What to do if the elco VECTRON G 1.40 starts, the ignition switches on, then fails?
- J

  If the Elco Burner starts, the ignition switches on, but then fails, here's what you can check: First, adjust the gas throughput. Inspect the condition and position of the ionization sensor relative to the earth, and check the connections of the ionization circuit. Adjust, clean, or replace the electrode(s). Connect or replace the cable(s). If those steps don't solve the issue, consider replacing the transformer, control unit, or compact gas unit. Also, check the cabling between the control unit and external components, and replace the valves if necessary.

  If the Elco Burner switches off during operation, it may be due to the air pressure switch contact opening or flame failure. Try adjusting or replacing the pressure switch. Also, check the ionization sensor circuit and consider checking or replacing the automatic combustion control unit.

  If the Elco Burner doesn't start after a thermostat shutdown and there's no malfunction indicated on the automatic combustion control unit, it could be due to a drop in supply voltage, a power failure, or a control unit malfunction. Check for voltage drops or power failures. If those aren't the cause, replace the control unit.

  If the Elco Burner blower starts but the burner itself doesn't, it could be that the air pressure switch contact isn't closing. Check the pressure transmitter for foreign bodies and inspect the wiring.

  If the Elco Burner blower starts but the burner does not, it might be due to flaring during pre-ventilation or pre-ignition. You should check the valve and the flame monitoring system.

What to do if elco Burner starts briefly then switches off?
- C
  Christopher BensonAug 20, 2025
  If the Elco Burner starts briefly when switched on, then switches off and the red LED lights up, it indicates that the control unit was deliberately shut down. Unlock the unit to resolve this.
