Help saving this power controller for FURNACE

[imcool]

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

Re: Help saving this power controller for FURNACE

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.
