Big thanks to Bobby for finding me one, saved me hundreds over new. Old EcoPlus model has a bad fan motor. I've contacted customer support to see if I can buy a replacement but would appreciate any info any of you might have on how to get one. Thanks
After further disassembly I found the reason it has made such a racket ever since i bought it when Brett was President. Two bad bearings, one completely frozen. Ten pack ordered from Amozon for $10, will be here Thursday and I expect a fully functional 1/10 HP chiller spare soon after.
If a mod reads this perhaps you could move to DIY. Thanks.
