Carrier 30RA turning stopping at night

[Putte]

Hi!

I have a Carrier 30RA 017. It uses a Pro-dialog Plus Control and operates in local on mode. Problem is that it stops sometimes during the night or at the weekend and when i come, there are no alarms but the unit is in local off mode. I turn it on to local on and it starts and works ok. It has worked for the last 3 weeks before it stopped this time.

Alarm history shows 9, 37, 46, 36, 30. I also noticed that the alarm lights appear to be blinking in some sort of sequence even when the unit is running.

any ideas?

Could you give me the complete model of the machine? codes you mention do not appear in the manual.

Most of those codes seem to indicate either sensors or external switches/faults causing a shut down.

Hello Brian Have the same problem with the same machine. Our machine usually stays in Remote. when the power goes out it reverts back to local off. hope it helps.
