Short or loose connection in
–
sensor rod.
Poor flame rectification or
–
contaminated sensor rod.

–
pilot assembly and gas valve.
Damaged pilot or sensor rod.
–
Pilot has been painted.

Verify all connections. Verify the connections from the
pilot assembly are tight; also verify these connection
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 the pilot
hood, the circuit is broken. A wrong orifice or too high
of an inlet pressure can cause the pilot to lift).
The sensor rod may need cleaning.
Verify that the wire harness is firmly connected to the
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 an emery cloth to remove any
contamination that may have accumulated on the
sensor rod. Verify continuity with multimeter with
ohms set at the lowest range. Check for shorted
wire or cracked insulator.
Using a piece of sandpaper or emery cloth, remove
the paint from the pilot hood, ignitor and flame sensor.
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.
Using a piece of sandpaper or emery cloth, remove
the paint from the pilot hood, ignitor and flame sensor.
Check that chimney is installed to building code.
Room is in negative pressure; increase fresh
air supply.
Check damper positioning.
Check for chimney blockage
