It sounds like a bad blower motor. Is this a standard blower or an ECM motor?

How do I tell the difference?
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

A standard blower is shorter and has thicker wires. An ECM motor is longer and has thinner wires. Does your motor look similar to this?

its a 2009 unit
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

I must forewarn you, troubleshooting an ECM motor is much more complicated than troubleshooting a standard blower. If you want to attempt, I recommend you download the ECM service guide. This will guide you through the troubleshooting techniques. There are also many good videos on YouTube that talk about troubleshooting ECM Genteq motors. Such as this one.

If the motor is bad why would it still spin?
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

That is typical of an ECM motor when it starts to go bad.

Ask Your Own HVAC Question
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

But, as you can see, these motors are not cheap which is why I recommend troubleshooting first.

Ask Your Own HVAC Question
Customer reply replied 2 years ago
Any way to get it to spin enough to cool for the night?
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

Not that I'm aware of. A lot of times, the back part of the motor (called the module) goes bad. There are capacitors inside which can go bad.

HVAC Technician: Tim H., HVAC Professional replied 2 years ago

I wish I could offer an easy fix. The good news is if it's a 2009 model, it MAY be still under warranty, however, it would only be the part, not labor.

Customer reply replied 2 years ago
Well that was smart of the engineers, put the cheap easy to replace parts inside the expensive hard to replace part.
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

Yeah, I know. Although these motors save hundreds of dollars a year in electrical cost, the downside is when they go bad, they're expensive to replace.

I know for a number of years, Goodman units had a 10 year parts warranty. You may want to check your warranty.

Ask Your Own HVAC Question
Customer reply replied 2 years ago
who would I call to check on the warranty?
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

Your best bet is to call a local Goodcare dealer. These can be found on the website, dealer locator,

Customer reply replied 2 years ago
any other control modules or fan speed controlers that could be the issue?
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

I would also check the wiring to the motor. Make sure the wires are plugged in securely to the motor and board. It's usually motor that fails.

Ask Your Own HVAC Question
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

I have to leave for a bit for some service calls. Did you have any additional questions?

Ask Your Own HVAC Question
HVAC Technician: Tim H., HVAC Professional replied 2 years ago

One other simple check I thought of, you could go out and pick up a new thermostat if you have a cheap one or an older model. Since the thermostat is what sends the 24 volt signal to the air handler for blower to run, if it was bad, it may cause erratic operation. Again, I am not saying this is the problem, but could possibly be an issue.
