    the noise you are refering to is the blower an undersized return air could cause excessive noise.due to force of air being drawn in. this is a big problem with gas upflow furnaces. enlarging filter area could lower it some. usually insulatiung return air cavity can quiten somewhat if it is in a closet. in the attic this problem can be fixed by extending the return air duct to creat a baffle for the noise

    That is a unusual problem with the newer furnaces. They use what is called an inshot burner assembly. The burners are only about 4" long, sit about 2" away from the heat exchanger and literally shoots the flames into the heat exchanger (much resembling the flame out of the back of a jet engine). this helps the furnaced acheive its efficiency. though some furnaces are quieter than others depending on manufacturer. Be thankful it is not a older lennox "pulse". those furnaces required a 6" round, 3' long muffler on the vent pipe, and then you still had to insulate the room it was in because they were so loud.

I have installed a ton of Kelvinator furnaces. I have NEVER heard a loud one. The installer should cooperate. Call your building inspector. I bet this guy did not even pull a permit. If it is the burners that are loud then have your gas pressure checked in the furnace. Do you have a noisy induced draft motor. If so replace it.... you are under warranty.
Start calling your installer every night at 3 am. Call him every time you walk by a phone. He will get the hint. You need to as loud to him, as your furnace is to you.
Call Kelvinator... you can get the number on line. tell them about your problem they do not want bad advertisement. they will find someone to solve your problem.
Good luck....

The new Weatherking 13% SEER was installed 4 days ago. The blower/furnace unit is very load; almost a harmonic sound tha ttresonates into the home.

Weather King is a builders model brand made by Ruud/Rheem that is not insulated to reduce noise. Recommend having the installer insulate with duct liner inside the blower compartment and return air chamber, which will make it quieter but it is a builders model as I stated, so don't expect it to be totally quiet.

At tstat press options. Press installer setup. Yes, you are qualified. System settings, non heat pump. Gas/ oil heat. Save changes. That should do it with no wiring changes.

Bryant Plus 90i furnace vibration

You have not mentioned if the vent pipe has any anti-vibration mounts or not. If not, use rubber mounts to suspend the vent. It may be transmitting your noise.

Code #33 on Bryant 355MAV 90i Furnace

'Limit or flame rollout switch is open'. In my case, the flame rollout switch had tripped due to an overheating? I had to push the button between the wire leads to reset the switch. Then when I turned the power back on, the furnace started up like normal.

Why did the switch overheat and trip? My current theory is that there was a rubber grommet around a pipe near the switch that had slid down and was no longer sealing the furnace?
