Do you have the pitcher for this model blender?
Hi Margo, thank you for reaching out. The part which you are looking for is the jar, part number PS11756236. We hope that helps!
Need instructions to remove old coupler (part #7 in diagram) and replace with new. Can't seem to loosen the shaft once the blender is opened up.
Hello Ann, thank you for your question. We have a testimonial from a previous customer that may be of some help. " Put masking tape around the coupling and put the coupling in a vise upside down. took the bottom apart and unscrewed the main shaft screw. ITS LEFT HAND THREAD!!! Screw on new coupling and put the bottom back on. The masking tape is just to protect the finish." We hope this helps.

my motor works but it is not spinning. how do I know if it i the coupling nothing is clogging blender. also my blender coupling is steel and the one on your site is plastic. where can I take my blender to see what is wrong
Hello Sharon, thank you for contacting us. If the motor runs but the blades won't spin, the drive coupling has likely failed. Remove the jar from the base. You should see a small plastic or metal piece with tabs or teeth sticking up. Spin it with your finger, it should turn with some resistance. If it spins completely freely with no resistance, the coupling is stripped and not grabbing. You will need to replace the coupling, part number PS11751771, to fix the issue. Glad to be of assistance!

Really Easy

I didn't realize there was a spoon in the blender and it made a total racket as the blades and housing were falling apart. The blender jar, blades and housing are all one piece so my less than 2 month old blender was completely trashed. Rather than spend $100 on a new blender, I spent $24 on a new jar... popped it on the blender in plac
... Read moree of the old one and it's better than new! And I'm much more careful using it!
