Control Knob

Control components coordinate timing and outputs across the machine. When control logic fails, you can see no-start conditions, erratic cycling, or random shutdowns. Part 02-3858-01 corresponds to the Multiple brands Control Knob, used in service situations where wear or damage is disrupting operation. Depending on installation, failure can present as unexpected shutdowns, 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. Disconnect power before service. Reassemble so nothing pinches, rubs, or binds once the unit is back together. A correct-fit replacement helps restore predictable operation and reduces repeat service calls. 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.
