Bowflex Max Trainer, Is the Servo Motor Bad?

Dealing with a malfunctioning servo motor on a Bowflex Max Trainer can be frustrating. You ask yourself what went wrong? Is my servo motor bad?

Here's a breakdown of how to identify potential issues and what to check:

Symptoms of a Failing Servo Motor:

Resistance Issues:

• The most common symptom is inconsistent or non-responsive resistance levels. You might find that the resistance doesn't change when you adjust it on the console, or it may change erratically.
• The machine might display a "brake error" on the console.

Unusual Noises:

• Clicking or grinding noises coming from the base of the machine, particularly when the machine powers on or when resistance levels change, can indicate a problem with the servo motor.

Lack of Resistance:

• In some cases, the machine might offer no resistance at all.

Intermittent Problems:

• The problem could be intermittent, where the resistance works sometimes and not others.

Checks and Tests:

If you are not comfortable with any of these checks or tests, it is best to contact a qualified fitness equipment technician.

1. Visual Inspection:

• Cables and Connections: Carefully inspect the cables connecting the servo motor to the console. Ensure they are securely plugged in and that there are no visible signs of damage. You may want to disconnect and reconnect the cables to make certain of proper connection.
• Servo Motor Alignment: Where possible, visually inspect the servo motor and its associated components. Check for any signs of physical damage or misalignment. Click here to to learn more about alignment.
• Brake Magnet Alignment: The brake magnet alignment is very important. With the machine at max resistance, verify the brake magnet is aligned correctly with the brake disk. Click here to learn more about brake magnet alignment.

2. Listening:

• Pay close attention to any unusual noises coming from the machine, especially when changing resistance levels. Clicking, grinding, or skipping sounds can indicate a problem with the servo motor.

3. Resistance Testing:

• While using the machine, try changing the resistance levels. If the resistance doesn't change or if it changes erratically, this is a strong indication of a potential servo motor problem.

4. Console Connections:

• Sometimes the problem is not the motor itself, but the connection at the console. So checking the connection at the console is also a very good idea. Make certain the cable is properly seated in position. Check the cable for any breaks, crimping, or damage. Check the cable for continuity.
