Switch is a practical swap when addressing unit not responding; order by part number 12-2886-01. Order by part number to avoid mismatches. Continuity checks and actuator inspection help confirm a bad switch. Switches provide on/off or position feedback used by controls and safety logic. Technicians may encounter unit not responding, no power, or intermittent behavior depending on the application. Reinstall carefully so nothing pinches, rubs, or binds once the unit is back together. After replacement, run a short test cycle and watch for leaks, vibration noise, or recurring faults. Using the correct replacement part helps restore steady operation and reduces repeat service calls. Compare the old part to the replacement, paying attention to connector orientation, mounting points, and sealing surfaces.

Once the underlying cause is addressed, input not detected complaints usually reduce or disappear. Verify any model compatibility notes shown on the product page before completing the order. Keep the removed part until final testing is complete so you can compare fitment if needed. If the machine was down for a while, take the opportunity to clean the area around the repair.
