I have a camper with a Carrier Air V AC system with the wireless

Customer Question

I have a camper with a Carrier Air V AC system with the wireless remote control thermostat. Last year the system quit. The interior portion in the ceiling will still run the fan, but if I turned it to COOL, it would shut off and blink 5 times.
I had an HVAC guy tell me that the rooftop model had leaked all the freon out.
So I just purchased a Dometic Brisk Air model 459516, and also the conversion kit model(NNN) NNN-NNNN000. It converts Carrier to Brisk Air.
I installed this on Sunday, very easy to do. Everything fit perfect and plugged right up.
Now I am still having the same issue. Air will come on, blow (NOT COLD) air, and shut off after 5 minutes. Then after a few more minutes, it will do the same thing again.
Is there some issue with the wireless remote, or did I miss something? It all seemed like a very easy process to do.

Hi: Thank you for coming to Just Answer with your question. My name is Randall and perhaps I can assist you with this issue.I hope you didn't throw the old Carrier unit out. Those are the most reliable A/Cs ever made in my view. I suspect that you HVAC guy didn't know what was wrong and just guessed at this. You need to start by confirming the AC voltage TO the A/C. If it is below 110 VAC then check the voltage OUT of the service breaker. This sounds like a bad breaker or some other voltage issue. When the voltage drops the amperage goes up and so does the temp in the wire and trips out the breaker or some other protection device. Let me know what you find. This will require a small digital multimeter like you can find at most automotive or hardware stores for about $15 or so. All follow ups are included in our fee. No limit as to time or number of responses needed.
