You need to check the re=turn air filter and kmake sure that its clean/. Basically it shuts down the ignitor due to high outlet air temperature. Stay Warm!!!

Outside unit will only run for a short amount of time with A/C before the fan stops turning and starts humming, squealing/screeching and the top of the outside unit gets hot.


The bearings are bad in the motor and after the fan runs enough it eventually gets hot, making the bearing screech and the fan locks up. Need to replace motor again. See if it has a warranty. The reason it gets hot is because the fan is what removes the heat from the coil and if the fan isn't running there is nothing to cool it off so to speak.

My Aircon indoor unit will not run continually on cooling. It runs for short bursts then stops.


One thing that I am not seeing in your description is that the coil sensor has been replaced. I find it strange that a phone tech could diagnose this, send out a technician and not replace this component. Was the service tech an authorized LG repairman? That is where I would start. I would call LG and ask them for a certified technician supported by LG in your area. I feel you will have better luck with that approach.

Fujitsu inverter air cond. Just stopped working properly. Model outdoor AOT30PMAL indoor unit AST30PBA-W. Code oper. Red led flashes fast continously green led (timer) repeats 13 slow flashes. After power...


It sounds like your inverter is at fault. You will need an inverter tester ( most good service techs will have one ) to prove that the output to the compressor is correct. If the inverter is okay then it will be the compressor at fault with a location error or it is simply seized. A common fault that caused this was the eev remained closed (coil failure ) and caused the compressor to over heat.

Everstar portable ac unit displaying error message P1. The unit turned itself off and will not come back on. It had no symptoms of not working well before turning off.


According to my Everstar manual, P-1 is a drainage problem.
EverStar owners manual pg. 16 -

1. Release the drain hose from the ruber clip and pull out the rubber plug, let the drain hose slant down to a water container.

2. Press the TURBO button on the unit control panel for more than 3 seconds and the WATER INDICATOR light begins flashing. It indicates the forced water drainage feature is activated.

3. Waiting until the WATER INDICATOR light stops flashing and there is no water flow.

4. After the water has drained, remember to secure the drain hose and plug in the upright position and clip it to the unit.

The unit will return to normal operation.

....I had to do this and it worked - Good luck!

TOYO mini split air conditioner made in Japan is very very good quality and it can runs for 20 years without any problem. You didn't hire a best ac technician to install your TOYO unit. The tubing connection between indoor unit and outdoor unit is not the right torque and refrigerant leak. Your TOYO unit runs out of refrigerant. You need fix the leak and fully charge the system. You will solve the problem. Good luck!

Unit stops working - E1


I wrote the solution #1 and have an additional comment. This really does work!! I fixed my neighbor's AC unit by following the instructions for clearing the E1 code. The unit will not operate until the code is cleared. The page is titled: Customer assistance for air filters cleaning (E1 code) on Sharp Air Conditioners
