Sorry for the confusion, but the 903404 is a combustion air blower, and the Ja2n218nv#621080 is an inducer / exhaust vent vent
There's an air duct to draw in side air for combustion in a mobile home furnace.
The warranty on mine was 90 days, and you might need to contact the vendor to find out the most accurate

A vibration can be heard coming from the fan blade assembly. When the unit starts up, there is some noise. The thermostat has not been set at a high temperature for example, so it has not run all night. It then quiets down after running for five minutes. I have noticed that if I run it again while still warm, it makes no sound. The last replacement, the same item and the same manufacturer, lasted only It does not look like vibration will be able to destruct this one as well. I adjusted the mounting screws, but there is still vibration.
On my search for something I needed, I came across just what I needed at a very reasonable price. Having said that, I would rather have paid more for this miracle worker than endure these hardships. Thanks a lot! The Amazon website. When the winter months roll around, I have to make sure my heater is working.
During last year's summer, the pressure switch went out and we discovered it only when it was critical. My first thought was that it was the pressure switch, but it turned out that The part was easy to replace (about 15 minutes) and we're back In addition to being much quieter than the old one, this one is also much lighter.
It was easy to install and worked perfectly for almost two I was unable to use it the next day because it made a lot of noise. In taking it out and examining it, I found that 3 blades on the top fan were broken and 1 blade had fallen off the bottom fan. As soon as I called the customer service number, music played for a while as if I was on hold. Each time I called, the same thing happened. In any case, almost 1 month have passed since the refund was issued, so money has gone.
It is the coldest night of the year, and that is when the furnace stops working. We got the fan running for a short time with some duct tape and a bailing wire. We ordered a replacement, and this came quickly.
Instructions were provided, but it took about 15 minutes to install due to the fact that it was an exact replacement. Thank you.
I would strongly recommend it.
