Rudd Air Conditioners

I have a Robertshaw thermostat, 300-266.
I put in setting fees, the snowflake is flashing and I have programmed.
I have replaced the filter today, still does not work.
Outside I have a Rudd fan heat / air conditioning Rudd. It has a reset button high pressure "and I pressed it tension, but soon after he leaves.
I rinse the unit with my pipe, still in vain. It does not look like there is ice or anything about it. He may have to do with the thermostat? I do not know ... HELP

Thank you in advance!

The unit stops due to a high pressure condition. This feature is designed to prevent damage to your air conditioning system. Since you have made practical checks that the owner can do and there are still problems, it is time to call a pro.

It is true that it can cause too high pressure Flag

Try re-setting the control panel by disconnecting the power to the thermostat

Try replacing the thermostat if it is ot as checking to see if the engine is running. I am the same problem.

Try taking your car off and the thermostat set to manual and adjust the temperature. where you want and see if it works.

maybe you are low on freon so, you must call for help
