SOURCE: my indoor blower is not working it blinks 8 times

This alarm state is a CH08 alarm. Which indicates that the indoor unit fan motor has a locked rotor. Solution is to check the indoor fan capacitor and replace or test the windings of the indoor fan motor. Note: the indoor fan motor is a BLDC fan motor and can not be replaced with any other motor. It runs of a voltage regulated frequency.

FUJITSU Inverter wall mounted split air conditioner Model : AST12LSBCW not working, flashing lights


This is a "PFC circuit abnormal" in the outdoor unit meaning that the outdoor controller board is faulty. Try turning the machine off at the isolator switch for 10 mins, then back on to see if the error resets. If not you will need a new controller PCB.

I want 38424 to turn on a lamp at 8 PM and turn off at 10:05 PM - Do I set it on "Timer" or "ON"


You want to set the clock after charging the device. Takes a short time. Set the time by pressing TIME and then HOUR/MIN for the current time. Now you can set the timer.
Press the "ON" and set the time you want the device to turn on.
Press the OFF button and set the time to the time you want the device to turn off.
Put the switch on the top to the TIMER position and lug into the wall socket and then the device into the timer.
Should be good to go.

5 Low pressure/Overcurrent protect

6 Indoor-outdoor communication error

Misubishi split a c 2 tons green light blinking problems


Please write how many times blinking and with an interval. Depends upon it, we can give solution.

Normally, blinking 5 times means for drain motor malfunctioning. Check drainline, oif blocked clean it. If drain motor not working, replace it.
If blinking 2 times, Indoor room air thermistor defective replace.

Thanks.

My split unit air con will switch off automatically every 10 minutes and the lights will blink. It can only be turned on again if the power is switched off from the mains.


May be in indoor screen there is some error code. Don't worry. I try to solve it. Normally after 3 minutes compressor will start. If compressor amps gradually increase due to condenser block or less rpm of fan motor. Please ensure with amps meter for increasing ampere It will run just 10 minutes or up to the maximum running amps and get tripped. Service your indoor and out door and check. . Is it helpful?
