Question about Frigidaire FAM157S1A Air Conditioner
Ok, so my husband drills 2 drain holes in it & hits a Freon line. AC guy comes out and sauders the line. He also had to install a Schrader valve & installed 23.? of Freon & vaccumed the line. Last summer the unit would freeze up on very hot days. We've had the power cord replaced a couple of years ago. Anyways, when you first turn it on, it's blowing ice cold but then a slightly different humming noise will happen about 7-10 minutes after it's on. Then, the air becomes warmer and more humid. There is NO water dripping outside either. Please help. I've been online all day trying to figure out what's wrong with no luck. Thanks
Sounds like it is either low on Freon or the compressor is going out. The blowing ice cold is an indicator that it may be freezing up because the low Freon. when it stops blowing cold, turn it to fan only mode and see if it gets colder again. If that is the case then the unit is low on freon and freezing up. I know that sounds confusing but that is how AC works. The low freon pressure means the gas is expanding too fast and the air flow cannot take up the cold from the evaporator fast enough. Turning the compressor off and keeping the fan on will alow the room air to take up the cold.

If compressor is tripping on overload it may be overcharged but it wouldn't blow cold very long. The hum you are hearing is probably a fan or compressor trying to run eventually overheating and tripping out. If he put too much freon in the system the outdoor unit would run for a while but get really hot making the compressor overheat. Try to go outside and see what's going on when it does this

These are designed to retain some water in the pan. This is for the slinger fan to throw water through the condensing coil. This helps the refrigerant cool and is important to the efficiency of the unit. I would certainly not recommend drilling a hole in the bottom. The hole may cause the water to roll somewhere where damage could occur. Try instead tipping the unit Backwards before bringing it in the house.

SOURCE: hums and freezes up????
The fan motor must have been stopping. If the fan stops, for sure the fins will freeze because there is no air flowing. common Fan motor problems defective bearing or bushing and starting condenser. If the bearing is defective, it will heat up and seize. Have the fan motor checked. The fact that the fins are freezing, means that there is enough freon and the compressor is working.

The compressor is stopping on overload. There is either a weak breaker or an electrical problem causing the overload to open the circuit and stop the compressor. It has to be taken apart to determine what is or is not going on.
