Learn about the rectifier circuit in your exercise bike that converts AC to DC power. A fault here can cause a dead machine or blown fuses.
What is a Rectifier and Why Do Bikes Need It?
Explaining that bikes with AC adapters still need an internal rectifier to create stable DC voltage for the electronics.
Symptoms of a Failed Rectifier
A shorted rectifier can cause the AC adapter to shut down or an internal fuse to blow, leading to a dead bike.
Location of the Rectifier Circuit
The rectifier is found on the main control board, right after the power input jack.
