Checking Capacitor Under Load. HVAC How to test a capacitor under load YouTube Another popular test many technicians use is the "under load capacitance calculation." Using this method on maintenance calls pretty much eliminates failed dual capacitor service calls for our maintenance customers

Now, set your meter to volts and take a reading across the capacitor that will give you the back electromotive force of the motor; note the reading Always double-check your math before you quote a customer

When you're constantly checking capacitors as a matter of regular testing and maintenance, testing the capacitors under load (while running) is a great way to confirm the capacitor is doing its job under real load. Set your clamp meter to amps and take an amp draw reading of the motor start winding wire connected to the capacitor, and note the reading Another Example; if the capacitor is rated 45/5 mfd, an allowable tolerance range for our example is 49.5 mfd - 40.5 mfd
