Gaggenau Dryer not heating
If your Gaggenau dryer is not heating, the most common culprit is a blown thermal fuse caused by restricted venting, so check and clean the exhaust before you replace the fuse and test it with a multimeter for continuity. Next on the list is a faulty drive motor centrifugal switch; the motor may run while the heat circuit never closes, and because most centrifugal switches are not sold separately you’ll likely need the complete motor. On gas models the gas valve solenoids are a frequent cause: if the igniter glows but the gas never lights, the solenoids are likely bad and should be replaced as a set. Also double-check the cycle and heat settings—an accidental no-heat or air-fluff selection is an easy miss. Finally, a burned-out igniter will stop ignition on gas dryers and can be checked for continuity and swapped out if open. If you need parts, enter your model number on RepairClinic.com to find the exact replacement part for your dryer so you get the right thermal fuse, motor, solenoid set, or igniter.
01 - Gaggenau Dryer Thermal Fuse
The thermal fuse is a safety device designed to protect the dryer from overheating. The fuse is located on the blower housing or at the dryer’s heat source such as the heating element on electric dryers or at the burner on gas models. The fuse should be closed for continuity meaning it has a continuous electrical path through it when good. If overheated the fuse will have no continuity meaning the electrical path is broken and the fuse has blown. A multimeter can be used to test it for continuity. Be aware that a blown thermal fuse is an indication of a restricted exhaust vent from the dryer to the outside. Always check t...

02 - Gaggenau Dryer Drive Motor
Most dryer drive motors have a centrifugal switch that energizes a start winding when the motor is first started and closes a heat cycle contact to allow the heat source to work. If the motor's centrifugal switch is faulty, either the motor won’t run or the motor will run but the dryer won’t heat. Since most centrifugal switches are not sold separately, the entire motor will need to be replaced if the switch is defective.

03 - Gaggenau Dryer Gas Valve Solenoid
Gas dryers have two or more gas valve solenoid coils. The gas valve solenoids open the gas valve ports to allow gas to flow into the burner assembly. If a gas valve solenoid fails, the dryer won’t heat. To determine if one or more of the gas valve solenoids has failed, check the igniter. If the igniter glows and goes out but does not ignite the gas, the gas valve solenoid is defective. If one or more of the gas valve coils are defective, we recommend that you replace them as a set.
Highly Likely
04 - Incorrect cycle settings
Ensure the dryer is set to the appropriate heat setting. The setting may have been inadvertently changed to a non-heat option.
Highly Likely
05 - Incorrect cycle selected
The dryer setting may have been inadvertently changed to a non-heat option. Confirm the dryer is set to a proper heating option such as "Regular" or "Heavy" to see if that improves drying performance.
Highly Likely
06 - Gaggenau Dryer Igniter
The igniter uses heat to ignite the gas in the burner assembly. If the igniter is not working, the gas will not ignite, preventing the dryer from heating. To determine if the igniter has burned out, use a multimeter to test the igniter for continuity. If the igniter does not have continuity, replace it.
