Residential Carpet Extraction Equipment Maintenance & Repair

CLN 101 is a 10-lesson vendor-neutral course for technicians who service upright and portable residential carpet extractors. Learners trace the water and air paths, diagnose and repair pumps, check valves, trigger solenoids, spray bars, recovery floats, vacuum motors, belt and turbine brush drives, in-line heaters, switches and wiring, isolate leaks and suction loss, and finish with preventive maintenance and a bench quality check. Always unplug the machine and follow the manufacturer service documentation.
