sorry for the off-topic, dunno where else to post misc electronics questions, as this is by far the techiest section of the forum
ok so i have a kerosene shop heater with a bad board. the ignitor went and took a surface mount resistor on the control board with it. The only marking on the resistor is 'DALE R1F'. From what i gather R1F is the resistor series but doesnt tell me the resistance or wattage. This board is like $100 and id like to try to fix it
here is the patent for that board with some schematics and descriptions
http://www.freepatentsonline.com/5470223.pdfsee R15 in figure 2A. Thats the blown resistor its not specifically described in the text (from what i saw) but it does describe the IC1 microprocessor it is connected to as a ST6210. Datasheet might be found here:
http://www.datasheetarchive.com/ST6210-datasheet.htmlhopefully someone can help me figure out the size of this resistor, i dont know, other than getting an assortment of resistors and starting with a high wattage high resistance one and swapping them with lower resistance values until it works. Any clues? if i desolder this maybe there is some more size markings on the back?
