There may be two different issues with your setup to consider for your Reese Towpower controller. If your brakes were recently serviced, it could be the case that the brakes were adjusted too tightly. If you think this may be the case, I went ahead and linked a FAQ article below.

For the next troubleshooting route, it is possible that your trailer brake magnets are damaged. I also linked a helpful article that walks you through testing your magnets. The article lists a diagram that shows how much voltage and amperage you need depending on your brake specs. If you need a voltage reader to conduct the measurement, I recommend the # PTW2992.
