Eight parts guides, and one of them exists to correct an assumption: the igniter entry explains that a ventless Bosch dryer does not work the way a gas dryer does, so the part people search for is often not the part their machine has. The rest are the control board, the door latch, the lint filter, the heating element, the motor, the switch and the thermostat — the set that covers a dryer that will not heat, will not start, or will not turn.
Read the igniter guide first if that is the part you came for, because establishing which machine you own changes every other decision in the hub. After that, no heat is a chain rather than a part: the thermostat and the heating element are checked in sequence, since a thermostat that has opened and an element that has failed produce an identical complaint at very different prices. A dryer that will not start goes to the door latch and switch instead.
The heating circuit and the terminal block behind it are where a homeowner should stop on any electric dryer — that is 240 volt work, and the cord and block have to be correct rather than nearly correct. Lint restriction is the second limit, since a starved airflow path is a fire risk and also what opens thermostats in the first place. Bosch dryer service is available from EasyBear in Sacramento and across the Bay Area.
