• What should I do if my Colku GCP15f air conditioner does not turn on?

  Make sure the power supply is connected correctly (100-120V) and try pressing the power switch again. Note that if you turn the unit on and off frequently, the compressor's auto-protection function may delay startup by about 1 minute.

• How often should I clean the air filters on the portable air conditioner?

  It is highly recommended to clean both the front and rear air filters every month to ensure efficient operation and maximum cooling performance.

• Why does the display on my Colku fridge show an E1 error code?

  An E1 code indicates low voltage. Try testing the fridge on a different power source (such as 240V AC). If that resolves the issue, check your vehicle's power source or ensure the cabling between the fridge and battery is at least 0.16 inches thick.

• What does the ED error code mean on the Colku air conditioner?

  The ED error codes means the unit is full of condensation. You should turn off the air conditioner, shut off the power, and open the drainage hole to properly drain off the water.

• Do I need an app to control my Colku car refrigerator?

  While not required, some Colku models support the 'Colku Car Refrigerator' app (available via WeChat mini-program or app store), which allows you to remotely turn the fridge on or off, adjust the temperature, checking battery protection levels, and switch cooling modes.
