Anyone got any idea why this trane chiller’s compressor is not ramping up on demand, compressor initially ramps up but then ramps down even though the demand is there... I’ve recovered 43 .7 kg of r134a systems charge is 45 kg, removed expansion valve and tested expansion valve is good... strainer and sensors are good
