Hi,

I think the motor is OK, because the fan is working (non stop until I press the button to turn off). Probably are the valves.

Today I've observed that when I press the air re-cycling button, sometimes nothing happens and sometimes the airflow is greater. Do you think that the valves are involved in the air re-cycle circuit? Or, may be the air filter?

I think that the air filter is only for the external air, and when the air re-cyling button is pressed, the air doesn't pass for the air filter... isn't it?

Where are the valves and where are the air filter? Can I clean the valves and/or the air filter? Is it easy to do?

Thank you in advance and regards,
Jorge Ruano
