5.3 TROUBLESHOOTING – NO POWER TO THE CONSOLE
1) SYMPTOM:
A. Turn on the power switch, but the console will not light up.
2) SOLUTION:
Please note the MCB in this model does NOT have an LED indicating the power is on. This means voltage

measurements must be taken to find the cause of a non-functioning console. Continue with each step below until
the problem is found.
A. Check power at the console. Measure power on pins 1 and 2 on the console cable where it connects to the
console. These are the same 2 wires labelled "12V and GND" on the console PCB as seen in the red circle below.
If there is approximately 12 VDC on pins 1 and 2, replace the console. If not, continue to step b.
B. Check the MCB is providing power to the console. Measure the pins in the yellow circle in the picture below. If
approximately 12 VDC is measured at these pins, replace the console cable.
C. Check that the MCB is receiving 120 VAC. Measure the black and white wires which connect to the MCB. If
there is approximately 120 VAC (+/- 15 VAC) on these wires, replace the MCB. As previously mentioned, this MCB
has no indicator LED to indicate the MCB is receiving power.
Check the outlet, power cord, breaker, switch, and internal wiring. If there was no AC voltage measured at
D.
the MCB in step 3, then there is a problem with the AC voltage getting to the MCB. Carefully check the building
breaker, electrical outlet, power cord, treadmill breaker, treadmill power switch, and treadmill internal wiring to
determine why AC voltage is not being supplied to the MCB. The technician must verify what is not functioning with
voltage and continuity checks before ordering any parts to avoid sending unnecessary parts.
