Sidsa Cointra M20F PCB Ref. COIN8069
Control PCB for the Cointra M20F boiler, manufactured by Sidsa, with the logo printed on the circuit itself. The transformer it uses has the reference 0004820 R4913 and operates from 230V to 15V. The commercial reference COIN8069 is not printed on the board. Replacement requires first confirming the fault of the part through technical diagnosis, even when the boiler's control module fails.

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, neither display nor indicator light, despite having power in the house.
Cause: If the transformer on the PCB stops supplying the current that powers the control, all the electronics shut down.
Measure with a multimeter if there is output current in the transformer before replacing the complete PCB.
- 02
It locks up with a fault code that does not match any real problem detected.
Cause: The control module interprets the signals from all the sensors; if its electronics fail, it generates warnings that do not match reality.
Reset and note if the fault code changes between attempts: if it is not always the same, suspect the PCB before the indicated component.
- 03
The panel does not respond to any button presses, as if it were frozen.
Cause: The microcontroller on the PCB processes user commands; if it freezes, it stops responding.
Disconnect the boiler from the power supply for 2-3 minutes and try again before declaring the PCB faulty.
- 04
The pump or the fan does not start even though the relay can be heard activating.
Cause: The control module sends the command but does not deliver output current to the component.
Check with the multimeter if there is current at the output connector at the moment it should be activated.
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.
