Check the spark igniter and spark

electrode and replace the units if

necessary.

Check for electrical shorting.

Check the spark gap, the gap should

be between 3 mm-4 mm. See

This appliance is ﬁtted with a "Heat

Sensor" positioned on the right hand

side of the heating unit.

Using a B.G.C. multimeter check for

continuity through the thermocouple

circuit (with the appliance cold). If a

fault is found it will be due to either a

faulty heat sensor or a faulty thermo-

couple.

To check the heat sensor remove it

from the cir- cuit and connect the two

leads together. Re-check the circuit, if

continuity is established then the heat

sensor is faulty and needs replacing. If

continuity is not established then the

thermo- couple is faulty.
