Poor cooling or heating can occur if the air filter is clogged. Check the air filter. Also, make sure that there are no obstacles blocking the air inlet and outlet grill. Direct daylight coming into the room or too many people in the room can also be the cause. If the swing louver is horizontal during heating, adjust it.
What to do if my Mitsubishi Heavy Industries FDT cannot start immediately after stopping?
If your air conditioning system doesn't restart immediately after being turned off, it's likely that a circuit protecting the compressor has been activated. Wait for 3 minutes before trying to operate the unit again.

How to fix the Mitsubishi Heavy Industries FDT when it displays "(PREPARATION OF HEATING)"?
When "(PREPARATION OF HEATING)" is displayed on your Mitsubishi Heavy Industries Air Conditioner, this indicates that the unit is preventing cool air from blowing out. Please wait for a while; the operation will automatically switch to the normal heating operation. Also, after defrosting is complete, the operation automatically switches back to the normal operation.
