Be certain that the thermostat is ready to COOL and its temperature setting is no less than three levels under the ambient room temperature. 3. Be certain that the ability is on. Examine the swap within the furnace or air handler, and the outside condenser. Additionally be certain the compressor’s 240-volt disconnect, sometimes in a steel field mounted close to the compressor, hasn’t been shut off. With any such digital thermostat, you pull off the physique to entry the baseplate and wires. 4. Take away the thermostat’s cowl after turning off the ability to the air conditioner.

Earlier than opening {the electrical} cowl on the A/C unit, make sure you shut off all energy to the unit and confirm that it’s off. Take away the duvet and, utilizing a digital multi meter set to “Capacitance,” put one lead on the “Frequent” terminal and the opposite lead on one of many different two terminals. The meter ought to present a quantity—not “OL” which signifies a brief. A/C capacitors may be like two capacitors in a single, with each sharing the widespread leg.
