COMPONENT OPERATION AND TESTING  
WARNING  
COMPRESSOR WINDING TEST  
(See Figure 2.)  
Remove the compressor terminal box cover and  
disconnect the wires from the terminals. Using  
an ohmmeter, check continuity across the  
following:  
DISCONNECT ELECTRICAL POWER TO  
THE UNIT BEFORE SERVICING OR  
TESTING  
COMPRESSORS  
FIGURE 2 COMPRESSOR WINDING TEST  
Compressors are single phase, 208/230 volt. All  
compressor motors are permanent split capacitor  
type, using only a running capacitor across the  
start and run terminal.  
All compressors are internally spring mounted and  
externally mounted on rubber isolators.  
Line Voltage Overload  
Testing Procedures  
The compressor is equipped with an internal line  
voltage overload. This overload is embedded in  
the windings of the motor to sense the motor  
temperature. The overload will open and  
disconnect the power to the motor due to high  
temperatures caused by:  
1. Terminal "C" and "S" - no continuity -  
open winding - replace compressor.  
2. Terminal "C" and "R" - no continuity -  
open winding - replace compressor.  
3. Terminal "R" and "S" - no continuity  
open winding - replace compressor.  
1. A locked rotor.  
2. Excessive running amps.  
3. High discharge temperature.  
4. Low refrigerant charge.  
4. Terminal "C" and the shell of the  
compressor – continuity – grounded  
motor – replace compressor.  
5. Should continuity exist between  
terminals "R" and "S", but not between  
terminals "C" and "S" and "C" and "R",  
the internal overload may be open. If  
the compressor is extremely hot, allow  
it sufficient time to cool. It may require  
as long as one hour for the compressor  
to cool sufficiently for the internal  
overload to close.

GROUND TEST  
FAN MOTOR (Figure 4)  
Use an ohmmeter set on its highest scale. Touch  
one lead to the compressor body (clean point of  
contact, as a good connection is a must) and the  
other probe in turn to each compressor terminal.  
(See Figure 3.) If a reading is obtained, the  
compressor is grounded and must be replaced.  
A 230 volt single phase permanent split capacitor  
motor is used to drive the evaporator blower and  
condenser fan. A running capacitor is wired  
across the start and run terminals of the motor.  
The motor is totally enclosed and is protected with  
a line voltage overload located internally of the  
motor. The motor shaft is stainless steel to resist  
corrosion.  
FIGURE 3 TYPICAL GROUND TEST  
FIGURE 4 FAN MOTOR  
CHECKING COMPRESSOR EFFICIENCY  
The reason for compressor inefficiency is  
normally due to broken or damaged suction  
and/or discharge valves, reducing the ability of  
the compressor to pump refrigerant gas.  
FAN MOTOR – TEST  
Disconnect power to the unit.  
1. Determine that the capacitor is serviceable.  
2. Disconnect the black lead from the circuit  
board.  
3. Apply "live" test cord leads to the common  
terminal of the capacitor and the black lead.  
The motor should run at high speed.  
This condition can be checked as  
follows:  
1. Install a piercing valve on the suction and  
discharge or liquid process tube.  
2. Attach gages to the high and low sides of the  
system.  
3. Start the system and run a "cooling or  
heating performance test."  
If test shows:  
A. Below normal high side pressure.  
B. Above normal low side pressure.  
C. Low temperature difference across the coil.  
The compressor valves are faulty -  
replace the compressor.

SYSTEM CONTROL SWITCH  
(Figure 5)  
This switch is double pole, single throw. Check  
for continuity between terminals 2 and 3, and 5  
and 6.  
CAPACITOR – TEST  
1. Remove the capacitor from the unit.  
2. Check for visual damage such as bulges,  
cracks, or leaks.  
3. For dual rated capacitors, apply an ohmmeter  
lead to the common (C) terminal and the other  
probe to the compressor (HERM) terminal.  
A satisfactory capacitor will cause a deflection  
on the pointer, then gradually move back to  
infinity.  
FIGURE 5 SWITCH, ON-OFF  
4. Reverse the leads of the probe and  
momentarily touch the capacitor terminals.  
The deflection of the pointer should be two  
times that of the first check if the capacitor is  
good.  
CAPACITOR, RUN  
5. Repeat steps 3 and 4 to check the fan motor  
capacitor.  
A run capacitor is wired across the auxiliary and  
main winding of a single phase permanent split  
capacitor motor such as the compressor and fan  
motors. A single capacitor can be used for each  
motor or a dual rated capacitor can be used for  
both.  
NOTE: A shorted capacitor will indicate a low  
resistance and the pointer will move more  
to the 0end of the scale and remain there  
as long as the probes are connected. An  
open capacitor will show no movement of  
the pointer when placed across the terminals  
of the capacitor.  
The capacitor’s primary function is to reduce the THERMOSTAT  
line current while greatly improving the torque  
characteristics of a motor. The capacitor also A cross ambient

