A two speed fan will say it's 2 speed. The brown wires you reference does not indicate how many speeds a motor has.

Controls can dictate how or when a fan turns on as well as off especially on a heat pump. If you don't understand operation, you're best to leave it alone and call a professional.

Just curious, how much did he charge you for the two speed fan motor and capacitor? It would seem to me you would not be having these issues if he installed the correct parts.

IMO

It would seem to me you would not be having these issues if he installed the correct parts.

ah another blanket statement to soothe your fears from a keyboard warrior. We have no idea how old the equipment is in question. All we can do is assume this or that, when the OP has demonstrated he has no real knowledge how or what this equipment is supposed to do during certain sequences of operation. It's a heat pump for God sakes.

If the unit is older, the fan motor was replaced one year doesn't mean the system will then operate without 'something else' breaking on most likely an older heat pump system.

The fan was replaced a year or so ago... the tech or who ever had to come back because they improperly attached it. Does this mean it's the wrong fan? no. While I wouldn't make a newbie mistake like that doesn't mean much.

After that the unit ran for a year, until further problems developed. It's an older unit most likely. Because fan motors can operate a long time before they ultimately fail.... do some fail prematurely? Yes. But it's not that common.

Old units break, it's what they do. Certainly if the unit was repaired improperly that could cause further issues, but this unit was probably older already because the OP never said anything about this part being under warranty from the manufacturer.

a garbage post from this forum's know-it-all...beware of an expert like that...it might help to have the brand, age, model, and serial number to verify the correct replacement fan motor and capacitor.

Beware of a 'so called' expert who doesn't provide service at all. Doesn't repair anything... just types nonsense in a forum board. Let's pretend we know what we are talking about.

I also 'know' you won't get service from a keyboard warrior. You only get 'SERVICE' from a pro.

Nothing else is going to keep your AC system running.

Yeah you certainly don't want a 'know it all' call someone with no experience at all.

Have fun!

The bigger problem is the young tech doesn't know how to wire a 2 speed motor for a one speed application. Leaving a capacitor, assuming it is the correct size, unsecured is sloppy workmanship.

My advice is to hire someone else who can assess the situation correctly in person and determine what changes need to be made.

We still don't know that this motor is a 2 speed motor. Nor do we know this unit is a one speed application. No proof has been given to identify anything. So everyone wants to play psychic?

Step right up want to take a guess?

Two brown wires from the motor to a capacitor does not indicate how many speeds a motor has or doesn't have.

A capacitor different from what was originally installed does not make a motor increase in number of speeds available.

Let's not pay attention to any facts at all --- let's guess.

You all are worse than the tech who couldn't wire it.

"The tech replaced my 1 speed motor with a 2 speed."

The model numbers of the heat pump and motor will confirm the number of speeds.

Mike that doesn't make it a 2 speed motor.

This is a facts based business. Anyone, including you can say anything they want.

Hearsay is never considered fact.

Ray,

If the homeowner could provide the model numbers, I would attempt to locate the wiring diagram of the heat pump to try to figure out how the original motor was wired. In some wiring diagrams the color of the wires are indicated which could help determine how the "brown" wire was connected on the original motor. I would also try to use the model number of the new motor to understand how it could be wired. I would also try to determine if the correct sized capacitors were installed. If they were not this new motor will have a short life. I may not be successful, but I like to help people as best I can when they ask these types of questions.

Any other facts I should be asking in order to guide the homeowner on what he should do next?

Mike, part of what I do here is guess. But it's an educated guess based on nearly 25 years professional experience as of July 2019.

Brown wires on a fan motor are for what? (hint, not related to speeds of a motor.) Realize this is edumacated.

In addition to that --- a two speed motor could be used, but hooked up only to run in the speed needed. We don't know any of that. It's pointless to speculate.

HVAC isn't a good idea to 'play' around with. So given the clues that this homeowner is not knowledgeable in knowing how this system operates (fan depending on mode of the heat pump can come on at a moments notice) that spells danger doesn't it?

It's not worth losing a finger over --- or possibly worse... call a professional. That's what we are here for.

Exactly the reason why I recommended he call a professional.

Safety first... ALWAYS!

When it comes to wiring I don't like to take guesses. I find it is more productive to locate the wiring diagram using the model numbers.

I agree this homeowner should not be making his own repairs. I was attempting to offer some guidance based on the facts I could gather.
