SO you are saying the furnace fan comes ON and blows cold air and when you run the AC unit it does not cool?

COULD THIS BE A FUSE ISSUE?
RV Mechanic: Robert, RV Mechanic replied 3 months ago

I doubt this is going to be a fuse issue, if that was the case then nothing at all would happen for the furnace OR AC unit.

So have to troubleshoot these separate.

RV Mechanic: Robert, RV Mechanic replied 3 months ago

IF you want me to try and help you with troubleshooting I can, I need the make and model of the furnace and it is really important to know if it is sparking, after the fan comes up to speed you should hear the electrode in the furnace spark and click from the gas valve. AS the blower motor comes up to speed it closes a sail switch, only they will you get spark, if you had low DC voltage the fan can slow down and you would never get spark, so make sure your battery voltage is above 12.5 volts or the fan can start to slow down, that would apply if you are not getting any spark.

For the roof AC not blowing cold air you should hear the compressor cycling on and off, if that is not happening check the breakers in your breaker panel and make sure the breaker is not tripped for the AC unit, it needs both AC and DC power to work...

I see you requested a phone call, it did not go through, there is an ADDED fee for a phone service.
