Certainly wouldn't rule out the blockage as your friend suggests. Perhaps pulling it out, and a flashlight and if necessary a mirror to get a good look in there. May have to head up to top for a look as well. As long as blower sounds like it's running good speed wise.

There should be a gasket between the mounting flange of the inducer motor and the furnace. If you do not have that you can use a small bead of blue or red silicone caulking to seal it. Hope this helps you. Thanks

Draft inducer fault


Pressure switch is not proving that the inducer fan is running. First check to see if draft inducer fan is running that will be the small black fan that is hooked to the vent pipe. If fan is not running then replace fan. If fan is running then check the small rubber tub that runs from inducer blower blower to draft switch make sure the hole in the blower cage is not stopped up with rust you can clear this with a sewing needle. If this is clear then check the pressure switch with a volt meter make sure it is getting 24 volts to the switch and through the switch. If it is getting to switch and not through switch then replace the switch.

Why is my 1987 300e Mercedes making a loud clanging noise at start up?


I would think the honeycomb ceramic "Brick" inside the Catalytic Converter has broken up, makes a terrible rattling when this happens.

The fan motor went out and the furnace is not even 5 years old.


I have an Amana High Efficiency furnace that I purchased 5 years ago this past October (2009). My furnace started making a horrible noise last night and then stopped working. The repair person, told me my draft inducer motor needed replaced, and showed me where the plastic fan blade inside of the inducer was "chewed up." Of course my first question is, "How can a 5 year old furnace need such a costly repair already?" The only answer I received is that it will cost me close to $500.00 to have the situation remedied (service call, parts, labor). I started looking around on the internet today, and discovered that high efficiency furnace inducer motors are usually encased in plastic and the motor fan blades are made of plastic rather than metal like the lower efficiency models. Turns out that these plastic blades over time can't withstand the high heat generated and in time (they estimate 3-4 years) break. The damage to the blades causes an imbalance in the way they spin, which in turn, generates the resulting problem of a damaged draft inducer motor. Appears this is a design flaw. Yeah! I'll say. I spent $3100.00 for a brand new furnace and 5 years later I'm paying another $500.00 and apparently can look forward to doing the same in 3-5 more years! Maybe this answers in part your question?

When a furnace is replaced with a newer style unit like yours with an inducer motor, they sometimes use the old vent pipe. These old style vent pipes are transite (light weight cement), the moisture created from your furnace exhaust is caught on the cool transite surface and runs back down into the blower blades or wheel bringing a white mineral deposit with it which causes your problem. The vent should nave been replaced with the heater using a metal vent material. You will need to replace your inducer motor assembly and vent pipe to prevent a recurrence.

The draft inducer makes a vibrating noise at the beginning of the heating cycle and at the end.


Either you have moisture in the fan housing or the fan blade lost a counterweight. Pull off the lower hose going to your condensate drain and check for moisture. If you find none, you will need to replace the inducer fan assembly.

HEATER MAKING LOUD NOISES


Check the draft inducer motor for any partial blockages or dibri.

I've seen sticks, birds nest particles and pieces of deteriorating fan blades (squirrel cage type fans) cause this.

You might also find that the inducer motors bearing are going.

If its a loud vibrating grinding type noise, I'd suspect bearings or missing pieces of the blades. (unbalanced)
If it's a clanking type noise I'd suspect loose items hitting the fan.

The inducer motor will only operate right before and during burner operation, while the blower motor can operate at any time depending on your setting.
