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.

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.

The power switch on Precor treads is also a circuit breaker. If it trips when plugged in, you have a dead short in the machine.

INcline it all the way up and look underneath the ramp. Check where the ramp attaches to the main frame. If there are cracks in the bottom of the ramp, you need a new ramp, especially if you have a steel ramp as opposed to alumunum.

CHeck the fuses on the lower board. You may also want to unplug the eddy current magnet and speed sensor from the lower board and the heart rate sensor(if there is one) from the upper board to make sure they are not shorted out and not allowing the upper to light up.

Usually, yes. If it is old enough to plug in, there are two fuses in the power inlet/switch assembly. There is usually a fuse on the lower board for, at least, the elevation system.

Adjusting Tension on a Treadmill Running Belt It is necessary to properly tension a treadmill belt when 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.
  1. Adjust for no slippage of the treadmill walking belt on 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 two belt 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

Replacing a Treadmill Running Belt and Deck Following is a basic guideline of removing and replacing the running belt and deck on a treadmill. Due to different brands and designs of treadmills, the following should only be used as a guideline. If any of the information is not exact to the treadmill being serviced, refer to the service manual or call Sportsmith for further help. Tools Needed: Phillips Screwdriver, Set of Allen Wrenches, Set of Box End or Open Face Wrenches (Tools needed may vary depending on treadmill. )
  1. Switch the Power off on the unit.
  2. Next, unplug the unit from the wall.
  3. Remove the finger guard retaining screws and carefully remove the finger guards from the deck at each end of the rear roller.
  4. Loosen each rear roller bolt by 10 full turns. Then count the remaining turns necessary to remove the rear roller bolts. Remember to write down the number of turns needed to remove the bolts in each side for future reference.
  5. Carefully remove the rear roller from the unit. Clean any wax or debris buildup from the roller and place it aside.
  6. Raise the shroud and secure it with a bungee cord.
  7. Work the drive belt off the motor pulley by hand turning the flywheel while pushing the belt aside.
  8. Now remove the front roller retaining bolts.
  9. Carefully remove the front roller from the unit. Clean off any wax or debris buildup and set it aside.
  10. Loosen and remove the deck mounting hardware.
  11. Move the deck toward the left side of the frame to free the deck from the right side. The deck will move down once the frame has been cleared.
  12. Remove the deck and belt by raising the right side edge of the deck over the frame rail and sliding it to the right to remove.
  13. When installing a new belt or deck it is important to note that a new belt and deck surface should always be installed together. Failure to adhere to this guideline will severely shorten the life of the newly installed parts. Some decks can be used on both sides. However, be sure that each side is only used once. Be sure to install the belt in the proper direction on the unit.
  14. Install the belt and deck by first putting the belt on the deck, and then installing them from the right side as a unit.
  15. Be sure the deck is lined up with the frame and push the deck to the left side.
  16. Now carefully lower the right side of the deck to insert it into the frame rail and then push the deck to the right as far as possible.
  17. Re-install deck mounting hardware. (Check with mfr. for proper torque during install process.)
  18. Carefully place the front roller on the deck under the belt and push it forward into place, while placing the drive belt on the inside of the drive pulley.
  19. Replace the front roller bolts. (Check with mfr. for proper torque during install process.)
  20. Now spin the roller by hand while pushing the drive belt onto the pulley. Be sure to spin the roller several times to insure complete installation of the drive belt on the pulley.
  21. Install the rear roller into unit. Carefully start each bolt and turn one to two threads to ensure no cross-threading has occurred.
  22. Tighten each rear roller bolt the number of turns you kept earlier for reference.
  23. Now, Plug in and power on the unit.
  24. Carefully remove the bungee cord from the shroud and lower it back into place.
  25. Start the unit at a very slow speed and check for proper belt alignment. Remember to start at the slowest speed possible and be ready to stop the unit quickly if needed.
  26. If the belt is moving to right side of unit tighten the right roller bolt, If the belt is moving to the left side of the unit tighten the left roller bolt until the belt is tracking properly.
  27. Caution: make very small adjustments such as 1/4 turns and then watch the belt for several moments before making another adjustment.
  28. Once the belt is tracking properly walk on the unit at a slow speed and check for belt slippage on foot fall. If this is happening tighten each of the rear roller bolts equal turns until the slippage is no longer occurring. Caution: make very small adjustments such as ¼ turns and then watch the belt for several moments before making another adjustment.
  29. Now use the unit at a jogging speed to check for belt travel or slippage.
  30. If slippage still occurs make small equal adjustments (1/4 turns) to both sides of rear roller and re-test.
  31. Install the finger guards once you have enough clearance from the rear roller.
  32. Some manufacturers require wax or lube during the install process, please consult your owner's or service manual for further information regarding this.

There could be other possibilities causing the treadmill to stop but one of the most common issues is excessive wear on the belt/deck.

When a running belt has excessive wear, it creates a lot of friction which causes the drive motor to work harder. When the drive motor works harder it will start overheating. If the belt is not lubricated periodically, it will ruin the deck, the drive motor, and cause other electrical problems such as tripping the breaker [after a while, the circuit breaker on the treadmill will need to be replaced.

It is suggested to lubricate the belt every month. At this point, you may need to replace both your deck and your running belt
