Operation Testing

Safety Precautions

Disconnect all power sources before servicing or installing

Preparation

Remove unit wiring from disconnect switch

Wire a test cord to the disconnect switch

Testing Setup

Ensure protective terminal cover is in place

Connect the common, start, and run clips to the respective leads on the compressor terminals

Connect good capacitors of the right MFD and voltage rating into the circuit

Run this procedure

Capacitance Check

Safety Precautions

Discharge capacitor through a 20 to 30 OHM resistor before handling

Measurement

Enter the amperage reading

Enter the voltage reading

Calculation

Calculate the capacitance (MFD) using the formula: 2650 X Amperage / Voltage

Run this procedure

Expansion Valve Operation Check

Remove the remote bulb of the expansion valve from the suction line

Start the system and cool the bulb in a container of ice water

Observe the suction pressure and temperature while cooling the bulb

Enter the suction pressure while cooling the bulb

Enter the suction temperature while cooling the bulb

Warm the bulb in your hand

Observe the suction pressure and temperature while warming the bulb

Enter the suction pressure while warming the bulb

Enter the suction temperature while warming the bulb

Run this procedure

Defrost Control Testing

Legacy Models

Ensure power is ON and unit is not running

Jumper defrost thermostat by placing a jumper wire across the terminals 'DFT' and 'R'/'R-DFT' at defrost control board

Connect jumper across test pins on defrost control board

Set thermostat to call for heating. System should go into defrost within 21 seconds

Immediately remove jumper from test pins

Check for voltage across terminals 'C & O'. Meter should read 24 volts

Check for voltage across fan terminals DF1 and DF2 on the board. You should read line voltage (208-230 VAC) indicating the relay is open in the defrost mode

Check for voltage across 'W'/'W2' & 'C' terminals on the board. You should read 24 volts

Run this procedure

Capacitor Check

Run Capacitor Inspection

Verify the wiring of the run capacitor

Is the capacitor reducing line current and improving torque characteristics?

Start Capacitor and Scroll Compressor Check

Is a hard start kit installed?

Verify the hard start kit

Is the discharge check valve functioning properly?

Is the Time Delay Relay (Cycle Protector) installed in the low voltage circuit?

Start Relay Inspection
