The air con responds only sometimes to the remote request to turn on Its brand new MSZ-GA71VA

Lift the front cover of the air con, on the right hand side there is a button or a hole which has a button inside which you can press which is for manual starting of the air con. If this works, then you will know the remote is faulty, if it still doesn't work, check that the isolator switch for the air con hasn't been turned off. There will be 9Or should be) a switch outside next to the air con outdoor unit to switch power on / off to the air con. If not, there should be switch inside the meter box at the front of the house. Make sure they are switched on.

Start by replacing the batteries to your remote control and make sure there is nothing blocking the IR receiver on the unit itself. If that is blocked by something hanging on it or tape over it from something hanging on it previously.

pull up the front cover the grill looking piece , not the air out louvers , there maybe a little button , push that in if air con starts up , then you remote sensor may be faulty or the remote itself .

Wait 5 mins after turning the unit on to make sure it is not on a pre heat, and if problem is still there check fault code on controller

It's clearly understood that your receiving sensor not supporting with the remote. You have to repair PCB receiving sensor.

Check for timer setting you have done. If it is, reset the power to unit and also remove battery in remote and reset it. If still problem write again plz.

dear sir/madam

please check when you make on your air con it,s getting turn off from it,s circuit breaker then it,s an electrical short circuit problem if it,s turn off by it,s remote controller then it can be micro control program error.
if you know how to read to a electrical meter then try to check your electrical main source it,s passing electricity to air con and try to find out the problem
if not then try to contact to maintenance personnel. it,s up to you what you want to select option.

More than likely it is the remote sensor in the indoor unit. Then again I presume that it is the correct remote control. Sometimes a remote for one aircon may not communicate with another aircon even if they are the same brand.

I have discovered that a 7 day timer is available, but it is a fixed and separate box and will need to be programmed into the wall unit, at a cost of $500.As i am a pensioner and unable to afford this cost, I must persevere with the remote I have. Why can't the so-called experts provide a top of the line product in the first place?The last aircon unit I had was a Fujitsu, and that DID Have a very good remote enabling a programme of ON - OFF, On - Off in a 24 hour period. Thanks for trying to help.
