"Fuses keep blowing" It definitely wasn't the compressors, as they were disconnected, but I wanted to check them anyway. One compressor had electrically failed. The other compressor was okay electrically, but using the Testo North America 549i it was found to be out of refrigerant. The disconnect switch ended up being the culprit. #hvac #hvacr #hvacsystem #hvactraining #hvactroubleshooting #hvaceducation #HVACKnowledge #commercialHVACservice #hvacservice #hvacsservicecall | HVAC Know It All
