Refrigerator evaporator fan not working

Post by Lenaren on Tue Jan 03, 2017 3:35 pm

Hello sa master dito..

Happy new year po.. Hingi po sana akong tulong sa inyo.. May inaayos po kasi akong refrigerator ng coca cola... Di po gumagana yung evaporator fan.. nung check ko yung supply putok po yung fuse (3.15 amp) nya.. akala ko fuse lang.. nung pinalitan ko yung fuse sumabog ulit kasama yung NTC at dalawang diode.. ano kaya ung dahilan bat pumuputok ang fuse? 



Yung A po yun ung papuntang fan tapos yung B yung supply..

Inputs please..

Thanks...

pwde yan sis.. wag mo munang e load ang mga Loads = (A) Efan / Motor... para ma isolate mo ng Tama...

direct replace muna ang mga shorted rectifier diode, line thermal fuse (NTC), busted glass fuse.. pag hindi pumutok ang mga parts na yan ulit ay may problema ang efan mo...

Pwede gamit ka ng light bulb trick sis..baka may sayad ang pwm yan..kutob ko lang..sundin mo si sis ultra, isolate muna..pero pag pumutok parin baka problemado yung board...mas mainam parin mag light bulb trick baka may iba pang shorted..

Ok na iyan... pag pumutok pa rin iyan ay hatol ko dyan ay may sayad ang Fan Motor mo or ano mang Load nakalagay dyan... kung fan man iyan ay needed to rewind na iyan.. 

abwt sa thermistor..

eto data nyan:



SCK- mean NTC Surge Current Killer
053 - 5ohm 3A
201 - 20 ohm 1A
