What to note: The 115684 motor is the 240 volt version of the 115334 lamb Ametek motor, and this is the all metal version of the 117465 motor.

What motors it replaces: 115472, 115837, 115332, 115334-W, 115441, 115440, 115639 and 115937 motors.

When to replace: The signs that a 115334 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 900-1,200 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 115334 ametek motor. There are three bolts 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 115334 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 115334 motor brush. You will need to buy two.

Installed it myself by matching the motor and 3 wire connections I removed. Works great. Good thing I ordered the matching gasket. No way I could have used the old one. I suggest MD add the gasket to the motor delivery and adjust price as necessary.

It would have been helpful to have a couple terminal connectors.

I have had my central system for 20 plus years. The motor died. I ordered and received the perfect replacement from this company.

After 45 years, our Sears central vacuum finally went dead. I searched online for troubleshooting videos and watched this wonderful video by MD Central Vacuum. Based on that video I was very confident it was the motor. I then saw another terrific MD video on YouTube on how easy it was to remove the old motor and install the new one. This was a step by step process. When I called the company they assisted me with what I needed to locate: the motor model number, etc., so I would order the correct motor and gasket. Everything worked like a charm. The motor arrived, I reviewed the MD video again, and had no problem replacing the gasket and motor. Our central vacuum is back and running! 5 Star kudos to MD Central Vacuum for their easy to understand and valuable videos. The staff was super, too, in assisting me with the correct order. Anyone with a central vacuum should go to MD Central Vacuum!
