Ametek-Lamb 116429 Central Vacuum Motor Replacement

Restore reliable suction and cleaning performance to your central vacuum system with the Ametek-Lamb 116429 replacement motor. This genuine Lamb motor is designed for compatible residential and commercial central vacuum applications and is an excellent replacement for worn or failed motors.

The 116429 is a 2-stage, through-flow motor that operates on 110–120 volts. It features a 5.7-inch motor diameter, ball/sleeve bearing construction, and lead-wire electrical connections. The motor is rated at up to 121 CFM, 97 inches of water lift, and 349 Air Watts.

The Ametek-Lamb 116429 may also be identified by older motor markings such as 6429, 11-6429, or 116429. This makes it important to check the motor number on your existing central vacuum before ordering a replacement.

Compatible Central Vacuum Systems

The 116429 is listed as a replacement motor for several central vacuum brands and models, including:

  • NuTone CV-352
  • AstroVac SR-34
  • ACV 90
  • Pullman BIV-99
  • Pullman BIV-205 — top motor
  • PowerKing PK36
  • Vacumaid P-70

Always compare your existing motor number and specifications before ordering. ThinkVacuums specifically recommends double-checking the motor number because central vacuum systems can use motors with similar physical dimensions but different electrical or performance specifications.

When to Replace Your Central Vacuum Motor

A failing central vacuum motor can cause noticeable changes in system performance. Common signs that the motor may need replacement include reduced suction, unusual motor noise, electrical odors, excessive sparking, repeated breaker trips, or a motor that clicks but does not start.

A motor that shuts down and later starts again can also indicate an aging or overheating motor. However, electrical problems can have other causes, including a defective relay or control board, so proper diagnosis is recommended before replacing the motor.

Replace the Motor Instead of the Entire Power Unit

Replacing the motor can be an economical way to extend the life of an existing central vacuum power unit when the collection canister, electrical components, and other major parts remain in good condition.

Before installing a new motor, inspect the motor gasket and mounting area. A properly sealed motor is important for maintaining the vacuum system's performance.

If the power unit is significantly aged or has multiple failing components, replacing the complete central vacuum unit may be a better long-term option.

Important Compatibility Information

Always verify the motor number before purchasing.

The Ametek-Lamb 116429 is commonly associated with the NuTone CV-352, while the NuTone CV353 uses a different motor configuration. Don't assume a motor will fit just because the model numbers are similar.
