Hi.
AC compressor was leaking. Took it to repair shop.
When i went to get it i was suprised that they have removed 2 sensors on it and closed the holes.
They claimed that those sensors were too bad, are common point of the leak, and are unnecessary. To proof it, they told that new compressors for the same model cars do not have those sensors.
I made some research. There are total 3 sensor on the AC system.
One sensor on hose (low pressure sensor). If there is no freon, it breaks the circuit.
And 2 Sensors on the compressor. One is High pressure sensor (ON/OF sensor. it increases fan speed if there is high pressure) and the other is Ultra High Pressure sensor. Which breaks the circuit again in orter the save AC (or may be prevent freon leak through the valve)
Actually without those sensors AC can actually run. But without any protection. We can make Fan run at its maximum speed all the time at the cost of fan life.
I am planning to buy replacement Compressor. it is 70$. They will install it for free. But since it is summer, it is difficult to find one.
So i want to use this for a while.
The question is, Is there anything that i can do in order to reduce chance of high pressure ? What causes High Pressure in AC System ? Higher RPMs ? or when AC runs for a long period of time or Stop-&-Go Traffic ?
Regards.
