Corrective Action
Verify 'S' (White) sense wire and 'I' (orange) ignitor wire
are connected to correct terminals on IFT-ECM.
Verify no loose connections or electrical shorts in wiring
from module to pilot assembly. Verify wire insulation is not
damaged. Verify wires are not grounding out to chassis,
pilot burner, or any other metal object. Replace any
damaged wires.
Verify spark gap is approximately 0.095" (2.41 mm) to
0.135" (3.43 mm).
Verify IFT-ECM slider switch is in ON or IFT-REM position.
Verify AC power available to junction box. Verify AC/DC
adaptor is plugged into junction box and ECM. Verify AC/
DC adaptor output voltage is between 5.7-6.3 Vdc. If
battery pack is used, check battery pack voltage is >4.2 V
(if not, replace batteries).
Verify system wiring configuration. Remove and reinstall
wiring harness that plugs into module. Check continuity
of wires in valve wiring harness. Replace any damaged
components.
Verify black ground wire in valve harness is connected to
metal chassis of fireplace.
Check if valve harness orange wire is connected to pilot
solenoid valve. Check pilot solenoid resistance, nominal
is 40 ohms. If open or shorted, replace valve. Check valve
harness wire continuity, if open replace 6-pin harness.
Replace ECM.
