pag puno na ng alikabok ang evaporator, it acts as an insulator, at hindi ma-absorb ng hangin ang lamig (also the fact na hindi makadaan ang hangin), so the moisture around the tubes starts to ice up.
actually, all you need is water with adequate pressure to clean them. merong \"chemical solution\" talaga for cleaning, but frequent use also \"thins\" the aluminum evaporator (yung sa harap mismo ng aircon), at baka madaling magkaroon ng leak.
if for some reason, \"oily\" ang dumi sa evaporator, then use a household detergent. ganda pa nga gamitin ang \"JOY\" liquid, kasi walang naiiwang residue.
tama ring takpan ng plastic (kahit anong pwedeng ibalot) ang motor, para hindi mabasa ang bearings. ingat din sa pag linis sa evaporator kasi baka mabasa ang controls. some new models have electronic components inside, so extra care when using a hose.<br><br>Post edited by: Bien, at: 2007/06/17 13:33
