I called ASAP Appliance Repair Services to book me an appointment with the technician because our refrigerator was not cooling. The technician came on time and told me the coils were clogged, that's why it caused poor cooling. He made sure nothing was stuck in the condenser fan and that it spins freely. He then unplugged and pulled it out. He made sure the fan runs when the compressor is running. Later that day, he finally fixed our refrigerator! It is cooling perfectly now.
