Honeywell Pressure Switch C6065F1241:2 For Cointra Domitop F24 E - Ref. 39806180
Honeywell C6065F1241:2 pressure switch with micro switch, also manufactured under the Yamatake brand and made in China. It is a pressure switch: it changes the state of an electrical contact (NC/C/NO scheme) according to the detected pressure difference, with a set point of 1.65 mbar and maximum switching at 6 mbar. It is replaced when it fails and causes the boiler to lock out.

How to check if ref. 39806180 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 39806180. 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 39806180 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, stops immediately, and displays a fault code.
Cause: The pressure switch does not close the contact properly and the control board does not allow the gas to flow.
Make sure the extractor is working properly, without any strange noises; a slow extractor can cause this fault.
- 02
The fault is intermittent: some days it starts without issues and others it locks up on the first attempt.
Cause: A pressure switch that is close to failing may operate under certain conditions and fail under others due to small pressure variations.
Keep a record of the days it fails and compare it with the wind or the outside temperature to rule out flue problems.
- 03
After cleaning or bleeding the boiler, it gets locked and does not start on its own.
Cause: A recent handling may have moved a tube or left the pressure switch in a position that the control board interprets as a fault.
Check that the pressure switch connection tubes are properly fitted after any intervention before replacing the part.
- 04
When measuring the pressure switch with the multimeter, the contact does not have continuity even though the boiler should ignite.
Cause: Without that electrical state change, the control board does not receive the necessary confirmation to open the gas.
Repeat the measurement with the extractor running, not just at rest, before confirming that there is a fault.
Fault codes for Cointra that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F8 | Insufficient water pressure in the heating system. | The water pressure switch (I39806180) does not close due to actual low pressure or mechanical/electrical failure; check pressure on the gauge (≥0.8–1.5 bar), continuity of the pressure switch and its wiring/terminal connections. |
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.
