SOURCE: Precor EFX 546 elliptcal shuts off

Your problem is most likely due to the magnetic sensor on the right side of the unit under the plastic housing.
The right pedal arm, has a magnet emeded in the on the inboard side of the arm. When the arm comes around and passes this sensor at the bottom of the unit, a pulse is generated and sent to the computer.
The mangetic sensor on the frame of the unit, may need to be adjusted to a closer proximity with the pedal arm magnet. Assure the arm does not strike the magnetic sensor however.
It's also possible the sensor has come loose and fallen into the base of the unit.

My precor efx 546 makes noise like a squeaking in left pedal it seems I tried to tighten pedal but I the whole bolt and screw turn together and the other pedal makes no noise

This squeak is normally caused by a bad bearing in the wheel. In order to provide you with the correct wheel, I will need your serial number. The following link will take you to our Precor EFX 546 page.

Precor efx 546 shuts off when I need to reverse direction during a workout also, the sliding is not smooth (very difficult to push the pedals on an easy level)

Procedure 6.4 - Troubleshooting the Generator
The generator performs three functions in the EFX. First, by controlling the amount of electrical
load applied to the generator, the user's pedalling resistance is controlled. Second, the generator
is used to charge the EFX's internal battery. Lastly, one of the generators six phase output
windings is monitored to determine when the unit is in use and when it is idle. This system also
determines the stride rate by determining the operating speed (output frequency) of the
monitored generator winding.
Because this is a self powered unit, it will either be necessary to either equip the unit with the
optional external power supply or have an assistant pedal on the unit while voltage
measurements are being taken. Because of the danger of working on the unit while it is in motion
using the optional external power supply is strongly recommended.
1. Perform the generator resistance test per Procedure 5.1. If any of the resistance
measurements are significantly high or significantly low, replace the generator.
2. The following voltage reading must be taken while the unit is in motion. Extreme care must
be taken to keep meter leads, hands, etc. clear of all moving parts. Using an AC voltmeter,
measure the voltage between 1 & 3, 2 & 3, 5 & 7 and 6 & 7 on J1 of the lower PCA. All AC
voltage readings will vary depending on the unit's stride rate at the time the measurement is
taken. At a stride rate of 100 strides per minute, all three voltage readings will be
approximately 100 VAC -110 VAC.
3. If any of the six readings in step 2 are significantly low, replace the generator.

There is a clicking sound periodically coming from the right pedal while I use the machine (Precor 546i). I tried tightening the bolts but the clicking persists. Any thought would be greatly appreciated....

It sounds like it could be a faulty bearing in one of your wheels, a worn ramp or a combination of the two. The following link will take you to our Precor page. Please reference your model and serial number. This will allow you access to the correct parts and manuals for your machine.

My 546i is telling me to pedal fast after I hit Quick Start or manually start a program. It's obviously not working. I just put a new battery in it too.

This problem maybe coming for n the generator it performs 3 function 1. controls electrical load / resistance to pedals 2. Charging system for the battery 3. Monitors unit when in use (stride) or when it is idle.
To test unit: Remove cover disconnect red battery lead. then use a multi-meter set function to ohms set range that can read 50 ohms. then disconnect generator lead from circuit board. M3=brown , M4= blue, M5= violet, with the meter read between Brown and blue, blue and violet , brown and violet, each of these read should be between 26 and 27 ohms. If any of the reading s are high or low replace generator
