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.

Burner flame is lost during run cycle, 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.

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.
