Basic test procedure
12
8 Basic test procedure
8.1 Defective compressor
Compressors are single phase, 115 or 230/208 volt, depending on the model unit. 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.
8.1.1 Compressor wiring test
Remove compressor terminal box cover and disconnect wires from terminals. Using an
ohmmeter, check continuity across the following:
Terminal "C" and "S" - no continuity
- Open winding - replace compressor.
Terminal "C" and "R" - no continuity
- Open winding - replace compressor.
Terminal "R" and "S" - no continuity
- Open winding - replace compressor.
8.1.2 Ground test
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 2.) If a reading is obtained, the compressor is grounded
and must be replaced.
8.1.3 Checking the 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.
This condition can be checked as follows:
1. Install a piercing valve on the suction and discharge or liquid process tube.
2. Attach gauges to the high and low sides of the system.

Basic test procedure
13
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 coil.
The compressor valves are faulty - replace the compressor.
8.1.4 Terminal overload (external)
Some compressors are equipped with an external overload which is located in the
compressor terminal box adjacent to the compressor body The overload is wired in series
with the common motor terminal. The overload senses both major amperage and
compressor temperature. High motor temperature or amperage heats the disc causing it to
open and break the circuit to the common motor terminal.
Heat generated within the compressor shell is usually due to:
1. High amperage.
2. Low refrigerant charge.
3. Frequent recycling.
4. Dirty condenser.
8.1.5 Terminal overload – Test (compressor external type)
1. Remove overload.
2. Allow time for overload to reset before attempting to test.
3. Apply ohmmeter probes to terminals on overload wires. There should be continuity
through the overload.
8.1.6 Terminal overload (internal)
Some model compressors are equipped with an internal overload. The overload is
embedded in the motor windings to sense the winding temperature and/or current draw.
The overload is connected in series with the common motor terminal.
Should the internal temperature and/or current draw become excessive; the contacts in the
overload will open, turning off the compressor? The overload will automatically reset, but
may require several hours before the heat is dissipated.
8.1.7 Checking the internal overload
1. With no power to unit, remove the leads from the compressor terminals.
2. Using an ohmmeter, test continuity between terminals C-S and C-R. If not continuous,
the compressor overload is open and the compressor must be replaced.
8.2 Sealed refrigeration system repairs
8.2.1 Equipment require
1. Voltmeter
2. Ammeter
3. Ohmmeter

Basic test procedure
14
4. E.P.A. Approved Refrigerant Recovery System.
5. Vacuum Pump (capable of 200 microns or less vacuum.)
6. Acetylene Welder
7. Electronic Halogen Leak Detector (G.E. Type H-6 or equivalent.)
8. Accurate refrigerant charge measuring device such as:
a. Balance Scales - 1/2 oz. accuracy
b. Charging Board - 1/2 oz. accuracy
9. High Pressure Gauge - (0 - 400 lbs.)
10. Low Pressure Gauge - (30 - 150 lbs.)
11. Vacuum Gauge - (0 - 1000 microns)
8.2.2 Equipment must be capable of:
1. Recovery CFC's as low as 5%.
2. Evacuation from both the high side and low side of the system simultaneously.
3. Introducing refrigerant charge into high side of the system.
4. Accurately weighing the refrigerant charge actually introduced into the system.
5. Facilities for flowing nitrogen through refrigeration tubing during all brazing processes.
8.2.3 Hermetic compressor replacement.
The following procedure applies when replacing components in the sealed refrigeration
circuit or repairing refrigerant leaks. (Include Compressor, condenser, evaporator, capillary
tube, refrigerant leaks, etc.)
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 gauge from process tube to
EPA approved gauges from process tube to EPA approved recovery system. Recover
CFCs in system to at least 5%.
2. Cut the process tube below pinch off on the suction side of the compressor.
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.)
5. Replace inoperative component, and always install a new filter drier. Drift dry nitrogen
through the system when making these connections.
6. Pressurize system to 30 PSIG with proper refrigerant and boost refrigerant pressure to
150 PSIG with dry nitrogen.
7. Leak test complete system with electric halogen leak detector, correcting any leaks
found.
8. Reduce the system to zero gauge pressure.
9. Connect vacuum pump to high side and low side of system with deep vacuum hoses, or
copper tubing. (Do not use regular hoses.)
10. Evacuate system to maximum absolute holding pressure of 200 microns or less. NOTE:
This process can be speeded up by 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
system a minimum of 10 minutes. Recover refrigerant, and proceed with evacuation of a
pressure of 200 microns or a minimum of 10%.
11. Break vacuum by charging system from the high side with the correct amount of

Basic test procedure
15
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.
12. Restart unit several times after allowing pressures to stabilize. Pinch off process tubes,
cut and solder the ends. Remove pinch off tool, and leak check the process tube ends.
8.2.4 Special procedure in the case of compressor motor burnout.
1. Recover all refrigerant and oil from the system.
2. Remove compressor, capillary tube and filter drier from the system.
3. Flush evaporator condenser and all connecting tubing with dry nitrogen or equivalent, to
remove all contamination from system. Inspect suction and discharge line for carbon
deposits. Remove and clean if necessary.
4. Reassemble the system, including new drier strainer and capillary tube.
5. Proceed with processing as outlined under hermetic component replacement.
8.2.5 Rotary compressor special troubleshooting and service
Basically, troubleshooting and servicing rotary compressors is the same as on the
reciprocating compressor with only a few exceptions.
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 correct connections.
8.2.6 Refrigerant charge
1. The refrigerant charge is extremely critical. It must be measured charge carefully - as
exact as possible to the nameplate charge.
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 compressor and enter the balance of the
charge, gas only, into the low side.
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.
8.3 Fan motor
A single phase permanent split capacitor motor is used to drive the evaporator blower and
condenser fan. A self-resetting overload is located inside the motor to protect against high
temperature and high amperage conditions.
8.3.1 Fan motor test
1. Determine that capacitor is serviceable.
2. Disconnect fan motor wires from fan speed switch or system switch.

Basic test procedure
16
3. Apply "live" test cord probes on black wire and common terminal of capacitor. Motor
should run at high speed.
4. Apply "live" test cord probes on red wire and common terminal of capacitor. Motor
should run at low speed.
5. Apply "live" test cord probes on each of the remaining wires from the speed switch or
system switch to test intermediate speeds.
8.4 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 motor. A single capacitor can be
used for each motor or a dual rated capacitor can be used for both.
The capacitor's primary function is to reduce the line current while greatly improving the
torque characteristics of a motor. The capacitor also reduces the line current to the motor
by improving the power factor of the load. Run capacitor hook-up line side of the capacitor
is marked with a red dot and is wired to the line side of the circuit
8.4.1 Capacitor test
1. Remove capacitor from unit.
2. Check for visual damage such as bulges, cracks, or leaks.
3. For dual rated, apply an ohmmeter lead to common (C) terminal and the other probe to
the compressor (HERM) terminal. A satisfactory capacitor will cause a deflection on the
pointer, and then gradually move back to infinity.
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.
5. Repeat steps 3 and 4 to check fan motor capacitor.
NOTE: A shorted capacitor will indicate a low resistance and the pointer will move to the
"0" end 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.
