Maximum Number of
Retries Detected
•
Burner is either not lighting or not staying lit during ignition cycle.
•
Check inlet gas pressure for minimum pressure on rating label.
•
Can you hear sparking to the burner?
•
Check high voltage cable connections.
•
Check inlet gas pressure to the gas valve making sure the pressure is within
the limits specified on the rating label.
•
Check gas valve wire harness for broken wires or shorts.
•
Check outlet gas pressure.
•
If 24 volts is present to the terminals at the gas valve, replace gas valve.
•
Check for voltage output to the blue gas valve wires on the control board pins.
•
If during the ignition trial period, there is no voltage present at the control
board pin terminals for the blue wires leading to the gas valve, then replace
the control board.
•
Replace spark rod if insulator is damaged or rod is loose.
•
Check to make sure combustion blower is operating when thermostat calls for
heat.
•
If blower is not running check for 120 volts to blower harness and then at
blower pin connections.
•
Replace control, wire harness, or blower if defective.
•
Check to make sure vent terminals are clear of debris or snow and ice.
•
Make sure the condensate drain flows freely.

Maximum Number of
Ignition Recycles
Detected
•
Burner flame is lost during run cycle, and then re-established on ignition cycle.
Check inlet gas pressure.
•
Is gas pressure dropping below the minimum operating pressure on the rating
label after the gas valve opens?
•
Is the gas pipe size to the water heater adequate?
•
Check the condition of the burner.
•
Clean or replace as needed.
•
Check the burner flame and observe the microamp output on the run cycle.
•
Replace burner if clogged with dirt and debris.
•
Replace spark rod or flame sensor if damaged.
•
Check to make sure vent terminals are clear of debris or snow and ice.
•
Make sure the condensate drain flows freely.
64
Electronics Failure
•
Replace control board.
65
High Water
Temperature (Over
200°F
(93°C)
)
•
Water temperature in tank has exceeded 200°F
(93°C)
.
•
Check tank sensor.
•
Make sure sensor is fully inserted into the well (clip on sensor wire secures
sensor in place).
•
Check sensor reading.
•
If not within specifications, replace sensor.
•
If sensor and wire harnesses check O.K., replace control board.
