Why is my Perfect Aire PAHP18002 not cooling the room?

Several factors can cause this. Make sure the unit's size is appropriate for the room, and all doors, windows, and openings are closed. Ensure nothing obstructs the front grille. Allow sufficient cooling time, especially in high outside temperatures. Check that the filter is clean, louvers are open, and the unit is in Cool Mode with an adequate temperature setting. If near a heat source, relocate the unit. If the air is cool to the touch, double-check the above points. For the 'Follow Me' remote feature, move the remote away from the unit. If the temperature sensor behind the air filter is touching the cold coil, carefully straighten the tube away from the coil. As a last resort, unplug the unit for at least 5 minutes and follow the reset instructions on the plug.
