Thanks for any help you can give I am a novas on circuits. Here is what I need help with I have an electronic air filter that quit working. I took one end of the caps & unsolder them & tested they test good I then tested resistor #1 & it is open. On the resistor is is stamped TRW 8402, 836-0151. I searched & could not find this number. The diagram shows it to be a 30Meg but does not show the watts The questions that I have is... How may watt resistor do need? I think this is a thick film power resistor is that correct? Where can I buy just one on line. I use to go to a local store & just show them what I wanted & they knew what I needed but they are gone now.
