Exercise Bike Relay and Switching Circuit Failures
Hearing a click but the resistance doesn't change? Your bike's relay may have failed. Learn how these switching circuits work and how they are repaired.
The Role of Relays on a Bike Controller
Relays are electromagnetic switches that allow the low-power console buttons to control high-power components like the resistance motor.
Symptom: The "Click of Death"
Hearing a click from the control board when you try to change resistance, but nothing happens, is a classic sign of a failed relay.
Why Do Relays Fail?
The internal contacts get worn or burnt from electrical arcing over thousands of cycles.
Diagnosing and Replacing a Relay
Replacement requires desoldering the old relay from the board and soldering in a new one, a task for a skilled technician.
