No power on my precor c964i control board
Starting at the outlet, follow power into the machine. If you are getting power past the circuit breaker and in to the power board, chances are your lower board is toast. The only solution is to replace the item with a new or known good used board. The following links will take you to a video on how to use a multimeter to verify power.

Precor Error LS, Speed Sensor Signal Missing
Probable Cause
1. Intermittent or open connection of the speed sensor (reed switch) wiring.
2. Reed switch is defective or has intermittent connection.
3. Drive motor brushes are bad.
4. Lower PCA is bad.
Corrective Action
- Inspect the speed sensor (reed switch) wiring for damage or poor connection to the lower PCA. Replace damaged wiring or reset connection as necessary.
- Using an ohm meter, test the reed switch while rotating the drive pulley. The reed switch will close when the magnet passes in front of it.
- Inspect the drive motor brushes and replace if necessary.
- Test unit with a known good lower PCA. Replace lower PCA if necessary.

Adjusting Tension on a Treadmill Running Belt
It is necessary to properly tension a
treadmill beltwhen it is replaced. After time, a belt can stretch and may begin to slip. When this happens, it is necessary to adjust the tension of the running belt to stop it from slipping. Manufacturers of treadmills generally agree on one of three procedures for
how to tension a treadmill running belt.
- Adjust for no slippage of thetreadmill walking belton the front roller (Often referred to as the "Stomp Test")
- This procedure works well for a previously installed belt that is now slipping.
- Underside of belt should be free of any glazing/wax buildup.
- Rollers must also be free of wax buildup.
- Be sure belt tracking/centering is correct before proceeding.
- The most popular speed for this adjustment is 2mph to 3mph.
- Try to slow the belt by applying pressure with your foot against the belt movement while grasping the handrails. If the running belt slow, slips or stops (and the front roller does not) adjust BOTH adjustment bolts 1/4 turn clockwise. Test again and repeat adjustment if necessary.
- This procedure requires twobelt gauges or calipers
- This procedure works well when installing a new belt.
- This procedure requires you to stretch the belt. Depending on the manufacturer*, this varies between .4 and .6 percent. A dial on the gauge or caliper will indicate the amount of stretch. *Consult the owner/service manual for proper tension.
- If you are working on a previously tensioned belt you will need to release the tension before attaching the gauges or calipers.
- Gauges or Calipers unavailable
- Release the tension on the belt.
- Using a yard stick or tape measure, place two marks on the left and right edges of the belt and deck 36 inches apart (or 50 inches if you prefer).
- Adjust the left and right tensioning bolts until both sides measure 36 3/16 inches (or 50 1/4). This is equal to .5% of stretch.
- Test for proper tracking and tension, adjust if necessary.
