Honeywell PCB Hermann Supermicra 24 SE Ref. 052002490

If your boiler does not start, locks out, or exhibits erratic behavior, a technical diagnosis must confirm if you need the Honeywell Hermann Supermicra 24 SE PCB. This board is the brain of the boiler, responsible for ignition, burner modulation, the pump, and safety features. Its failure can cause issues in the overall operation of the boiler. It is compatible with models such as Supermicra 24 SE, Supermicra 28 E, Supermicra 30 SE, and others from the Supermicra and Supermaster ranges. A technician must confirm through diagnosis if it needs to be replaced when these symptoms occur to restore normal operation.

Guide

How to check if the part number 052002490 is the correct one for your boiler.

The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

  1. Find the reference printed on the installed part and check whether it matches the catalogue reference 052002490. 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.
Diagnosis and fault codes

Symptoms that require diagnosis on the PCB 052002490

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, neither lights nor display.

    Cause: The PCB is responsible for powering and managing the components; if it fails, the boiler will not operate.

    Check if there is power to the boiler and inspect the fuse on the PCB before replacing it.

  • 02

    The display turns off and on by itself, or blinks for no apparent reason.

    Cause: An intermittent fault on the PCB can be caused by solder joints or components that fail with heat.

    Check if the fault occurs always with the boiler hot after a period of being on, or also when cold at startup.

  • 03

    The boiler locks up for no apparent reason and does not respond to the buttons or the remote control.

    Cause: If the microcontroller on the PCB stops responding, no command will have any effect.

    Cut the power for a couple of minutes and then restore it before changing it: this way you rule out a temporary hang-up.

  • 04

    The boiler ignites and then stops on its own without showing a clear fault.

    Cause: The PCB may be misinterpreting the signal from a sensor and stopping operation for safety reasons.

    Check that no other component, such as a sensor or a pressure switch, is giving an incorrect reading before blaming the PCB.

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.
