What it is

The Hamworthy 339007018 is a sequence control unit for Hamworthy gas boilers, supplied in the LFL1.335 SER.01 variant rated at 240V. It governs the boiler's start-up sequence, supervising the burner through pre-purge, ignition and flame proving before allowing normal running.

Signs this part needs replacing

  • Boiler goes to lockout during or immediately after the start-up sequence
  • Burner fails to reach ignition, or ignition is attempted without flame proving
  • Repeated lockouts that clear on reset but return on the next call for heat
  • No pre-purge, or fan and pump do not run despite a demand for heat
  • Intermittent or erratic firing behaviour traced back to the control

Before you order

  • Confirm the existing control carries the same LFL1.335 SER.01 marking and 240V rating
  • Check the boiler model against the manufacturer's parts list to confirm this part number applies
  • Sequence controls are safety-critical components — fitting should be carried out by a competent heating engineer
  • Isolate the electrical supply before removing the existing control
