Short to Ground (Pinakabasic at usual na na test)
Ang compressor ay may tatlong winding terminals (T1, T2, at T3).
1) First, disconnect power supply for the compressor
2) Now, with multimeter, set to Ohms reading. One test probe to the body / housing and the other one to any of the winding terminals. Dapat lalabas ay 0 ohms. Pag may reading 0.0 ohms, ibig sabihin, damaged na ang winding at may part na nadidikit sa housing ng compressor
Example:
1) Ground to T1 : 1.39 ohms
2) Ground to T2: 2.45 ohms
3) Ground to T3: 3.23 ohms
Sa tatlong results, lahat lumabas n grounded na, Kasi may nababasang Ohms kahit walang power supply.
2) Continuity Test - Iset Ang multimeter sa continuity setting. Icheck ang continuity sa mga winding terminals. Kung lahat ng testing ay 0.0, ibig sabihin sira ang compressor.
T1-T2: 0
T2-T3: 0
T3-T1: 0
Pag ganito Ang results, siguradong sira Ang compressor.
