TABLE 5-1: BOILER TROUBLESHOOTING PROCEDURES

FAULT

INDICATION

PROBABLE CAUSES

CORRECTIVE ACTION

STEPPER
MOTOR
FAILURE

Air/Fuel Valve out of calibration.

Air/Fuel Valve unplugged.

Loose wiring connection to the stepper motor.

Defective Air/Fuel Valve stepper motor.

Defective Power Supply Board or fuse.

Defective IGST Board.

Refer to C-More User Manual, OMM-0032 (GF-112) and perform the
Stepper Feedback Calibration procedure in Section 6, section 6.2.1.

Check that the Air/Fuel Valve is connected to the C-More Controller.

.Inspect for loose connections between the Air/Fuel Valve motor and
the wiring harness.

Replace stepper motor.

Check DS1 & DS2 LEDs on Power Supply Board. If they are not
steady ON, replace Power Supply Board.

Check “Heartbeat” LED DS1 and verify it is blinking ON & OFF every
second. If not, replace IGST Board.

SSOV FAULT
DURING
IGNITION

SSOV didn’t open

Check pilot assembly for carbon buildup.

Check scanners sensed pilot flame.

Check power through ignition relay.

Scanners close neutral side of relay coil.
