Chaffoteaux Niagara 23 FF / 28 FF Modulation PCB Ref. 60084516
The Chaffoteaux Niagara 23 FF / 28 FF Modulation PCB is the component that controls the ignition, burner modulation, pump, and safety features of the boiler. When it fails, the boiler may not start, lock out, or behave erratically, and fault code 32 may be displayed, indicating a communication defect between the main board and the display board. This board is compatible with the Niagara 23 FF and Niagara 28 FF models, among other boilers in the Niagara FF range. A technician must confirm through diagnosis whether it needs to be replaced when there are operational issues or recurring lockouts.

How to check if the part number 60084516 is the one for your boiler.
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 60084516. If it is not visible, do not identify the part from its shape alone.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms that require diagnosis on the PCB 60084516
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 flame seems to breathe: it rises and falls in intensity without you touching anything.
Cause: The PCB controls the flame modulation; if it fails, the boiler loses fine regulation.
Check that the burner and the gas filter are clean: an irregular flame due to dirt can easily be mistaken for a modulation fault.
- 02
The boiler heats in bursts, never on low flame.
Cause: Without modulation, the control can only operate at maximum power or off, with no intermediate levels.
Check if the ignition and shutdown noise is very frequent: it is the typical symptom of lost modulation, different from a simple starting fault.
- 03
The transformer on the PCB makes noise or feels hot to the touch.
Cause: The INECOSA transformer powers the control circuit; if it degrades, it affects the stability of the entire electronics.
With the boiler turned off and unplugged, visually check that the transformer has no signs of burning before replacing the complete PCB.
- 04
The boiler locks out after running for a while, not just when starting up.
Cause: A fault in the control chip can cause late lockouts due to loss of modulation signal, different from a start-up lockout.
Note how long it takes to block each time: if the time is always similar, it helps to differentiate a PCB fault from one related to the pressure switch or sensor.
Chaffoteaux fault codes that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| 32 | Communication fault between the main PCB and the display PCB. | The modulation PCB (main PCB, ref. 60084516) may stop communicating with the display due to an internal power supply fault or bus fault; check for stable 5 V and the communication signal at the display connector and the flat cable. If the wiring and voltages are correct and the error persists, the modulation PCB is defective (cross-test or replacement). |
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.
