Hello. My name is ***** ***** I'll do my best to help. Let's get started and see what we can do.
1.I always recommend trying a different set of batteries as even though new, they could be weak.
2.Was remote working before you replaced batteries?
3.Does unit come on when you try manual without remote?
Customer: replied 2 years ago.
Remote worked before batteries died. All the information shows up on the screen.
I can manually turn on unit without remote.
Expert:  airheatman replied 2 years ago.
Did you try a reset using the button inside unit? And did you try a different set of batteries?
Customer: replied 2 years ago.
Tried new batteries.
I will look for the reset button on the wall unit. Do I need to remove anything?
Expert:  airheatman replied 2 years ago.
I believe all you have to do is open panel. It should say OFF/ON Filter rest. Resetting should reset the unit itself.
Customer: replied 2 years ago.
No luck. I see only one button. I pressed it and remote doesn't operate unit. Attached are pictures.
Expert:  airheatman replied 2 years ago.
That is really strange. These are the only things I would suspect.Could be the receiver gone bad in unit, but I do not see how replacing batteries would have any affect on it.I am going to open to other experts to see if they have any ideas.
I have opted out of the question to see if perhaps other experts may have more information and can assist.Please do not rate or reply as that will send question back to my desk.Please stand by to see if another expert can assist further.
If no one can help. you can request a refund.
