    Question

    We have an old lear/siegler central air unit. We just replaced the fan and it was working fine. All of a sudden the unit keeps blowing fuses and is not running. Can it be the condensor? If so, is it better to replace it or get a new central air unit? Someone said that to replace the condensor was extremely expensive. Any help would be appreciated! Victoria

    Could be the compressor is dead shorted to ground. If so, the best thing to do is to replace the entire system.

    Don't go the cheap route of only having the condenser changed unless you are moving within the year and don't care what problems the next owner might have.

    Just in case anyone is wondering;
    HOME FURNACE: Became Home Furnace division, Lear-Siegler Inc. Became Miller Heating & Air Conditioning in 1986 after being acquired by Nortek Inc. Now listed as Nordyne. See Intertherm.

    Also, could be a shorted or grounded run capacitor, or badly burnt terminals connectors, etc.

    Could be bad breakers, or wiring connections anywhere, or bad control contactor points, etc.

    Be there when they check it; some just love to tell you it is the compressor when it could be a low cost fix. - Darrell

    The last guy replaced the motor because the fan wasnt turning. Could it be that the motor isnt working right?

    Thanks for all the help!
