What you can safely check
Fit fresh batteries with correct polarity and make sure the signal path is clear. Follow the model manual for settings.
What might need a technician?
The issue may be the remote, a setting or the receiver in the AC. Confirm compatibility before buying a replacement.
Do not open electrical compartments, bypass safety devices, handle refrigerant or climb to reach the outdoor unit. If there is smoke, a burning smell or electrical danger, stop using the AC and keep clear.
