    Help saving this power controller for FURNACE

    hello,
    I have an old furnace in house and this is its working control module.

    How can I collect information/date/readings/measurements from this working module so in case if something happens to this working module I can cross check from the information noted down and find broken component easily.

    Should I take diode mode measurements of all the soldered pins on the board?
    Any other ideas?

    I am not too good electronics troubleshooting





    thankyou

    dont bother with readings, other than maybe the coil - but i doubt you will get any.
    a lot of ignition coils also contain other parts under the resin.

    what may be usefull if it blows will be a record of all the resistor colour-codes
    because if one burns up you wont be able to see the colours afterwards.
    also consider either replacing the fuse with a ceramic one or puting sleeving over the original.
    if the board shorts out it could shatter the glass fuse and make a real mess!

      Thanks,
      I was thinking to go on green side of the board and use diode mode measurements on each of soldered point on green side.
