If your Frigidaire refrigerator is not cooling but the freezer works fine, you are not alone. Many homeowners in Houston, Katy, Sugar Land, and surrounding areas contact us at HomeFix Appliance Repair with the same issue. Below is a real repair story and a complete guide on what can cause cooling problems in a Frigidaire fridge and what you can do about them.
Real Repair Case in Houston: Fresh Food Section Over 50°F
A homeowner in Houston scheduled a service call for their Frigidaire side-by-side refrigerator, model PLHS267ZDB7. While the freezer section kept everything frozen, the fresh food compartment stayed over 50°F—far too warm for safe food storage.
When our technician arrived, initial testing showed the evaporator fan was intermittently working. This fan is essential for airflow between the freezer and refrigerator compartments. Without proper airflow, cold air doesn’t reach the fresh food side.
Step 1: Identifying the Problem
The fan sometimes spun but often stopped without warning. Since intermittent problems can be tricky, our technician decided to order both the evaporator fan motor and an Adaptive Defrost Control (ADC) board. This board controls not only the defrost system but also manages power to several internal components, including the fan.
Step 2: The Surprise Discovery
When the technician returned with the parts and disassembled the control panel, he discovered one of the capacitors on the original ADC board was visibly bulging. A swollen capacitor is a common sign of electrical failure. That explained the irregular behavior of the evaporator fan.
Ironically, at the moment of inspection, the fan was working perfectly. This is a typical sign of a failing board—intermittent performance that masks the problem temporarily.
Both the ADC board and fan motor were replaced as a preventive measure, and the unit resumed normal cooling within 24 hours.
Common Reasons Why a Frigidaire Refrigerator May Not Cool Properly
If your Frigidaire refrigerator is not cooling at all or is struggling to maintain proper temperatures, here are the most common issues we see in the Houston area:
Failed Evaporator Fan Motor
If the fan doesn’t circulate air, the fresh food section won’t cool. Often it’s the motor, but sometimes wiring or control boards are to blame.
Defrost System Failure
In many Frigidaire models, the defrost thermostat or heater fails. Ice builds up on the evaporator coil and blocks airflow. Without that air movement, the fridge warms up.
Leaking Evaporators in Newer Models
Some newer Frigidaire refrigerators have issues with evaporator leaks. These leaks cause refrigerant loss and eventually lead to poor cooling or a complete no-cool condition.
Worn-Out Thermostat (Cold Control)
A mechanical thermostat may stick or fail to send the signal to turn on the compressor. The fridge won’t cool even if everything else is fine.
Start Relay or Overload Failing
If your refrigerator compressor doesn’t start, it could be due to a faulty start relay. That’s a small component that helps the compressor turn on.
Main Control Board Issues
Just like in the real case above, faulty capacitors or corroded traces on a control board can cause sporadic cooling failures.
Airflow Restriction by Ice
In top or bottom freezer models, ice buildup can block the air return vents. No air = no cooling.
Fresh Food Compartment Freezing
Many Frigidaire fridges have a known issue where the top shelf in the fresh food compartment gets too cold. Eggs and water bottles may freeze. In this case, we recommend raising the fridge temperature setting. Replacing the damper, thermistor, or board often does not solve this issue long-term.
How to Diagnose a Frigidaire Refrigerator That’s Not Cooling
Before calling for service, here are some steps you can try:
Check the Fan: Open the freezer and listen for the evaporator fan. If it’s silent, it may be bad.
Inspect for Ice Buildup: Remove the rear freezer panel. If the coil is encased in ice, the defrost system may have failed.
Compressor Check: If the compressor is not running, test the relay or overload protector. You should hear a click and feel a slight vibration.
Look at the Evaporator Frost Pattern: A healthy evaporator coil should be evenly frosted. If only a small portion is icy, this might mean there is a sealed system leak.
Important: Repairs to sealed systems (like replacing a leaking evaporator or compressor) require EPA certification and special tools. DIY repair is not allowed and can be hazardous.
Can You Fix It Yourself?
Yes, in many cases. Here are the steps:
Unplug the refrigerator. Safety first.
Clean the condenser coils, air vents, and check door seals.
Check the evaporator fan: is it running when the door switch is pressed?
Remove the rear freezer panel and inspect the evaporator coil.
Even frost: Good
Partial frost: Likely sealed system issue
Block of ice: Likely defrost system issue
Use a multimeter to test:
Defrost thermostat (should read continuity when cold)
Evaporator fan motor (check for resistance)
Start relay (shake test or continuity)
If you’re unsure or see signs of sealed system failure, call a professional.

Frequently Asked Questions
Most likely, the evaporator fan isn’t working or airflow is blocked due to ice buildup or a bad damper
Yes. If the board isn’t sending power to the compressor or fan, the fridge won’t cool properly.
If your evaporator is covered in ice and the fan is working, the defrost thermostat or heater may have failed.
If the sealed system is intact and parts are available, yes. Frigidaire units are often repairable with common components.
Try raising the fridge temp setting. This is a known issue in many Frigidaire models and often doesn’t require part replacement.
