The inside air space is warmer than the set temperature but air is flowing uniterupted, compressor is attempting to turn on but is hot, the temperature and the pressures may be the same.
Check the low and high pressure switches, the AC fuse, and relay. Any of these can cause the AC to not get power to the clutch as if the freon is too low.
how do you check freon on central ac and what should the guages read.
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 is added through the low side ac port. A gauge is recommended to check the Freon pressure, as too low or too high pressure can cause the ac not to work properly.
Check the Freon pressure first. The AC compressor will not turn on if the Freon pressure is too low.
The ac is recharged through the low side ac port. Using the right type of Freon and the proper gauge for that type of Freon, connect the Freon to the port and fill to the proper gauge reading. Check the can for exact refill directions.
Low or no freon will cause the AC not to work. Also if the clutch on the AC compressor has failed, or if the compressor itself failed.
You are low on freon or any of the other various chemicals needed to run the AC. Your pressures are low on this chemical.
low on freon
No
CHECK THE AC RELAY ALSO CHECK COMPRESSOR CLUTCH DIODE FOR SHORT. GOOD LUCK PAUL G
ding freon will make it colder, only if freon is low. if freon is low you have a freon leak so adding will be wasting time and money. more likely to need a new ac temp thermostat, which is no big deal to change
