What Causes the Truck Air Conditioning Compressor to Fail to Start?
1 Answers
Truck air conditioning compressor fails to start due to prolonged operation under insufficient Freon levels or incomplete air evacuation during installation. Here are the related explanations: 1. Prolonged operation under insufficient Freon: Improper installation leads to system leaks, resulting in insufficient refrigerant. 2. Incomplete air evacuation during installation: Ice blockage may occur, increasing compressor load. The heightened compressor load raises its temperature, causing prolonged high temperatures to degrade the refrigeration oil. This degradation impairs lubrication and cooling functions, further elevating compressor temperature. The high temperature reduces the insulation of the coils, leading to compressor damage.
