The technician arrived at the dry cleaning business at the scheduled time of 8am to perform routine maintenance on their 75 pound capacity commercial tumble dryer. The front and back lint screens were removed and scrubbed with wire bristles to dislodge built up lint. The belt drive system was then inspected for wear and adjusted for proper tension. The thermostat calibration, moisture sensors, shock absorbers and door gasket were all verified to be within factory specifications. Finally, a 30 minute test cycle was run with no issues identified.
