Air Pressure Switch Boiler Fagor FE24E1N / FE24EC1N - Ref. N49G006M4
Air pressure switch for Fagor boilers of the FE24E1N, FE24EC1N, ECOCOMPACFE20E, and FEB23E1B series. It monitors the air pressure in the combustion circuit and enables ignition only if the fan is functioning properly. The replacement requires first confirming the fault of the component through technical diagnosis, even when the boiler does not start or shows a ventilation/extraction error. Component code 605.99667, differential 140/89 Pa, part reference N49G006M4.

How to check if ref. N49G006M4 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 N49G006M4. 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 pressure switch N49G006M4
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 before the flame appears.
Cause: The pressure switch does not close the air contact, so the control board does not command the gas valve to open.
Check that the silicone tubes between the pressure switch and the fan are not bent, loose, or have accumulated condensation.
- 02
The display shows a warning of ventilation failure or lack of draft when starting.
Cause: This code is displayed when the control board does not receive the pressure signal it expects from the pressure switch, regardless of whether the fan is functioning properly.
Before changing the part, check the flue and the air intake for any external obstructions (nests, dirt, blocked terminal).
- 03
The fan is working properly, but the burner never ignites.
Cause: If the pressure switch has a stuck contact or a damaged diaphragm, it does not send the signal even if the actual depression is correct.
Listen to see if the fan maintains stable revolutions for several seconds before considering that the pressure switch is faulty.
- 04
The boiler occasionally locks out with the same fault, without a fixed pattern.
Cause: A worn contact of the pressure switch can work well sometimes and not at other times, causing intermittent faults.
Note if the blockage coincides with strong wind or heavy rain: this may indicate a problem in the flue section rather than with the pressure switch.
Fagor fault codes that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| F-2 | The air pressure switch does not detect air circulation (or is defective) and the boiler locks out. | The air pressure switch does not close due to lack of depression/draught or internal fault; check continuity of the contact when the fan starts and measure depression in the tubes, as well as inspect for obstructions in intake/exhaust. |
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.
