Code Description Duration Corrective Action
¢
E13
Combustion Fan
Speed Low. The
combustion air fan
speed less than
70% of expected.
60 Sec.
1. Check the combustion air fan wiring.
2. Replace the combustion air fan.
3. Replace the control board.
¢
E14
Combustion Fan
Speed High. The
combustion air fan
speed is more than
130% of expected.
60 Sec.
1. Check the combustion air fan wiring.
2. Replace the combustion air fan.
3. Replace the control board.
¢
LE0
Water level in tank
is low
Until
Corrected
1. Be sure all air is bled from system.
2. Inspect low level switch and wiring for
damage and repair as necessary.
¢
FLU
Blocked Vent
Pressure Switch
Open
Until
Corrected
1. Assure that the vent is not blocked
2. Check the blocked vent pressure
switch operation by applying a jumper.
(If the switch is not functioning properly,
replace it.)
¢
LOU
24 VAC low
Until
Corrected
1. Check line voltage. Must be between
100-128 VAC.
2. If available, connect PC and using
AdvantagePlus service software check
the 24 VAC supply display in the lower
left corner of the screen. The number
displayed here must be greater than
128 and should be greater than 250.
Use this as a troubleshooting guide as
you follow the steps below.
3. Remove 10 pin Molex connector from
customer connection board. If LOU
code clears, then the problem is with
external sensor wiring. Examine
external sensor wiring for shorts to
ground repairing as necessary. If LOU
code is still present and the boiler is so
equipped, disconnect high gas
pressure switch, then low gas pressure
switch, then UL 353 low water cutoff in
this order one at a time to see if LOU
code clears. Replace faulty part. Check
low voltage wire harness in boiler for
shorts to ground.
4. If LOU only occurs when burner tries to
light, check gas valve for excessive
current draw.
5. If LOU is present with the low voltage
harness disconnected from the 926
control board, replace the 926 control
board.
