I changed out the condinsation pump and now the carrier Infinity Thermostat has not power, hence the AC will not turn on.

Model 58CVA090-16
Series 140

Have tried turning on and off and on the power to the unit and house.
Have tried pulling the thermostat off the wall and putting it back.
There is power to the AC (orange/yellow steady light).
The new pump works.
Help

Check that you reconnected the safety switch wires at the new condensate pump.
