Life fitness recumbent bike problem

Likely the excitation to the alternator in this recumbent bike has dropped out, but there may be other causes.

You might start with this reference, which is how to access the various components:

Here is a link to the Life Fitness support page. You should be able to locate your manual there:

This problem can usually be resolved by replacing the overlay keypad.

tes the charger in another receptacle wall, if is ok , test the receptacle wall if is open, reset the circuit breaker .

Other is everything is o.k see if the board is fault or look for some wires loose, or disconnect.

Click here then click on LC95RS-0109-04 Parts list and the wire schematic is on the last page.

If this unit has not been used for that period of time then the 6v batt has died ans needs replacing call National Gym Parts @ 1-800-496-7278 to order part# LC001.5
HERE IS THE PROCEDURE TO REPLACE THE BATT:
Tilt the bike on its side, remove mounting screws securing the battery to the bracket. Remove the battery just enough to access and disconnect the black (neg) wire from the (-) terminal and the red (pos) wire form the (+) terminal. Replace battery and reverse procedure when installing battery

sounds like the keypad is not functioning since this is one of their older model I recommend call Life fitness and see if parts are available their # is 1-800-351-3737 they will probably will ask for a s#

Usually a faulty lower circuit board - remove and replace or call a local service tech.

You should check your battery-it must be putting out at least 6 volts to get the computer started up-depending on the era there will be a battery near the bottom frame-you will need to remove on of the side covers to reach it-

You have to start pedaling to get it to start up, some times you have to pedal pretty fast to get it to start up
