[MBZ] OT: Hot out!
A couple weeks ago I bought a Haier HPN10XCM roll-around 10,000 BTU air conditioner at a yard sale, for $25. (This was approximately a $4–500 unit when it was new.) It was claimed to be working, but noisy. (I had intended it for my son's room, which gets very hot due to the afternoon sun and the fact that his computer, a MacPro 2,1 running Windows 10, can't go to sleep and wake up again, so it's usually always on—24×7. However, he showed absolutely no interest in using it to tame the heat in his room.) Yesterday it was very hot, the third or fourth 100+ degree day in a row, so I fired it up in the living room where the swamp cooler just can't reach effectively. Yes, it's noisy indeed! But it cooled well. Very smoky (stale) smelling, though, it could use a thorough cleaning. I opened it up. The plastic squirrel-cage blower on the condensor was severely out of balance, and had numerous blades that had broken loose from the free end's ring. It wobbled fiercely, enough to have developed a crack in the housing where the fan motor attached, exacerbating the noise and vibration problem. I used Shoe Goo to glue back 20+ fan blades to the ring, and to pot over the housing cracks. I also noticed that the fan always settled at the same point when spun by hand, rocking backwards if necessary, so the static balance was clearly off. I deposited Shoe Goo in layers on the light side of the fan's free-end ring, until the fan, when spun, would stop and stay stopped at random positions, indicating that the static balance was now pretty close to optimal. Once it had dried some I fired it up again, briefly, and noted that the noise and vibration were much reduced. Success? I'm going to let it cure thoroughly overnight. The condenser was also heavily coated with dust bunnies and pet hair, which I removed. I straightened some bent fins on the evaporator. After the glue had all dried thoroughly I ran the unit. Much quieter! So far it's holding the (now-sequestered) living room at 71 degrees. -- Jim ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
