Hi there, i need your help
i'm working on refrigerator using r12 it's very old, the compressor using 3 in 1 relay, start capacitor and was run for for 3 mins then off for 7 mins and on for 3 mins again and again, But, both side fan is still runing only the compressor off and on, i checked superheat i got 36F and subcooled i got 31F and i also checked temp control it's working ok and nothing block the eaporator coil and the condenser coil, the onwer said he did replace the compressor 2 years ago...you think it's has restriction on the cap tube? or it's just low charge? but if low charge subcooled should be low right? or maybe 3 in 1 is bad? thank you vrey much for your help..
