Why is my Matsui MPA7KWR Air Conditioner running but not cooling?
- RRichard BowersAug 6, 2025
Your Matsui Air Conditioner might run but not cool due to several reasons. Check if any doors or windows are open, if other heating appliances are in use, if the air filter is dirty (if so, please clean it), or if there's a blockage in the air outlet or intake. Also, ensure the set temperature isn't too high.
