    hi, Thanks for your reply,



    I've cleaned all the filters and made sure the outdoor unit is ok, but the error message wont go away, and the fan coil unit in the ceiling space won't turn on.

    Wondering if there anything which needs to de activated in the outdoor unit or some thing that needs to be reset on the keypad?

In cooling operation

When the problem occurs during a cooling operation, it is caused by an abnormal increase of the refrigerant gas pressure caused by a defective heat exchanger (faulty heat dissipation) in the outdoor unit during cooling operation. Check to make sure the rear and front sides of the outdoor unit are not blocked by any objects. If the heat exchanger (fins) located on the back of the outdoor unit is dirty or clogged, it must be cleaned. As a temporary measure, pour a small amount of water on the heat exchanger (fins). This may enable temporary operation of the air conditioner.

(Caution) The amount of water to be poured should be about the same as water that comes out of a sprinkling can. If a large amount of water is sprayed under pressure onto the heat exchanger, water splashes on or enters the fan motor and electronic parts, and it can cause other problems such as insulation failure and the activation of the circuit breaker

In heating operation
When the problem occurs during a heating operation, the problem generated in the outdoor unit during summer has manifested in the indoor unit. This problem is often caused by dirty air filters. Clean the air filters. If the problem resumes after the air filters are cleaned, the heat exchanger may need cleaning. Have the inside of the air conditioner cleaned professionally.

This occurs when refrigerant pressure increases which may be caused by irregularities in the heat exchanger or the condenser.
You need to check for the following/:

  • Check for clog or anything that may block the fins of the outdoor unit.
  • Check for dirt on the fins on the outdoor unit and have it cleaned.
  • Have the filter checked.
If the above did not work, you may have to have the AC cleaned out inside out by a professional. If you plan on doing this your self you may want to use high water pressure to clean the insides. If still that does not work you the heat exchanger may be defective and would have to be replaced.

Outdoor Activation of high pressure switch.

Disconnect the lead from the compressor and try and run the system without the compressor.
If it works OK or flag up a different code then reconnect the compressor (after you killed the power) and try to run it again, this time measure the voltage on the terminals of the compressor as it tries to start (Note: Use a good quality meeter, otherwise there is a risk of false readings, see other treads on this matter).

If the voltage by the compressor drop when the compressor is starting then you are looking for a poor connection somewhere.

My dakin ducted air conditioner only makes a humming sound when turned on. It shows error code E3 when i press the test button


That means
"Outdoor Activation of high pressure switch"
so it seems you may need a service tech. Ring Daikin Service locally and ask them whether this code is a simple adjustment or a service call.

Check out door fan motor is working. If not replace capacitor or motor.
Check compressor-gradually amps increasing-replace capacitor.
Check for gas pressure. No gas also gives over heat compressor.- Leak test and rectify.

Hi I have just got dimplex air conditioner gdc14rcssa it goes well for a while then come up with a error message E3 not sure why.


E3 Outdoor activation of high pressure switch due to over charged gas. and also due to less rpm of outdoor fan motor. High pressure due to non condensable gas. Remove all gas and flush out. Then vacumize and gas charge. If motor less rpm, replace capacitor or fan motor.
