Main PCB Hermann Micra Condens 26 Ref. 052005326
The Main PCB Hermann Micra Condens 26 is the component responsible for controlling the ignition, burner modulation, pump, and safety features of the boiler. When it fails, the boiler may not start, become locked, or exhibit erratic behavior, which can result in fault codes such as F.61, F.62, F.63, F.64, or F.65. This board is compatible with models from the Micra Condens range, as well as some boilers from the Micra 2 and Renova Habitat ranges. It is recommended to replace it when these symptoms or fault codes are identified.

How to check if the reference 052005326 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 052005326. 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 052005326 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
Nothing turns on: neither the display, nor the fan, nor the pump, the boiler seems dead.
Cause: The PCB distributes power to all components; if its circuit is damaged, no current reaches any of them.
Check the internal fuse of the PCB and the power plug: a fault there gives the same symptom.
- 02
A fault code appears on the screen that reappears every time you try to reset.
Cause: The control system of the PCB detects an anomaly and locks the ignition in safety mode.
Note the exact code and check its meaning: it may point to a different component than the PCB.
- 03
The pump or the fan does not start even though the boiler requests heat.
Cause: The PCB activates those elements through relays; if one is stuck or burned out, the component does not receive power.
Check if the fan or the pump spins when forced manually, to rule out that the fault is in them and not in the PCB.
- 04
The hot water comes in bursts, turning on and off by itself during the shower.
Cause: A fault in the electronics managing the modulation causes irregular burner shutdowns.
Check the circuit pressure and the water flow: low pressure gives the same symptom without the PCB failing.
Fault codes for Renova that this spare part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F.61 | Fuel control valve error | The PCB controls the gas valve; a fault in the driver/relay or management on the PCB causes incorrect control. Check the harness and coils; if there are correct voltages/signals and the valve is fine, the PCB is the cause. |
| F.62 | Error, delayed disconnection of the fuel control valve | The relay/triac on the control board may become 'stuck' or delayed, keeping the valve energized. If the wiring, electrode, and valve are OK, the fault lies in the PCB. |
| F.63 | Fault: EEPROM | Corruption/defect of the integrated memory in the PCB. After reset and parameter check, if it reappears, the solution is to replace the PCB. |
| F.64 | Fault, electronics/temperature sensor | The A/D reading of the NTC is performed by the PCB; if the NTC and wiring measure correctly, the fault is in the measurement circuit of the PCB. Confirm by measuring the 5V/3.3V reference and continuity. |
| F.65 | Electronic temperature fault | The PCB's own electronics detect overheating (internal sensor or affected circuit). If there are no external heat causes and it persists, the PCB is damaged. |
| F.67 | Fault: electronics/flame | Ionisation signal not plausible due to detection circuit fault in the PCB. If the electrode, grounding, and wiring are correct, the PCB is responsible. |
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.
