My dur therm air conditioner fan turns on but compresor does not

When I first started it up the fan came on and then the compresor after turning the colder dial. The compresor shut off in about a minute and after a little while it came back on again but once again shut off. And has not come back on since. I have tried warming the sensor in the vent to get it to come on but still nothing. The dial is set to the coldest position. When the compresor did come on it was blowing cold air, I need it to blow cold air all the time and would just as soon bypass the sensor if this is the problem.

I got a new control box for my Duo therm travel trailer A c unit . when I removed the old unit and started to replace it with the new unit I found that the new unit came with a new thermostat which I replaced > The thermostat came with a detailed wiring digram and it was easy to install. When I started to wire the new box i discovered there is no wiring digram for the new control box. My question is where can I get a wiring digram that will help me to wire in the new box witout making a mistake and hurting the new unit?

It could be the (LP) low pressure switch which would shut the unit down

Fan running but dont hear comp. turning on


First check for burned wires in all the componnents in the condensing unit ,also the compresor terminals ,if they're all ok and if you know how and have a tester check the compresor if is not burned or grounded. After that you can replace the capacitor (is no more than $20) and if still won't start it means the compresor is either burned or stock.You can also try to put a start booster in parallel with the capacitor ,sometimes it helps it to start.

Turn the ac off go up top the coach and remove the cover. Look for fan blockage, Wasp, mud dauber etc. Caution if it is wasps they will chase you off the end of your coach. Take some spray with you. If there is no blockage the fan motor is toast.
