The answer James R sent has good information on adjusting the reed switch.

Be sure the magnet is still in the front roller.

If you have an ohm meter, disconnect the reed switch from the console and connect the meter to the 2 leads. Walk slowly on the treadmill and as the magnet passes the reed switch the meter should read 0-2 ohms resistance. When the magnet is not near the reed switch, the meter should read open circuit.

You might need to replace the reed switch.
