What to do if my Daikin Air Conditioner indoor unit stops in heat pump mode?

  William HillAug 15, 2025
  If your Daikin heat pump model indoor unit stops or doesn't operate when the heat pump model is selected, it may be due to the unit being in cooling, dry, or fan operation mode, which will cause it to stop if the heating mode is selected. If the unit is not in operation and the Run button is pressed while in heating mode, the unit will not start. Check the specifications of the outdoor unit. If it is a cooling-only model, set the remote controller for a cooling-only model using the cooling-only/heat pump switch.

  Gerald LarsenAug 26, 2025
  If your Daikin Air Conditioner operation stops suddenly and the OPERATION lamp is flashing, first ensure the air filters are clean and that nothing is blocking the air inlet or outlet of either the indoor or outdoor units. Clean the filters or remove any obstructions, then turn the breaker OFF and back ON. Try operating the air conditioner with the remote controller again. If the lamp continues to flash, it is recommended to contact the shop where you purchased the air conditioner. Also, if you are using a multi-system, ensure all indoor units connected to the outdoor units are set to the same operation mode.
