XINTEX S2 PROPANE SENSOR

[J. Nikitaridis]

For those of you who have a Xintex S2 propane sensor, if you haven't yet encountered a problem with the limited life of the sensor, you would also have been told by Xintex, as I was, that they no longer support that model, and they want you to buy the XINTEX S2A Fire Boy model, for $429. Well, be advised that since they will not replace or repair your sensor, all is not lost. My unit was sensing gasses, and the alarm was constant and the solenoid kept my propane shut, and could not use the stove, until I bypass the S2 and put 12v on the solenoid direct to be able to cook until I did this fix. I opened the sensor and exposed the electronic parts, and you will see a sensor round unit with 6 pins soldered into the small PC Board. if you google the part no. it comes up available and you can have it shipped all for a nominal fee, and then you need to un solder and solder the replacement, and you're good to go again, just like I was. So friends out there, I am happy to guide you if you need help, just email me.

Why not post your fix here?

could you post the part number?

[J. Nikitaridis]

Certainly. The sensor part # is FIGARO TGS-813

mine has been disabled for years because of this. I replaced it many times and just gave up and wired the solenoid to a switch.

junk.

Can anyone provide a review of the Trident propane control system? I have the choice between this and the Xintex S2a. Both feature two sensors.

If you have replaced the sensor a few times, if that's what you're saying, and it worked for some time? each time? Not sure. But I am inclined to think that perhaps the wiring on you terminal block might have been mixed up... The unit is pretty robust. I am going back to my sailboat today, and I will post a scan of the wiring diagram by tomorrow.

Thanks much, mine is on the edge and I'll order one for a back-up.

You're welcome. You will find that the unit is so stable that you will think it does not sensor non more. I will be posting a wiring diagram of the terminal block connections, in a day or two.

The downside of repairing this (or a CO or smoke detector) is that it is no longer certified but more importantly, not trustworthy.

Unlike repairing a starter or alternator where the boat might not start or charger the battery, you are gambling with your life here.

If that doesn't bother you, get out the soldering iron and have at it. Otherwise, consider a certified repaired or replacement unit.

The TG-813 sensor has been used in many brands of gas detectors,since,at least the'80s.
Very reliable,but it does contain a warming element.This element "burns out" after some yrs of service.Replace the element & ur back in business.
About the only other thing that kills this sensor is if it gets a dose of bilge water,from being mounted too low,sprayed,etc.
Some brands of detectors,such as the old Apelco,etc,mounted a tube socket on the pcb,& the TGS-813 sensor was plugged into socket-made it easy to change.

Sorry-4th line should read "replace the sensor"

Was glad to find this old thread. My sensor became more and more sensitive to the point that it was not useable. I ordered the Figaro sensor from ebay, it was about ten bucks. Soldered it in with my amateur-hour soldering ability and now it is functioning perfectly. Thanks!

I am in the same position as many others in that my sensor has packed up and i cannot get a replacement. When I pulled it apart I discovered that the whole circuit board was badly corroded. Bella Stars photo showed a very simple circuit board, mine has much more circuitry on it. Has anyone found a supplier for the board itself?

Those sensors are on ebay.
