Blown blue Thermistor on Power Board
I'm really hoping someone can tell me the specs for a blue thermistor on the powerboard near the heat sink and on the edge of the board. The board shows R15 under it. It appears blown out and hopefully if I get some info I can just replace it. Help guys!!! I contacted Beckman Coulter and they wouldn't give me any information telling me they could sell me a board for $2k!! Thanks, but no. Reply
