If your Gaggenau dryer won't stop, keeps running after the cycle ends, or won't stop spinning intermittently, start with the most likely issues: restricted airflow from a clogged vent or duct is the top cause and will make the dryer run longer and heat up more than normal, sometimes producing a burning smell. Next check the settings; an anti-wrinkle or tumble option will intentionally tumble clothes every few minutes after a cycle. A blocked or worn blower wheel is another common reason the machine takes too long and may wobble or reduce vent airflow, so remove the vent and feel the exhaust while you run a cycle. Less likely but worth confirming are incoming power problems such as a loose plug or a tripped breaker that cause odd run/stop behavior, and finally a faulty control board that can allow the dryer to run past its set time. If you need a replacement blower wheel, control board, vent kit, or another part, enter your model number on RepairClinic.com to find the exact part for your dryer.
01 - Air Flow Problem
If the vent line is clogged or partially clogged, it will restrict the airflow through the dryer, substantially increasing the drying time and cabinet temperature and potentially causing a burning smell. To ensure proper dryer performance, you should clean your dryer's venting system at least once per year.

02 - Anti-wrinkle cycle option selected
Most dryer models have an anti-wrinkle cycle option that can be selected to reduce wrinkles. When selected the dryer drum will tumble the clothes every few minutes after the cycle is completed to help keep wrinkles from occurring. If this option was inadvertently selected the dryer will intermittently run until the clothes are removed.

03 - Gaggenau Dryer Blower Wheel
The blower wheel draws air through the dryer and pushes the air out the vent. Clumps of lint, socks, and small articles of clothing can escape the lint filter and get caught in the blower wheel. In addition, the blower wheel sleeve can wear out, allowing the blower wheel to wobble on the motor shaft. If the blower wheel is obstructed or defective, it may take too long to dry clothes. To determine if the blower wheel is working properly, remove the dryer vent and assess the strength of the air flow. If the air flow is weak, check the blower wheel for obstructions. If no obstructions are present, try rotating the blower whee...l by hand. If the blower wheel wobbles as it turns, replace it.

Confirm a circuit breaker has not tripped and the power cord is plugged tightly into the wall receptacle. A loose plug can provide intermittent power to the dryer and cause it to spinning stop during the cycle.

05 - Gaggenau Dryer Control Board
A dryer's control board controls the voltage being sent to all of the appliance's electrical components. If there's no obstruction in the dryer's venting and the dryer is heating to the proper temperature, it's possible the control board is defective and allowing the appliance to run longer than it should. You can inspect the board for signs of damage or a shorted component. You can also use a multimeter to test for voltage reaching the drive motor after reviewing the dryer's wiring diagram.
