The return air filters are the heart of your Friedrich AC unit, and they require regular cleaning to maintain optimal airflow and efficiency. Gently remove the two return air filters and rinse them thoroughly under running water. Use a soft brush to remove any stubborn dirt or debris. Once the filters are clean, allow them to dry completely before reinstalling them in the unit.

Clean the Air Outlet Component

Next, focus your attention on the air outlet component. Open the air outlet component and lock it into place, ensuring that each component is easily removable and cleanable. Use a soft-bristled brush to gently remove any dust or debris that has accumulated on the surfaces.

Clean the Supply Air Outlet

To clean the supply air outlet, begin by removing the PCB box cover and loosening the step motor wire plug at the terminal. Remove the screws and carefully pull out the supply air outlet component. This entire assembly can then be removed for a thorough cleaning, using a soft cloth or brush to wipe away any dirt or debris.

Clean the Supply Air Fan and Blower Housing

The final step in cleaning your Friedrich AC indoor unit is to focus on the supply air fan and blower housing. Start by removing the PCB box cover and loosening the fan motor wire terminal. Remove the trim panel, then open the supply air outlet component and slide the locking slides into place to lock it in the open position. Remove the five screws, pull down the fan motor wire, loosen the drain pipe, and remove the base pan assembly. The fan and base pan assembly can then be cleaned separately, using a soft brush and mild detergent solution to remove any accumulated dirt or debris.
