2. Disconnect power to the CAS unit and repeat Step 1. NOTE: The unit should not run and the appliance
should not  re in this condition.
3. Inspect the duct pipe for loose joints, damage, and security to the CAS unit and StarKap.
4. Clear any obstructions, if present, from the inlet of the StarKap and the outlet of the CAS unit.
5. Periodically, the fan blade chamber may need cleaning. First, disconnect the power supply to the CAS.
Next, disconnect the duct pipe from the unit. Then remove the top pan and clean the fan housing area as
