i cleaned evaporator and condensing coil with water yesterday to get ready for summer. today i turned on ac and a noise and smoke came from the compressor unit, I switched off the main line.hissing noise kept on coming for a while and it went away. could you please advice what could be the problem. I have carrier unit with carlyle compressor. model number GC06YF003.
Thank you so much for your reply. Could you please tell me what do I have to do to fix it. Is it something I can do it on my own. I appreciate your help.
Had an old Amana blow a compressor terminal right out of the casing. All the freon turned into phosgene gas and almost killed me. He may have a dead short to ground/winding shot. Need a tech to find out.
Sounds like the compressor terminals got wet during washdown and when you started it up it blew out one of the terminals which caused the freon to leak out and make the hissing sound until it was empty. Proably need a new unit.
I may save someone's life with this story. Arrived at service call and found condensor fan spinning slowly. Could be a bad motor/capacitor etc. Go to shut off disconnect at unit, Sumb*tch had none. Compressor not running. Go inside to shut off breaker, lights in house dim and hear this funny whistling noise. Run outside and hear compressor try start, loud whooshing noise, burning smell and then huge cloud of phosgene gas. Compressor had "single phase scenario". One winding broken and touching the housing which made a complete electrical path to ground for the few seconds it took to overamp and blow out the terminals etc. Point being that if I would have touched the condensor I would be dead. Breaker tripped shortly. If you ever see a slow moving condensor fan be careful as these cheap single pole contactors will allow a circuit thru one side and allow this too happen. The double pole are more safe but no one uses them.
Call a HVAC tech and have him look at it and just give him a discription of what happened do not try to go in to detail.
It's hard on line to know what exactly what happened.
The internal relief could have opened if the outdoor fan did not come on and you would see some smoke from the water on the unit getting hot, however if the internal relief did open it will reset itself if the fan works properly and the unit don't overheat. The circuit breaker concerns me.
Thank you so much for your feedback and I really appreciate it.
I do not think the fan came on. I switched on AC and went out to see if the fan is working. From the distance I heard the short circuit noise (bang) and saw smoke and I switched the breaker off. I went back to the unit and heard the hissing noise which lasted for a while.I did not smell any kind of gas tough.
The tech came and told me that the unit has to be replaced. i have carlyle scroll compressor. the round area where the wires are connected to the compressor is burnt.
You may also have a contaminated system if it ran and the burnt out windings etc got circulated into the rest of the system. Need proper flushing,testing and filter driers etc. If it is less than 13 SEER I would recommend a complete new system. Burn outs are very difficult to clean up properly.
