1. Tinofanira kusiyanisa kana simba rekushanda refiriji compressor rakasimba.Kana iyo AC contactor yakabatana nefiriji compressor isingadhonze mukati, iyo yekuchinjisa magetsi eiyo yepamusoro uye yakaderera tembiricha bvunzo bhokisi haigone kuve yakavakirwa pane izvi.Iko kune zvakare kana tambo yefiriji compressor yakabatana nepamusoro uye yakaderera tembiricha bvunzo bhokisi yakatyoka kana isina kubatana.Mamwe akakwira uye akadzika tembiricha ekuyedza makamuri achiri ane mamwe mapfupi edunhu kukanganisa panguva yese yekufambisa.Wobva wasiyanisa kana iyo yakayerwa inoshanda voltage inosangana nezvinodiwa.
2. Izvo zvinodiwa kuti nyanzvi dzisiyanise mwero wezvino wefiriji compressor mukamuri yepamusoro uye yakaderera tembiricha yekuyedza.Ese mazinga azvino anofanirwa kuyerwa voltage yefiriji compressor vasati vashanda zvakajairwa.Kana iyo voltage yekushanda yakajairika, mari iripo haina kutaurwa , Ipapo inoratidza kushaikwa kwefiriji.
3. Tarisa uone kana feni yekupisa yekupisa yepamusoro uye yakaderera tembiricha test box iri mukushanda kwakajairika.Pasi pemamiriro ekushanda, mhepo yemhepo inofanira kunge yakagadzikana, mhepo inofanira kuva yakafanana uye pombi yemhepo inofanira kuva yakarurama.Kune zvakare nzira yekugomera tembiricha yepombi yekupedza yefiriji compressor.Tembiricha yakajairika yekumusoro uye yakaderera tembiricha yekamuri yekuyedza yakakwira kupfuura tembiricha yakajairwa, setembiricha yekunze kwekunze kwemhepo yekupisa fan yakakwira.Tarisa uone kana iyo inotenderera system centrifugal fan iri mukamuri iri mukushanda kwakajairika.Kana iyo isiri kushanda mushure mekupisa, iyo air conditioner evaporator haigoni kuputika kazhinji, kuitira kuti kutonhora kurege kuderedzwa.
