What to do if my Whynter Portable air conditioner unit turns on but is not cooling?

  Mr. Jonathan WatsonAug 18, 2025
  If your Whynter portable air conditioner turns on but isn't cooling, consider these points: * Ensure the room temperature is within the unit's operational range (64°F to 95°F). * Press the MODE button until the COOL light appears on the display. * Allow the compressor 3 minutes to start after selecting Cooling mode. * Set the temperature lower, ideally at least 5°F below the ambient temperature. * If the internal water reservoir is full, manually drain it or allow the unit to exhaust the water in fan-only mode.

  taravelezSep 4, 2025
  If your Whynter portable air conditioner is making excessive noise, ensure it's placed on a hard, level, and stable surface. If the noise persists, try moving it to a location with a level and hard floor. Also, make sure the wall outlet can support the air conditioner's power consumption without using an extension cord.
