Question about Heating & Cooling
Hi, and no your warranty is not void due to a flooded disconnect box, this is a lie!! If both fans are running, and you have no heat or cooling, the compressor is not running. This is a heat-pump with a reversing valve. The indoor unit has a control circuit board that gets a signal from the thermostat to tell it what to do. The outdoor unit may have locked up due to the fact that it was going on and off, short cycling which could have locked it up. If your outdoor fan is on, the compressor should be on also as this is what pumps freon through the system to cool and heat. He may have unplugged something at the board, not knowing what he was doing. If you can, go to the outdoor unit. Have someone turn it on, and you listen to see if you can hear the compressor come on. It will hum, and continue to hum and smooth out as it gets up to speed. If you hear it hum and try to start and then stop right away, this compressor is locked up, has what is called a locked rotor. This maintenance guy needs to come out and check your run capacitor also. You can also check it by looking it over as if it is bad, the compressor will not start. If it only has one, a dual capacitor, it should be good if your outdoor fan is running, as it runs both the compressor and fan. You can do this, kill the main power and go to the outdoor unit. Look where the wiring come into the unit and remove this panel. You will see the capacitor mounted on the side, it could be round and about 4 to 6" tall with wire terminals coming out the top. Look it over to see if it is leaking oil, or the top is swollen up or deformed. If you see this, the compressor side is bad. You will need a new one. If it looks good, place your hand on top off the compressor if you have room to get to it. Turn the power on first and the thermostat off. If you can place your hand on it, have a helper turn the cooling on until the unit starts to see if the compressor starts. If you can't put your hand on it, you will be able to here to see if it came on or tried, and stopped. This will tell you its the compressor. DO NOT let them tell you that the box voided the warranty, this is a lie!! I know this for sure as I am a licensed contractor!! Get them out there and they can install a hard start kit to see if it will break this compressor loose, be sure you tell them this. It is a booster that sometimes will break loose a stuck compressor. Please keep me posted on this. Please don't forget to rate me as I know you will be kind.
