Freon can leak. Since it will do so in the form of an invisible, odorless gas, it is very difficult to observe such a leak.
You are low on freon or any of the other various chemicals needed to run the AC. Your pressures are low on this chemical.
It is possible low on freon.
Low pressure relay is bad! Check freon pressure, if it falls too low, the compressor will not run (installed for safet of compressor)
Low pressure switch shutting the unit on and off. Possibly low on freon.
Yes, some of the low end brands are made without a low pressure safety switch and will allow the unit to run until the compressor dies, should the charge leak out.
Look to see if the compressor is running when the ac is on. If not, then check the Freon pressure, as the compressor won't run if the Freon is low.
Freon may need to be added when the ac is not blowing cold enough. A Freon gauge can tell you for sure if the pressure is low.
No. An AC unit is a closed system. It is braised closed with high temperature welds. If it gets low on freon, there is a leak. Running your unit can burn up your compressor.
Either the thermostat is not set correctly or is ultra sensitive; or the unit is low on freon.
Your a/c is recharged through the low side service port with with the blue cap.
yes
That would be my guess. Take it to a professional.
