    Need advice on problem with apartment a/c....

    Got a problem with my apartment a/c and the maintenance guys can not seem to figure it out. Just looking for any ideas for them.

    It has the electronic thermostat and I set it at 75 year around "hold temp".

    Problem started last week, the inside fan unit shuts down leaving the outside unit running, and then inside fan turns on every once in a while, but the outside unit runs the whole time, and the lines form ice on them.

    They tested voltage, and checked freon, and did a boost charge on it, then replaced the inside fan, and still the problem continues.

    When I got home from work today, they said they could not recreate the problem and everything tests ok.

    It just did it again, and the outside ran for 40 minutes without the inside fan, so I just went ahead and shut the entire system down on the thermostat.

    Any advice, the maintenance guys are HVAC licensed, but they say that there is nothing they can do, because when they check it, it seems to be ok.

    Thanks,

    Replace the indoor blower motor and capacitor. The motor is heating up after running for a long time and going off on thermal overload in all likelihood. It's possible there's a control board issue but I'd do the motor as the most common failure of that type.
    If YOU want change, YOU have to first change.

    If you are waiting for the 'other guy' to change first, just remember, you're the 'other guy's' other guy. To continue to expect real change when you keep acting the same way as always, is folly. Won't happen. Real change will only happen when a majority of the people change the way they vote!

    Fill up your fridge with beer, make sure you have PPV available, and tell them to stay there till it happens again.....and hope it happens pretty quick!

    How many times must one fix something before it is fixed?

    What does the indoor fan do when you set the fan to the 'fan on' position at the thermostat? Does it turn on every time, or just sometimes?

    If it is a Goodman or a Janitrol I have a good idea of what the problem most likely is.

    Problem is the thing never seems to act up when they are here until after hours, and by time they get here it's running again. They spent an hour with it this morning while I was at work and it was fine the whole time, damn thing makes me look like a liar to them.

    He said there is no protection on the fan motor, that if it heats up, it would just burn out and stop working. I'll have to look around to see what brand it is, as it's all built into the ceiling and wall.

    Seems to me it would have a temp sensor and the motor is over heating, then starts running again when it cools down, like you guys have posted.

    I plan to keep calling the emergency maintenance number everytime it does it, so at least it's documented.

    They ordered a new outside compressor, saying that they would at least have that available if that is the problem, but they don't seem to really know.

    when something is bad you spank it...before you start replacing parts you have to figure out whats causing the problem

    In this case, if it is what I think it might be, then yes it would be because it is a Goodman.

    I'm not one to brand bash, but I have repaired several Goodman air handlers that had issues with intermittent fan operation, and it was not the thermostat that was at fault.

    "They ordered a new outside compressor, saying that they would at least have that available if that is the problem, but they don't seem to really know.

    They admit they dont know. They probably dont even know much about HVAC. It is a very simple problem to troubleshoot. Just stand there looking at it , aint gonna give them any clues. "they" need a new line of work.
    I'll be there when I get there and not a minute later

    First, the blower motor does have thermal protection. Its internal.
