Understanding Warner Electric Brake Magnets
Warner electric brake magnets are electromagnets that activate the brakes on your trailer when you apply the brakes in your tow vehicle. They work in conjunction with a brake controller, which sends an electrical signal to the magnets, creating a magnetic field. This field pulls the magnet towards the brake drum, engaging the brakes. Understanding this basic principle is the first step in effective troubleshooting. These magnets are designed for durability and reliability, but like any mechanical component, they can experience wear and tear over time.
Common Problems with Warner Electric Brake Magnets
Several issues can arise with Warner electric brake magnets, ranging from simple wear and tear to more complex electrical problems. Some of the most common problems include:
- No Power to the Magnets: This can be caused by a faulty brake controller, a blown fuse, or damaged wiring.
- Weak or Uneven Braking: This could indicate a worn-out magnet, a low voltage issue, or an improperly adjusted brake controller.
- Overheating Magnets: Overheating can be a sign of a seized or sticking magnet, incorrect wiring, or excessive braking.
- Magnet Not Releasing: A magnet that fails to release can be caused by a mechanical issue within the magnet itself or a problem with the brake controller.
- Intermittent Braking Issues: This can be one of the most challenging problems to diagnose and can be caused by a variety of factors, including loose connections, corroded wires, or a faulty ground connection.

Diagnosing Warner Electric Brake Magnet Problems
Diagnosing the issue with your Warner electric brake magnets requires a systematic approach. Here’s a step-by-step guide to help you identify the root cause:
- Check the Brake Controller: Ensure the brake controller is properly installed and adjusted. Refer to the manufacturer’s instructions for specific guidance.
- Inspect the Wiring: Carefully examine the wiring harness for any signs of damage, corrosion, or loose connections. Pay particular attention to the ground connection, which is crucial for proper operation.
- Test for Power: Use a multimeter to check for voltage at the brake magnet connector. This will determine if the magnets are receiving power from the controller.
- Measure Magnet Resistance: Using a multimeter, measure the resistance of the brake magnets. Compare the readings to the manufacturer’s specifications to identify any faulty magnets.
- Inspect the Brake Drum and Shoes: Remove the brake drum and inspect the brake shoes for wear and tear. Check for any signs of overheating or damage to the magnet itself.
