926884-1 Connector Mini-fit round Fan MOLEX Catalogue article 728.514.950. Manufacturer codes 926884-1, 24307.45002, 728.514.950. Brand: Molex. This article is a connector belonging to the Mini-fit round Fan series from Molex. Parts of this type carry low-voltage control signals and mains supply between the burner control board and system components such as the fan, gas valve, ignition transformer, or sensors. Connectors are matched by pin count, pitch, and keying rather than by function; the same physical connector may serve different signals depending on the wiring harness. When selecting a replacement, match the connector series, pin count, conductor cross-section, insulation temperature class, and terminal type. The wiring length and terminal style (crimp, solder, or insulation displacement) must also be verified against the original. Poor contact in any connector can reproduce almost any electrical fault symptom — intermittent flame loss, false lockout, or erratic modulation — so connectors are a routine suspect during fault finding. Always inspect the terminal condition and locking mechanism before replacing.
