Procedure 6.5 - Upper Display does not Illuminate
Note:
Serial code SB is equipped with two fuses in the A.C. power module and two fuses on the lower
PCA. Serial code AMPF is equipped with two fuses in the A.C. power module and one fuse on
the lower PCA.
Serial code SB has two LED’s, one green and one red on the lower PCA. Serial code AMPF has
one green LED on the lower PCA.
1.
Set the on/off switch in the “off” position, unplug the line cord from the wall outlet.
2.
Remove the F3 system fuse from the lower PCA, serial code SB, only. (See Diagram 6.5)
3.
Remove the fuses from the power entry module. (See Procedure 7.29)
4.
Check all of the fuses with an ohmmeter. They should read approximately 1
Ω
or less.
Replace any fuse that reads significantly high.
5.
Replace the fuses in the power input module, do not replace the F3 system fuse at this time
(serial code SB), at this time.
6.
With the line cord still unplugged from the wall outlet, set the on/off switch in the “on”
position. Check between the power terminals of the line cord with an ohmmeter. The
ohmmeter should read infinity (serial code SB) or 1 to 1.5 megohm (serial code AMPF).
7.
If the reading for serial code SB is good skip to step 11, if the reading is significantly low,
continue with the next step. If the reading for serial code AMPF is good, skip to step 13, if
the reading is significantly low, continue with the next step
8.
If the reading in step 6 is significantly low, check the wiring between the lower PCA and the
on/off switch, between the on/off switch and the input module. Replace any cut or nicked
wiring.
9.
Check the line cord for nicked or cut wiring. Replace the line cord if necessary.
10. For serial code SB only, replace the F3 (2 amp) fuse in the lower PCA, if applicable, perform
the resistance measurement in step 6. The reading should be approximately 1.1 to 1.5
megohm
.
11. If the reading in step 10 (serial code SB) or step 6 (serial code AMPF) is significantly low,
replace the lower PCA
12. If you have performed all of the above tests and are unable to resolve the problem, contact
Precor customer support.
13. Plug the line cord into the wall outlet and set the on/off switch in the “on” position.
