convection blower rumble - loose mounting bolts - your experience?

[UncleAnthony]

Hello,

Turned up heat on stove this am. Loud rumbling afterward.
Turned thru heat settings, got worse on high.
Found convection blower mounting bolts kinda loose, tightened them all.

Turned thru heat settings, noise gone, working ok .

Saw similar postings a few months back.

Is this your experience on your stoves ?


Thanks !

My old stove does the same thing. I've been wondering if the cause is due to worn bearings that cause imbalance at higher speeds. I guess I need to check the mounting nuts since they've probably never been tightened in over 20 years.

A touch of silicone on each thread near against the nuts will help with that problem.
