20 Most Recent Schwinn Airdyne Ad4 Upright Bike Questions & Answers


The age of the machine is not as big of a replacement parts hinder as is Schwinn going through so many buy outs since 1988.

One of the best exercise repair parts on online is FitnessRepairParts.com. They have consoles which are similar to your generation of machine for 170.00 - 240.00

Otherwise schwinn was most recently owned by Nautilus/Bowflex/LAMAR fitness and they may be able to help through their website.

Sorry, I don't have a great source of imformation to help with. I repair Schwinn exercise and it has become very hard to find parts recently as the new generation of AEROdynes are very different. Although, up until maybe 1-2 years ago, nothing had changed for 30 years.

Alternatively, search craigslist and ebay. You may have to buy an entire unit to get the part you desire. Often they have a drive mechanism worn out which devalues them to the seller, but has minimal to do with your search.

Good Luck.

I searched the internet using https://www.google.com and could not locate a manual for that model Stair stepper.

I did find a free manual for possibly a similar model 305p:

Our Schwinn 130 worked fine for a year then the resistance setting got stuck. We took it apart and found that the bolt that holds the magnet arm was too tight and preventing it from moving it to the highest resistance setting. We loosened the bolt a bit and added some WD40 and it works great now.

Perhaps. Google (schwinn)(230)(manual) without parens OR contact Schwinn directly to request it.

Generally, the L5 error indicates that the controller circuit is not receiving any data feed from the speed sensor of your treadmill.

When you start the treadmill (that has a L5 error), it will start briefly and then stop. It stops due to a built-in safety feature i.e. no speed data = stop motor.

To fix this issue:
Remove the motor cover, the speed sensor is located near the small wheel that has the small belt that connects with the roller. The sensor is a little (usually black) tube like thing.

In 90% of the cases, the sensor position has shifted (usually happens if you're not too careful when removing or fitting the motor cover). The sensor position is sensitive with respect to the two magnets embedded amongst the spokes of the small wheel (see photo).

In some treadmills, the sensor is fitted parallel to the wheel while in others, it is fitted perpendicular to the wheel.

All you have to do is move the sensor a tiny bit to the front (or back) and restart the treadmill. If this did not work try to reposition again (see attached photo). Depending on how far the sensor shifted from its correct position, it might take a few tries before you get it right. You know you've got it right when the treadmill once again functions normally.

In 10% of the cases, the sensor wire might have either got disconnected or broken (usually happens if you're not too careful when removing or fitting the motor cover). If you are a DIY kind of person and have a soldering kit handy, then you will know what to do else, call the technician - shouldn't take more than 15 minutes to fix it.

Hope this helped.
