What Does an Air Conditioning Expansion Valve Do?
The expansion valve meters refrigerant into the evaporator of the cab air conditioning system. It drops the pressure of the liquid refrigerant so it can absorb heat and cool the cab air. A stuck or clogged valve leads to weak cooling or an icing evaporator.
Signs the Valve Needs Replacing
- Weak cooling: too little refrigerant reaches the evaporator.
- Frost on the valve or evaporator: a stuck valve lets pressure and temperature drop too far.
- Unstable air conditioning pressures: gauge readings that swing or stay abnormal.
These symptoms overlap with worn pumps, dirty oil and clogged filters, so check the basics and measure pressure before replacing the valve.
