AC Not cooling

I have a similar problem. My AC is running but it's not cooling down. When I got up this morning it was cooling fine. The temp was at 70 but as the day has progressed the temperature has progressively gone up and is now 78. This has never happened before and has been very sudden. Air is blowing but it's not cold. Any ideas??

Won't crank when warm


It is possible that the solenoid on the starter binds when the starter is hot. When you say that the starter was tested, was it tested hot?

Does the starter click when you attempt to start it? When you turn the key, the switch energises a small relay, which in turn energises the solenoid, which in turn applies power to the starter motor.
The solenoid should make an audible sound when it pulls in the plunger.

If you have a second person, one could turn the key, and another could gently hit the solenoid with a rubber or plastic hammer. This worked on a Dodge minivan that I had.

An image of the plunger is available at

Does the fan always run


Cooling fans only run when the temp,of the coolant get to about 215 to 218 degrees,and shut them selves off,when the engine cools down,if they do not cut off,the engine is not cooling down,now,if the ac is on,the cooling fans will stay on until the ac is shut off.

Our de-humidifier is running cool but there is no water in the bucket, should there be?


Is it warm outside,and do you have your A.C. on? Dehumidifiers ,just like A.C. systems, remove humidity. If the weather is cold, put an open gallon of water in front of your unit and let it run a day or so. If the bucket gets water in it, and the container of water goes down, then the unit is working.

RV AC unit won't cool, blows chuncks of ice


It's most likely an airflow problem, you say you had the vents closed? Icing up is normally caused by lack of load (air flow) or loss of refrigerant charge. Make sure all your vents are open to allow for as much airflow as possible and that your filter is clean. Some units do not work well on low airflow setting when the outdoor temps cool down at night.

check the condenser fan is working properly and have the gas pressures checked by gauges

You have lost some charge in your system. I would have a mechanic top off the charge but also add some refrigerant oil as well. The cool will often slow down at an idle, but should not start to blow warm.
