My Mitsubishi split aircon stops after a couple of minutes, and green operation light flashes. I have checked filters and timer, both OK. Will turning it off at the main switch board reset things?

Called Flash Codes. First try turning off everything at the breaker for at least 2 hours and preferably overnight. Turn back on and wait 15 minutes for self test to complete.

Hi I have Mitsubishi split unit which is 5 years old. when turn heat mode for 30 deg C on the remote condesing unit runs for about 6 minuts and stops. what would be the Technical problem ?Thanks an Apprentice.

Did you try this yet

SYSTEM RESET
If the TV will not respond to either the remote control
or the front panel controls and/or will not power Off,
press the SYSTEM RESET button with a pointed item
like the end point of a paperclip. The TV will turn Off
and the TIMER light will flash quickly for about one
minute. When the TIMER light stops flashing, you may
turn on the TV again. Changes you made the last time
the TV was On before you used the SYSTEM RESET
button may be lost, however, the changes you made
previously are not lost.
POWER/TIMER Indicator
The green light is a multi-function indicator. This light
will flash rapidly for about one minute each time the TV
is plugged into the wall electrical outlet, when power
is restored after a power failure, or using the SYSTEM
RESET button. Do not attempt to turn on the TV again
during this period. Wait for the flashing to stop and
the light to turn off, before attempting to turn the TV
on. While the TV is powered on, the light illuminates
steadily. If the TV has been programmed to turn on
automatically using the Timer feature,

reset the unit by disconnecting the power supply for 10 sec. then "on" again and start the unit. If it wont work you need a qualified tech. to solve the problem.Some of your safety device might be defective.
