5.0 TROUBLE SHOOTING
SYMPTOM
POSSIBLE CAUSE CORRECTIVE ACTION
A. No spark at electrode (weak or no heat source for pilot ignition)
1. Poor connections at starter
and ignition electrode
1. Reconnect if loose
2.
Broken ceramic cover on
ignition electrode
2. Replace pilot assembly
3. Defective piezo igniter
3. Replace piezo igniter
4. Poor grounding of piezo igniter
4. Tighten mounting nut and/or igniter
screws
B. No gas or low gas pressure
1. Turn on shut-off valves
2. Check propane tank; you may be out
of fuel
3. Purge gas lines
4. Connect all gas lines
5. Check for a kinked line
I. Pilot will not light after
repeated triggering of
the piezo ignition
button
1. Gas line shut off(s) may not be
turned on
2. No gas supply (LPG)
3. Air in gas lines
4. Gas lines may not be
connected
5. Low pressure may be caused
by bent line
6. Valve control knob not fully
depressed in “PILOT” position
6. Fully depress control knob
II. Pilot will not stay lit
after following the
lighting instructions
A. Thermocouple / Valve
1. Adjust and clean pilot. The flame
must impinge on or engulf the
thermocouple, as shown in Figure 22
2. Replace thermocouple
3. Make sure all wire connections at the
gas valve terminals are tight and the
thermocouple is fully inserted into the
mounting bracket
4. Check wire continuity and connections
in the pilot circuit
Weak or improperly located
pilot flame
Defective thermocouple
Thermocouple not installed
properly
Open wire connection in pilot
circuit
Defective Valve
5. Connect the millivolt meter probes to
the thermopile terminals on the gas
valve. Turn the valve to the “PILOT”
position, depress, and light. If the
meter reading is greater than 250
millivolts after 30 seconds, the
thermopile is good. If the pilot does
not stay lit, the valve is defective.
