Carrier Weathermaker 9200 blower motor noisy start

I have a Weathermaker 9200 in a home a I bought 4 years ago in the Spokane, WA area. It has worked fine until this fall when it started making a lot of noise as it starts up. It kind of sounds like rubbing metal or vibration. Once it gets to speed the motor runs smoothly. I thought starting issues were probably related to the starting capacitor so I replaced it, it did not solve the problem. The issue seems to be getting worse. Slower longer noisy starts. It sounds like the motor is getting to full speed when it is running. I am starting to suspect the motor itself is the issue. I felt the exposed side of the motor today and noticed the shaft cover was kind of warm. I am wondering if the bushing or bearing is wearing out. I will post a picture of the furnace label shortly.

Picture is probably too large. If you reduce the width to 600px it should post okay.

Weathermaker 9200 is a series.... not a model number.

Is this is what your motor sounds like..... it's time to replace it.

It isn't near as loud as the video you posted but it is definitely a similar sound at startup. I think I do need a new motor. Can anyone tell me what motor I need? I have family coming in this weekend and would prefer to get it fixed as soon as possible.
Thanks

Make sure you have the proper capacitor. The new motor will state what is required. It may be different than what you have and you may need to order one.

Sounds like a motor that's not coming up to speed to me---- is that right PJ Max?


IF thats the case and IF the motor has oil ports, it might be worthwhile to oil the motor, which might restore normal operation. However, some motors get damaged by lack of oiling and hard starting and still need to be replaced.

IF you want to give oiling a try, you often have to completely remove the motor from the fan housing in order to get to the inside oil port. If you aren't willing to do that, don't bother.


Of course, if you are going to replace the motor, you have to completely remove the motor anyway!

Taking pictures as you disassemble the fan will make it easier to rebuild the fan.

Yup... some very dried out bearings there. It's possible, but doubtful, lubrication will help at this point but you can't hurt anything to try it.

I found a motor with a local place that will honor the MFG warranty for 182. Seem reasonable? Gets me the motor quickly and supports a local shop. They also have the appropriate capacitor for 12 bucks.

Ok, a couple more questions.
The Motor I bought does not have as many wires as the original The original had 1 neutral and 4 other wires plus the 2 for the cap.
The new one has 1 neutral and 3 other wires plus the 2 for the cap.
When I wired the motor as suggested in the diagram it didn't work. I probed around with my meter and realized the output for the heat was the one wire that was missing from the new motor.
I moved the hi connector to heat and it is working ok now. I moved the mid hi wire to the cool and left low on low. Is this an appropriate configuration?

Also in the process of rewiring the AC red wire came out of the terminal it was connected to. Do you know where the AC not common should go? I think this is the 24V to the AC contactor? I didn't measure 24V on any other wires except the power out to the thermostat.

Thanks again.

$182 isn't that bad. It's not an inexpensive motor.

The two wires to the A/C contactor would connect to C and Y.

You should set the heat to mid-hi and the A/C to high.
