How to check if ref. 05741000 is the part for your boiler

The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

1. Find the reference printed on the installed part and check whether it matches the catalogue reference 05741000. If it is not visible, do not identify the part from its shape alone.
2. Check the full boiler model on its data plate and look for it in the model associations on this page.
3. Compare the connections and physical body with the original part before installation.
4. If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.

Symptoms that require diagnosis on the PCB 05741000

The PCB controls the ignition, modulation, and safety features of the boiler. These are the typical symptoms and what to do:

Common symptoms and faults

• 01

  The boiler does not ignite and does not respond to the control.

  Cause: If the PCB does not send the start signal, the fan and the gas valve do not activate.

  Check the power supply of the boiler and the visible fuses before considering that the PCB is damaged.

• 02

  The controls and the temperature selector are not working.

  Cause: The PCB controls those signals; if it gets stuck, the panel does not respond even if it is in good condition.

  Cut the power for one minute and turn it back on: if the problem returns when turning it on, it could be the PCB.

• 03

  The boiler intermittently locks out without a clear pattern.

  Cause: Intermittent faults in the control electronics are often due to the relay module or the transformer when they start to fail.

  Note when the lock occurs (at startup, after several hours, with humidity) to determine if the problem is with the PCB.

These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.
