Check
1.A - Frost only at the bottom of the heat
exchanger: gas leak.
1.B - Frost covers the entire heat ex-
changer: the air filter is clogged.
The room temperature is low
(< 20°C).
2.A - If the Internal Unit heat exchanger
remains dry and the electricity con-
sumption is much lower than the
rated value, then there is a leak.
3.A - The External Unit heat exchanger
is clogged or covered: you do not
have a good heat exchange.
3.B - The flaps on the External Unit heat
exchanger are bent.
4.A - The Internal Unit filter is clogged.
4.B - The air recirculates in the Internal
Unit.
4.C - The machine has not been sized
correctly or is overloaded e.g.: heat
sources, overcrowding,...).
5.A - The compressor is very hot: heat
protection.
6.A - The internal unit fan is broken.
