    Lennox G71MPP - calibrating for hours



    Lennox dealers who do you call for tech support? been on hold for 30+ min for the 4th time trying to reach someone. the worst tech support for a manufacturer.

    has anyone dealt with this calibrating issue? thermostat is the Honeywell IAQ.

    any help appreciated.
    thanks

    Are you registered with Lennox? If your phone number isn't you get put at the back of the list. Dealers get first in line.

    But yeah, the wait times suck some days. But when you get through they really are helpful.

    The board will not fix your problem. Calibration mode ramps to close the hi r low switch first, then the switch needs to open correctly then it ramps to close and reopen the other switch. Either you have defective presure switches or plugged ports off the collector box
