Post My A/C fan, blower wont stop running.

CARRIER control board 302075-302 RELAY MESSED UP and stuck. THE BLOWER RUNS CONTINUOUSLY even when thermostat is on off position. Which relay to change? Complete Control board are pricey but I think, I have to change. What is the new replacement for this older control board 302075-302?

For a temporary fix move Gc wire to Y on the control board.

There was someone with a similar problem a few years ago. See http://www.doityourself.com/forum/ga...-switch.html#b for more information. It appears that your board is available on eBay for ~$50.

If you think the relay is just stuck, you could try gently tapping on both relays to see if it restores normal operation.