HERMETIC COMPONENT REPLACEMENT  
The following procedure applies when replacing  
components in the sealed refrigeration circuit or  
repairing refrigerant leaks. (Compressor,  
condenser, evaporator, capillary tube, refrigerant  
leaks, etc.)  
NOTE: This procedure can be speeded up by  
the use of heat lamps, or by breaking the  
vacuum with refrigerant or dry nitrogen at  
5,000 microns. Pressure system to 5 PSIG  
and leave in the system a minimum of 10  
minutes. Recover refrigerant, and proceed  
with evacuation to a pressure of 200 microns  
or a minimum of 10%.  
1. Recover the refrigerant from the system at the  
process tube located on the high side of the  
system by installing a line tap on the process  
tube. Apply the gauge from the process tube  
to EPA approved gauges from the process  
tube to the EPA approved recovery system.  
Recover the CFCs in the system to at least  
5%.  
11. Break the vacuum by charging the system  
from the high side with the correct amount of  
refrigerant specified. This will prevent boiling  
the oil out of the crankcase.  
NOTE: If the entire charge will not enter the  
high side, allow the remainder to enter the  
low side in small increments while operating  
the unit.  
2. Cut the process tube below the pinch off in  
the suction side of the compressor.  
12.Restart the unit several times after allowing  
pressures to stabilize. Pinch off the process  
tubes, cut and solder the ends. Remove the  
pinch off tool, and leak check the process tube  
ends.  
3. Connect the line from the nitrogen tank to the  
suction process tube.  
4. Drift dry nitrogen through the system and  
unsolder the more distant connection first.  
(Filter drier, high side process tube, etc.)  
SPECIAL PROCEDURES IN THE CASE OF  
COMPRESSOR MOTOR BURNOUT  
5. Replace the inoperative component, and  
always install a new filter drier. Drift dry  
nitrogen through the system when making  
these connections.  
1. Recover all refrigerant and oil from the system.  
2. Remove the compressor, capillary tube and  
filter drier from the system.  
6. Pressurize the system to 30 PSIG with proper  
refrigerant and boost the refrigerant pressure  
to 150 PSIG with dry nitrogen.  
3. Flush the evaporator, condenser and all  
connecting tubing with dry nitrogen, or  
equivalent, to remove all contamination from  
the system. Inspect the suction and discharge  
lines for carbon deposits. Remove and clean  
if necessary.  
7. Leak test the complete system with the electric  
halogen leak detector, correcting any leaks  
found.  
4. Reassemble the system, including a new drier-  
strainer and capillary tube.  
8. Reduce the system to zero gauge pressure.  
5. Proceed with processing as outlined under  
hermetic component replacement.  
9. Connect the vacuum pump to the high side  
and low side of the system with deep vacuum  
hoses, or copper tubing. (Do not use regular  
hoses.)

ROTARY COMPRESSOR SPECIAL  
TROUBLESHOOTING AND SERVICE  
REFRIGERANT CHARGE  
1. The refrigerant charge is extremely critical.  
Measure the charge carefully and as exactly  
as possible to the nameplate charge.  
Basically, troubleshooting and servicing rotary  
compressors is the same as on the  
reciprocating compressor with only a few  
exceptions.  
2. The correct method for charging the rotary is  
to introduce liquid refrigerant into the high side  
of the system with the unit off. Then start the  
compressor and enter the balance of the  
charge, gas only, into the low side.  
1. Because of the spinning motion of the rotary,  
the mounts are critical. If vibration is present,  
check the mounts carefully.  
2. The electrical terminals on the rotary are in a  
different order than the reciprocating  
compressors. The terminal markings are on  
the cover gasket. Use your wiring diagram to  
insure the correct connections.  
The introduction of liquid into the low side,  
without the use of a capillary tube, will cause  
damage to the discharge valve of the rotary  
compressor.  
NOTE:  
All inoperative compressors returned to  
Friedrich must have all lines properly plugged  
with the plugs from the replacement  
compressor.
