The motor appears fried. After pulsing through some very dense food, blades spinning hard and little traction, the motor kaputzied on me. Waited a day, and still no motor, even though blue light still comes on. Can I take this apart and fix it somehow? Would prefer not trashing.

Re: How to fix fried motor, bL1900R?
You cannot fix a fried motor, for what its wroth you might be able to replace the current motor in it but with that said you looking at a cost of a new blender. You will not be able to fix a motor that is fried you will need to replace the motor in this unit. I would rather you not throw it away ether but facts are not fiction in your case. You might check with the manufacture most of these have a 5 year warranty.

It sounds like the blade has become jammed on the motor shaft sleeve. You will be up for a new blade and motor shaft sleeve to sort that out. They are not expensive and it is the only proper fix for them. If you replace nothing it will happen again pretty much straight away and if you only do one the other damaged part will wreck the new part. To solve the not turning on problem which is a separate issue it will very likely involve replacement of either the bowl or the lid. One is as likely as the other, I have both parts in stock so I try one or the other to decide which one is the problem. Getting the blade off is a real chore, I have a small chain (with welded links so very strong) I put a couple of turns around the big blade shaft and fix it there with a shackle. It's about 2.5 meters long so I attach the other end to the leg of my bench and accelerate the motor unit away from the bench. The chain comes tight and shocks the blade off. I then drill a hole through the motor shaft about 8 mm from the top, attach the chain to that with a shackle and shock it off just like the blade. New parts now and job done.
much that is what happened to me. I found that the motor has 2 "thermal
cut-offs" (SEFUSE 113oC). If the motor heats up even a little, these
babies kill your blender. They are thermal fuses. Once they blow, it is
over until they are replaced. To fix this, the motor must be removed.
The spline gismo on top of the blender unscrews with reversed threads.
I suggest unsoldering the lead wires from the power supply board, and
replacing when done. The cut-offs are inside the taped on white cloth
insulation on the top of the field magnets near the brush assemblies on
both sides. I replaced them (both were blown) with 2 of NTE8242 ($1.60
each, 240oC 15A). These are way too hot, but that is what I had on
hand. I thought that the electronics were defective at first, and I
replaced the entire board assembly with a small/cheap ceiling fan wall
switch /speed controller from the hardware store (600W 5A) for $10. The
root cause of all of this is that the motor fan is not working. The
airflow is blocked by base. I put small extenders on the feet and now
there is much more airflow. Only time will tell if this is an effective
fix. etc. It really makes me wonder how it got past UL
Does the motor still work if you take the pitcher off of the base? If so, the rod that's in the blade assembly is probably corroded. The blades are connected to a metal rod that passes through a brass tube through to the piece that makes contact with the motor when you put the pitcher on the base. The grease wears down eventually and if you don't pulse and run the motor for a long time at once, the heat can corrode the bar and cause the blade to stop spinning. You can either disassemble the blade unit, or buy a new blade unit online. google blender parts and you can get one for $10
your blade assembly is corroded. take it off, and using a rag, grab the blades. using another rag, grab the other end (probably rubber) and turn CLOCKWISE - it's threaded reverse, so you have to turn to the right to loosen, not the left like usual. I had to clean out the rod that connects to the blades - it was all nasty and corroded. I cleaned it with my Dremel and regreased with a tube of grease I keep in the garage, cleaned all other parts with some Dawn, dried well, reassembled, and works almost like new. I'm guessing I ran it too long without pulsing the motor and the heat corroded the rod that's connected to the blades. OR you can buy a replacement blade unit for about $10 online on a blender parts site
You have to unscrew and disassemble the blades - pretty easy, just take two rags and grab the blades with one (so you don't cut yourself), and then turn the rubber piece on the other side COUNTER CLOCKWISE, opposite of what you would do to loosen. the rod that runs in the middle that's connected to the blades on mine was all corroded, so I sprayed it down with WD-40, took my Dremel to it and smoothed out the corrosion, added some fresh grease ($2 tube goes a long way), washed the other parts with some Dawn and dried completely, reassembled and it runs much better! Not sure how long it will last, but I have a feeling that one time I ran the blender for a long time instead of pulsing, and the grease that came with it couldn't handle the heat from it turning so long. Anyway good luck!
[Note: I have not ordered from this site yet so I can't say how reputable they are.]
They offer the glass jar, blade assembly, and other parts for the BL1900R. Judging from reviews, it may not be long until something else goes wrong.. I am gong to order the replacement part this one time. If anything else goes wrong though, forget it. Too bad. Black and Decker usually makes good stuff.
