1. Have 610015.405 AC Penguin model that has no low or medium speed and low voltage light comes on at these speeds only. Works fine on High. Suspect control board, is that right? Where do I get a control board. 2. Have another AC, same model, that comes on even with switch off. Is this switch or control board? What is going on? Parts? Thanks in advance for your help. Van
