Goodman ARUD blower unit, 7kw heat kit, fuse on the ele. Blower time relay keeps blowing, do I need a new board? Thanks,, wes

Check all of the wiring. Anything burned or discolored near the connection point, needs to be replaced. On Goodman equipment, I always go at least one wire size heavier. If there is enough extra wire, it would probably be a good idea to replace the push on connectors even if they don't show any signs of burning. Loose connections will cause a high amp draw & burn out relays.
