How do I get replacement wheels, it was dropped & the plastic wheels broke?

Put a 4 to 5 inch screw through the plastic tab was if you don't have the resources to get new one

while you have supplied few details as to the parts you require , there are important details left out .
people have to know the type of gears involved --spur cut , bevel, spiral beval
wheel shaft diameter , thickness, drive cog shaft dia , thickness
find a retailer that handles power transmission products such as CBC bearings ( yes they do sell cogs)
I went and searched wheels and pinions for small applications and found sites that sell wheels and pinions but not knowing all of the information , pinning down a manufacturer was a no go
if you take what you have to a local engineering shop , many have the ability to cut gears from blank stock and ask the price and shop around or they could have a supplier that they can put you on to
as a point of interest , the cog that is stripping (4) may be the weak point in the drive line to prevent damage to the rest of the machine in an overloaded or jammed situation

Check the fuse inside the oven.. It is on a wire housed in a white plastic. Twist it and the fuse comes out. The fuse is about 1/8 inch dia. by 2 inch. Be careful to replace it with exactly the same rating.

Check the fuse. It is on a wire plastic fuse case colored white. Twist to open, replace a fuse 1/8 dia x 2 inch with an exact replacement. Be sure that the cover is placed back well when you are done.

I see the description says, "500-lb. capacity model has ... 5in dia. casters for extra stability. .... Four nonmarking casters two swivel."

As to screw size, I can't estimate without seeing it, so I would suggest going to a place that sells it.
But you could also ask Rubbermaid:
"For replacement parts, please contact Rubbermaid Consumer Service by calling 1-888-895-2110 Monday through Friday, 8:30 am to 5:00 pm ET or by email using our contact form."

I don't have a glass solution, but if you frydaddy is like mine, it has a 7.25 inch dia lid. For about $2 the "Glad Big Bowl" (6 cup size) plastic containers have a lid that fits pretty well.

If I remember correctly, the front is 19" dia and 3" wide, rear is 15 or 16" dia and 5" wide. In any case, they are not the same front to rear.

The steerin wheel screws have come loose inside the steering colum, if you can move the steering wheel up and down and back and forth you will have to remove the air bag the horn and horn button and tighten the two screws that are tork heads #8 to fix this issue.
Comments: Aug 20, 2009- If you want to fix this yourself you can do this it takes two to three hours with out the right tools, If you rent the tools to remove the steering wheel and the u clamp to remove the snap ring it will cost you almost nothing and would take an hour. You can rent it from schucks or autozone, you need steering wheel puller and screw on u clamp to remove plastic cover to ge tto the screws, I am also assumeing it is a tilt wheel. Disconnect the battery pull two bolt air bag retainer covers remove two bolts holding air bag on, next disconnect the air bag, Next remove 3 philips screws holding the horn assembly plastic and metal ring, Put tothe side in order how the screws and two parts go, if there are wires for a cruise control disconnect them. Next Remove 3/4 inch center steering nut, install U bolt on the bolt thread that you removed the nut off of screw down till the plastic cap is 1/4 inch down allowing you to getto the center snap ring, using too picks work snap ring out of the grouve then remove the u clamp. once you pull the clap off the plastic plate whell come off and the plate is keyed to go on one way. after you remove plastic cover you will see three screws tork head type #8 or #6 buy a tube ot thread lock #605 remove the screws and put a drop on each screw then screw down. once screws are tight make sure the steering ball is not broke it is a plastic ball with a notch on one end with a spring on the other. Connect the battery up, install key and turn the key on put foot on brake then shif the shifter selecter back and forth if it operates somothly your done, if it gives you trouble still then check the pin in the pivot point on the shift lever, if it looks broke hammer it out and take to the parts store get new roll pin and hammer new one pack in with a center hole punch. then reinstall the parts. If you run into trouble you can post here and I can help you more.
Thanks for using fixya and have a good day!

with the cover in your hand pull the cord out with a pair of needle nose pliers or a little screw driver and where the cord go through the case and before the wheel. pull 5 to 10 inches out and wrap the cord around the wheel turning the wheel but not winding the cord on., do 3 or 4 wraps then pull the handle to get all the cord out and let it retract. if not enough rewind just repeat with 2 wraps
