Ferroli PCB RPA 30 / RPA 30-2 Ref. 3T00437B
The Ferroli RPA 30 / RPA 30-2 PCB is the component that controls the ignition, burner modulation, pump, and safety features of your boiler. If it malfunctions, the boiler may not start, may lock out, or may operate erratically. This board is compatible with the Ferroli RPA 30 and RPA 30-2 models, among others. Replacement requires first confirming the fault of the part through technical diagnosis, even when operational issues persist, affecting the boiler's operation.

How to check if it is the part 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 —. If it is not visible, do not identify the part by 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
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 shows no signs: no lights, no display, as if it has no power.
Cause: The PCB is not supplying voltage to the installation because the main relay is not closing or it is not receiving power.
Measure with the multimeter that 230V is entering the PCB before declaring it dead; sometimes the problem comes from outside.
- 02
A fault code appears on the display and the boiler stops.
Cause: The electronics cut the cycle upon detecting an anomaly, although the source may be in a sensor that reports to the PCB and not in the PCB itself.
Note the exact code and consult the manual of the RPA 30 before changing the PCB, it may point to another component.
- 03
You request heat from the thermostat and the boiler does not respond.
Cause: The PCB is not reading or processing the demand signal coming from outside.
Do not force, hit, or bridge the component. Request a technical check according to the equipment manual before deciding on its replacement.
- 04
The boiler turns on and off by itself intermittently, without a fixed pattern.
Cause: A loose solder joint or a worn relay in the circuit causes intermittent power cuts.
With the boiler on, gently touch the PCB to see if the cut matches the rubbing; it is a sign of cold soldering.
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.
