heat pump and copper tubes to air handler
About a month ago we had problem with one of our heat pumps. It was
blowing hot air. They replaced the thermostat (it was calling for emergency heat when it shouldn't), the compressor motor and a capacitor. Now it is not working correctly again. It doesn't seem to be blowing hot air, but it isn't cool. Sometimes the compressor is running but the fan on it is not running. On the air handler there are two copper tubes. Sometimes the larger one is cool (and wet), other times it is room temperature. The smaller copper tube is hot. Does this mean it is calling for emergency heat again? Or what could be the problem? -- Replace you know what by j to email |

I left it off for a few minutes then turned it back on and now the compressor fan is blowing, it is blowing out warm air, it is blowing out cool air inside, the larger copper tube is cold and wet, and the small copper tube is at room temp or perhaps a little warm. (The small tube was pretty hot before.) -- Replace you know what by j to email |

The "small tube" (liquid line) being hot would most likely indicate that
the condenser fan motor shut off and the compressor stayed running. It could be a praoblem with the motor itself, or a problem in the defrost controls. What is the brand and model nuber of the unit? Larry |

I'm thinking you're not getting good service with this company. If they've replaced the wall thermostat, the compressor, the run capacitor, the outdoor fan motor, and you're still having issues - there's something rotten in your town and it's not the fruit. They didn't replace the compressor. The thermostat seems to have gone bad after an electrical storm and was telling the heat strips to come on when they shouldn't. But otherwise I think you are right. After I leave it off for a while, it will work for a while, but then the compressor fan stops turning again. -- Replace you know what by j to email |

Please shut the unit down. Compressor NEEDS the big fan to remove the heat,
you are at risk of compressor overheat and failure. Expensive. Call around, find a HVAC technician who knows heat pumps. -- Christopher A. Young Learn more about Jesus www.lds.org ..

That is happening. The compressor is running, but the fan isn't blowing. I can feel warm air coming out of the compressor, but the fan isn't blowing it out. could be a problem with the motor itself, or a problem in the defrost controls. What is the brand and model nuber of the unit? The motor was replaced last month. However, the new motor made a lot more noise than the old one. It is a Rheem RPKA-031, about 7 years old.
