    Thyristor?

    I think this is a thyristor. If that's what "th" means on the board. Numbers are B1
    15.
    It has continuity between the two legs. I tested in diode mode and it has .18V forward and reverse. Is this good or bad?

      Re: Thyristor?

      That is Thermistor, Thyristor is the semiconductor device such as SCR, or bidirectional triode thyristor (or TRIAC)
      Just Google Thermistor.

              Can not find Model/Value of Thermistor.
              by nmbb
              Machine: Autoclave.
              Brand/Model: SANYO MLS-3780
              Manual: (Sorry search option not working on this PDF)



              Hello guys, this autoclave running with 2 thermistors already connected TH1 and TH3(on CN1,CN2 sockets). One for the water temperture and second one for chamber temperature. But there is another emtpy socket for optional third thermistor CN2 wich is for TH2 for object temperature. I wanna add the third thermistor TH2 to CN2 socket. But i can't figure what model/brand/value i need to use. In manual document, there is no info about TH1 and TH3 model number...

              FCL30A015 diode reverse biased shows 35 Ohm, 0.05V forward. Is it gone?
              by caprider
              Hello,

              I am troubleshooting a power supply.

              When measuring a FCL30A015 diode it shows 35 Ohm when reverse biased and 0.05 forward voltage.

              See attached.

              The datasheet does say "Extremely Low Forward Voltage Drop": https://www.alldatasheet.com/datashe...FCL30A015.html

              But 0.05V seems to low.

              Is it gone?

              Should I perform some other test?...

              Help Needed: Reverse Polarity Issue on HP EliteBook 840 G4 – Where Do I Begin?
              by Dev Goose
              Hi everyone, I recently acquired an HP EliteBook 840 G4 (6050A2854301-MB-A01) that I'm hoping to bring back to life. I'm fairly new to laptop repairs but eager to learn and willing to put in the effort to understand and fix this. Any advice or guidance would mean a lot!


              What Happened
              The issue started when the laptop was accidentally plugged in with reverse polarity. Before this incident, the laptop would show a power/charging light whenever it was plugged in. However, now it's completely unresponsive—no lights, no power, nothing. I've been doing some research and understand              ...

              Magic chef oven - thermistor ref voltage issue
              by Use2bavolvo
              I am having an issue with my wall oven temperature control is ~180f out of spec. The thermistor is measuring correctly but I noticed the ref voltage appears to be off. With the thermistor wires attached it's reading ~3.4vdc with the thermistor disconnected it's around I9.8vdc. my understanding is the temp is read off the resistance from the thermistor which leads me to believe the issue is with the ref voltage.

              Another observation is the temp setting and readout at lower temps is way off meaning the oven thinks room temp is 300f and bake relay doesn't engage unless temp setting...

              Tesla 13.7 body sculpt repair problem, need help with finding the thyristor marking.
              by loko
              Hello everyone.
              I have a device that is used to shape the human body muscels and burns fat. Works on the principle of electromagnetic impulses. One thyristor in side is shorted which has only this unknown mark on it ( QC230301 ). I can't find any information about it anywhere on the Internet. I tried to replace that thyristor with one of 1.6kv 800A and after 5min. of work he has burned out again, which means that he is probably weak. There is no schematic diagram on the internet, but that didn't suprise me because all the transistors and chips that are on the boards have their markings...
