proceed according. God bless you Be aware that the resistance is often the part that requires repair. Resistance is managed magnetically, so often if the machine is working, but the resistance isn't setting correctly or at all, check the bolts that secure the magnets. If they are loose, the resistance will slip. If the bolts are fine, check the magnets themselves by using a refrigerator magnet and see if it is attracted or repelled by the your fridge magnet. If not, the magnets have de-magnetized and need to be replaced.

Realign sensor if necessary ( 1/8" clearance between sensor and flywheel) if still error 3 then check the sensor with a multi meter unplug sensor leads attach meter to sensor connectors.

It is possible that the crank arms are not seated correctly on the bottom bracket spindle, causing them to be misaligned. Try removing the crank arms and re-installing them, making sure that they are properly aligned with each other and with the bottom bracket spindle. If that doesn't work, there may be an issue with the bottom bracket itself, in which case it may need to be replaced. You can also check the manual for your Airdyne AD-6 to see if there are any specific instructions for adjusting the crank arms.
