I'm sorry to hear about your problem with your unit. I know this can be frustrating. In order to help, I would need the full model of the unit. That way I can pull up a wiring diagram. The blower is controlled in different ways depending on the unit and age. For example, it could be a bad board causing this in some units.
Carrier does not use a "+" in their model number. Could you have read that wrong?
Sounds to me like a bad board. The IFM (indoor fan motor) is controlled by a contactor which is controlled by the board. Have you tried flipping the board over and inspect it for burned spots or damage?
Is this a 460 3 phase unit?
can you verify that?
Look on the tag on the unit. It should tell the supply voltage.
OK, inspect the back of the board, too. Thanks.
8 flash code means " IGC (board) has sensed internal hardware or software error" This would seem to verify it is a board problem.
Nope, not with that flash code.
