Carrier A/C in RV won't run

Fan will run in fan only mode...but when you turn it to cool it will kick off. the green light is blinking 5 times. and there is a red light flashing... it was cooling great and then it seemed not to be cooling very well. turned unit off and let set a few hrs. turned back on and was not cooling turned off and cleaned filters(they were not really dirty) replaced them and turned unit back on and it ran about 5 to 10 minutes and shut off and will not come back on.

MY RV Carrier AC has a blink 5 pause then blinks 5 again. Unpluged circuirt board and the fan and compressor will come on for a minute or so and the nothing no fan no compressor. The fan mode works


Well I'm not sure what model unit you have but I found a manual online for the AirV series that has a 5 flash code. States that to be a compressor drive issue. If yours is an AirV series, call a technician. No help in the manual.

I have a Carrier RV Air V air conditioner. I turn


Have fan start capacitor checked/replaced by licensed tech, or electrician as they are very dangerous to work with if not experienced and can give a very high voltage shock, that could be fatal. They basically store and increase voltage to higher range for start up of fan and compressor.

Compressor appears to kick in, runs for short time


It sounds like your unit may have a bad run capacitor or start capacitor and relay. Low voltage will also cause this problem. First you need to make sure that you have the full rated voltages at the unit, if you do, then, have the run and start capacitors checked out and the start relay.

Compressor not kicking on


What type of thermostat are you using? When was the last time it worked ? Do you just get fan on cool mode, or does fan only run on fan mode?
