How to check if ref. 39841332 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.

1. Find the reference printed on the installed part and check whether it matches the catalogue reference 39841332. If it is not visible, do not identify the part from 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.

Symptoms and faults that the PCB 39841332 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 shows no signs of life: no display, no indicators, nothing at all.

  Cause: The PCB manages all the power supply and control of the boiler; if it fails, the unit will not start even if power is supplied.

  Check the fuse on the control board itself and verify that the main circuit breaker has not tripped before declaring the PCB as dead.

• 02

  It turns on, works for a while, and then suddenly locks up displaying a different fault code each time.

  Cause: When the PCB fails, the safety management becomes erratic and may trigger fault codes that are unrelated to each other.

  Note the codes that appear: if they change without a pattern and the reset does not solve anything, point to the PCB before a specific component.

• 03

  The thermostat in the house is calling for heat, but the boiler is not responding, as if it is not receiving the command.

  Cause: The PCB is the one that receives the signal from the thermostat or the communication bus and translates it into an ignition command.

  Check that the wiring of the thermostat and the bus connectors on the PCB are properly secured before replacing it.

• 04

  The boiler turns on and off by itself several times in a row without anyone touching anything.

  Cause: A relay on the PCB that fails intermittently can simulate on and off cycles without apparent reason.

  Check if the fault occurs more with the boiler cold or already hot: a thermal pattern points to the PCB and not to another element.

• 05

  The screen displays strange symbols or freezes without responding to any buttons.

  Cause: A fault in the microprocessor or in the memory of the PCB leaves the display without communication with the rest of the system.

  Perform a complete reset by cutting off the power for a couple of minutes and check if the behavior repeats the same when restarting.
