Where can I order on line a mixing paddle for a Black&Decker All In One Pro Automatic Breadmaker Model B1650?

Just let it go and find out. It should be in your manual

Gluten free recipes are thicker and stickier than wheat and will probably wreck your bread maker. I had a 2500 model and it broke while making a gluten free bread, so yours will likely be the same. I found it best to keep the dough more liquidy than solid to avoid extra strain on the motor and paddles, but it will affect the outcome. There are lots of gluten free recipes on the internet, just do a simple web search.

When your machine started kneading did you notice if the ingredients were actually mixing? Sometimes the drive belts on bread machine break and there is no mixing (the paddle doesn't spin around)

Try soaking it in olive oil overnight and apply some to the bottom, see if it frees up the paddles.

You may be able to order a paddle for your Black & Decker B1561 Bread Maker from this site:

Before ordering you may wish to inquire whether the Paddle 500 is a suitable replacement for the B1561 or if they can supply the correct part.

Was not able to locate manual for the B1640; perhaps the manual for the following will be sufficiently similar to be of assistance.

B1650

Your model number for the all in one pro should be a B1650 (single paddle model)

If that is correct then this is one source for the paddle:

An informationl note about Black and Decker products is that there are replacement parts for anything they make as long as they have no discontinued the model number. Once the model number is discontinued they have aftermarket replacement parts for 5 years only.
(your replacement paddle is starting to show up as no longer available)

The orignal paddle part number is: 429592-00

Here is a 2nd source for the paddle:

I had great success in finding what I wanted for my breadmaker at http://breadmakerpartsemporium.ioffer.com/. They have manuals and parts for most breadmakers at very reasonable prices.
