If it sounds like you're shaking a tin can with pennies bouncing in it ... it's done. ... the compressors in them are pretty expensive to replace. I looked into it for my old 1/2HP ... and all of the A/C companies wanted nearly as much for the new copeland compressor as I could buy a new chiller for ...

**EDIT** ... this was based on the 1/2 HP I had at one time ... By the time I paid for the service call, and paid to have the unit recharged .. i could've just bought a new one ...

It sounds to me like the fan motor is going bad. I'd say its pretty common for a undersized chiller to have this problem at about two years because i'm sure it runs more frequently than it normally would. Not sure what they run but i had to replace two on the chillers i had at the store when it was at the old location and we had no A/C out back. Its a pretty easy fix and if your pretty good with hand tools and common sense you can most likely fix it yourself. It shouldn't be more than a $100 for a new fan motor. Hope this helps.

Thanks to ALL that replied. I took it apart and gave the fan shaft/motor a shot of WD40 and now it's purring like a kitten.

I guess It wouldn't be a bad idea to give it a shot maybe once a month to keep it from drying out again.

Thanks again,

Steve

Glad thats all it was .. as far as WD40 ... I have something MUCH better ...

Go & locate a bottle of WURTH HHS2000 ... this stuff is the cats paw. It's a liquid spray that sets into a high temp grease ... it'll run into all the cracks & crevices, and about 5-15 seconds later it will set & quit running.
That is the ONLY thing i'll use to grease something ... this will hold up... very well and for quiet a while.

here is a link to a bottle on ebay:

defiantly need some lubercant that will last. WD 40 will nit last long at all. that stuff Marco is talking about is the stuff to use. I use to have some but I wonder if anyone around here local has it. The use to have it at Steego and Hoods a while ago.

Chris, where is this Steego & Hoods ? Is it an auto parts or hardware store?

Hey thanks for the link Marco.

both are by bill branch on fowler. hoods is for parts and steego is for bodywork supplys

Steve,

no problem. I purchased my bottle on ebay about ... 5-6 years ago. I'm still on the same bottle, even though this one is nearing the end. This stuff really is great. Never need alot of it, one quick spray & it runs into all the cracks ... lasts a LONG time.
