JXi Troubleshooting Guide
NOTE: If Blower is on Go to Step 13
STEP 1 - Check Power at Dist. Brd. (make certain filter pump motor is on)
YES
STEP 8 - Check Power to High Limits
240 or 120 VAC between Black (C)
N O
wire and Red (B) wire on Power
YES
STEP 2 - Check Transformer
24 VAC between Red (2) wire and
Yellow (1) wire on Transformer?
YES
STEP 3 - Check Fuse
24 VAC between Red (3) wire on PIB
and Yellow (1) wire on Transformer?
Make certain filter pump is
on. Correct wiring
N O
If wired 240 VAC check voltage
between Black (E) wire and Blue (F)
wire. If wired 120 VAC check voltage
between Black (E) and White (D)
wires. If the correct voltage is
present, replace Transformer, if not
check Conversion Board position
N O
Locate and correct short circuit,
replace Fuse.
24 VAC between Black (8) wire on PIB
N O
and Yellow (1) wire on Transformer?
YES
STEP 9- Check High Limits
N O
24 VAC between Black (9) wire on PIB
and Yellow (1) wire on Transformer?
YES
STEP 10- Check Power to Ignition Control
N O
24 VAC between Black/Yellow(10) wire on
PIB and Yellow (1) wire on Transformer?
YES
STEP 11 - Check Power at Ignition Control
N O
Recheck power at Blue (7)
wire. If 24 VAC at Blue but
not Black, replace PIB.
Replace both High Limits.
Do a Temp. Rise Test.
Recheck power at Black (9)
wire. If 24 VACat Black, but
not Black/Yellow(10),
replace PIB.
YES
STEP 4- Check power to Water Press. Sw.
24 VAC between Purple (4) wire on PIB
N O
and Yellow (1) wire on Transformer?
Recheck at Red (3) wire, if
voltage is 24 VAC replace PIB.
24 VAC between Black/Yellow (11) at
W terminal of Ignition Control and
Yellow of Transformer? Correct problem with
Black/Yellow wire or its
connectors.
YES
STEP 5- Check Water Pressure Switch
N O
24 VAC between Gray (5) wire on PIB
and Yellow (1) wire on Transformer?
Back Pressure Test, if pressure is
higher than 2 PSI, replace Water
Pressure Switch, if less clean
filter, baskets or repair pressure
problem
YES
STEP 12 - Check Blower
Is Blower ON?
YES
N O
Check voltage between F2 terminal of
Ignition Control and ground (A0. Is voltage
105 VAC or higher?
YES
Check voltage between F1 terminal
YES
STEP 6 - Check power to Fusible Link
N O
24 VAC between Orange (6) wire on PIB
and Yellow (1) wire on Transformer?
YES
STEP 7 - Check Fusible Link
N O
24 VAC between Blue (7) wire on PIB
and Yellow (1) wire on Transformer?
Recheck voltage at Gray (5) wire,
if voltage is 24 VAC replace PIB.
Check Vent Limit and replace
failed part if necessary.
Correct incoming
power problem.
of Ignition Control and ground (A). Is
voltage 105 VAC or higher? If no,
replace Ignition Control, if yes check
voltage between Black (L) to Blower
PDB and white wire. Wired 120,
voltage range is 105 to 130, when
wired 240 range is 210 to 250. If
voltage is correct replace Blower. If
not check PDB and wires.
STEP 13 - Check Air Pressure Switch
YES
