Molex 0039012060 connector Mini-fit 6 pin

0039012060 Connector Mini-fit 6 pin MOLEX (catalogue article 728.640.903) is a plug or connector from the Molex brand, listed under Plugs and connectors. As a Mini-fit 6-pin type, it belongs to a series of connectors designed for low-voltage signal and mains supply wiring between the control board and components such as gas valves, fans, sensors, or actuators. Parts of this type are matched by pin count (6 pins), series (Mini-fit), and keying rather than by function. When replacing a connector, verify the pin count, pitch, and whether the housing is keyed to prevent misconnection. Conductor cross-section, insulation temperature class, and terminal type (crimp or IDC) must also match the original harness. Poor contact in any connector can mimic electrical faults—intermittent burner lockout, false flame signals, or erratic modulation—so connectors are routinely inspected during fault finding. Always check for corrosion, loose terminals, or damaged locking tabs before condemning other components.
