Anyone else had this problem. I thought I had read at least one similar problem but cannot find it now.
1. The AC unit scenarios
a. After it has run a while at a given setting, it will no longer cool. I notice during weekends and mornings after it has been set at given setting for a long period the following will start to occur.
i. The air handler will come on for about 15 seconds then shut off. About a minute later, the air handler will come on again for about 15 seconds and then shut off. This process will repeat until I physically go over and change the thermostat setting.
1. I can lower it one degree and it will then run for 15 or 20 minutes with the compressor and air handler as it should and cool down the unit
2. I can lower it 1 degree and immediately raise it back 1 degree and it will then run for 15 – 20 minutes as it should with the compressor and air handler cooling the unit.
3. One time, I raised it 1 degree and it also came on and ran for 15 – 20 minutes and cooled down the unit as it should.
ii. As of 07/23/2014 – I can bump the thermostat, the unit will cool as it should and then only the air handler will come on for its 10 – 15 seconds until I bump the thermostat again. I woke up at 1 AM, 2 AM, 3 AM, and 4 AM Thursday morning hot, listened to the air handler push air 2 or 3 times and then got up and moved the thermostat to cool it down again. After I got up to go to work, this scenario repeated itself until I left at which time I just turned the unit off completely.
I have worked with the dealer and PT but no resolution yet.
