Intake vs filter size
Posted: Sat Oct 17, 2015 1:38 pm
After 5 short years, my blower motor died on my Goodman unit (ADPF304216). While the repair guy was here he made a comment that every downflow unit has repeated blower motor failures. (The installation and subsequent repair were done by separate companies.)
If I use a higher grade and pleated filter (20 x 25) the suction of the intake draws the center of the filter down a couple inches. If I use one of those blue fiberglass cheapies, it seems the unit strains less to move air. And somehow.....that triggered an old foggy memory.
The original unit had an A frame filter housing - setting directly over the A frame coils. Two filters were used - one on each side of the A frame. The unit I now have does have the A frame coils - but they taped a single filter housing to the top of the cabinet. Now I am wondering if the motor burnouts are caused by the reduced intake area of a single filter configuration.
Any thoughts?
