Arrived to no cool due to a failed 45/5 capacitor. Replaced capacitor under warranty and performed function check. During function check the technician noticed very high pressures on the suction line and low superheat. Normal pressures on the liquid line and normal subcooling. Found that the TXV bulb was very loose on the line. Secured the bulb and continued with function check. No improvement. TXV needs to be replaced under P&L warranty. Part needs to be ordered.
