Non working bisquette heater

E-tronic · November 14, 2024, 08:26:44 AM

Hello again!

I have dissassembled the bisquette heater in order to measure both the elements and the temperature sensor.

The two elements – as the manual state 2x100 watts – has each 145 ohms so I guess they are connected in series and controlled by a relay as well as a SCR.

The temperature sensor reads about 238 ohms at 20 degrees Celsius ambient temperature. It seems on the low side, but can anyone share how many ohms there should be?

Is there by chance possible to access a service manual for this BS1019EC modell?

Thank you!

Perhaps more likely the European importer of Bradley Smokers will be able to help with this request, I am not aware of anyone having access to service manuals here on the forum?

Grakka, a UK based company are the European Importer so they could be a point of contact?

Presumably the unit is out of warranty.

Thank you for reply manxman!

Yes, this unit is out of warranty. I understand and as in most cases it can be quite difficult to get access to service manuals. I found some spare parts at bradleysmoker.se and will soon place an order and I will also send them an email about a service manual, but guess they will keep it "in house". The temperature sensor for the bisquette heater had really low ohm values, not knowing what they should be, so I guess the smoker might think that the plate is real ... real hot!

Yes many companies are reluctant to share service manuals, by maybe they would at least give you specific information such as this?

Did find this link offering individual tech support, US based but would no doubt have access to both US and European technical specs?

Thank you manxman!

I will drop them an email and ask for the values. I took the sensor out and when I had it on the bench I measured again and then it had turned to open circuit. I have som pictures that may help someone when they want to replace something in the bisquette heater, but I do not know how to upload them; I tried but failed. I also had a look on the controller board just in case I have to dig into that too in the future.

The BS1019 is now working since a few weeks back after I replaced the sensor for the bisquette heater. Thanks to manxman that directed me to Grakka I could order the spareparts I needed. Communicating with Grakka was to me a very pleasant experience and they were really helpful on all the questions I had.

Now, the only thing I am waiting for - which is a wish from a chef working at the upper secondary school who is also the owner of the BS1019 - is that some of the coming firmware updates includes an option to choose whether the user wants the oven to turn off or not when the temperature for the meat probe has reached its set temperature. It would be good if Bradley could make an exception and modify the firmware for those who wish so.

Glad it is working fine now, I have always found Grakka very helpful indeed.

Wouldn't hold your breath re such a firmware update, Bradley are not always the most proactive in such areas whatever the strength and merits of customer feedback.

Thank you manxman!

I wrote to Bradley support asking about the firmware option directly after I posted and I will of course get back with the outcome as all should do when a problem or whatever matter is solved - which is a good rule!

That certainly is a good rule, fingers crossed they will respond positively!
