Question about replacement parts for a Bryant furnace.


It is my understanding that I did not get the 10 year warranty.

Question about replacement parts for a Bryant furnace.


Bummer. How bad is the noise. I have had them be noisy because the metal plate above the motor rattles. Some of those units are prone to vibration from day one. If not too bad you may want to let it go for awhile so you get more use/$$ worth from it. It is a bugger to replace so beware.

Question about replacement parts for a Bryant furnace.


It has been a problem for a couple of years and it started just out of the 3 year warranty. I had the person who installed it and does our yearly service (authorized dealer) check it out when it first started and I thought it was OK for a while. I did notice what sounded like a distant jet plane sound in the bedroom when the furnace was running and it took me a while to figure it out because it was quiet by the furnace. Anyway, I found the problem to be the vibration of the motor vibrating the gas pipe running in the floors and making noise between the gas pipe and the metal clips that support the pipe in the floor. I did some things to reduce the vibration but ended up coupling the pipe to the floor so it couldnít rattle but it would some times vibrate things like light pots and pans on the stove which is directly about where I coupled the pipe to the floor. Just a month ago for the yearly checkup, I had a piece of flexible pipe installed to the furnace to break the vibration in the gas pipe.

With the above story, it probably sounds worse than it isÖ I did turn the motor with my finger and can feel something there in the motor that is not smooth and is not right. It does make some noise and it bothers me because I know something is wrong and running a motor with a bad bearing or something out of balance is only going to get worse and fail some day. Right now I like the $1000 more than fixing the noise but if it fails Iíll like the heat more than the $1000.

Thatís why Iím here to see if I can get something cheaper and fix it myself because right now itís working and the problem has been going on for a while and it may go for a couple of more years.

Like I said, it is difficult to change because of all the hoses attached to it and the difficult way it has to attach at the back etc. Sometimes the hoses to the trap crack and you have an even bigger job. Such is life.

Check the 4 small, rubber grommets that hold the motor to the inducer. They deteriorate with time and caused the motor to be uneven and run noisely. I bought some rubber washers and installed them and then adjusted the screws until the motor was balanced which running. Has worked for 3 years and saved $750.00

A 355 bryant furnace that is 10 years old most likely has a cracked heat exchanger I would look at replacing the furnace before putting all that money into it I sell the replacement motor for $400 installed it only takes about 20 minutes to change but you have to be careful to make sure the drains and pressure switch hoses are connected properly. to check the heat exchanger pull the high limit switch and look at the first dimple with a flashlight that's where it usually cracks on both sides
