Blomberg Dryer Will Not Turn On

Blomberg Dryer Initial Checks Before Troubleshooting

When your Blomberg dryer fails to turn on, there are a few simple checks to resolve the issue quickly without needing a dryer professional. Start by ensuring the dryer is securely plugged into the outlet and check for any damage to the plug. Next, verify that the dryer’s circuit has not tripped on the main fuse box. Lastly, test the outlet with a voltage tester to confirm whether it’s functioning correctly. This guide will explore the above steps and additional, more in-depth troubleshooting that are common for Blomberg dryers.

Power Source and Electrical Outlet

The first step is to check the power source and electrical outlet, which are often overlooked yet common culprits. Ensure the dryer is firmly plugged into the wall socket; sometimes, plugs can loosen over time or not be fully inserted. If your model uses a 240-volt plug, confirm it’s correctly and securely connected. Use a voltage tester to check if the outlet is delivering power, as a faulty outlet could be why your dryer isn’t powering up. If the outlet is not functioning, it might mean there’s a severe issue with your home’s electrical wiring. 

Circuit Breaker and Fuse Box

Another critical area to check is the circuit breaker and fuse box. First, locate your home’s circuit breaker or fuse box and identify the switch or fuse corresponding to your dryer. It’s not uncommon for a dryer’s breaker to trip due to the high energy consumption, especially in older homes or when multiple appliances are used simultaneously.

If you discover the dryer’s circuit breaker has tripped, flip it back to the “On” position. However, suppose it trips again shortly after resetting. This is a clear indicator of a more severe electrical issue, such as an overloaded circuit or a potential short circuit within the dryer itself. In the case of a fuse, check if it has blown—indicated by a broken filament or a blackened appearance—and replace it with a new one of the same type and rating.

Multimeter as a troubleshooting aid device

When trying to resolve your Blomberg dryer issue, a multimeter can help diagnose electrical problems within the appliance. A multimeter measures voltage, current, and resistance, essential for identifying potential electrical breakdowns. For example, if your dryer isn’t starting, you could use a multimeter to check the continuity of the door switch and thermal fuse—two components that commonly cause startup issues when faulty.

To use a multimeter effectively, start by setting it to the continuity setting, which will check if a circuit is complete. A good continuity test will typically emit a beep if the circuit is unbroken. No beep usually indicates a break in the circuit, suggesting a component failure. For instance, test the thermal fuse located typically near the dryer’s heat source; no continuity here suggests the fuse has blown due to overheating and needs replacement.

In addition to continuity, you can use the multimeter to measure the voltage output at the outlet to ensure it matches the specifications required by your Blomberg dryer. This is crucial because insufficient or excessive voltage can prevent the dryer from starting.

Inspecting the Receptacle

Testing electrical components on your Blomberg dryer is essential for troubleshooting. Always ensure the dryer is unplugged to avoid electric shock.

Signs of Receptacle Issues

Checking the receptacle can often be a simple but overlooked step in troubleshooting. A faulty receptacle can prevent your dryer from receiving the power it needs. Start by visually inspecting the outlet for wear or damage, such as burn marks, discoloration, or melting.

Testing the Receptacle

Testing the receptacle includes checking if the outlet feels loose or the plug doesn’t fit securely. A loose plug can lead to an inconsistent power supply, causing the dryer to fail to turn on or lose power intermittently. If you suspect the receptacle might be the issue, safely test the outlet with a multimeter or a voltage tester to confirm that it is receiving and delivering the correct voltage. If you are unfamiliar with using these tools, it’s essential to refer to the manual or consult a professional to avoid electric shock.

Symptoms of a Faulty Control Board

A clear indicator of a faulty control panel is unresponsiveness. It’s essential first to ensure that there are no loose connections, which can sometimes be resolved by simply reseating cables. If basic checks don’t fix the problem, a continuity test with a multimeter can help diagnose faulty wiring or components. However, if the control panel is found to be defective, replacement is typically the most effective solution, as repairing electronic components can be complex and costly. Consulting a professional technician is advisable for accurate diagnosis and safe repairs, especially for handling intricate electronic work safely and effectively.

Diagnosing Start Door Switch Problems

This switch is responsible for initiating the dryer’s operation, and if it’s defective, the dryer will not start even if all other components are functioning correctly. Begin by ensuring that the dryer is unplugged to prevent any electrical hazards. Locate the start switch, typically found behind the dryer’s control panel. Use a multimeter set to the continuity setting to test the switch. Connect the multimeter to the switch terminals and press the start button. A properly functioning start switch will show continuity, meaning the electrical path is complete. If the multimeter does not show continuity when the button is pressed, the start switch is faulty and needs to be replaced.

Replacing a defective start switch involves removing the control panel cover and disconnecting the switch from its housing. When installing a new switch, ensure all connections are secure, and the switch is firmly in place before reassembling the control panel. Always refer to the dryer’s manual for specific details on the switch’s location and replacement procedures. Handling these repairs yourself can be manageable, but if you’re unsure or uncomfortable with electrical components, it’s wise to call a professional technician. Regular maintenance and timely repair of the start switch will help keep your dryer running efficiently and prevent further issues related to starting problems.

Checking Internal Wiring

Start this check by unplugging the dryer to avoid any risk of electric shock. Access the internal components of your dryer by removing the back panel or service panel, depending on your model. Look for any wear, damage, or disconnection in the wiring. Common issues include frayed wires, loose connections, or blackened areas that suggest short circuits.

Use a multimeter to test the continuity of the wires. Each connection should be secure and free from corrosion. Pay particular attention to the terminals connecting major components like the heating element, thermostat, and motor, as these are high-stress points that can fail over time.

Professional Help: When to Seek It

Consider seeking professional help if you’ve conducted basic troubleshooting, such as ensuring the appliance is plugged in, the circuit breaker hasn’t tripped, and there are no apparent signs of damage. This is particularly crucial if you suspect the problem might be related to the dryer’s internal electronics or wiring, which can be complex and potentially hazardous to repair without proper training and tools.


As we conclude our exploration of troubleshooting a Blomberg dryer that fails to power up, it’s essential to emphasize a structured approach. Start with basic diagnostics, such as checking power connections and verifying door switch functionality, and progress to more intricate system checks if needed. Should these initial efforts not resolve the issue, engaging a professional technician is advisable to ensure accurate diagnostics and safe repairs. Regular upkeep and recognizing when to seek expert intervention save you time and expense and help maintain the efficacy and longevity of your appliance.
