3 Ways How To Fix Bosch Dryer Not Starting?

Your Bosch dryer is one of the most important appliances in your home, and when it stops working, it can be a major inconvenience. Fortunately, most dryers have a simple design and are easy to troubleshoot before you need to call a technician.
Here are some tips on how to fix a Bosch dryer that’s not starting.
- Check to see if the dryer is plugged in.
- Check the start switch.
- Make sure the door is closed completely.
- Confirm that the door switch is working correctly.
- Check for a clogged lint trap and clean it out.
- Check for a clogged vent.
- Ensure the belt and rollers are spinning freely.
- Try resetting the breaker.
- Check the thermal fuse.
- Check the drive motor.
- Reset your dryer’s Electronic Control Module (ECM).
- Call a technician.
These are the most common issues that can cause your Bosch dryer to stop working. Read on for a more thorough guide that expands on these tips.
Before doing anything else, ensure that the dryer is getting power. Check the outlet to see if it’s plugged in and test another appliance in the same outlet to ensure it’s working.
The majority of the time, when a dryer doesn’t start, it may be because you didn’t plug it in all the way. Tug at the cord to ensure it’s plugged into the outlet.
The start switch is a small button or lever that you press to start the dryer. Over time, this switch can become worn out, preventing the dryer from starting. If the start switch is defective, the dryer won’t start.
Press the start switch while the dryer is plugged in to test it. If you hear a clicking sound, then the switch is likely fine. If not, the switch will need to be replaced.

Most dryers have a switch that prevents them from turning on if the door is open. The switch is a safety feature that prevents the dryer from starting if the door isn’t closed.
If the door isn’t closed, the dryer won’t start. Close the door completely and try starting the dryer again.
The door switch is designed to keep the dryer from starting if the door is open. To determine if the door switch is working properly, close the door and press the start button with the door closed.
Alternatively, you can test your dryer’s door switch with a multimeter.
If the dryer still doesn’t start, the door switch is probably faulty and will need to be replaced.

If the lint trap isn’t catching lint, it will overload your dryer with lint. Overloading causes the motor to burn out sooner than it should.
Check the lint trap and clean out any lint that is stuck in it. If the lint trap is clogged with lint beyond what you can clean out, you will need to replace the lint trap.
Some models come with a lint trap that needs to be washed periodically. If your dryer is one of these models, you may want to service the lint trap regularly to prevent a clog.
If the vent is clogged, the dryer won’t be able to get rid of the heat, and it will overheat. Overheating can cause the dryer to stop working.
Check the vent and make sure it’s clear of any lint or debris. If the vent is clogged, you’ll need to clean it out. You can purchase a dryer vent cleaner online or at your local home improvement store.
If the problem persists, you may need to replace the vent.

The dryer belt may be worn out or broken. If that is the case, it won’t be able to turn the drum. Check the belt and make sure it is moving freely.
The rollers help support the drum and keep it from wobbling. If the rollers are worn out, they can cause the drum to wobble and make noises. Check the rollers and make sure they are spinning freely.
Make sure that the rollers are not frozen in place. If they are, you’ll need to break them free and lubricate them with some dryer lubricant.
You will need to replace the belt and rollers if they are worn out. This is a fairly easy repair that you can do yourself.
