I have a remote only Hampton Bay fan, everything works except the high speed, it worked last year.:confused:

What happens when you switch it to high?

There is only one speed that works, if I push HI the fan turns on about MED, if I push LOW, or MED the fan turns off.

Sounds like the fan has a bad capacitor. But since you're dealing with a remote fan you might be better off just returning it to Home Depot for a replacement under warranty.

Will home depot require the original box.

No. You might get someone cranky behind the counter who tries to be tough, but their policy doesn't require it.
