The most important tip for elliptical repair is to locate a manual for the malfunctioning unit, since every elliptical machine has a somewhat different design. There are a few general items to check any time an elliptical machine is malfunctioning, such as lubrication points and bearings, the power supply, electrical connections, and the tension band. If an elliptical machine is making a lot of squeaking or grinding noises, that usually indicates the rails and wheels require lubrication, and if the pedal arms are stuck in place that indicates the bearings are probably frozen. Console display issues are typically the result of low batteries or a bad power supply connection, and many other types of elliptical repair also involve loose or damaged connections of one kind or another.
Elliptical machines are exercise devices that are designed to provide a workout for both the upper and lower body. They typically consist of foot pedals that are mechanically connected to movable hand grips. Some models provide mechanical resistance through the use of tensioner bands, while others have electronic resistance systems or motors. Since there are so many different types of these machines, the first step in any elliptical repair procedure is to locate an appropriate manual that identifies all of the internal components and systems. It is possible to make some elliptical repairs without access to the proper manual, though that can be more difficult.
The next step in any elliptical repair procedure is to identify the problem. One of the issues most commonly associated with malfunctioning elliptical machines is some type of noise, which is typically described as a squeak or grind. If an elliptical machine is making squeaking noises, then there is a good chance that it requires lubrication. This can typically be accomplished by extending the guide rails, and applying a polytetrafluoroethylene (PTFE) lubrication spray to both the wheels and the guides. Grinding noises usually indicate a brake mechanism that was improperly aligned at the factory, which may not be easily user-serviceable.
Another common type of elliptical repair is related to the resistance systems commonly found in these exercise devices. If an elliptical trainer with a mechanical resistance system is not offering sufficient resistance, that can often be remedied by adjusting the tension band. These band can become disconnected, or even break in some instances, in which case they often need to be replaced. Elliptical trainers with electronic resistance systems may suffer from burned out motors, though a problem with the power supply or electrical connections is more likely to be the culprit. Power supply and battery problems can also result in console display issues, fluctuating heart rate readings, and other similar malfunctions.
