My AC units will shut off before the temp reaches the set temp. I thought is was my thermostat so I replaced it. No change.
Example. Temp is reading 80. I set temp for 76. The AC goes on. The thermostat (LuxPro) has a blinking indicater when the unit is blowing. The AC stays on for a few minutes dropping the temp to 78. The unit then s off. The indicator on the thermostat still shows that the unit is on but it is clearly off. It stays off for a few minutes and then starts again. Eventually bring the temp down. I place the thermostat in the on position not Auto and the same thing happens. It happened with two different thermostats So I beleave it is the handler or compressor that is the probmem. Any suggestions would be greatly appreaciated.
