Top 20 Precor 546 Elliptical - Page 3 Questions & Answers


Hi There,

Precor uses a pair of Triacs to drive the lift up and down. These triacs live on the lower board but are driven by the upper console commands via a serial link between the upper and lower. Most precor lift issues we see are related to the lower board but with Precor it could be an upper board or the CPU Chip that resides on the lower board or a failed Triac. Good Luck

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..

This is normally caused by a stuck key on your keypad. To resolve this issue, you must replace the keypad.

The following link may help, but you will need your serial number to find the correct item.

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

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.

This sounds like you are dealing with a worn deck and belt. If you apply wax periodically, you can prolong the life of these components. Using your serial number, the link below will help you find the deck and belt needed for your model.

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.

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
  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.

If you really have a 'black dust' issue, your machine would be at least 7 years old - if it is less than 10 years, the parts would be under warranty, assuming you bought it new. One or both rollers and the walking belt would need to be replaced. You were advised to call Precor - did you? I am surprised the retailer did not offer any help - this seems like poor customer service.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/russell_1d1c35fa8a5a0be4
