11.0 TROUBLE
SHOOTING
SYMPTOM
Main burner goes out;
pilot stays on.
Main burner goes out;
pilot goes out.
Pilot goes out when
the gas knob is
released.
The gas valve has an
interlock device
which will not allow
the pilot burner to be
lit until the thermo-
couple has cooled.
Allow approximately
60 seconds for the
thermocouple to
cool.
Pilot burning; no gas
to main burner; gas
knob is on ‘HI’; wall
switch / thermostat is
on.
Pilot will not light.
PROBLEM
TEST SOLUTION
Pilot flame is not large enough or
not engulfing the thermopile.
Thermopile shorting.
Remote wall switch wire is too long;
too much resistance in the system.
Faulty thermostat or switch.
Vent is blocked
Vent is re-circulating
Flexible vent has become
disconnected from appliance.
System is not correctly purged.
Out of propane gas.
Pilot flame is not large enough.
Pilot flame is not engulfing the
thermocouple
Thermocouple shorting / faulty.
Faulty valve.
Thermostat or switch is defective
Wall switch wiring is defective.
Main burner orifice is plugged.
Faulty valve.
No spark at pilot burner.
Out of propane gas.
Spark gap is incorrect.
No gas at the pilot burner.
- Turn up the pilot flame.
- Replace pilot assembly.
- Clean thermopile connection tot he valve. Reconnect.
- Replace thermopile / valve.
- Shorten wire to connect length or wire gauge.
- Replace.
- Check for vent blockage.
- Check joint seals and installation
- Re-attach to appliance.
- Cap was not replaced.
- Purge the gas line.
- Fill the tank.
- Turn up the pilot flame.
- Gently twist the pilot head to improve the flame pattern around
the thermocouple.
- Loosen and tighten thermocouple.
- Clean thermocouple and valve connection.
- Replace thermocouple.
- Replace valve.
- Replace.
- Connect a jumper wire across the wall switch terminals; if
main burner lights, replace switch / thermostat.
- Disconnect the switch wires & connect a jumper wire across
terminals 1 & 3; if the main burner lights, check the wires for
defects and/or replace wires.
- Remove stoppage in orifice.
- Replace.
- Check if pilot can be lit by a match.
- Check that the wire is connected to the push button igniter.
- Check if the push button igniter needs tightening.
- Replace the wire if the wire insulation is broken or frayed.
- Replace the electrode if the ceramic insulator is cracked or broken.
- Replace the push button ignitor
- Fill the tank.
- Spark gap should be 0.150” to 0.175” (5/32” to 11/64” approx.)
from the electrode tip and the pilot burner. To ensure proper
electrode location, tighten securing nut (finger tight plus 1/4 turn).
- Check that the manual valve is turned on.
- Check the pilot orifice for blockage.
- Replace the valve.
- Call the gas distributor.
