Hi Emily, The safety switch... If that's the plastic part with the steel plate inside it that attaches to the console and when you remove it the treadmill won't operate then try cutting the top off a can and using that until you find the safety switch...Good Luck.....CHEERS..

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. Video about Multimeter Testing

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

1. Inspect the speed sensor (reed switch) wiring for damage or poor connection to the lower PCA. Replace damaged wiring or reset connection as necessary.
2. 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.
3. Inspect the drive motor brushes and replace if necessary.
4. 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 atreadmill 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 forhow to tension a treadmill running belt.

1. Adjust for no slippage of thetreadmill walking belton the front roller (Often referred to as the "Stomp Test")
   1. This procedure works well for a previously installed belt that is now slipping.
   2. Underside of belt should be free of any glazing/wax buildup.
   3. Rollers must also be free of wax buildup.
   4. Be sure belt tracking/centering is correct before proceeding.
   5. The most popular speed for this adjustment is 2mph to 3mph.
   6. 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.
2. This procedure requires twobelt gauges or calipers
   1. This procedure works well when installing a new belt.
   2. 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.
   3. If you are working on a previously tensioned belt you will need to release the tension before attaching the gauges or calipers.
3. Gauges or Calipers unavailable
   1. Release the tension on the belt.
   2. 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).
   3. 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.
   4. Test for proper tracking and tension, adjust if necessary.

How to Tension Treadmill Walking Belt that Slips

On C846 version 1 units, set the on/off switch in the "on" position. It will be necessary to start pedaling for the bicycle to "power up". For any other units, we recommend checking for any loose, crimped, or visually bad wires. Make sure the speed sensor on your bike is working. You can run a quick test by using a magnet to swipe in front of the sensor to see if it is sending signal to your console.

Precor Error 05, Key Depressed at Power Up Probable Cause 1. A key is permanently depressed on the display. 2. An interface chip (IC) has failed in the upper PCA's keypad. 3. Liquid (cleaning solution or sweat) may be on the surface of a touch sensitive display. Corrective Action

1. Disconnect the keypad cable from the upper PCA. Reset power to the machine. If the Error 05 is eliminated, the keypad is the cause and should be replaced.
2. Disconnect the keypad cable from the upper PCA. Reset power to the machine. If the Error 05 still appears, the upper PCA* is the cause and should be replaced. *Upper PCA's most commonly do not come with software. Remove the software (chip) from the existing upper PCA prior to replacement and install into the new upper PCA.
3. Wipe away all liquid from the touch sensitive display. Reset power to the unit. If the Error 05 is eliminated, the liquid was the cause.

Error Code List for Precor Fitness Equipment

Precor Error Code 21 Error Code: 21 Manufacturer: Precor Model: All Models Error Description: Error 21, Too many Consecutive Power Requests- The error 21 observes a treadmill's power bit reading when the treadmill was operating at speeds above 1 mph. Power bits indicate the relative time that the motor controller drive circuit is turned on. Power bits is an indication of the amount of power the load is demanding from the motor controller. Error 21 indicates that at a speed greater than 1 mph, an excessive amount of power is being demanded from the motor controller. Possible Reason:

1. A badly worn deck and/or running belt can cause the error to appear when the unit is in use.
2. Badly worn drive motor brushes may not be making proper contact with the drive motor commutator causing the error to occur when the unit is in use. The unit may also slow down or become sluggish when the load or speed is increased.
3. A jumper may be required on the lower PCA if installed into a 120 VAC (Version 2) treadmill.
4. A leaky or shorted drive motor filter capacitor (on units equipped with SCR motor controller) could increase the current demand enough to cause the error.
5. A leaky or shorted drive motor inductor (on units equipped with SCR motor controller) could increase the current demand enough to cause the error.
6. The high power demand is caused by a shorted or de-magnetized drive motor.

Recommended Action:

1. Determine the amount of AC input current being drawn by the unit under no load and loaded conditions using a clamp on AC ammeter. The current displayed can be used to determine the condition of the deck and/or running belt. These same readings should be taken on a like unit, in good operating condition with a know good deck and running belt. The readings from the unit in good operationg condition can be used as the benchmark. Compare readings and replace* the deck and/or running belt if necessary. *Some units have a reversible deck. Be sure if the deck is being flipped or replaced, a new belt is installed on the new deck surface.*
2. Inspect and repalce both drive motor brushes if necessary.
3. Inspect the lower PCA (if unit is 120 VAC/ Version 2) for jumper. If jumper is not installed, error typically appears between 7 mph & 8 mph. Install jumper if necessary. CAUTION - DO NOT install jumper if unit is 240 VAC. Installing the jumper on a 240 VAC unit will casue the lower PCA to fail.
4. Measure the AC input current without a load using a clamp on AC ammeter. Electrically isolate the filter capacitor from the drive motor circuit. The drive motor leads need be kept intact so the drive motor will operate with the filter capacitor removed from the circuit. Re-measure the no load AC input. If the AC input current is significantly lower, replace the filter capacitor.
5. Measure the AC input current without a load using a clamp on AC ammeter. Electrically isolate the inductor from the drive motor circuit. The drive motor leads need be kept intact so the drive motor will operate with the inductor removed from the circuit. Re-measure the no load AC input. If the AC input current is significantly lower, replace the inductor.
6. Swap the existing drive motor with a known good drive motor.
