Insulation - Part obsolete, USE 02-3663-20

Depending on installation, failure can present as misalignment, intermittent operation, abnormal noise, or a cycle that won’t complete normally. After replacement, run at least one full cycle and recheck for leaks, vibration noise, and fasteners that loosen during operation. Use part 02-3810-20 when ordering the Multiple brands Insulation for repair and maintenance. The listing indicates this part is superseded by 02-3663-20. Brackets, clamps, insulation, and fasteners keep assemblies aligned under vibration. Loose mounting leads to noise and repeat failures. Match the part number 02-3810-20 to the old component before ordering, then reinstall with careful alignment and routing. Once the root cause is corrected, performance should stabilize and output should return to normal. If the part interacts with water, do a leak check during the first run and again after a short operating period.
