SOURCE: err22 showing.How can I start?

The speed sensor is a hall effect sensor that emits a pulse when a flywheel lobe passes between
its transmitter and receiver. The speed control circuit processes the pulse train emitted by the
speed sensor. The speed sensor signal is a real time representation of the operating speed of
the treadmill. The speed control circuit compares the real time speed (speed sensor output) with
the speed that it expects the treadmill to be operating at and acts accordingly to control treadmill
speed or initiate an error code sequence, if necessary. Typically, if a problem exists with the
speed sensor the drive motor will operate (perhaps only briefly) before a speed related error
occurs (errors 20-26).
1. Set the treadmill circuit breaker in the “on” position. Using a DC voltmeter, measure
the voltage between terminal 3 of J2 (green wire) and terminal 4 of J2 (black wire) on
the lower PCA. Slowly, rotate the drive motor flywheel. The voltage should read
approximately 5 Vdc when a flywheel lobe is between the speed sensor “legs” and
approximately 0.25 Vdc when a flywheel lobe is not between the speed sensor “legs”

2. If the voltages in step 1 are correct, go to step 5. If the voltage in step 1 is 0 Vdc or
significantly low when a flywheel lobe is between the speed sensor “legs, continue with step
3.
3. Measure the voltage between terminal 1 of J2 (red wire) and terminal 4 of J2 (black wire) on
the lower PCA. The voltage should read approximately 5 Vdc.

4. If the voltage is missing or significantly low, disconnect the speed sensor plug from the lower
PCA. Measure the voltage between pins 1 & 4 of the J2 plug on the lower PCA. If the
voltage is approximately 5 Vdc, replace the speed sensor. If the voltage is missing or
significantly low, replace the lower PCA.
5. At this point the speed sensor output is good, but a speed error occurs. There are two
potential causes for this condition. They are upper PCA or lower PCA. There are no good
means of troubleshooting these components other than substituting known good
components. Replace only one component at a time. If the component that you replaced
does not correct the problem, replace the original component. Try substituting the lower
PCA first then the upper PCA, if necessary.

When push quick start button, why does it display Erro 30 and doesn't run?


Hi There....This is a great message for ALL PRECOR 956/966 owners. This failure usually relates to a "communications" error between the upper and lower electronics. This particular failure is a direct result of a failed IFT drive module, or the lower drive "box" that is made by Advanced Drive Technology. The brains of this lower controller has failed and cannot "talk" to the upper board anymore due to several failed parts inside this box. You are lucky to have this failure arise over a fatal blow-out. Now replacements thru Precor or a distributor will be $550+ and are usually low stock items at places, but you can get repairs and exchanges of this Precor IFT drive by emailing gregATbuyfitnessrepairpartsDOTcom for much less than all other vendors. Currently these IFT drives are 380 exchange and 199 repair and turnaround is one day. Good Luck!

The belt on my Precor C966i treadmill is not running and the display is flashing an "Error 22" message - what's the problem?


Error 22 means the drive motor is diconnected. you will hear the fan and other parts make noise but check the red and black anderson connection between the main circuit board and motor.

Philips lcd 37pf9431d/37


finally got some help from customer service ----
the code flashing one then two red lights is for an upgrade of the software ---- you can go to their website and download a current fix to that problem onto a thumb drive----
\the power problem is caused by a bad power board--- you can replace them for any where from 130-330.00
dont need a service tech - take off cover and easy to replace---can find part on parts store.com for philips televisions --- used is about 130 and new about 330 -- used is a refurbished unit and works just as good as the new one

sounds like either a powerboard or control board is sending erratic voltage or no voltage to the table motor and possibly the light.

TV turns on for a split second then back to standyby


i think your capacitor is blown, do a google search for insignia, lcd, capacitor...
you can buy another one for about $2 but its a pain to install, you can also instead buy a new powerboard for about $80, its an east install and you wont blow more capacitors

Hi Sootycat

Ok , most of the time this would be the Fan.Powerboard that is faulty then and unfortunatelly it would be better to replace the part rather than having it repaired.

Repaired Powerboards normally give the same problem a couple of months down the line.
