Digidoor ii The worm gear is vibrating and make a horrible noise.

There are lots of words in here, but even after reading many times they don't make sense. I can usually tidy up text, but you beat me on this

"T Problem Starts After E Drive For A Five Minutes And T Char Barmas Sub. When I'm in gear and stand in (note driving) the four vibrates worm hard."

especially on the 'T Char Barmas Sub', and 'the four vibrates worm hard'.

Actually after reading it another 20 times, this is regarding an aftermarket amplifier system that the kids use to bust their eardrums and make themselves deaf in later life?

Your battery isn't man enough to run the sound system.

It is always better to get the remote for the door make you have. The same seller does a 4 button remote as well.

Nope, Digidoor II has no battery backup. You need to invest in a UPS or replace the motor.

Digidoor one, Digidoor III and the Digidoor IQ all have build in battery backup.

Sized bearings, jammed gears, sticking door. The humming is the motor trying to turn but cannot as it does not have enough power to move it.

Your worm gear is no longer seated and that is more than likely because the housing cover is probably the old style plastic and it has cracked which allows the worm gear to jump up during operation and turn out of sync. The worm gear turns the drive gear that works the planetary gears which in turn drives the beater. If the worm gear is not turning true then of course it is pushing the planetary out of true as it turns, which causes the beater to slam the sides of the bowl. The question is this...does the beater hit the bowl in the same place on the bowl every time? Or does the beater hit the bowl in different places every time? If it hits the same place then it is probably just a planetary gear of which there are four gears involved and it could be any one of them. It it hits a different place every time it is most likely the worm gear and cover. In either case parts will cost between 30 and 50 dollars. and it takes about an hour to fix.

The problem can get to the point where the game won't even load. What is happening is there is a little white plastic gear with 2 teeth that screws onto the laser. Those teeth ride into the grooves on the worm gear motor shaft. As the shaft turns the little laser gear moves the laser back and forth. After time those little teeth that are suppose to be flat wear a tiny bit and have troughs wore in them. This allows it to slip off the worm gear shaft causing the clicking noise. you simply remove it and use white lithium grease and replace it and it will work like a new one.
I hope this helps!

Its your track

You may have worn agitator dogs, causing the upper portion of the agitator (called the "auger") to slip. Or, you could have a loose agitator bolt. The following link explains how to replace the dogs (if necessary) and how to access the bolt:

http://www.fixya.com/support/r823955-replacing_agitator_dogs

If you need to replace the dogs, the part number is included. You can purchase them for about $5 at appliancepartspros.com. For a little more, you can purchase the entire agitator drive replacement kit. Look for it under the "Agitator" parts section. You can also reference the helpful exploded view diagrams the site offers for assistance.

NOTE: When tightening the agitator bolt make sure you do not overtighten. This may cause damage to the agitator, or restrict its movement. Tighten until snug.

This repair should take about 10-15 minutes and does not require special tools, a repairman, or a lot of money. If you still require assistance, please let me know. I hope this helps you.
