Honeywell Hermann Micra Condens 26 Display Electronic Module Ref. HE052004901
The Honeywell Hermann Micra Condens 26 Electronic Display Module is a control PCB that manages functions such as ignition, burner modulation, the pump, and the safety features of the boiler. If this part fails, you may notice that the boiler does not start, locks out, or exhibits erratic behavior. It is compatible with several models, such as the Hermann Habitat 2 23 E, Habitat 2 24 SE, Micra 2 23 E, Micra 2 24 SE, Micra 2 30 SE, and some from the Tiberis range, among others. It is advisable to replace it when the boiler shows starting issues or irregular operation.

How to check if the reference HE052004901 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 HE052004901. 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 HE052004901 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 screen stays black and does not turn on, although the rest of the boiler starts up normally.
Cause: The display module is responsible for generating the image on the display; if it fails, there is no visualization even if the power PCB is functioning properly.
Make sure that the flat connector between this module and the power PCB is properly seated, with no bent pins, before replacing it.
- 02
The boiler is working, but neither the temperature nor any fault code is visible.
Cause: This module receives data from the main PCB and translates it on the screen.
Cut the power supply for a couple of minutes and then restore the power to see if the display retrieves the information before replacing the part.
- 03
The buttons on the front panel do not respond when pressed.
Cause: In this model, the controls are integrated into the screen module itself, so an internal fault also affects the touch response.
Check for any moisture or oxidation on the button frame before discarding the module.
- 04
The screen flickers or turns off by itself intermittently.
Cause: A poor connection in the module's connection or an internal fault in its electronics causes intermittent image cuts.
Check that the wiring and the connector are not loose or showing signs of overheating before replacing the part.
Fault codes Hermann that this part solves
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F.27 | The boiler turns off for no apparent reason. | The boiler has shut down due to a flame detection error. This may be caused by moisture in the electronics or a fault in the gas valve. If you notice that the boiler turns off for no apparent reason, the PCB may be affected. |
| F.29 | The boiler does not keep the flame lit. | A flame loss has been detected. This may be due to an interruption in the gas supply or recirculation of combustion gases. If you notice that the boiler does not keep the flame lit, the PCB could be the 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.
