this is my first time writing in so bare with me. I have a RTHB 300 that i cant get to load up. After trying things from putting the unit into a manual load through the controls to appling discharge pressure at the schrader port next to the load and unload solenoids. The load solenoid does pulse but I can not get the thing to buckle down and do its duty. Even at 10 degrees above setpoint it only hovers at about 42% RLA. Suction press. and disc. press. are normal and it isnt a lack of refrigerant. The gentleman at Tech. in Pueblo tell me i should rebuild the piston assy. that moves the slide over the rotors. It seems very labor intensive since I have to remove the oil tank and separator to get to it.
Has anyone done this rebuild or have seen these symptoms? I have it scheduled in a couple of days. Was just hoping for some input....thanks
