Hermann Renova Micra 2 24 E PCB Honeywell SM07407 Ref. 0020038693

The Honeywell Hermann Renova Micra 2 24 E PCB is the component that controls the ignition, burner modulation, pump, and safety features of your boiler. When this part fails, you will notice that the boiler does not start, locks out, or exhibits erratic behavior. It is compatible with models from the Hermann Habitat 2 and Micra 2 ranges, such as Habitat 2 23 E, Habitat 2 24 SE, Micra 2 23 E, and others. A technician must confirm through diagnosis whether it is necessary to replace it when there are operational faults that affect the normal operation of the boiler.

Guide

How to check if the reference 0020038693 is the part 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 0020038693. 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 0020038693

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 is not providing any heating or domestic hot water, it seems dead.

    Cause: The PCB is not distributing power to the outputs because its input stage is damaged.

    Check that power is reaching the boiler and that the differential has not tripped before replacing the PCB.

  • 02

    The display shows a fault and it does not go away even after resetting several times.

    Cause: The PCB detects an out-of-range reading from a sensor and locks for safety.

    First, check the sensor associated with that code (sensor, pressure switch, or flame detector) before replacing the entire PCB.

  • 03

    The remote control or the thermostat cannot get the boiler to start.

    Cause: The part of the PCB that receives and processes the command from the remote control is faulty.

    Test the thermostat on another boiler or change its batteries if it is wireless, to rule out that the fault is with the control itself.

  • 04

    The pump or the burner does not start even though there is a demand for heating.

    Cause: The output relay on the PCB that should activate them does not switch.

    Check if there is any noise or vibration in the pump when requesting heating; if it never reacts, point to 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.
