View Full Version : carrier compressor problems
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
-20

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...
