How to check if ref. MU0837600 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 MU0837600. 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 MU0837600 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 does not ignite and the display shows an error related to the air circuit.
Cause: The pressure switch does not send the correct pressure signal to allow the gas to flow.
Before changing the part, check that the tube connecting the fan to the pressure switch is not crushed, bent, or disconnected.
- 02
The fan fault or blockage appears repeatedly, even after resetting the boiler several times.
Cause: The pressure switch does not reliably close the contact on each attempt, causing the lockout to repeat.
Check the intake air filter, if the boiler has one, because a dirty filter also reduces the pressure that reaches the pressure switch.
- 03
The boiler hangs for a few seconds after the ignition attempt and then locks out.
Cause: The pressure switch takes a long time to close the contact or does so weakly, and the control board runs out of the waiting time and locks for safety.
Check for any moisture or water accumulation inside the silicone tubes, especially if the boiler is a condensing type.
- 04
The fan is working normally, but the remote control or the display continues to show the air fault.
Cause: The pressure switch does not inform the PCB that the pressure is correct, even though the fan is working well.
If possible, measure continuity in the pressure switch with a multimeter when the fan is running to confirm if the contact closes.
Fault codes for Fagor that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 2 | The air pressure switch does not detect air circulation or is faulty. | If the pressure switch does not close due to lack of depression/draught (obstruction in chimney/intake or fan) or due to internal failure, the PCB locks with "2". Check the continuity of the pressure switch when applying depression to the tubes, inspect tubes/venturi, and ensure the fan generates sufficient differential. |
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.
