• So to make a long story short i am haveing problems with the installation of the carrier infinity thermostat. Ive checked all my wires for continuity. I also have ABCD wires hooked up correctly. When the monitor goes into its plug and play state it searches for the equipment and can not communicate with it. I tried to call Carrier Tech assistance and they told me to call back monday. I really dont want to leave my customers without heat so if anyone has any ideas please let me know. Thanks in advance.


  • We install Lennox and Carrier. Both are very, very good. You can have a bad unit in ANY make. More importantly, it's the installers and techs that are ignorant to the correct operation that cause 95% of the problems. Properly trained technicians for ANY brand may ocassionally have a problem. We've found that factory tech support is excellent in all cases. But have an incompetent tech call and he's still lost when it comes to solving problems.

    Find a excellent company and you'll be happy with any brand.


  • your first mistake is that you used Carrier any thing, you can trust in Lennox and Trane.

    I have worked for all 3, I no longer call any of them!:thumbup2: Learned my lesson.


  • To bypass the Infinity stat, disconnect the plug at the furnace circuit board and install a conventional thermostat.

    What is wrong with them?
    I am looking to replace my York. Looking at Trane, Carrier and Amana. 16 to 18 SEER Heatpump.
