How to check if ref. H035004339 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 H035004339. 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 extractor H035004339 resolves.
The extractor evacuates the combustion gases with forced draft. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler tries to ignite, the fan starts, and after a few seconds it stops and locks out.
Cause: The extractor does not reach the necessary revolutions for the control to validate the smoke evacuation, and the boiler shuts down for safety.
Before changing it, check if the turbine spins freely by hand with the boiler unplugged: if it is stiff or rubbing, confirm that the extractor is failing.
- 02
A new buzzing or chirping sound is heard when the boiler is running, louder than before.
Cause: The bearing of the extractor motor wears out over time and starts to rub, producing that characteristic noise.
Listen to see if the noise changes when you carefully hold the casing of the extractor: if it remains the same, the problem is the bearing and not a loose screw.
- 03
The boiler display shows a flue gas or draft fault.
Cause: The control detects that the fan is not spinning as expected and locks the boiler to prevent poor gas evacuation.
Check the exhaust duct to the outside (terminal, elbows, grille) for any obstruction that may prevent the fan from functioning before considering it faulty.
- 04
The extractor does not make any noise when the boiler is turned on, as if it is not receiving power.
Cause: The extractor motor may be burned out or not receiving electrical power.
Measure with a multimeter if power is reaching the connector of the fan before replacing it; if there is no power, the issue may be in the installation, not in the part.
Fault codes for Renova that this spare part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F2 | Safety lack of draft / aspiration or flue gas evacuation fault. | If the extractor motor H0350 does not start or rotates insufficiently, it does not create the depression and the air pressure switch does not switch; the boiler locks with F2. Check voltage to the fan, free rotation, depression in venturi/pressure switch tubes, and closure of the pressure switch during the start-up attempt. |
| F.32 | Fan fault: speed out of tolerance or fan blocked. | The extractor motor H0350 may fail (lock, seized bearings) or not deliver a tachometer signal; the electronics detect RPM out of range and generate F.32. Check the fan connector and power supply, Hall/tachometer signal, mechanical rotation, and absence of obstructions in air/smoke. |
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.
