    I have a fedders ductlesssplit air wall mounted air conditioner which runs for a bit, then it cuts off showing an E5 error and that is only sometimes. When it does run constantly it does not cool the room. I cleaned the filters and still not cooling properly. I am curious to know what E5 is. It does not show anything in the manual

I managed to find the people who supplied the unit, it was still under warranty, and they said it was the thermistors (temprature probes, they replaced both of them) It is now working perfectly!

I just paid someone to diagnose mine which is doing the same thing. E3 on the Mitsubishi air con can mean a few things. 1. Unit is overcharging.
2.Faulty accurators
3.Electronic module.

Now this is all gobbledy gook to me but perhaps you might know more or know someone who does. I now have to pay this technition $75 hr until he fixes it.

I turn on the unit and run with no cool air after 3 to 4 mins the unit shut down the fan go off and I get a constant flashing
Do a visual check on the air filter, inside coil for freezing and the outside unit for obstruction of air flow. Check your owners manual to decode the flashing light. Good luck!

Fault E3 Have same problem, fan works fine but will not turn on cold air. Display shows "e3". I have a remote, but do not see a button "c".
Try this : Start the unit using the remote control, after that push the C button of remote control if C display at the unit then off the unit and plug out the power supply. Then plug in again and "on" the unit using the remote control.

The e3 light is on and its not cooling just fanning
The E3 error code, indicates that the water in the collection tank is full and needs to be emptied.
Turn the unit OFF & unplug it, before attempting to drain the tank. Once that is completed, the unit should operate as designed.

I have a samsung air conditioner - model AQV24NS and after 10- 15 mins it shuts down both red & green lights start flashing. The only wayi can get it to work again is to shut off the main power suply...
Please check outdoor unit. Compressor or fan motor getting high amps due to overheat. Clean condenser coil. If still problem, replace running capacitor. If out door fan less rpm replace fan capacitor. In some unit 2 in 1 capacitor is there. So replace one capacitor will rectify fan and compressor problem. Thanks. Helpful?

Either your fan is stuck due to age or grime or is shot

if the fan does not provide cooling then the unit goes into thermal protection mode and shuts down

TOYO TA-09CHS aircon problem
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.
