The CompuTrainer Hardware is pretty trouble free. Due to its complexity, many symptoms are similar even though the causes may be from a variety of issues. The following issues are the most frequently asked.
A: The fuse in the Power Supply has blown. Notify the RacerMate Service Department for fuse replacement recommendations.
A: The Load Generator is an electromagnetic eddy-current brake. The magnetic resistance is calculated on the fly based upon things such as your weight and speed. It is assumed by the software that the Load Generator is working correctly, but if it isn't, the resistance will be wildly different than what you're used to. Contact RacerMate Service for information on repair.
A: The only moving item inside the Load Generator is the eddy disc. It spins, perfectly spaced, between the magnetic poles. If the disc is overheated it can warp, and as such, hit one of these magnetic poles. You'll need to contact RacerMate Service for repair information. Once repaired, it is advised to add an external cooling fan as mentioned in the Care and Maintenance section.
A: The ear clip Heart Rate Sensor is likely corroded from the constant contact with your sweaty ears. All attempts have been made to minimize the potential of failure due to this. Contact RacerMate Service for replacement information.
A: The speed of the CompuTrainer is measured inside the Load Generator. It is determined mathematically using the speed of the roller and the diameter of the roller. Your cycle computer measures speed based upon tire circumference. Because the roller of the CompuTrainer presses into the tire more than it would while riding on the road, the actual tire circumference will be slightly smaller on the CompuTrainer than on the road. Rest assured that the speed on CompuTrainer is actual speed.
My Cadence Sensor doesn't read RPM or SpinScan. Why?
A: It may be necessary to move the Cadence Sensor fore or aft until an RPM signal is received on the handlebar Control Module. (If the magnet passes the exact center of the Cadence Sensor, it may not produce a signal). Maximum clearance between the Magnet and the Cadence Sensor should be 1/8" - 3/16".
A: Chances are you either have a tire with very pronounced "ribs" inside that are chafing the tube at its seam. Take the tire off the rim and feel around the inside of the tire opposite where the tread is attached and verify whether it is smooth inside. If it's not smooth, replace the tire. Other causes are cheap tubes, an under inflated tire, too much press-on force, and out-of-round rims. The tires we use in our testing are made by Michelin and have no visible tread, although this isn't to say that you must use this tire. You should not need to concern yourself with this until you do have problems.
