What to do if my Honeywell MM runs but is not cooling?
- J
  James BellJul 28, 2025
  If your Honeywell Air Conditioner is running but not cooling, several factors could be the cause. First, ensure all doors and windows are closed. Check and clean the dust filter, and make sure the exhaust hose is correctly reinstalled. Reduce the temperature setting on the control panel. Also, verify that neither the air outlet nor the intake is blocked. If the room is too large, move the unit to a smaller room, and cover windows with curtains or blinds to improve cooling effectiveness.

  If your Honeywell Air Conditioner isn't starting, begin by checking for power. Ensure the power cord is properly plugged in; remove and reconnect it.

Why does my Honeywell MM run for only a short time?
- A
  Amanda WatsonAug 6, 2025
  Your Honeywell Air Conditioner might run for only a short while if the thermostat temperature setting is too close to the room temperature; try lowering the set temperature. Also, ensure that the air outlet isn't blocked and that the exhaust hose is properly connected, without tight bends, as per the instructions.

Why does my Honeywell MM Air Conditioner heater keep switching off in Heat Mode?
- A
  Alexander FletcherAug 11, 2025
  In Heat Mode, the Honeywell Air Conditioner might switch off frequently if the room is too humid, causing the water tank to fill quickly. It's best to use heat mode in rooms with 50% humidity or less. Avoid extra moisture by switching off humidifiers or kettles.

  Mark ProctorAug 16, 2025
  If the heater in your Honeywell Air Conditioner isn't switching on, first check that the Heating function has been activated. Also, note that heating is activated only when the ambient temperature is below 25°C (77°F). Switch on the Heating function when the ambient temperature reaches below this level.

  If your Honeywell Air Conditioner won't run and the power button is blinking, it indicates excess water condensation inside the tank. You need to drain the water, referring to the Water Condensation Drainage section for instructions.
