Look at the control panel to spot a WTG86403UC. It has both a rotary program selector and touch controls, a hybrid from a transitional stretch of Bosch’s laundry designs, and it dates the machine. The dryer is a discontinued 300 Series condensation model with a drum of 4.0 cubic feet.
Under the panel it is conventional: the usual Bosch drum, condenser and NTC sensor, in a vent-free body 23 1/2 inches across with a condensate reservoir and a condenser that cleans itself. Nothing about it is exotic, and the wear points follow the usual order.
The rotary selector switch wears first on many, so the dial skips programs as you turn it. The condenser collects lint through years of service. And the door catch can wear until the door pops open mid-cycle. We check the selector, clean the condenser, and test the catch and striker in one visit.
Yes. The switch sitting behind the dial wears out and is swapped as a part, as on any appliance with a rotary selector. We confirm the cause before ordering anything.
The door catch or its striker has worn out and cannot hold the door closed. The part is small, yet a dryer that keeps opening cannot complete a drying program.
No. It is simply how Bosch built this generation. Knowing it helps with identifying the model and the parts it uses.
