Hey there! As a supplier of Tangential By Pass BLDC Blowers, I've seen my fair share of issues with these nifty devices. One of the most common problems customers come across is when their blower just won't start. In this blog, I'll walk you through some steps to troubleshoot a Tangential By Pass BLDC Blower that doesn't start.

Check the Power Supply

The first thing you gotta do is make sure the blower is getting power. Sounds obvious, right? But you'd be surprised how many times it's just a loose connection or a tripped breaker. Start by checking if the power cord is plugged in properly. Give it a little wiggle to see if that makes a difference. If it's plugged into a power strip, make sure the strip is turned on and not overloaded.

Also, check the circuit breaker. If it's tripped, reset it and see if the blower starts. Sometimes, a short circuit or an overcurrent can cause the breaker to trip. If the breaker keeps tripping, there might be a more serious issue with the blower.

Inspect the Motor

The motor is the heart of the blower, so it's important to check it for any signs of damage. Look for any visible signs of wear and tear, such as frayed wires or burnt components. If you see any damage, it's best to replace the motor.

You can also try testing the motor with a multimeter. Set the multimeter to the resistance setting and measure the resistance between the motor's terminals. If the resistance is too high or too low, it could indicate a problem with the motor.

Check the Control Board

The control board is responsible for controlling the speed and operation of the blower. If the control board is malfunctioning, the blower might not start. Look for any visible signs of damage on the control board, such as burnt components or loose connections.

You can also try resetting the control board. Some control boards have a reset button that you can press to reset the board. If the control board is still not working, it might need to be replaced.

Look for Obstructions

Sometimes, the blower might not start because there's an obstruction in the airflow. Check the intake and exhaust ports for any debris or blockages. If you find any, remove them and see if the blower starts.

You can also check the impeller for any damage or blockages. The impeller is the part of the blower that moves the air. If it's damaged or blocked, it won't be able to move the air properly.

Check the Wiring

The wiring is another important part of the blower. Make sure all the wires are connected properly and there are no loose connections. If you see any loose wires, tighten them up.

You can also check the wiring for any signs of damage, such as frayed wires or burnt insulation. If you find any damage, it's best to replace the wiring.

Try a Soft Reset

If you've tried all the above steps and the blower still won't start, you can try a soft reset. To do this, turn off the power to the blower and unplug it from the power source. Wait for a few minutes and then plug it back in and turn it on. Sometimes, a soft reset can fix minor issues with the blower.

Consider Professional Help
