What to do if my Fujitsu ASYA07LBCM Air Conditioner is leaking water?
If your Fujitsu Air Conditioner is leaking water, first check if the filter is clogged. Also, inspect the drain hose connection to see if it's loose, has a trap, or is clogged.
How to troubleshoot a Fujitsu Air Conditioner with communication error (Indoor unit Remote control)?
To troubleshoot a communication error with the indoor unit remote control of your Fujitsu Air Conditioner, check the terminal connections between the remote control and the indoor unit, ensuring there are no disconnections in the cable. If the voltage is DC12V, the Remote Control has failed and should be replaced, assuming the Controller PCB is normal. If the voltage is DC 0V, the Controller PCB has failed and should be replaced, after rechecking the Remote Control.
What to do if my Fujitsu ASYA07LBCM Air Conditioner is making abnormal noise?
If your Fujitsu Air Conditioner is producing abnormal noise, check for issues related to abnormal installation of either the indoor or outdoor unit and correct them. Inspect the fan for failures in both the indoor and outdoor units, looking for vibration noise caused by loose bolts or contact noise from the piping. Also, check the compressor for failures, referring to PARTS INFORMATION 1,2.
What to do if my Fujitsu Air Conditioner is not operating but the power is on?
If your Fujitsu Air Conditioner is not operating even though the power is on, check for any abnormal settings or connections, consulting the Installation manual and Data & Technical Manual for correction. Also, check for large electrical loads on the same circuit. If the problem persists after these checks, consider replacing the Inverter PCB of the Outdoor unit.
How to fix Fujitsu ASYA07LBCM Air Conditioner communication error (Serial Reverse Transfer Error)?
To fix a Serial Reverse Transfer Error in your Fujitsu Air Conditioner, first check for any loose or removed connection lines between the Indoor and Outdoor units, referring to the Installation Manual or Data & Technical Manual for correction if any abnormalities are found. If the connections are correct, reset the power and operate the unit. Also, check if the indicated value swings between AC70V and AC130V at Outdoor Unit Terminal 1 - 3. If it's abnormal, replace the Inverter PCB.
