading…

What to do when your air conditioner won’t take Freon?
If the compressor clutch shoe is not rotating, but the pulley is, then you can unplug the electrical connection on the low pressure switch and put a jump wire into the harness jumping the connection on both terminals. This should engage the compressor clutch.
Why is the Freon low on my AC compressor?
The low-pressure switch will prevent the AC clutch from being engaged, and the compressor will not spin. This prevents the compressor from engaging. The major reason the Freon is low would be due to leakage. Once you refill the Freon, check for any leakages to prevent the problem from reoccurring.
Why is the AC clutch not engaged when the Freon is low?
No, the AC clutch will not engage when the Freon is empty or low. The low-pressure switch will prevent the AC clutch from being engaged, and the compressor will not spin. This prevents the compressor from engaging. The major reason the Freon is low would be due to leakage.
Can a refrigerant be attached to an AC compressor?
If your AC is compatible with an R134a refrigerant, attaching it to your unit will overrule the low-pressure switch. This will result to a normalized function of your AC compressor clutch. If your AC isn’t compatible with the R134a type and is actually an older model, consider jump-starting your clutch.
No, the AC clutch will not engage when the Freon is empty or low. The low-pressure switch will prevent the AC clutch from being engaged, and the compressor will not spin. This prevents the compressor from engaging. The major reason the Freon is low would be due to leakage.
What happens when the Freon level in your car is too low?
The AC clutch will fail to engage since the level of Freon is too low for the compressor to pressurize. But that is a sign that might not be so obvious. The good news is that your car will exhibit other low refrigerant symptoms. Here are some of them.
Why does my air conditioner not pump refrigerant?
When power energizes the clutch coil, the magnetic field pulls the clutch in to engage the compressor shaft. If the clutch doesn’t engage, the air conditioning compressor can’t pump refrigerant. So start your diagnosis by determining if the compressor clutch works. Turn the air conditioning controls to MAX AC and start the engine.

Why do air conditioners need a low pressure switch?
Air conditioning compressors need a constant supply of oil to prevent catastrophic failure, and it’s the refrigerant that carries the oil through the system. That’s why car makers install a low pressure switch–to prevent the compressor from running if the system is low on refrigerant.
What happens when Freon is low in an AC system?
Freon evaporates after it is added to a car’s AC system which keeps the car cool, and it turns into a fluid as soon as temperatures begin to rise which enables it to cycle through the AC system. The car’s AC system won’t be able to maintain temperatures as low as it normally would if the levels of freon are low.
What does it mean when your AC compressor does not spin?
It is an ominous sign when the clutch engages but the compressor does not spin. Changing the compressor clutch could be the only solution in this case. A bad AC compressor clutch needs immediate fixing. A delay can cause serious damage to the air conditioning system and the engine.
What happens when the Freon level in the AC is low?
When the Freon levels are low, you will detect the presence of bubbles. If you don’t see any movement, then there is no Freon in your car. A functional car AC unit with optimal Freon levels will blow cold or hot air according to what you set the AC on.
HOWEVER, if you cannot turn the compressor on, you cannot recharge your AC levels (grrrr). So you need to use a paper clip to bypass the relay switch and force the clutch to engage. You can then recharge the freon and re install the relay switch and it will sense more pressure and the clutch will engage by itself. Loading…

What happens when the Freon level in the air conditioner is too low?
If the Freon levels are too low, the clutch will fail to engage which means there’s not enough refrigerant for the compressor to pressurize. In other words, your air conditioning system has nothing to work with!
How does a car air conditioner use Freon?
Before the Freon is converted into a liquid in the high side, it starts out as a gas in the low pressure side of the system. The vehicle is kept cool by the constant circulation of refrigerant through the high and low pressure sides of the system. Overtime, these pressurized systems begin to leak! As with any mechanical system, time is an enemy.
Why is my air conditioner not working in my car?
How your vehicle’s air conditioning works. The Texan heat is tough on air conditioning systems, and during the summer months, the last thing you want is to head out for a long drive only to realize your vehicle’s air conditioning is not working. The chemical (refrigerant) used to provide cool air is called Freon.
What are common reasons my Chevrolet Cavalier has air conditioning problems?
What are common reasons my Chevrolet Cavalier has air conditioning problems? While there are a variety of reasons your Chevrolet Cavalier air conditioning won’t work, the most common 3 are a refrigerant leak, an electrical climate control issue, or a problem with the air conditioning compressor.
What causes an AC compressor to not engage?
If the clutch doesn’t engage, the problem could be a blown fuse, an open in the wire to the clutch coil, a bad clutch coil, a poor ground, or a low pressure lockout. AC compressor clutches receive power in a number of ways. They can activate through a relay that’s energized directly by a proper condition of the low and high pressure switches.
What happens when the radiator fan is not running?
The radiator fans will cause the refrigerant to condense and turn back into a liquid. It won’t be under pressure since the compressor isn’t running. But chances are some of it will still reach the orifice tube and flow into the evaporator coil. With the blower fan running, any liquid that enters the evaporator will boil and turn back into a gas.
