HELP: Carrier 38EXP009 shutdown problem

[Kasamiko]

Hi,

This is my first post so please be gentle guys. :rolleyes:

I'm working with Carrier Model: 38EXP009 Room Air Conditioners (Split-type).

The unit is shutting down after 15 minutes. I have to unplug the power cord to power it on again.

Any help will be appreciated.
