Error 40, No Lift Motion Detected
1. Blown lift fuse in lower PCA.
2. Lift motor is physically jammed and not able to move.
3. Bad lower PCA.
4. Bad lift capacitor.
5. Bad lift motor winding.
6. Bad interconnect cable between upper and lower PCA.
7. Bad upper PCA.
- Check the lift fuse from the lower PCA. Using an ohmmeter, the fuse
should measure 1 ohm or less. If the reading is significantly high,
replace the fuse. If the fuse is open, refer to steps 3 and 4 before
- Disconnect the lift motor from the ramp (elliptical) or lift
platform (treadmill). If the lift nut or lift tube is jammed against the
motor housing, turn the lift tube or lift nut away from the motor
housing. If the lift was jammed, refer to step 3 before continuing.
Calibrate the lift motor per the proper procedure for the unit being
serviced and reattach the lift motor to the ramp (elliptical) or lift
platform (treadmill). NOTICE: You must find and repair the cause for the
jammed lift. Only re-calibrating the lift motor will not solve the
- One of two modes can cause the lower PCA to fail. The lift switch
could fail in an operated condition. If this happens the lift will move
(either up or down) as soon as the unit powers up. The usual result is
that the lift will be physically jammed as explained above, and probably
also being cause for the lift fuse to blow. The lift switch could also
fail in an open condition. If this happened, the lift would not operate
in one direction. If either of these conditions occur the lower PCA
- Most units have the lift capacitor mounted inside the lift motor,
and others use external lift capacitors. This information applies to
units with the external lift capacitors. If the lift capacitor is
shorted the lift fuse blows. Check the capacitor for a short using an
ohm meter. Disconnect the capacitor from the lift motor and test. A good
capacitor reads in the millions of ohms. Replace the capacitor if the
reading is significantly low. Capacitor can also fail in the open
condition which would result with the lift motor trying to run but not
having normal power. Test the capacitor by measuring AC voltage across
it. A good capacitor will read AC peak voltage while an open capacitor
reads AC RMS voltage.
- When a lift motor winding is bad the lift will not operate in one or
both directions depending upon the exact fault in the motor. Check the
lift motor winding with an ohm meter. AC lift motors have a split
winding (3 wires) and DC lift motors will have a single winding. Both
windings must be checked on an AC lift motor. Normal winding readings
could vary anywhere between 1 and 60 ohms, depending on the lift motor
being tested. See the proper service manual for the motor being tested.
- Test unit with a known good interconnect cable. Replace the interconnect cable if necessary.
- Test unit with a known good upper PCA. Replace the lower PCA if necessary.
