AC stuck on cold, compressor still hums after power off. Tried up and back down temp settings, tried ac reset switch, unplugged 15 min. It is still stuck on after I plug in again.

There are a couple of options. Disconnect the battery, then drive the vehicle around without using the AC for 10 min, if the AC is defaulted to come on after a battery interuption, then shut the car down then turn it on again. You are trying to get the electronic actuator to reset and resume proper function. Another option is to try this: Start the car, adjust the pax side full hot, drivers full cold, wait 30 sec then shut car down, then start car back up and reverse the settings, pax full cold, drivers full hot. In both solutions, the vent actuators are stuck at either the full open or full closed, so you are trying to get it to 'self check' and allow them to resume proper function. After two years, I simply removed them altogether since I live where it is hot an only need cold.works just fine....
make sure the cooler(s) are clean. Next check the airend discharge temperature switch commonly called a HAT (High Air Temp) switch. These switches will reset as the compressor cools down. I would be able to access the switch quickly. Run unit until shutdown remove wires and see if switch is open. if open you found your problem
I have had a similar problem. The A/C switch was wearing out--try turning your heater all the way up for about ten seconds and then all the way down. If it resets you will need to do this every time you turn the temp up and then want to go down.
To reset your AC compressor, you need to remove power for at least 15 minutes. After you reconnect, the compressor should turn on. If it does, immediately turn to high and try to add refrigerant. Best of luck.
GM products have a safety feature which shuts down compressors is they run too low on refrigerant. Honestly surprised you were able to fill the system with refrigerant since the compressor would have shut off. The best way to reset the compressor is to disconnect the negative battery cable for 15 min. After reconnecting, the compressor should function again assuming there's enough R-134A in it. If there's not, turn the AC to MAX and add the refrigerant. At this point, the system should actually **** the can dry. Hope this helps with your AC problem. All the best! Greg
See if your motor is okay 1st. Find your wires feeding your Fan motor. (This means the 2 power wires L1 & L2 if 220v or L1 & N if 115V) Carefully put the power to these 2 wires and see if you hear the motor hum or start. If it hums the run capacitor could be bad.Try spinning the motor with the power applied. If it starts most likely the run capacitor is out. If it starts without you helping it the control board or switch is most likely out.
It is possible the unit has a energy saving setting. If it gets locked into this the fan may not run. If the unit has electronic controls and an electronic display read out, the board is the most likely suspect. Unplug it and see if it resets. If not then the board is probably out with a stuck relay or stuck program. New board time. Or replace the unit.
If it has a rotary or push button type control then either of these 2 switches are suspect.
It is probably either the high pressure switch or the frost control. The high temp switch usually trips because the condenser coil is dirty which does not allow it to exhaust heat very well. The frost control will trip if the system gets below 39 degrees on the pipes. This is usually do to low refrigerant or dirty filters. Good Luck!
First things first. We'll start from the beginning. Unplug the AC Adapter from the wall and from the Wii. Let it sit for 15 minutes. Then plug it back in. 9 times out of 10 your power supply needs to be reset. The only way to reset it is to unplug it from the wall and the wii and let it sit for 15 min. Try this first and report back if it worked. Even if you think you have done this already do it again.
With the AC adapter and battery installed and it will not power up remove the adapter and the battery. Then plug in the AC adapter after both have been removed for 30 seconds and let the laptop set for 30 seconds and then unplug the AC adapter and then slide in the batter within 15 seconds and try to start the laptop.
