SIT Gas Valve for Fagor Boiler CE 24E N SIT
The SIT gas valve for Fagor boiler CE 24E N SIT regulates and allows the flow of gas to the burner, acting under the commands of the control board. When it fails, the boiler may not ignite, experience flame lockouts, or modulate incorrectly. The user may notice issues such as fault code F1, which indicates a lockout due to ignition failure, or F10, which signals a fault in the control or closure of the valve. This valve is compatible with several models in the Fagor range, such as FE-20E, FE-24E, and FA-20E2N, among others. A technician must confirm through diagnosis whether replacement is necessary when these symptoms or fault codes are detected.

How to check if ref. MU0809100 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 MU0809100. 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 gas valve MU0809100
The gas valve regulates and modulates the gas flow to the burner. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler does not ignite or has intermittent ignition failure.
Cause: The gas valve does not allow gas to flow consistently when the control board requests it.
Measure the inlet gas pressure with a manometer before changing the gas valve.
- 02
The flame goes out while the boiler is operating normally.
Cause: The valve loses its opening or vibrates internally and stops supplying gas to the burner continuously.
Note when the flame goes out (immediately after ignition, at half power...) because that pattern helps to differentiate between the gas valve and the ionization electrode.
- 03
The gas supply to the burner seems irregular: the flame rises and falls without you touching anything.
Cause: The inlet filter of the valve may be clogged, or the valve is not maintaining a stable flow.
Check for dirt in the gas inlet filter of the valve before considering it faulty.
Fagor fault codes that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| F1 | Lockout due to ignition fault (flame not established). | The faulty/stuck gas valve may not open or modulate at startup, and insufficient gas may reach for ionization; check voltage in coils during the ignition attempt and pressure/flow in the ramp, ensuring the valve opens. |
| F6 | Flame detection with the burner at rest (parasitic flame). | If the gas valve does not close hermetically, it allows gas to pass and a residual flame persists; check the valve's closure/sealing when stopped and rule out a false ionization signal. |
| F10 | Fault in the control or closure of the gas valve. | Fault in the valve or its control circuit (coils/relays) prevents proper opening/closing; check coil continuity, control voltage from the PCB, and ensure the flame extinguishes when closure is commanded. |
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.
