3.20 110 VOLT OPTION RECEPTACLE TROUBLESHOOTING GUIDE
NOTE
Unplug all items from wall receptacle. Visually inspect contacts for any damage or foreign objects. Visually
check indicator light on the face of the receptacle. If indicator is unlit, Ground Fault Circuit Interrupter (GFCI)
has tripped. Pressing the reset button returns GFCI to normal operation (indicator should light). If reset but-
ton does not reset 110 VAC, see below troubleshooting.
When measuring 110 VAC at any point, use only neutral (white) side of power line as a reference point. Do
not use digital ground as a reference point.
PROBLEM/SYMPTOM
SOLUTION(S)
No power at 110 VAC duplex receptacle (GFCI). A. Using a voltmeter, measure across contacts. If
110 VAC is not present, check fuse FH1. Replace
receptacle and/or fuse as needed.
B. If fuse is O.K. and voltage is not present, re-
move receptacle and inspect connections. Re-
place cable assembly (p/n 3000–320–842) (see
pages 214 & 215 for cable location).
C. If 110 VAC is not present at litter CPU board at
connector P1, check power junction board (p/n
3000–300–961) at connector P1, pin 1 for 110
VAC (see page 199 for board location). If voltage
is not present, check fuse F2. Replace fuse, if
necessary. If fuse is O.K., and 110 VAC is not
present at connector P1, check connector J1, pin
2 for 110 VAC input from power cord. If 110 VAC
is present at connector J1, but not at connector
P1, replace power junction board .
D. If problem still exists, use a voltmeter to check
litter CPU board (p/n 3000–300–941) for 110 VAC
at connector P1, pin 2 (neutral) and pin 3 (hot). If
110 VAC voltage is present at connector P1, but
not at connector J1, pin 1 (neutral) and pin 2 (hot),
replace litter CPU (see page 115).
