Furnace/fan won't turn off
I have a chronotherm 3 thermostat, Lennox ECB19 12.59 furnace and a Lennox HP19-651-6d heat pump. The heat pump stopped working and then the furnace won't turn off, fan runs on high, I pushed the reset button on the heat pump where the blue wire is attached and now the heat pump work fine. But the furnace still won't stop running I have to turn it off at the braker in the house. I got a new thermostat and that didn't fix the problem. I replaced the three heat relays and I believe to be the blower/fan relay part#90-340 by white-rodgers. And still the fan won't turn off I also removed the green wire at the therm and it won't turn off any help would be apperacated.
