SWITCH

Part-number match matters: 12-2391-01 corresponds to Switch for replacement service. Order by part number to avoid mismatches. Disconnect power before service and document the original routing or hardware positions with a quick photo. Reinstall carefully so nothing pinches, rubs, or binds once the unit is back together. A correct-fit part improves reliability and prevents small issues from becoming bigger failures. Switches provide on/off or position feedback used by controls and safety logic. Intermittent switch behavior can look like larger electrical problems. Technicians may encounter unit not responding, no power, or intermittent behavior depending on the application. Compare the old part to the replacement, paying attention to connector orientation, mounting points, and sealing surfaces. Check nearby components for secondary damage so the new part isn’t stressed immediately after installation. Replacing Switch can resolve unit not responding when the fault is confirmed at this component. 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.
