Hi everyone

I'm new to this site but from what ive read so far it sounds like you guys know your stuff. Ive got a carrier reefer(69NT40-511-312) with a recipient compressor that stays in a vacuum and doesnt reach its set point, i think it mite be the txv that is faulty but any other advise would be greatly appreciated.

Set Point -20
Return temp -0.2
Supply Temp -16,7
SMV 100% Open

Thanks in advance

no air flow, so blocked evaporator coil or fan clutch not working so no drive to fan in back, try these first.
if you take off the evaporator panel you'll see a big ice formation

have you physically check the SMV may say100% but could be stuck closed

he has a very big temp difference across the coil, so i'm thinking simple stuff first

thanks for input guys, but after further investigation i found that the txv bulb was broken. replaced faulty part, reefer running fine now.

Anybody know where i can download th new 5#54 carrier software, the port i work at is not a registered carrier service centre so i cant get the software from carriers site?

I work with a compressor manufacturing company............... Anytime anything goes wrong other than with compressor , customers relate it to compressor faulty , not working ,defective etc . I thought it is a local phenomena but appears to be a common .

No guy, like i said the TXV was faulty. Nothing wrong with the compressor, i wasnt even hinting at that...
