Your Frigidaire AC compressor might remain inactive due to various factors, including power disruptions, a faulty thermostat, issues with the temperature control board, capacitor or contactor defects, or the accumulation of dirt on filters and coils. Additional potential causes encompass a malfunctioning thermistor, relay board, selector switch, start relay, control board, or non-operational compressor.
Numerous factors could hinder the activation of the Frigidaire AC compressor, and I will assist you in identifying and resolving them.
But how can you determine if your AC compressor is faulty? What are the signs that indicate the compressor is not functioning?
We will address these questions shortly. Before we do so, allow me to elucidate the role of an AC compressor and its significance.
What Does a Frigidaire Air Conditioner Compressor Do?
The compressor functions as the central component, analogous to the heart of an air conditioner, and many of the AC's functions are contingent upon it, particularly the cooling process.
As the name implies, the compressor's primary role is compression. In this context, it takes the refrigerant within the unit and compresses it, then propels it through the entire air conditioning system.
To elaborate on the concept of compression, it involves the transformation of the refrigerant from a low-pressure and cool gaseous state into a higher-pressure form, effectively initiating the air conditioning process. The compressor's operation is pivotal in enabling the AC system to effectively cool your living space.
Signs A Frigidaire Air Conditioner Compressor Is Not Turning On (Indicators of A Bad AC Compressor)
Identifying a malfunctioning air conditioner compressor, particularly one that refuses to activate, can be discerned through the following indicators:
- Unusual Silence: Normally, the compressor emits some noise (though not excessively loud) when it starts and operates.
- Repeated Circuit Breaker Tripping: If your circuit breaker keeps tripping frequently in relation to the AC operation.
- Warm Air Only: When the air vents exclusively dispense warm air and fail to produce cold air.
- External Moisture Leakage: The presence of moisture leakage outside the AC unit, may indicate refrigerant leakage.
If you observe any of these signs, it is probable that your Frigidaire AC compressor is experiencing issues. Nevertheless, it's important to note that the compressor's failure to activate doesn't always imply that the compressor itself is faulty.
As we will explore in the following discussion, other problems unrelated to the compressor may also impede its operation, so it's advisable to investigate these issues before reaching the conclusion that the compressor needs replacement.
Why Is My Frigidaire Air Conditioner Compressor Not Turning On?
One of the 12 potential reasons, as detailed below, could be responsible for your Frigidaire air conditioner compressor not turning on, along with recommended actions to address the issue.
1. Possible Power failure (Lack of Power)
To ensure that the air conditioner receives adequate power and the compressor can function, it's crucial to address potential issues that might disrupt the power supply:
- Check the On/Off Switch: Verify that the AC's on/off switch is in the "on" position. If it's switched off, simply turn it on.
- Inspect the Overload Fuse: The overload fuse can blow out as a protective measure against overheating. To determine its condition, use a multimeter to test for continuity. If it lacks continuity, replace it.
- Examine the Circuit Breaker: If a power surge occurs, the circuit breaker may trip to safeguard the AC. Check the breaker and reset it if it has tripped.
- Evaluate the Power Cable: Ensure that the power cable is not unplugged, loose, or damaged. If the cable exhibits no continuity and is deemed faulty, replace it to restore proper functionality to the AC or compressor.
2. Thermostat Could Be Defective
The thermostat, also known as the temperature controller, contains electrical contacts that can deteriorate and burn out over time. When this occurs, the thermostat loses its ability to activate the AC compressor motor. Therefore, it is essential to perform the following steps to address this issue:
Solution:
- Test the Thermostat: Utilize a multimeter to examine the electrical contacts within the thermostat. If the multimeter shows a lack of continuity, which is a clear sign of a faulty thermostat, it is necessary to replace it with a functioning one.
3. The Temperature Control Board Could Be Bad
The compressor and fan motor depend on the temperature control board to receive the necessary voltage for operation. If this board is malfunctioning, it can result in the compressor not starting when you try to turn on your Frigidaire AC.
Solution:
- Diagnosing issues with the temperature control board can be a complex task. To ensure an accurate diagnosis and to avoid misdiagnosis, it's often advisable to seek the expertise of an HVAC professional. Once it has been confirmed that the temperature control board is indeed faulty, it should be replaced to restore the proper functioning of your AC system.
