Ariston Microgenus 23 MFFI PCB Control Ref. 65101732
The Ariston Microgenus 23 MFFI Control PCB Ref. 65101732 is a component that manages the ignition, burner modulation, pump, and safety features of the boiler. When it fails, the boiler may not start, become locked, or exhibit erratic behavior, which can manifest with fault codes A97, A98, or A99. This PCB is compatible with several models, including the Microgenus 27 MFFI, Microgenus 23 MFFI, and Microgenus Plus 28 MFFI, among others. It is recommended to replace it upon noticing these symptoms or faults in operation.

How to check if ref. 65101732 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 65101732. 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 65101732 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 does not ignite and shows no signs of operation, neither fan nor spark.
Cause: The control board initiates the ignition sequence; if it is not active, no other component will function.
Check if there is power to the boiler and verify that the fuse on the PCB is not blown.
- 02
An error code appears and the boiler locks up when trying to ignite.
Cause: The PCB manages the safety sequence and locks the equipment if it does not receive the correct signals for flame or pressure.
Note the exact code that appears and compare it with the manual before assuming that the fault is in the PCB.
- 03
The fan or the pump remain continuously on even when there is no demand.
Cause: A fault in the outputs of the PCB can cause a relay to stick and keep the component continuously active.
Disconnect the connector from that output and check if the component stops; if it doesn't stop, the fault is not with the PCB.
- 04
The boiler runs for a few minutes and then shuts off by itself repeatedly.
Cause: An intermittent fault in the control electronics cuts off the gas supply as a safety measure.
Check if the cut always occurs at the same point in the cycle, as this helps to differentiate between a PCB fault and a sensor fault.
Fault codes for Ariston that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| A97 | Shutdown due to a fault in the operating logic. | Internal fault of the CMP3‑MCU PCB (monitoring/firmware) causing the board itself to lock the equipment. Check voltages 230 V/5–12 V on the board, grounds, and connectors, reseat the EEPROM key; if it persists, replace the board. |
| A98 | Shutdown due to a fault in the operating logic. | Electronic control/monitoring anomaly in the main PCB (CMP3‑MCU): logical or reading inconsistencies cause the PCB to stop the boiler. Check power supplies, connectors, and EEPROM key; if not corrected, the PCB is defective and must be replaced. |
| A99 | Shutdown due to a fault in the operating logic. | Logic/electronic monitoring error managed by the CMP3‑MCU board; the boiler goes into lockout due to an internal PCB fault. Check voltages and connections of the board and EEPROM; if it persists after checks, replace the board. |
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.
