Bosch Dryer controls don't work
When your Bosch dryer controls are not working, the most likely causes are simple mechanical failures you can check and fix. Start by inspecting the control, timer, and selector knobs—cracked or stripped knobs often just slip on the switch stem and leave the dryer knob not working or not turning, so replacing the knob usually restores function. If the entire display or timer is dead, check the power cord for breaks, melted insulation, or blackened terminals and replace the cord if damaged. If the problem is a single button, like the start button not working, and the door switch tests good, a blown thermal fuse is a common cause; use a multimeter to check for continuity and replace the fuse if it reads open. These checks cover the most likely reasons your dryer controls are not responding, and they keep the repair straightforward for a capable DIYer. Enter your model number on RepairClinic.com to find the exact replacement knob, power cord, thermal fuse, or other parts that fit your dryer.
01 - Bosch Dryer Selector Knob
A dryer selector knob needs to be able to engage and rotate the selector switch stem for that control to work. If the knob is cracked or stripped out and just slips on the stem a new knob will need to be installed to properly engage the switch.

02 - Bosch Dryer Timer Knob
The dryer's timer knob needs to be able to engage and rotate the timer stem for the control to work. If the knob is cracked or stripped out and just slips on the stem a new knob will need to be installed to properly engage the control.
Highly Likely
03 - Bosch Dryer Control Knob
A dryer control knob needs to be able to engage and rotate the switch stem for that control to work. If the knob is cracked or stripped out and just slips on the stem a new knob will need to be installed to properly engage the switch.
Highly Likely
04 - Bosch Dryer Power Cord
If the whole dryer display or timer is not working, the dryer's power cord could the source of the problem. Inspect the cord for any breaks or burn marks near the terminals. If the terminals appear blackened or wires are exposed through the cord's insulation, you should replace the power cord with a new one.
Highly Likely
05 - Bosch Dryer Knob
A dryer control knob needs to be able to engage and rotate the switch stem for that control to work. If the knob is cracked or stripped out and just slips on the stem a new knob will need to be installed to properly engage the switch.
Highly Likely
06 - Bosch Dryer Thermal Fuse
If just the start button is malfunctioning and you've confirmed the door switch is working properly, then it's possible the thermal fuse has blown. You can use a multimeter to test the fuse for electrical continuity. If the thermal fuse has no continuity, you'll know it has blown and will need to be replaced.
