Model: All Models
Error Description: Error 42, Lift Position Value Out of Range. Error 42 is displayed when the lift position reported by the lift position potentiometer is found to be outside its set limits.
If an Error 42 has occurred, it is important to know the physical position of the lift when the error occurred. It is possible the lift is physically out of range or jammed. In this case, the Error 42 is a secondary symptom and the issue should be approached as an Error 40. Possible Reason:

1. Bad or intermittent connection in the lift motor controller.
2. The lift motor requires calibration.
3. The lift motor potentiometer is bad.
4. The lower PCA to upper PCA cable is bad.
5. The lower PCA is bad.
6. The upper PCA is bad.

Recommended Action:

1. Intermittent connections can be difficult to locate. If the Error 42 condition is intermittent, a connection issue is probably the cause. This is definitely true if the Error 42 occurred while the lift was within its normal physical range. Inspect the lift potentiometer connector and repair connection if necessary. If the intermittent connection cannot be found or corrected, replace the lift motor. A lift calibration number of 0 or 255 indicates an open or shorted potentiometer connection. This means the problem could be anywhere between the lift motor and the upper PCA. Typically it can be identified and tracked using an ohmmeter.
2. Using the appropriate service manual for the unit being tested, refer to the lift calibration procedure. If the information in the service manual doesn't match the lift position/physical lift position of the unit, recalibrate the lift motor. [Something caused the lift motor to be out of calibration. Investigate for cause and correct. Simply recalibrating the lift motor will not solve the problem.]
3. If the lift calibration number is not 0 or 255 and does not change when the lift motor turns, replace the lift motor.
4. Check continuity of the interconnect cable or swap with a known good interconnect cable to verify if cable is bad.
5. Swap the lower PCA with a known good lower PCA to verify if the lower PCA is bad.
6. Swap the upper PCA with a know good upper PCA to verify if the upper PCA is bad.

It may be either the front shroud is installed incorrectly or broken, or the corkscrew for the incline motor is bent. If it is bent, it would need to be replaced.

Assuming the buttons are working, the numbers change on the display, and the incline works, it may be the lower circuit board or the generator. If it is a very old unit, it may be the electromagnet or the data cable that connects the two circuit boards.

please follow this steps and fix it. God bless youError 43 - Zero Switch not FoundDescriptionThe C944 and several versions of C96X used a lift position identification system that did notutilize a potentiometer.Instead, it utilized a switch that would be physically actuated by the lift when the lift was in thezero incline position. A revolution sensor counted lifted motor revolutions to determinesubsequent lift positions. In addition two limit switches where used to remove power from the liftmotor if the lift moved outside of it's normal range.When the unit was powered up the lift would start to hunt for the zero switch. It would first go up4% (maximum lowest physical position was -3%) if it did not find the zero switch or it hit the upperlimit switch, it would then go down until did find the zero switch. When the zero switch waslocated it would stop, the system would then know its physical position and be prepared tomonitor the revolution sensor. If during this power up procedure the zero switch was not found anerror 43 would be displayed.Possible Causes1. The lift position actuator does not physically operate the zero switch.2. The lower PCA is bad.3. The zero switch is bad.Possible Remedies1. There are several physical problems related to the lift platform mounting or the plate the zeroswitch is mounted on that can cause the actuator knob to miss the zero switch as it movespast. Repair the lift platform mounting, repair or replace the lift switch mounting plate asrequired.2. The lower PCA provides a 5 VDC power source for the zero switch. You should measure 5VDC across the zero switch when the zero switch is activated. If the reading is significantlylow, remove both wires from the zero switch and repeat the measurement across the wiresremoved from the zero switch. If the reading is still significantly low, verify the zero switchwiring. If the wiring is intact and correctly connected, replace the lower PCA.3. Move the lift to position where the zero is switch is not activated and remove power from thetreadmill. Remove both leads from the zero switch and measure the zero switch with anohmmeter. The zero switch should read very near 0 ohms. While measuring the zero switchwith the ohmmeter, activate the switch by hand, the reading should change to infinite (open).If either of the above readings are significantly incorrect, replace the zero switch.
