I recently purchased the Maestro fan control and LED+ dimmer switch. Installation was very easy and everything appeared to be working correctly until I tried having both the fan and light on at the same time. The fan and light switches both work perfectly when only using one and not the other. If I try to have the fan and light on at the same time, the light will turn off whenever the fan is on. Is there a way to correct this or is the switch defective?
