Rooftop rv air conditioner doesn't work - what can
I'm assuming when you say 'doesn't work' you mean 'nothing comes on,' i.e. the fan or the compressor.
If that's the case I would check for the AC breaker to see if it's tripped. Usually a 'tripped' breaker will look half on and half off, but sometimes it will be completely in the off positiion. Either way - it's usually because of a malfunction of the AC unit, so if that's the problem I would moniter it closely to see if it trips again. If it trips again in the immediate future I would then want to investigate the AC unit for the cause.
Also, some RV's have fuses in the AC circuit - so you could check and see if you have any fuses labled AC or AC control voltage. If so - you can usually - tell by looking whether they are bad or not. If that's not possible try replacing your 'AC labled fuse' with a new one of the same size.
I would also check your power supply (where the power cord to your RV plugs into) to make sure it is providing the proper voltage to your RV. Note: They also have breakers out on the box that you can reset. If they (breakers) appear ok - and you are at a RV park you could have the Park personel - check and to be sure the proper voltage is availible to your RV.

Compressor turns on and runs for about 1 min then
First replaced the thermostat then check on condenser unit that's outside .make sure the fan is running when compressor runs .if not there is your issue .If fan runs and compressor keep shutting off you might have a dirty coil so clean it out with water or you might have a leak in the system causing unit to shut off on low pressure .if this is the case you need to call a service technician .
Try simple things first like clean coil ,capicator and fan operation.

Duro Therm air conditioner
Most likley this is caused by a pressure switch dropping out then making again after the pressure drops off. Try cleaning your coil on the outside on the roof as most likley it is a high pressure switch causing this problem.

How do i wire analog thermostat to digital
You need to get a different thermostat.you can change an analog thermostat to digital, but you have to replace the motherboard with a digital compliant one. You can't just change the thermostat. Your best bet is to put back the old thermostat or upgrade to a different compatable thermostat
