What causes car AC compressor to turn on and off?
Short cycling, when the compressor constantly shuts on and off, is one of the most common air conditioning problems. Several conditions cause short cycling, including a faulty or obstructed thermostat, leaking refrigerant, icy coils or an HVAC system that is too big for the building in which it is installed.
Why does the AC compressor turn on and off?
When your refrigerant is low, the needed compressor-pressure levels are affected. This triggers your compressor’s low pressure control, shutting off your compressor. When the pressure rises and triggers your AC to restart, this causes the short cycling.
Is the a / C working on the Toyota Camry?
This article applies to the Toyota Camry (1997-2011). A working A/C is one of the most basic, but essential, features in a car. It can make the difference between a delightful drive and a sweltering and miserable commute, so it’s clearly a high priority to fix.
Can a / C compressor fail on a Toyota Camry?
Although highly unlikely, it is possible for the A/C compressor to fail from general wear and tear. It’s very hard to diagnose this yourself since most other compressor problems are internal. It’s recommended that you follow Step 3 before having the compressor checked. The Toyota Camry uses R134a refrigerant as part of its cooling process.
What should the resistance be on a Camry compressor?
Connect an ohmmeter to the two terminals on the sensor. You should be getting a resistance of between 100 and 130 ohms at 68 degrees Fahrenheit. If the resistance is too far out of this range, then the sensor could be faulty. Figure 2. The compressor is below the large belt.
What kind of refrigerant does a Toyota Camry use?
It’s recommended that you follow Step 3 before having the compressor checked. The Toyota Camry uses R134a refrigerant as part of its cooling process. As the refrigerant heats and cools, it maintains a certain amount of pressure within the A/C system.
