GRILL-FRAME-CU26

If the machine is showing airflow restrictions, inspect this area for looseness, rubbing marks, mineral buildup, or secondary damage to nearby parts. After replacement, run at least one full cycle and recheck for leaks, vibration noise, and anything that loosens during operation. Diagnosing airflow restrictions can come down to one worn component—Grill Frame CU26 (part 02-4304-01) is a common replacement item. The listing name references model(s) CU26. Good fitment reduces vibration noise and helps keep debris and moisture away from sensitive areas. Use part number 02-4304-01 as the primary identifier, compare the replacement to the original, and install with careful alignment and routing. Replacing a worn part early can prevent secondary damage to nearby components. If the part interacts with water, do a leak check during the first run and again after a short operating period. Take a photo before disassembly so you can confirm orientation and fastener locations during reassembly. Recheck fasteners after a short run-in period; vibration can loosen hardware if it isn’t seated correctly. If the part interacts with water, do a leak check during the first run and again after a short operating period. If the part interacts with water, do a leak check during the first run and again after a short operating period. Clean the area around the repair so debris doesn’t interfere with fitment or sealing surfaces. Take a photo before disassembly so you can confirm orientation and fastener locations during reassembly. Recheck fasteners after a short run-in period; vibration can loosen hardware if it isn’t seated correctly. If the part interacts with water, do a leak check during the first run and again after a short operating period.
