Corrective Action
Verify "S" wire (white) for sensor and "I" wire (orange) for ignitor are
connected to correct terminals on module and pilot assembly.
Verify no loose connections or electrical shorts in wiring from mod-
ule to pilot assembly. Verify connections underneath pilot assembly
are tight; also verify igniter and flame sense wires are not grounding
out to metal chassis, pilot burner, pilot enclosure, mesh screen if
present, or any other metal object.
Verify gap of igniter to right side of pilot hood. The gap should be
approximately .17 in. or 1/8 in. (3 mm).
Verify that transformer is installed and plugged into module. Check
voltage of transformer at connection to module. Acceptable read-
ings of a good transformer are between 6.4 and 6.6 volts dC. Bat-
tery power supply voltage must be at least 4 volts. If less than 4
volts, replace batteries.
Remove and reinstall the wiring harness that plugs into module.
Verify there is a tight fit. Verify pilot assembly wiring to module. Re-
move and verify continuity of each wire in wiring harness. Replace
any damaged components.
Verify that 110-120 VAC power is "ON" to junction box.
Verify black ground wire from module wire harness is grounded to
metal chassis of appliance.
Verify that incoming gas line ball valve is "open". Verify that inlet
pressure reading is within acceptable limits.
Verify gap of igniter to right side of pilot hood. The gap should be
approximately .17 in. or 1/8 in. (3 mm).
Verify module is securely grounded to metal chassis of appliance.
Verify that 1.5 to 1.8 VdC is supplied to pilot solenoid from module.
If below 1.5 volts, replace module. If 1.5 volts or greater, replace
valve.
