Guide

How to check if the ref. 87483004490 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 87483004490. 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.
Diagnosis and fault codes

Symptoms and faults that the PCB 87483004490 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 tries to ignite, but it fails to light the flame.

    Cause: The PCB is not sending the ignition signal to the other components at the right time.

    First, check if the gas is reaching and if the ignition electrode is clean before replacing the PCB.

  • 02

    Errors are appearing on the display that were not there before.

    Cause: The control electronics detect an internal fault or a communication issue with a sensor and display it on the screen.

    Note the exact code and check if it matches a known sensor before replacing the complete PCB.

  • 03

    The boiler does not respond to the remote control or the buttons on the control panel.

    Cause: The PCB is not processing the commands it receives from the panel or the remote control.

    Check that the flat cable or the connector of the panel is properly connected before requesting a new PCB.

  • 04

    It turns on, works for a while, and then turns off by itself, repeating the cycle.

    Cause: An intermittent fault in the control circuit causes lockouts that recover automatically.

    Note if the shutdown always occurs at the same moment in the cycle; this helps to differentiate between a fault in the PCB and a sensor.

Fault codes from Junkers that this part resolves.

CodeFaultDiagnosis and solution
F7The boiler does not ignite because the flame signal is incorrect.The ionization signal is incorrect. This may be due to a dirty or faulty photocell, affecting flame detection. If the PCB does not process this signal correctly, the boiler will not be able to ignite.

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.
