Weishaupt Mechanical vibration

Furnace or burner vibrates excessively during operation

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Unbalanced fan wheel, Loose burner mounting flange, Misaligned motor or pump, Worn motor bearings

Safety: Excessive vibration can lead to mechanical failure. Turn off power if vibration is severe.

Steps:

Check mounting: Verify that the Weishaupt burner is securely bolted to the boiler/furnace door and that all support brackets are tight.
Fan inspection: With power off, inspect the fan wheel for dirt buildup or damage. Clean gently if accessible.
Listen to bearings: A grinding or squealing noise suggests worn motor bearings; the motor should be replaced by a technician.
