Error E3 Chigo unit

[sargiante]

Hi all,
I have a Chigo Air conditioner. It is a 12000 btu.
The model is KFR-32GW/EX1C.

One week ago appears on internal display unit a message: E3. I try to found it on user manual, but there isn't!

On web site (search on google chigogroup)
there is a pdf with Trouble Code but the link is broken! Murphy's Law?!

I try again on google and the only information about error E3 is:

E3 is not an error code, it means your system is simply defrosting itself and will resume to normal
operation in a few minutes time. This is a standard feature and should be left to complete the
defrost, no action is necessary.
In wintertime you may notice steam rising from the outdoor unit during defrost, this is normal. It is
also common for the outdoor unit to drip water in the winter; this is the moisture condensing on the
cold copper coils.
Please contact us if you have any doubts about the correct operation of your system.

For me there is a problem because defrosting don't star, and with 20° C external temperature... why defrosting?!

Any idea?
Thank you
sorry for bad english ;)

E3 coil temp sensor fault

1、Check whether the resistance of the sensor is normal
(the resistance is 5КΩ in the normal temperature
25℃), when it is abnormal the sensor should be
replaced.
2、Check whether there is short circuit or open circuit in
the wire of the sensor, and whether the plug is
connected well, whether there is welding off or
rosin joint on the electric control board, if there is
any, it should be repaired.
3、When the 1 and 2 are both normal, then the
components or integrated circuit is damaged, the
electric control board should be replaced
