| Isolate Mains Power to appliance as per TOPs P4 |
Set Multimeter to DC Volts 
On/Off Switch ON
Disconnect user control from the main PCB
Disconnect user control from the main PCB
| WARNING! - Mains voltage is expected during test follow TOPs P4 live testing procedure |
Measurement:
Measure the DC voltage between the two outer pins on the rear of the display PCB connector (screw side up).
Ensure a good contact is made and that the red probe is on the pin on the right and the black probe is on the pin on the left
Expect 26.5 vdc or greater.
Note:
The voltage may fluctuate slightly but should remain above 26.5 vdc.
