Title: York Dual Stage Furnace Board... 2 in 2 years
Post by: jasunderland on November 04, 2019, 01:24:40 PM
hey guys, appreciate some help.

I have a York Furnace that the main board went out last year.   I called in an independent tech to come out and he said the board looks like it is fried.   some monies later, he installed a new one and everything was good.    Fast forward to this year and same thing happens....  From what i recall both were on windy days...   

Model number YP9C080B12MP12CA

Here is a pic of what is fried on the board.  The Tstat still works....  Any thoughts as to why this would happen and anything I can do to prevent it (surge protector)?

York is well known for having one of the worst boards out there.

Im learning that real quick.   Any idea if a power surge would cause that?  or is it internal?

I'm not sure if a surge protector would help unless this was in fact caused by a surge.  Is that rust on those burnt out electronics?  Maybe a summer time AC water leak is causing this to happen.  Is that a streak down the white sticker?

It worked fine for about a month this winter.   I'll have to look at it to see if there is anything above it to cause water to drop on it.
