What to note: The 116429 motor may say 6429 or 11-6429.

What motors it replaces: Replaces 115923 and many others with the same dimensions and characteristics.

When to replace: The signs that a 116429 Lamb motor needs to be replaced include: mini breaker popping, electrical smell, excessive blue sparks seen from motor top, you only hear a click, motor shuts down on its own but works later, or its life of 700-1,000 hours has been used up. (If you don't hear a click, then your relay most likely needs to be replaced and your motor may be fine). Five percent of the time, the minibreaker will go bad as well as the motor. If this happens, replace the motor and then evaluate the mini breaker.

How to replace: It is not difficult to replace the 116429 Ametek Motor. There are three to four screw brackets and a couple of wires. All of our customers are amazed at how easy it is. NOTE: There is no core trade-in. Used motors are thrown away. Click here to read and print out our step-by-step motor replacement instructions. Note that if the unit bolts into metal brackets then the ground wire can be snipped. If plastic then attach the ground wire to the ground from the power cord or anywhere to metal on the unit.

Replacing motor brushes: The Lamb 116429 vacuum motor has carbon motor brushes that can be replaced. This should be done before a motor is "on its last legs." Read more about changing the motor brush on the detailed motor brush how-to page. If you are ready to replace your motor brushes, here is a link to the Ametek 116429 Motor Brush. You will need to buy two.

Your website design made it very easy to find the right motor for my 30 year old in-wall vacuum. I quickly found the correct part, and the instillation was easy. Works great! Hoping for another 30 years of use.
