    Amana hi efficiency furnace
    I have Amana hi efficiency furnace. For some reason when furnace is working it works only for about five minutes and than it shows the code that the furnace is overheated. So it runs for 5 minutes and than cool down for 10. Imagine what it takes to heat the house.
    Changing the filters on a regular bases, have enough return air. Have no idea what could be the problem.
    Please help

    I will compare this info with the Amana schedule I have
