Guide

How to check if ref. 0020184123 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 0020184123. If it is not visible, do not identify the part by 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 that require diagnosis on the PCB 0020184123

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 shows no attempt to start.

    Cause: The PCB does not complete the startup because its control stage has failed.

    Check that the 230V input reaches the PCB before replacing it.

  • 02

    The sensors and controls stop working, as if they are not receiving control power.

    Cause: The PCB converts the 230V input into 24V to power sensors and controls, and if it fails, both are lost.

    Measure with the multimeter if there is 24V at the output of the PCB before declaring the fault as certain.

  • 03

    The boiler locks out without any other component (gas, flame, pressure) justifying it.

    Cause: A fault in the control electronics causes the system to lock even though the rest of the installation is in good condition.

    First, rule out the pressure switch, the NTC sensor, and the flame detector: if all measurements are correct, the problem points to the PCB.

Fault codes Saunier Duval that require diagnosis

CodeFaultTechnical checks
F63Main PCB faultThe EEPROM/electronics of the main board is damaged or corrupted, causing the equipment to lock. Check the board voltages, connections, and if the issue persists, replace/reprogram the PCB 0020184123.

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.

Frequently Asked Questions

Frequently asked questions about the PCB 0020184123

Is this V-Group PCB original from Saunier Duval?
V-Group is silkscreened on the board. That marking alone does not establish its commercial origin or prove that it is an original Saunier Duval spare part.
What is the operating voltage of the PCB of the Themafast Nox F30?
Markings of 230 V and 24 V are visible, but the photograph does not establish which terminals are inputs or outputs. Consult the wiring diagram for the exact version; do not infer connections from these numbers.
When should this PCB be replaced in a Nox F25-A LPG?
It should be checked when the original PCB fails and stops controlling the boiler. The replacement requires a technical diagnosis.
