9. No gas to burner. The gas valve should open at the same time as the
igniter sparks. If there is no gas to the burner when
this occurs check the solenoid coils for continuity.
Check that the gas pressure is present at the test
point when the spark is being generated.
Check that there is gas to the inlet of the gas control.
10. Appliance lights but goes Test the flame for correct ionisation signal. Connect a
into lockout. multimeter in series with the flame rod and set the
function to measure micro-amps. The module will go
into lockout if the flame current sensitivity is less than
0.5 micro-amps. The approximate signal strength on
high flame is about 10 micro-amps and on low
4 micro-amps. The signal strength will fluctuate but
should be greater than 1.5 micro-amps at all times.
Take precaution because the ionisation probe can
have a high negative voltage and can cause shock.
11. Fuse blowing. If the fuse continues to blow check the solenoid coils
for signs of them being shorted.
Check the fan and wiring for short circuit.
Connections
Terminals 5, 6 and 7 at the module 12 way connector are bridged.
Terminal 10 at the module 12 way connector is the active supply via the
red wire.
Terminal 11 at the module 12 way connector is the neutral supply via the
blue wire.
Terminal 12 at the module 12 way connector is the earth connection via
the green/yellow wire.
Terminal 12 at the module 2 way connector is the neutral connection via a
brown wire which is joined into the rectifier cable then into the 8 way
switch connector blue wire.
Terminal 14 is an active connection at the module 2 way connector via a
white wire into the 8 way switch connector. This is active only when the
flame is sensed.
