PCB Display Biasi Parva Low NOx M95 24CM BD Ref. BI1975103
When opening the hot water tap or turning on the heating, the Biasi Parva Low NOx M95 24CM BD PCB (control board) is responsible for controlling the ignition, the modulation of the burner, the pump, and the safety features of the boiler. If this part fails, it is possible that the boiler will not start, become blocked, or operate erratically. It is installed in Biasi M95 boilers, among others, ensuring compatibility with models such as the M95.24 CM/BD. It should be replaced when these malfunction symptoms are present.

How to check if ref. BI1975103 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.
- Find the reference printed on the installed part and check whether it matches the catalogue reference BI1975103. 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 and faults that the PCB BI1975103 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 screen stays completely black and does not turn on.
Cause: There is a problem with the power supply or the backlighting of the screen, without affecting the rest of the electronics.
Force the boiler to operate (for example, from the thermostat) and check if it heats normally; if the burner ignites, the fault is in the display and not in the power PCB.
- 02
The boiler is working and heating, but nothing appears on the display.
Cause: This indicates that the fault is in the display module, while the control logic is still functioning.
Check the connector or flat cable that connects the screen to the motherboard; a poor connection can cause the same symptom without the screen actually being damaged.
- 03
The screen glass or casing is broken or cracked.
Cause: A mechanical shock or stress on the frame can damage the LCD, even if the rest of the control panel is intact.
Before ordering the part, confirm that the breakage is only aesthetic and has not affected the buttons or the connector, to avoid buying more than necessary.
- 04
The screen turns on but is partially visible, with lines or dark areas.
Cause: This is usually a partial fault of the LCD, different from a general power issue.
Gently press the screen frame while observing if the image changes; if it does, the issue might be with the contact rather than the part itself.
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.
