TROUBLESHOOTING GUIDE - MILLIVOLT GAS CONTROL SYSTEM

Note: Before troubleshooting the gas control system, Ensure external gas shut off valve, located at gas supply inlet, (and wall switch, iff applicable), is

in the “ON” position. Important: Valve system troubleshooting should only be accomplished by a qualified service technician.

SYMPTOM

POSSIBLE CAUSES

CORRECTIVE ACTION

1. Spark igniter will not light pilot after

repeated triggering of igniter button.

WARNING: if the pilot will not light

after 1 minute of attempting, wait

for at least 5 minutes for gas to

clear before attempting again.

A. Defective igniter

(no spark at electrode).

Check for spark at electrode and pilot; if no spark and

electrode wire is properly connected, replace igniter.

B. Defective or misaligned electrode at pilot

(spark at electrode).

Using a match, light pilot. If pilot lights, turn off pilot

and trigger the igniter button again. If pilot lights, an

improper gas mixture caused the bad lighting and a

longer purge period is recommended. If pilot will not

light – check gap at electrode and pilot – should be 1/8"

to have a strong spark. If gap measures 1/8", replace

pilot (see Figures 17 & 18 on Page 12).

C. Gas supply pressure errant.

Check inlet gas pressure. It should be within the limits

as marked on the rating plate.

D. Pilot orifice plugged.

Clean or replace pilot orifice.

. Pilot will not stay lit after

carefully following the lighting

instructions.

A. Defective pilot generator

(thermocouple).

Check pilot flame, it must impinge on thermocouple

(see Figures 17 & 18 on Page 12). Clean and/or

adjust pilot for maximum flame impingement on

thermocouple. Ensure that the connection between

the valve and thermocouple are tight and secure.

. Pilot burning, no gas to burner, Valve

knob “ON,” and the (standard) burner

OFF/ON switch is “ON." Read impor-

tant note below.

IMPORTANT NOTE: If an optional

*remote switch is used for burner

operation, the standard burner

OFF/ON switch on appliance must

be in the "OFF" position.

*Optional remote switch kits - wall

switch or remote control.

A. Manual Reset Spill Switch has Tripped or is

defective.

Follow Manually Reset Spill Switch procedure on Page

6. Once the red reset button is fully depressed and

clicks in, check continuity with a multimeter between

switch terminal (Ohms). If it shows an open circuit,

replace switch.

B. Wall switch or wires defective.

Check wall switch and wires for proper connections.

Jumper wire across terminals at wall switch, if burner

comes on, replace defective wall switch. If okay, jumper

wires across wall switch wires at valve, if burner comes

on, wires are faulty or connections are bad.

C. Thermopile may not be generating suf-

ficient millivolts.

Check thermopile with millivolt meter. Take reading

at thermopile terminals of gas valve. Should read

325 millivolts minimum with optional wall switch

“OFF.” Replace faulty thermopile if reading is below

specified minimum.

D. Plugged burner orifice.

Check burner orifice for blockage and remove.

E. OFF/ON Switch & *Remote Switch are in

the "ON" position resulting in excessive

resistance.

When turning on the burner using a *remote switch,

ensure that the optional Off/On switch is in the "OFF"

position. If both switches are in the ON position, it

may result in excessive resistance (& millivolt drain-

age) and the burner may not come on.

4. Frequent pilot/burner outage prob-

lem.

A. Pilot flame may be too low or blowing (high)

causing the pilot/valve safety to drop out.

Clean and/or adjust pilot flame for maximum flame

impingement on thermocouple (see Figures 17 &

18 on Page 12).

TROUBLESHOOTING

SYMPTOM

POSSIBLE CAUSES

CORRECTIVE ACTION

1. Burner will not light.

A. Faulty Valve System.

See Below.

B. “OFF/ON” or wall switch defective.

Disconnect the two black wires from the wire nuts.

Test switch(s) for continuity with a multimeter. If

continuity is not indicated, switch(s) is defective and

must be replaced.

Note: Before replacing “OFF/ON” switch, Ensure to

check wiring for loose connections or broken wires

and repair as needed.

. Burners come “ON,” then turns “OFF.”

A. Burner orifice plugged.

Check main burner orifice(s) for blockage. Clean

or replace.

B. Obstructed vent system.

Check vent system for obstructions.
