Way to test whether pump or thermostat?

WeatherMaker Infinity. In the past the condensation pump has failed twice and the thermostat once. I troubleshooted by just swapping out parts. Is there an easier way?

Don't have a problem now. Just trying to learn for future reference.

You can bypass a float switch in a condensate pump to see if it has locked out operation but I usually just clean the reservoir and blow out the drain line output.

If your Infinity furnace has an Infinity thermostat you can connect the connect the float switch to R and G and configure the thermostat to monitor these terminals as a float switch.
