I own the Schwinn 420 elliptical and I keep getting the E2 error on the console and the resistance will not work. I've checked the wires, what else could be causing the problem?
Clean the servo motor's potentiometer with 'tuner cleaner'. Remove the shroud on the 'passenger side' (it's a bit tricky, but not difficult). The potentiometer is a part of the black plastic servo motor assembly that adjusts the band of magnets (the magnets that create drag on the flywheel). The potentiometer measures the angle of the small pulley that tugs on the cable that moves the magnets. As often happens, potentiometers get dirty. In my case, the machine behaved intermittently, sometimes displaying the E2 error code. Cleaning the potentiometer solved the problem. Time will tell whether it's a permanent fix, but it certainly makes sense. If a potentiometer gives the 'brain' a bad signal, the brain won't know what to do. If you're not familiar with a potentiometer, it's a dial, like the volume control dial on your stereo. As you rotate the dial, it raises or lowers the electrical resistance, which the electronic circuitry can detect. In a stereo, it can control the volume. In the Elliptical, it tells the brain the location of the resistance magnets (how close to the flywheel, and thus how much resistance). It's a tight squeeze getting the can of tuner cleaner spray in there. Hope this helps.
SOURCE: The console does not work. E-2 shows up on the console.
We had this problem after assembly as well, it turned out to be a bent pin inside the connector to the flywheel housing (where the wires connect inside the lower part of the main mast). It was so bent that it never actually made contact with the connector.
We straightened the pin, carefully reconnected the wires, and everything worked just fine.
This says to us that the "E-2" error message means the console is missing at least one connection from the system. This could be caused by a bent pin, a torn/cut/frayed wire, etc -- anything that might make it lose signal.
So check the lower connection for bent pins, check the upper connection for bent pins, and check all along the wires for any kind of damage.
Hope this helps!

I think I am experiencing the same problem and have removed the shrouds. Are you experiencing a clicking sound while the unit is plugged in? All of this seems to deal with the servo motor. Don't be fooled by suggestions to replace the rpm sensor...this is NOT the problem. I am trying to find out what the initial setting for the servo motor and the tension cable should be. I found a site where you can order the servo motor, but it tells me that it could be months to receive this part. Sigh...
sincerely. God bless you
