KNOB

Symptoms can present as noise, intermittent operation, abnormal noise, or a cycle that won’t complete normally—depending on where this part sits in the system. If the fault changes with vibration or after moving panels, look for borderline fitment, loose connectors, or wear marks around the installation area. If you’re sourcing Knob, ordering by part number 03-1675-03 helps you match the correct listing. This replacement component supports normal operation by restoring fit, sealing, alignment, or control behavior. Disconnect power before service. Reinstall so nothing pinches, rubs, or binds once the unit is back together. 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. Recheck fasteners after a short run-in period; vibration can loosen hardware if it isn’t seated correctly. 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.
