Choosing the Proper Compressor
When selecting a compressor on your fridge, there are a number of necessary components to think about:
1. Kind of Compressor
There are two fundamental varieties of compressors utilized in fridges: reciprocating and rotary. Reciprocating compressors use a piston to compress the refrigerant, whereas rotary compressors use a spinning impeller. Rotary compressors are typically extra energy-efficient and quieter than reciprocating compressors.
Here’s a desk evaluating the 2 varieties of compressors:
| Function | Reciprocating Compressor | Rotary Compressor |

b. Reconnect the Electrical Wires:
Reconnect {the electrical} wires to the terminals on the brand new compressor, matching the wire colours and positions.
c. Connect the Piping and Traces:
Join the refrigerant traces and piping to the corresponding ports on the brand new compressor. Use a wrench to tighten the connections securely.
6. Run a Leak Take a look at
Earlier than plugging within the fridge, run a leak check on the refrigerant system. Use a leak detector or apply a soapy resolution to the connections to determine any leaks. If a leak is detected, tighten the connections or seek the advice of a professional technician.
Eradicating the Previous Compressor
Step 1: Collect Instruments and Components
Earlier than starting, guarantee you’ve got the mandatory instruments, equivalent to a multimeter, wrenches, screwdrivers, and wire cutters. Additionally, you will want a alternative compressor suitable together with your particular fridge mannequin.
Step 2: Security Precautions
Unplug the fridge from the ability outlet and discharge any residual electrical energy by shorting the terminals of the capacitor. Put on protecting gloves and eyewear to stop harm.
Step 3: Isolate the Refrigerant Traces
Find the copper refrigerant traces related to the compressor. Pinch or clamp every line securely to stop refrigerant leakage.
Step 4: Disconnect Wires and Fittings
Disconnect all electrical wires related to the compressor and the refrigerant tubing. Label every wire to facilitate reconnecting them throughout set up. Take away any bolts or screws holding the compressor in place, gently prying it free if obligatory.
Step 5: Take away the Compressor
As soon as all connections are launched, fastidiously take away the previous compressor from the fridge and get rid of it correctly.
Troubleshooting Frequent Points
In case you encounter any issues together with your fridge’s compressor, comply with these steps to troubleshoot the difficulty:
1. Test the Energy Provide
Make sure that the fridge is plugged right into a working outlet and that the ability twine just isn’t broken. Reset the circuit breaker or fuse if obligatory.

The overload protector prevents the compressor from overheating. If the protector journeys, the compressor won’t run. Reset the protector and watch for a couple of minutes.
4. Clear the Condenser Coils
Soiled condenser coils can limit airflow and trigger the compressor to overheat. Clear the coils frequently with a vacuum cleaner or brush.
5. Test the Thermostat
The thermostat regulates the temperature contained in the fridge. If the thermostat is defective, it might not ship the right sign to the compressor.
6. Examine the Wiring
Test all of the wiring connections between the compressor and different parts. Unfastened or broken wiring can forestall the compressor from operating.
7. Take a look at the Compressor
Disconnect the ability to the fridge. Take away the wires from the compressor terminals and join a multimeter to them. Set the multimeter to the ohmmeter setting and test for continuity. If there isn’t any continuity, the compressor is defective.
8. Examine the Refrigerant Traces
Clogged or kinked refrigerant traces can limit the movement of refrigerant and trigger the compressor to overheat. Test the traces for harm and guarantee they aren’t obstructed.
9. Decide if the Compressor Motor is Burned Out
| Causes | Signs | Options |
|---|---|---|
| Overheating | Loud noises, extreme vibration | Test condenser coils, clear them if obligatory |
| Electrical surge | Burning odor, smoke | Contact a professional technician |
| Inside put on and tear | Gradual lack of cooling, elevated noise | Change the compressor |
| Beginning capacitor failure | Buzzing noise, not beginning | Change the beginning capacitor |
| Run capacitor failure | Compressor begins however doesn’t run repeatedly | Change the run capacitor |
| Refrigerant leak | Poor cooling, hissing sounds | Contact a professional technician to restore the leak and recharge the refrigerant |
