Iisifudumezi sokucoca ulweloinyibilikisa umkhenkce kunye neqabaka eziqokelelene kwikhoyili ye-evaporator yefriji okanye ifriji. Umgaqo osebenzayo we-heater yokunyibilikisa kukufudumeza ikhoyili ye-evaporator, ukunyibilikisa umkhenkce kunye nokukhupha amanzi.into yokunyibilikisa i-heaterisetyenziselwa ukuthintela ifriji ukuba ingabi shushu kwaye ilawulwa yi-thermostat. Ngexesha lomjikelo wokunyibilikisa, isifudumezi esinyibilikisayo siyayinyibilikisa iqhwa elikwiiphiko ze-evaporator.
Izifudumezi ezinyibilikisa iqhwaziyimfuneko ekunyibilikiseni umkhenkce oqokelelene kwiikhoyili ze-evaporator zezixhobo zokukhenkcezisa zorhwebo. Xa umkhenkce uvela kwikhoyili ye-evaporator, unokonakalisa kakhulu umsebenzi wesixhobo sonke, nto leyo eyenza kubaluleke kakhulu ukugcina isifudumezi esinyibilikisayo sisebenza kakuhle kwifriji nakwifriji.
Ke ungafumanisa njani ukuba ityhubhu ye-defrost heater yonakele?
Eyonakeleyoityhubhu yesifutho sokucoca umkhenkceinokubangela ukwakheka komkhenkce ogqithisileyo kwi-evaporator coil, ngaloo ndlela inyusa ubushushu ngaphakathi kwifriji okanye kwifriji. Ungasebenzisa ne-multimeter ukuvavanya ukuhanjiswa kwayo kunye nokumelana kwayo, nto leyo eya kubonisa ukuba i-heater isebenza kakuhle na.
Iimpawu zomonakalo kwi-heater enyibilikisa iqhwa
1. Ukwakheka komkhenkce okugqithisileyo
Ukuba ufumanisa ukuba kukho umkhenkce omninzi kwi-evaporator coil kunesiqhelo, oku kungaba luphawu oluqinileyo lokubaisifudumezi sokucoca ifrijisele iza konakala.
2. Ukunyuka kobushushu
Ifriji okanye ifriji isenokuba ayifikanga kubushushu obuphantsi obulindelekileyo, okanye kusenokubakho ukuguquguquka kobushushu.
3. Umjikelo wokunyibilikisa iqhwa ngesandla
Ukuba uqala ngesandla umjikelo wokunyibilikisa i-frost kodwa i-heater ayitshisi, isenokuba yonakele.
4. Uvavanyo lokuqhuba
Sebenzisa i-multimeter, uyibeke kuluhlu lwe-ohm, uze ucinezele i-probe kwii-terminals ze-heater.
5. Ukuxhathisa:
I-heater efanelekileyo yokunyibilikisa kufuneka ibe nexabiso elithile lokuxhathisa, elihlala liphakathi kwe-20 ne-100 ohms. Ukuqhubekeka: Ukuba akukho ukuqhubeka (isixhobo sibonisa isekethe evulekileyo), i-heater ingonakalisa.
Ukuba ufumanisa ukubaisifudumezi esinyibilikisa iqhwaukuba yonakele, kufuneka itshintshwe. Ukutshintsha i-heater kunokuba ngumsebenzi olula we-DIY, kodwa kusoloko kuyinto entle ukujonga incwadi yemiyalelo okanye ukulungisa ividiyo yemodeli yakho ethile yefriji.
