If the main flame does not light, check the orifice size for any blockage. Also, verify if there's 24 volts across control terminals P5-8 and P5-5. If there is no voltage, the control might be defective.
Why is my New Yorker CG40D Boiler circulator on but the boiler is off?
If the boiler is off but the circulator is on, check the boiler temperature. If the boiler water temperature is higher than the start temperature (default 140 F) and the circulator pre-purge time (default 2 minutes) has not expired, the boiler start will be delayed until the water temperature drops or the time expires.
What to do if my New Yorker CG40D Boiler temperature sensor fails?
If the temperature sensor fails, check that the sensor is securely attached to the control P7 connector and that the sensor wire is not damaged. If the problem continues, replace the sensor. If the problem still persists, replace the control.
What to do if the New Yorker CG40D Boiler damper failed to open?
If the damper failed to open, check for a loose connection between the control and vent damper, and inspect the damper harness. Also, check for any obstruction in the path of the damper. If the error does not clear, replace the control.
How to fix a New Yorker CG40D Boiler with a flame rod shorted to ground?
To fix a flame rod shorted to ground, check for excessive condensate, dry the pilot, and adjust the setpoint higher. Also, check for a loose or damaged ignition wire.
What to do if the New Yorker CG40D Boiler spark does not stop when pilot lights?
If the spark does not stop when the pilot lights, check for a loose connection in the ignition cable or ground wire. You should also check the continuity of the ignition cable.
What to do if New Yorker CG40D has flame present out of sequence?
If there is flame present out of sequence, check the gas valve for proper operation.
What to do if New Yorker CG40D is waiting for limit to open?
If the boiler is waiting for a limit to open, check the blocked vent switch and the flame rollout switch.
What to do if the New Yorker CG40D damper failed to open (STA 20)?
If the damper failed to open (STA 20), check if the control terminal 'P6 - 5' (yellow wire) is energized during status 'STA18' or 'STA 20'. Also, check for any obstruction in the path of the damper.
