Hello, the central air thermostat in the House is showing that the air-conditioning is on, but the outside unit is not running or kicking on?

Is indoor unit running? And do you have a meter for troubleshooting?
Customer: replied 2 years ago.
On the furnace the fan is set on-and it is running. But the outside unit is not running, and I do not have a meter
Expert:  airheatman replied 2 years ago.
PUT thermostat to COOL and Fan Auto and tell me if fan still runs inside.
Customer: replied 2 years ago.
Yes the fans still runs on auto setting
Expert:  airheatman replied 2 years ago.
OK now we are limited to what we can check without a meter.You can pick up an inexpensive one if you would like at Walmart. Lets check some visual things first. Look in your drain pipe coming from the evaporator and see if there is a float switch with 2 wires connected. If so, lift the switch out of the drain pipe and see if outdoor unit comes on.We will go from here.

OK I will give it a try

I located the drain pipe that comes out from the evaporator and did not see a float switch with two wires? The bottom drainpipe did have some standing water in it and I blew it out which was somewhat moldy. The outside unit still is not on. The unit is a Bryant furnace that was installed in 2001-not sure if that helps
Expert:  airheatman replied 2 years ago.
OK can you open the outdoor unit and look at a couple of things?
1. See if capacitor looks swollen or puffy:
