Does anybody get this moaning sound coming from their convection fan motor ? I have put a gasket between the fan and body of the stove and still the moaning motor noise translates through the body of the stove. It is NOT the hamster wheel blowing sound or sucking sound. Sound more like a cheap motor. My stove is 2 months old, not sure if they are using cheap blowers or I just got a bad one. I have tried everything to no avail. Even have the stove sitting on rubber feet to absorb the vibration. Love the stove but just about had it with the up and down moaning sound. My combustion motor is fine, wish this motor was as quiet.

You say it is a new stove...sometimes those sintered bushings need to break in a little or other times the fan's fasteners cause a binding in the metal where fan is mounted to stove chassis, but it is very probable that motor is just defective. ;)

Unfortunately they are the best blowers available. We do not select products based on cost. As more production gets moved elsewhere by our suppliers ( Fasco ) all the time. Sometimes quality is not what we would hope for. We are constantly looking for better but as of now there are none available. Most are good occasionally someone pulls the short straw I guess. One thing we have found that works great is white spray grease with a straw it can be found in most auto departments. Spray 2 or 3 small squirts in the 2 oil holes they are on top of the motor when mounted to the stove. They look like a little U shape. Also make sure the blower does not have a lot of dust in the blower wheel causing an out of balance condition.
Thanks, Dave

Thank You, I'll give the grease a try. I hear ya on quality of some products. What used to be considered top quality is not anymore, and when you have to rely on vendors to supply you with such items you are at their mercy till you find better.

So I pulled the fan assembly off and greased the motor. With the fan off the stove is seems quiet , normal sound of what you would expect from a blowing fan. As soon as you put it on the stove you get that moan like sound coming out the top grates. The stove is acting as a echo chamber . Gaskets or no gaskets , the blower motor sound is amplified through the body of the stove. Very annoying sound. I did notice the motor is mounted to fan body with rubber so that seems to lesson vibration there. My thinking now is that the lack of two bolts and just having a lip that the fan slides into for mounting is creating a area for vibration to take place. Four bolt with gasket would be better I think.

My stove has 3 bolts and never had a noise like what you have.

My furnace has removable steel plate baffles. Sometimes as they change temperature while I'm loading, the blowers will cause enough vibration to make them rattle, it sounds like a moan I guess especially when the load door was closed.. If I tap on the baffle, the sound will stop until they change temperature again and I get the same sound. Its the steel creeping as it expands and contracts that sets up the right conditions for the baffles to rattle. At first I thought it was a blower going bad. I was enlightened to discover the rattling baffle. :D

Its a long shot, but check for something vibrating in your appliance.. Since, it seemed fine while you had it disassembled.

Take the fan back out and then give the mounting lips a little tap w/ a rubber mallet to make them a tad bit snugger. ;)

New stoves have a 2 bolt mount. Where the other two holes are , instead of bolting it you slide that end into a slot. There for with out that end of blower being solid, you get a gap with slack. And for vibration to take place that gap need not be big. They skipped tack welding 2 more bolts and went with a slot. Metal on metal with no room in that slot to place a gasket to absorb the vibration. So basically I need to bend the tab down to expand the slot enough and try to get a gasket in the to snug up the fit.

Dave,
When soldering wires together, they use shrink tubing to insulate the wire. If you put shrink tubing over the tab, and heat with a heat gun or hair dryer, you will have a non-flammable gasket. You can get this at Radio Shack and some auto parts stores. It comes in various lengths and diameter. It's thin, looks like a straw.

I like that idea. Thank You That should do it. I was worried about the heat and what I should use. Thanks again

Dave,

My convection fan from day 1 has always groaned when running. It's not the fan itself, but a vibration through the entire stove, it gets pretty loud.

I've done some things to try and isolate the stove from the tile floor. 1) the stove now sits on 3" high temp rubber acoustical isolation pads (made them at work) 2) I cut a wedge shaped piece of wood that I jam under the convection fan. This really does the work, once the wood wedge is hard and fast in place, all vibration stops, and all is pretty quiet. I have to push the wedge back in every now and then, no big deal.


take care.

What I ended up doing was bending the tab down in back and making a thin rubber gasket. Slide the fan unit in place which is hard to do because of the gasket :mad: Once I got it in place I put the two nuts back on and tightened up. This along with half inch rubber feet all the way around has quieted the stove up. It is a design flaw by not having a 4 bolt system with a gasket. The fan vibration transmits into the stove through the air chamber that distributes the hot air. I have noticed that the owners of LL quickly disappear off here once their suggestion doesn't work. But thats what brings us here RIGHT ? to help each other solve our problems with these stoves. Thanks for your suggestion, sounds like you went through everything i did. Take Care
