Air Pressure Switch Heatline / Demrad-Demirdöküm Ref. 3003200032
The Heatline / Demrad-Demirdöküm Air Pressure Switch Ref. 3003200032 is a component that checks the air pressure in the boiler and authorizes its operation. When it fails, the boiler does not start or gets locked, even if the actual pressure is correct, which may indicate a problem with the pressure switch. This model is compatible with various boilers, such as the Heatline Compact, Vizo, IG, System, Capriz, and Hydroline, as well as with the Demrad HK C, D, and B models, among others. It is recommended to replace the pressure switch when faults in air pressure are detected or if symptoms of locking in the boiler appear.

How to check if ref. 3003200032 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 3003200032. 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 pressure switch 3003200032 resolves.
The pressure switch controls the air or water pressure to authorize operation. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler tries to ignite, the fan starts, but it stops and locks out before the flame ignites.
Cause: The air pressure switch does not close the contact in time, and the control board interprets that there is not enough extraction, so it cuts off the gas cycle for safety.
Before changing it, check that the silicone tubes going from the pressure switch to the venturi/extractor are not disconnected, bent, or have accumulated water.
- 02
The flue fault appears and disappears on its own, especially on rainy or very windy days.
Cause: Condensate water can remain in the pressure intake pipes and alter the signal reaching the pressure switch, even if the fan is functioning properly.
Bleed the pipes by blowing carefully and check that they have a slope towards the extractor to prevent water accumulation.
- 03
The extractor spins normally, but the burner never starts.
Cause: The internal contact of the pressure switch may be dirty or oxidized and may not switch even if the generated pressure is correct.
With the extractor running, use a multimeter to check if the pressure switch closes the contact; if it doesn't, that's where the problem lies.
- 04
The blockage started right after cleaning or touching the flue gas outlet.
Cause: If the outdoor terminal is somewhat obstructed, the extractor does not create the necessary depression and the pressure switch, even if it is functioning properly, does not close.
Check the external outlet terminal and the duct section for any obstructions before discarding the part.
Fault codes for Airsol that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| Air pressure switch fault | Air pressure switch fault: the flue circuit depression/draught is not validated. | The Huba air pressure switch (ref. 3003200032) does not switch due to lack of differential pressure (flue/intake obstruction, dirty/deficient fan, obstructed pressure switch tube) or due to its own fault; check with a differential manometer and inspect the tube, fan, and flue outlet before replacing it. |
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.
