PCB Ineco CA 20 E N Ref. MU0849500
The control PCB Ineco CA 20 E N Ref. MU0849500 manages crucial functions such as ignition, burner modulation, the pump, and the safety features of the boiler. If it fails, you will notice that the boiler does not start, gets locked, or exhibits erratic behavior. This part is compatible with boilers from the CA, CE, FA, FE, and FEB ranges, including models like the CA 20 E N and the CE 20 E-1 N, among others. It is recommended to replace it when these symptoms are detected or if the boiler does not respond properly.

How to check if it 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 —. 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 and faults that the PCB (control board) 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 fan, no attempt to ignite.
Cause: The PCB manages the complete startup of the boiler; if it doesn't work, no component is activated.
Check that the boiler has a real power supply (plug, fuse, circuit breaker) and that the main thermostat is not turned off.
- 02
The display lights up and shows a fault code attributed to the PCB.
Cause: The electronics monitor their own safety features and display a fault code when they detect a problem in their control cycle.
Before replacing the part, check the code in the boiler manual: some 'PCB' codes may refer to a sensor or connected component.
- 03
The ignition is erratic: sometimes it lights properly, other times it cuts out or modulates strangely.
Cause: An intermittent behavior in the PCB is usually due to a loose connection or a component that fails only when it is hot.
Check all the connectors and cables that reach the PCB; a poorly connected terminal can produce the same symptom as a damaged board.
- 04
The boiler stops by itself in the middle of a heating or domestic hot water cycle without showing any visible error.
Cause: If the PCB loses an internal safety feature without displaying it, it cuts off the gas supply as a protective measure.
Before replacing, check that there are no power supply cuts in the home and if the boiler stops at the same time every day, which could indicate another cause.
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.
