This demonstration guide answers one field question about fins packed with grass that never dried. Measurements come before parts, and the notes are not a generic equipment FAQ.
Diagnose before replacing parts
Start with fin packing depth. That reading separates fins packed with grass that never dried from adjacent faults that share the same complaint.
If the measurement is out of spec, treat the blower housing path as the primary path. If it is in spec, do not replace the blower housing path just to complete a parts list.
Repair the failed system
The usual correction is the blower housing path, installed to the documented spec for this complaint.
A demonstration shop records the finding so the next technician is not repeating a guess about fins packed with grass that never dried.
Stop before you make it worse
Do not running without the housing to "let it cool". That shortcut hides the original measurement and creates a second failure.
If the machine still fails after the blower housing path is corrected, convert the visit to a broader diagnosis rather than stacking parts.
