TEST SOLUTION
Verify all connections. Verify the connections from the
pilot assembly are tight; also verify these connections are
not grounding out to any metal.
Verify the flame is engulfing the sensor rod. This will
increase the flame rectification. Verify correct pilot orifice is
installed and inlet gas specifications to manual. (Remember,
the flame carries the rectification current, not the gas. If the
flame lifts from pilot hood, the circuit is broken. A wrong
orifice or to high of an inlet pressure can cause the pilot
flame to lift.) The sensor rod may need cleaning.
Verify that the wire harness is firmly connected to module.
Verify that the ceramic insulator around the sensor rod is
not cracked, damaged, or loose. Verify the connection from
the sensor rod to the sensor wire.
Clean sensor rod with a fine emery cloth or synthetic
scrub pad to remove any contamination that may have
accumulated on the sensor rod. Verify continuity with
multimeter with ohms set at the lowest range.
Inspect all wires, ensure good tight connections. Verify
that all wiring is installed exactly as specified.
Inspect the wiring harness, and verify the harness is
tightly connected to the module. Verify that all wires are
connected in the right order. See "WIRING DIAGRAM"
section.
Check all seals.
Check if exhaust is re-entering through an open door or
window.
Clean the glass, see "CARE OF GLASS" section
DO NOT CLEAN GLASS WHEN HOT.
If deposits are not cleaned off regularly, the glass may
become permanently marked.
Tighten door clamps if applicable.
Restrict vent exit with restrictor plate. See
"RESTRICTING VENTS" section if applicable.
Remove blockage. In extreme conditions, ice buildup
may occur on the terminal and should be removed. To
minimize this from happening again, it is recommended
that the vent lengths that pass through unheated
spaces (attics, garages, crawl spaces) be wrapped
with an insulated mylar sleeve. Prevent sleeve from
sagging. Contact your local authorized dealer for more
information.
Check venting system parameters (seal, length, rise, etc.).
Check joint seals and installation.
