Ceiling fan went on sporadically with switch, now won't turn on at all with switch or without. Im a renter... called landlord and they stated you need to get a remote which they lost. Trying to obtain a remote, but seems odd it won't work via the switch. I already replaced wall switch myself.

Try this page for replacement Harbor Breeze ceiling fan remotes (http://www.ceiling-fans-n-more.com/harbor-breeze-ceiling-fans.php). There is a universal ceiling fan listed there for Harbor Breeze fans. It should solve your problem :)

Check the product details. It's compatible with most Harbor Breeze fans.

Beats looking for the original remote from Lowe's/Home Depot or other.
