How to check if ref. R10028891 is the part for your boiler

What determines it is not the boiler model, but the reference printed on the part you already have installed.

1. Find the reference printed on the installed part and check whether it matches the catalogue reference R10028891. 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 and faults that the PCB R10028891 resolves.

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 generally works, but a specific component (fan, pump, or three-way valve) stops responding.

  Cause: The auxiliary PCB acts as an intermediary between the main PCB and certain components; if it fails, that component does not receive the command even though the rest functions properly.

  Measure with a multimeter if current is reaching that component at the moment it should be activated, before replacing the auxiliary.

• 02

  The boiler displays a fault code that the manual associates with an internal communication failure.

  Cause: The auxiliary PCB sends signals between the main PCB and the peripherals; a fault here can be interpreted as a communication failure.

  Check that the connector or flat cable between the two PCBs is properly seated before replacing the auxiliary.

• 03

  A specific mode of the boiler (for example, a mixed circuit) is not responding, although the rest is working fine.

  Cause: In these models, the auxiliary PCB manages additional functions; if it fails, only that function is lost and not the entire unit.

  Check if the fault always occurs in the same specific function before considering the auxiliary as faulty.

• 04

  When connecting the boiler, there is a burning smell or a component appears blackened in this area.

  Cause: A short circuit or a damaged electronic component in the auxiliary can visibly burn.

  With the boiler unplugged, look for burn marks or a localized smell on this PCB before deciding to replace it.
