How to check if ref. 34V9000037 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 34V9000037. 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 that require diagnosis in the extractor 34V9000037
The extractor evacuates the combustion gases with forced draft. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The fan of the outdoor unit does not spin or has difficulty starting.
Cause: The motor is damaged or the bearing is seized and it cannot start.
With the equipment unplugged, turn the fan by hand; if it doesn't turn smoothly, check for ice, leaves, or dirt on the blades and the grille.
- 02
The outdoor unit makes noise or vibrates while operating.
Cause: The motor bearing is worn out and the propeller is rubbing or is misaligned.
Check that the impeller is properly secured to the shaft and does not rub against the casing before replacing the motor.
- 03
The aerothermal unit is showing a fault related to the fan and stops.
Cause: The control unit does not detect the rotation it expects from this motor and blocks the equipment for safety reasons.
Check the connector and the motor cable: a loose connection or a blown fuse can cause the same fault without the motor being faulty.
- 04
The equipment performs poorly, it heats or cools little.
Cause: If the fan spins slower than normal, the external heat exchanger does not receive the airflow it needs.
Visually compare the rotation speed with that of a similar unit in operation before considering that the motor is faulty.
Fault codes Saunier Duval that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| 37 | The fan's number of revolutions is too low. | A damaged, deformed, or obstructed fan blade reduces/prevents airflow, and the electronics detect insufficient rpm; visually inspect the blades and for any rubbing, manually spin it, and if necessary, remove the grille and nut to extract the fan blade and confirm that the fan is free. |
| 85 | Fan speed too low. | If the impeller is broken, loose, or unbalanced, the fan does not reach the target speed and the fault is triggered; check the condition and fastening of the impeller and confirm in the technical menu that the fan's rpm drop before the error. |
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.
