Ravenheat Piezo Spark Generator Wh80/90 GEN150100

The Ravenheat GEN150100 is a piezo spark generator, the component that produces the high-voltage spark at the ignition electrode when the appliance calls for heat. It sits within the ignition circuit of Ravenheat gas appliances and is classed under ignitors and spark generators in the Ravenheat spares range. A working generator is what turns the gas and air mixture into a controlled light-up rather than a lockout.

• No spark at the ignition electrode when the appliance is called to fire, so the burner never lights.
• The appliance goes to lockout on every start attempt, with the fan and gas valve sequence running but no ignition.
• The audible click from the generator is weak, irregular, or absent when the demand for heat begins.
• Ignition is intermittent - the appliance lights on some attempts and fails on others.
• The generator body shows cracking, moisture ingress, or a damaged lead or terminal.

• Check the appliance GC number and model against the compatibility list, as the same appliance family can use different ignition components across build revisions.
• Confirm the part number on the existing generator matches GEN150100 or the alternative number 1842171 before ordering.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
