Weird Air Handler Blower Challenge For You

This is about a 4 year old Goodman Model ASPF426016BA. About 4 months ago the blower started failing to come up to speed. I heard it trying to start, but it would barely be spining and then drop out or run very, very slow for seconds at a time over and over again without kicking all the way up to normal speed. I left it alone for a day or two turned it back on and it ran normally up until the other day when the blower motor started faltering at start up again. Thermostat is doing it's thing and the compressor is working. I am looking for directions and the steps to take to diagnose and repair this myself. The motor runs perfect when it runs (no bearing issues or improper noise). It acts like an electrical issue. Some info on how these motors and controls work would be greatly appreciated. I want to do the repairs myself rather than pay a company the labor to change parts (parts are under warranty). I think it may be less expensive for me to pay for the parts and do the labor myself. Please weigh in...

Note: tried to upload pictures and video but it kept failing. Not sure I can get them uploaded... help?

First thing to check is the capacitor which is located somewhere near the blower or control board.

ASPF Motor
The ASPF air handler features an energy efficient blower motor. The motor is a constant torque motor with very low power consumption. The motor is energized by 24 VAC. Adjust the CFM by changing the 24 VAC leads to the desired speed on the terminal block. The ASPF motor blower speed is programmed to deliver adequate airflow at rated external static pressure and with 60
second off time delay.

Therefore hold on to your pants cause you're looking at an expensive motor. I don't see any capacitor to check..... actually not much of anything to check..... it's all in the motor.

Link to your manual.........

Your looking at about $400 for that motor.

Blower Motor

Right, the controls are all in the motor. Seems I've read somewhere that the controls in the motor can be replaced without replacing the motor itself. Also, what should it cost to have a company do the replacement, seems like that's cheaper than buying the whole motor assembly myself? It's obviously easy to replace. Any thoughts on just replacing the controls in the motor? Thanks soooo much!

Some motors can be worked on. You'd need to post the make and model of the motor you currently have. Replacement motors supersede old numbers and can be from different manufacturers. Is that a Genteq Eon motor ?

Blower Motor

Sorry, I'm trying to put a link to a video with sound so everyone can see and hear how the motor is acting but I'm having a hard time doing it.

Question: Would the sequencer/relay cause a blower problem like I've described previously?

How do I delete the previous post? I went to edit but there is no provision for deleting it.

You only have a limited time to edit your posts. An hour or two. I'll delete the post for you.

I don't think the sequencer would have anything to do with a motor problem.
