York DM048N Blower Relay Issues
Was passed on this info to research, checked here and Googled but came up with nothing. We have a job with close to 20 of these gas packs on the roof. I'm being told that out of 20 we have lost about 10 of the blower relay boards. Anyone know of any issues or bulletins about a bad batch of these?Dad's Hideout The online mancave for dads

I am from Canada, I am not sure if this is the same issue I have had. I am having a issue with the combustion gas causing condensation, and then dripping on the board and then shorting out... This has been the main failure of many boards.

add a longer post purge (5 minutes). should take care of condensation problems. make sure it's not underfired.
i've had lots of problems with the older ETD boards causing the blower contactor to chatter
