What to do if Royal Sovereign ARP-1400BLS Air Conditioner runs but does not cool?
- SSteven RiceJul 30, 2025
If your Royal Sovereign Air Conditioner runs but isn't cooling, check for open doors or windows and close them. Ensure there are no other heat-emitting appliances in the room; if there are, turn them off. Inspect the air filter and clean it if it's dirty. Also, check for any blockages in the air exhaust or intake. Make sure that the set temperature is not too high, and reduce it if necessary.
