Noisy Trane XE 1000 outdoor compressor
 
Often I'll hear a loud whining coming from my Trane XE1000 compressor outside. Maybe bearing noise?

This is a heater pump with the "auxiliary" stage. Btw, my last electric bill was $350 and I used 1000 killowatts more than I did last year for this month.

Anyways, my limited research shows that replacing the fan compressor in the outdoor unit may resolve the noise problem.

I'm fairly mechanical and love DIY stuff. I just need to know of this will be as simple as shutting off the breaker at the compressor outside and doing a simple swap with the unit that Grainger will sell me?

Or will I have to mess around with refrigerant lines? That would be something I'd prefer to leave to a professional.

Thanks for any suggestions!

Btw, I'd like to also clean the unit while I'm doing this. I'll search the board for info on that.

Here are pics of the unit in case anyone is interested.

First day I moved into the house... yes those lighter fluid bottles below were removed immediately after taking this pic.

Are you sure it isn't your reversing valve making the noise.
Usually if its a fan motor. It will make the noise all the time.

No, I'm not certain. Other than consistency of noise, is there a good troubleshooting method to be certain which is the culprit?

The noise is not constant every moment the fan is on. It comes and goes. I haven't paid attention to exactly when it comes on. But when it is screetching/whining, it usually is like that for several minutes.

Btw I do use the auxiliary heat quite a bit. I hate being cold.

Go outside and see if its in defrost while making the noise. If it is. Then the fan won't be running, and you'll know its not the fan.

Thanks, beenthere. I just noticed the high pitched sound again. So I checked my thermostat and it was in normal operating mode (not aux). I then walked outside and see that the fan is spinning.

I took a short video so folks could hear the noise. Much of what you hear is the normal "rushing" sound of the fan spinning. But you can also hear the high pitched sound that has me concerned.

Here's the video:

Sounds a bit like blow by in the compressor.
is the large line hot while its running.

CZ DIY 02-07-2010 11:47 AM

Right at the moment, aux is on. The whine is gone. And yes, the large line is too hot to touch for more than a few moments.

CZ DIY 02-07-2010 11:49 AM

Whoop, the aux shut off and the whine is back. The top line is still pretty warm.

Check your indoor coil. Could be too dirty.

Thanks again. :)

To my inexperienced eye, it looks fine. But I don't know what to look for.

Would you recommend a foaming spray-on cleaner or mixed-solution cleaner & brush? I'll ask Home Depot on my way home from work tomorrow. Or is there a preferred solution for sale somewhere on the Internet?

I'll plan to do the indoor & outdoor cleaning next weekend!!

Bottom side of the coil is what you need to look at.

Naaah, still looks clean. ;)

I'm kind of nervous to realize just how bad that looks. The air I breath passes through this!!

I'm going to break out the shop vac right now and brush some of this off. Then I'll do the chemical cleaning next weekend as planned.

CZ DIY 02-07-2010 02:39 PM

I just noticed I have a full thing of CLR (Calcium, Lime & Rust remover). Can I use this to clean the coil with? I just can't go driving to Home Depot right now because I've already started drinking for the superbowl today.

Also have some Jomax.

Marty S. 02-07-2010 02:48 PM

CLR might eat the aluminum,don't know for sure though. A soft hair brush will get that off.
