I have a Mr. Rooter brand garbage disposal that is frozen. I can hear a hum sound when the switch is on, but nothing is turning. I got my tool to stick into the bottom of it to unfreeze it, but on this particular brand of garbage disposal, there is no hole there! In fact I can't find anywhere on the garbage disposal to use the tool to loosen it.

Can you tell me, how can I unfreeze this brand of garbage disposal?

I've never owned this brand before (this is a new home for us). I can't find anything on the Internet or youtube to show me how it's done, nor can I find a manual for it.

Thank you!
