content: Wouldn't you know it, the one time I have a time sensitive project my soldering station malfunctions. The station itself is marked WEP 937d and from what I gather, it's a pretty good clone. After about a year though, it's giving me sensor errors (S - E on the screen) and incorrect temps. I need to get a replacement fast but with no where local I have to look online. There seem to be a bunch or styles available, all claiming to be compatible and besides that, how to I tell which ones are any good?I'm looking for either a genuine hakko element that will work, or a clone that is good quality has worked well for others. I don't want to have to do this again soon.In the picture you can see what the current one looks like. On the board it says YH936B-5.Any help is appreciated. I tried to search but I guess I don't have any idea what I'm looking for.

content: It's not heater, it's the sensor. Heater failure would show as 'H-E'. You need to dismantle the handle to access the sensor. Disconnect the sensor and check with continuity checker. If it tests positive then it quite possibly may be a wiring issue, which can be relatively easy fixed by simply running 2 new wires to the station. If the sensor itself is bad then you can simply hack in an external thermocouple placed in front of the nozzle. It's most likely K-type, but might as well be J-type.

content: Quote from: Bored@Work on February 09, 2014, 09:46:05 amOk, well what would you suggest? I have a hobby budget of $100 per month non compounding. Can you suggest a station around that price that would be better than what I have? I could be wrong about the way these things work but isn't the sensor in the heating element? If it would be cheaper I would rather buy a nee heater or the whole handle than replace the base unit if it is working fine. I honestly just don't know exactly what I need or how to locate the good quality clones vs the really cheap stuff.

content: That looks like a typical 936 heater element (and the board is marked 936, so there you go). There are two varieties of the ceramic element. The A1321 and the A1322, determining which you need can be accomplished by checking the resistance of the element or temperature sense wires.See this post of mine (and indeed the entire thread).https://www.eevblog.com/forum/reviews/genuine-vs-fake-hakko-936-ceramic-heater-a1321/msg236594/#msg236594

Since it's from Frys you know it's genuine as well. It was actually cheaper than done of the fakes.Sent from my EVO using Tapatalk
