Carrier 69NT40 Fuse 1 blowing

[djbe]

Hi,

Wonder if anyone can tell me what fuse 1 (3 amp) on the relay board of an old 69nt40 feeds.

Looked at one late this afternoon, replaced fuse ran fine for about 10 minutes then failed again.

Need to go back in the morning and sort it out.

Cheers,
Djbe.

Hi have you checked the SMV?

Not yet but that is on my list this morning following a study of the circuit diagram. I did have a glance at it yesterday and it looked extremely corroded.

Yes thanks, faulty power supply board. Also disconnected the SMV as badly corroded.
