I'll tell you what worked with my Fujitsu HFI system. I paid for 2 visits and it still blew air at 96'F.

Turn off the breaker and leave it off overnight. The removes all residual power from the circuit boards and does a system reset. If you go outside straight after your return power, you will hear random clicks and buzzes. Wait 10 minutes and then fire it up.

Also make sure the filters are clean.

This seems to indicate you have an RV though? This might help.

Well without a model number, I can tell you this. On some models, F3 indicates fan speed 3, which is high speed.If you push the mode button, these units will switch between f1, f2, f3 and smart fan. No problem.
On others, F3 indicates a fan speed error, either something is keeping the fan from turning, or there is a bad or loose connection somewhere.
On still other models, F3 indicates a freon leak or problem in the refrigerant circuit.
If carrier made their own units, they would probably act the same, but they don't. Model number is important, since the unit could be a daikin, LG or Samsung under the skin...

FF code means blown or missing damper fuse. Replace damper fuse (inside equipment cover plate) and try again. If damper fuse blows again, find and fix the problem causing the fuse to blow.

-When a blinking light problem occurs, your air conditioning system often shuts off too, meaning warm air is blown. You can switch off the circuit breaker of your AC unit, wait for a few seconds, and then switch it on again. For some, the unit will start working normally again.
