TROUBLE SHOOTING - INTERMITTENT PILOT
SYMPTOM
POSSIBLE CAUSE
CORRECTIVE ACTION
I. Pilot will not light after
repeated triggering of the
remote control – intermittent
pilot
A. No spark at electrode (weak or not heat source for pilot ignition)
1. Improper ignition
1. Align the electrode with 1/8” (3mm) gap to
pilot hood
2. Poor connections at starter and
ignition electrode
2. Reconnect if loose
3. Broken ceramic cover on
ignition electrode
3. Replace pilot assembly
4. Battery power low or dead
4. Replace batteries
B. No gas or low gas pressure
5. Gas line shut off(s) may not be
turned on
5. Turn on shut-off valves
6. Air in gas lines
6. Purge gas lines
7. Gas lines may not be
connected
7. Connect all gas lines
8. Low pressure may be caused
by bent line
8. Check for a kinked line
II. Pilot will not stay lit after
following the lighting
instructions
A. Thermocouple / Valve
1. Weak or improperly located pilot
flame
1. Adjust and clean pilot. The flame must
impinge on or engulf the thermocouple, as
shown in Figure 27.
2. Defective thermocouple
2. Replace thermocouple
3.Thermocouple not installed
properly
3. Make sure all wire connections at the gas
valve terminals are tight and the
thermocouple is fully inserted into the
mounting bracket
4. Open wire connection in pilot
circuit
4. Check wire continuity and connections in
the pilot circuit
5. Defective Valve
5. Check with your voltmeter.
B. Defective safety circuit
1. Loose or defective connections
1. Check continuity, tighten wiring or
connections, and repair
III. Main burner will not light
A. Valve / Switches
1. Valve control off
1. Turn to “ON” position
2. Blockage at the burner (line,
orifice, or ports)
2. Check and clean
3. Defective remote
3. Conduct a continuity test or jumper wire
test and replace if defective, check
batteries
