PROBLEM POSSIBLE CAUSE CORRECTIVE ACTION
Lockout 88 – Outlet T Rise
limit
OR
Boiler making banging or
hissing sounds Insufficient water flow See Lockout 81.
Sensor disconnected
•
Verify that 2-position Molex connector on
wiring harness is securely attached to mating
connector on inlet sensor.
•
Inspect sensor wiring.
Hold 91– Inlet sensor fault
Faulty sensor Check resistance of sensor and compare to
thermistor resistance chart, see Table 16-2.
Sensor disconnected
•
Verify that 4-position Molex connector on
wiring harness is securely attached to mating
connector on outlet sensor.
•
Inspect sensor wiring.
Hold 92 – Outlet sensor fault
Faulty sensor Check resistance of sensor and compare to
thermistor resistance chart, see Table 16-2.
Sensor disconnected
•
Verify that 4-position Molex connector on
wiring harness is securely attached to mating
connector on stack sensor.
•
Inspect sensor wiring.
Hold 95 – Stack sensor fault
Faulty sensor Check resistance of sensor and compare to
thermistor resistance chart, see Table 16-2.
Insufficient gas line pressure Ensure the manual gas shutoff valve is open.
Check gas line pressure during ignition attempt.
Refer to Section 9.0 GAS VALVE AND
BURNER SETUP.
No 24VAC to Gas Valve Check the wiring harness for loose or interrupted
connections of the gas valve wiring. With an AC
voltmeter, measure the voltage from controller
terminals J5-2 to J4-10. There should be 24VAC
present during trial for ignition.
Faulty Gas Valve The gas valve emits an audible click when it
switches on or off. If the controller is providing
24VAC to the gas valve, and the wiring is intact,
it should be possible to detect if the valve is
responding.
Spark cable disconnected Ensure that the high voltage spark cable is
securely connected to the controller and the
igniter electrode. Check that the green ground
wire is securely attached to the ¼” quick connect
tab on the igniter electrode.
Faulty Spark Igniter/Circuit During trial for ignition check for arc on spark
electrode via the observation port located next to
the spark electrode in the burner door. If no spark
is observed – replace the igniter, spark cable then
controller.
Hold 110 – Ignition failure
occurred (failure to prove
flame after 3 ignition
attempts)
(Unit will not ignite)
Blocked Venting or Dirty Heat
Exchanger Check venting system and boiler for blockages
and dirt build-up – clean heat exchanger.
Flame rod disconnected Verify that the flame rod signal wire is securely
attached to the flame rod, which is located bottom
center of the burner door.
Blocked/Backed-up Condensate
Drain Remove condensate trap and flush.
Blocked Venting or Dirty Heat
Exchanger Check venting system and boiler for blockages
and dirt build-up – clean heat exchanger.
Hold 110 – Ignition failure
occurred (failure to prove
flame after 3 ignition
attempts)
(Unit lights and immediately
goes out)
Faulty Flame Rod/Circuit Replace flame rod then controller.
