Gone are the days of only enjoying the latest action-packed blockbuster at the theater. Thanks to subwoofers you can have your own home theater system in your living room. But when the subwoofer is not working, what can you do?

If your Yamaha subwoofer is not working, check all the wires and connection points running between any amplifiers, receivers, or other speakers. Make sure the cables are securely connected to the correct ports. Inspect the wires for any signs of visible damage.

It is very frustrating when the subwoofer does not work. But before you start shopping for a new subwoofer, here are some things to troubleshoot the problem.

Oftentimes the reason why a subwoofer is not working is that there is an issue with the connections or the power source. The first place to start is to make sure the subwoofer is receiving power.

Yamaha Subwoofer Not Turning On

If the Yamaha subwoofer is not turning on, make sure the power cord is securely connected to its power source. A loose connection will disrupt the electrical current, Connect the subwoofer to a wall outlet instead of a power strip.

The subwoofer will not detect the signal to power on if the front of the subwoofer is blocked. Remove any objects that are blocking the front and the bass reflex port of the subwoofer.

Wireless connections are a thing of beauty. You have everything connected to the network without the hassle and ugliness of wires. What does it mean if your Yamaha subwoofer is not connecting?

If your Yamaha subwoofer is not connecting, move the subwoofer closer to the router. Moving the subwoofer closer will increase the signal strength and will stabilize the signal if it is weak. Make sure the subwoofer and router are connected to the same network.

When trying to connect your subwoofer to another speaker, turn off the other speaker and press the minus (-) button on the subwoofer volume remote. Continue holding the button until the standby light starts flashing. The light means the speaker and subwoofer are now connected.

The subwoofer will keep turning off if the system and menu settings have been adjusted. Make sure the subwoofer is associated with the proper audio input selection. The subwoofer will also appear to not be working if the output setting has been adjusted too low.

You are enjoying your subwoofer when all of a sudden there is no sound. Why does the Yamaha subwoofer have no sound?

If your Yamaha subwoofer has no sound, make sure the speaker is set to Small in the speaker setup menu. The subwoofer speaker volume in the setup menu and the volume on the back of the subwoofer both need to be turned up.

The subwoofer cone can become damaged when they receive too much power or a distorted signal. Replacing a damaged subwoofer cone may seem simple enough but it is something that should be left to the professionals.

If you are not familiar with how to replace the cone, you risk making the problem worse or causing further damage.


When our appliance suddenly stops working, our first thought might be to check the fuse. We don’t think of our electronics as having fuses though.

Just like a fuse will blow to protect an appliance, the same is true for the fuse in a subwoofer. There are a variety of reasons why the fuse will blow.

The fuse will blow if the subwoofer has experienced a surge in electricity, if the volume has been used on the max setting for an extended period of time, if the wrong amount of voltage is used, or if the fuse itself is defective. Just to mention a few.

Fuses on a subwoofer are often located within the speaker enclosure, which is in line with the subwoofer wires. If the subwoofer has a dedicated amp, the fuse will be located there.

Depending on the type of fuse, it will either be in a tube located on a wire or in a spring-loaded holder. The holder will be black, white, or opaque.

Once you find the fuse you will be able to take it to your local stereo repair shop and find the right replacement fuse.

Yamaha Subwoofer Stuck On Standby

The indicator light keeps flashing on the subwoofer signaling it is stuck on standby. Why is the subwoofer stuck on standby?

If your Yamaha subwoofer is stuck on standby, adjust the trim level on the receiver. The subwoofer will not work correctly if the voltage from the receiver is too low. Go into the receiver’s audio settings. The volume level of the subwoofer needs to be in the negative numbers.

Bad communication between the center unit and the subwoofer will also prevent the subwoofer from connecting. Move the center unit and subwoofer closer to each other.

A recent surge in power could have overloaded the subwoofer’s circuitry. Unplug the subwoofer and disconnect any other wires or connections. Let the subwoofer rest without power for at least 30 seconds.

Once the subwoofer has been able to drain the excess electricity from its circuitry, plug the subwoofer back in and turn it on. The standby light should now be off.

Yamaha Subwoofer No Power

The subwoofer is connected and plugged in but the power indicator light is not illuminated. Why does the Yamaha subwoofer have no power?

If your Yamaha subwoofer has no power, inspect the power cord and connection wires. Make sure the power cord has no visible signs of damage. The wire connections need to be tightly fitted to the correct ports. Inspect the ports for any bent, broken, or missing pins.

We take for granted that we can plug things in and they just work. When that doesn’t happen, it can be stressful. Sometimes, though, the problem has nothing to do with the subwoofer.

Lamp Test

Most subwoofers have a LED indicator light that is illuminated when it is receiving power. If this light is not lit, the subwoofer is not getting power.

If the subwoofer is connected to a wall outlet, do a lamp test. Unplug the subwoofer and then plug in a small lamp. If the lamp does not work, the outlet is not receiving power.

If the lamp works, then you need to investigate the subwoofer more closely. Make sure the subwoofer power cord is securely connected to the power source. A loose fitted connection will disrupt the flow of power and the subwoofer will not work.
