Besides the frustration of the sight of wilting veggies, you will be concerned about the safety of your food and the fridge’s functionality. This scenario can force you to throw away all your stored food items and hurry to call in repair technicians.

But don’t freak out! This fiasco is more common than cars running out of fuel. Additionally, there are some simple steps you can take to troubleshoot and solve this issue yourself.

In this guide, we’ll understand the common and unique causes behind a lukewarm true refrigerator. Also, we’ll find suitable fixes to restore your True refrigerator to its optimal performance.

Why Is Your True Refrigerator Not Cooling?

Your true refrigerator relies on a delicate harmony between its internal components to provide the expected cooling efficiency. Unfortunately, many culprits can disrupt this harmony leading to inefficient cooling. Here’s a quick overview of some culprits:

  • A leak or blockage in the refrigerant system.
  • A faulty thermostat that disrupts the desirable temperature settings.
  • Frozen evaporator coils hinder the proper circulation of cool air.
  • Dirty condenser coils that can’t release heat correctly.

Now, let’s get into the details of the common and unobvious culprits and their fixes.

1a- Refrigerant Leak

This issue occurs when the coolant substance escapes from the sealed coils of your True refrigerator. By default, this substance absorbs the heat from the fridge. Then, the refrigerant releases the heat through condenser coils outside the fridge. This is how your true fridge maintains its cold air and food freshness.

Refrigerant leakage happens due to wear and tear, vibration, and corrosion. This problem makes the levels of refrigerant drop significantly and reduces the cooling performance.

1b- How To Fix Refrigerant Leak

Before trying to fix this issue, you should know that refrigerant systems are complex and require specialized treatment and equipment. Also, you shouldn’t attempt any repairs before disconnecting your True refrigerator from its power source.

  1. Remove the back panel: Valves and lines of the refrigerant system are located behind the rear panel. So, gently detach the screws and remove the panel to view these lines.
  2. Identify the leak source: Refrigerant is a sort of hot gas. Therefore it is difficult to visually identify this leakage. You can use a refrigerant leak detector. This device acts as a sensor to detect refrigerant leaks. This detector uses light or sound to alarm you about the problem.
  3. Form a soapy solution: In case this detector isn’t available, you can mix mild soap with water. Fill a spray bottle with this liquid mix and spray it all over the refrigerant system. You can detect a leaky spot when you notice bubbles forming on these spots.
  4. Fix the leakage: In case of minor leaks, you can use epoxy to reseal leaky tubes or valves. Major leaks may call for replacing the valve or line. If you aren’t familiar with replacing refrigerant lines, ask for professional help.
  5. Recharge the system: Again, giving the system a new charge is a pro act, so don’t hesitate to call for help. If you know your way around the system, you can recharge it acutely to substitute for the lost refrigerant. Use a gauge set to know when to stop.

2a- Faulty Thermostat Settings

The thermostat is responsible for controlling the internal temperature of your True refrigerator. This component signals the compressor to turn off and on. This way your fridge can maintain the desired temperature.

The incorrect thermostat setting is the most common reason behind the cooling woes of your fridge. Depending on the faulty settings, your true fridge may overcool or undercool. Additionally, a faulty thermostat will put more strain on the compressor and it may eventually falter due to continuous overwork.

The wrong settings happen due to these factors:

  • The presence of dirt, dust, grease, and food debris blocks the thermostat and prevents it from getting accurate temperature readings.
  • Setting the appliance too high or too low for the type of preserved food or the ambient temperature.

2b- How To Fix Faulty Thermostat Settings

You can easily diagnose improper thermostat settings by checking its dial or screen. To ensure whether you have the right or wrong settings, you can refer to the manual of your True refrigeration equipment.

You can restore the correct settings through the following steps:

  1. Find the thermostat: Start by removing the fridge from the power cord and locating this component at the bottom of the fridge. It is usually covered by the back panel. Remove its mounting screws.
  2. Clean it thoroughly: Use a brush or a vacuum cleaner with a nozzle attachment to remove the obstruction.
  3. Readjust the settings: Adjust the thermostat settings to achieve accurate temperature readings and optimal cooling efficiency. If the issue persists, you may have a defective thermostat.
  4. Replace the thermostat: Use your screwdriver to detach and remove this part of the fridge. Install a new one and make sure the wiring and the sensor are working properly. Keep in mind that replacing a thermostat isn’t for everyone. If you are uncertain about your skills in this field, it’s better to look for a reliable professional.

3a- Bad Perimeter Heater

Ever imagined that this tiny soldier around the door frame or gasket is responsible for your True refrigerator not cooling? This component runs along the edges of the door. It is responsible for the prevention of frost and condensation formation on the door seal.

Therefore, the perimeter heater plays a crucial role in trapping the cold air inside the fridge and keeping the hot air outside.

A troublesome heater is usually associated with faulty welds, frayed wires, or even a malfunctioning thermostat.

A problematic perimeter heater may overheat and melt the door seal or the frame. This can create cracks that allow the cold air to escape and the warm air to enter. This can affect the cooling efficiency of your True refrigerator and compromise your food quality and safety.

3b- How To Fix Bad Perimeter Heater

A bad perimeter affects other components including the door gasket and compressor. To properly troubleshoot this component follow these steps:

  1. Look around the door frame:  You can find it nestled around the frame or gasket. It looks like a thin metal strip. Also, you need to remove the toe grill to expose the thermostat and wiring that are connected to the heater. This grill is at the bottom of the fridge and is tightened by bolts.
  2.  Check for damage: Sometimes, this visual inspection reveals any issues with the perimeter heater. Look for cracks on the seal or loose connections.
  3. Test for resistance: As with any electrical appliances or components in your True equipment, use your multimeter to test this heater. If it shows inconsistent, too-high, or too-low readings, you should get a replacement. The owner’s manual is useful for reading references.
  4. Test with a thermometer: If testing with a multimeter is challenging for you, you can use a separate thermometer. An infrared thermometer can detect the heater’s temperature. If the readings show high temperatures, this indicates overheating. Overheating requires immediate replacement of the heater.
  5. Remove the mounting clip: Look for clips or screws holding the heater in place. Carefully pull out the heater and disconnect the wires. Replace the heater with a new one and reconnect the wires.

Remember: handling the electrical components of your True fridge requires sufficient knowledge and expertise. So, don’t approach these parts if you are a DIY novice or unsure of what to do. Don’t forget to remove the appliance from its outlet to avoid electrical shocks or hazards.

 4a- Problematic Compressor Motor

To fully understand the function of your True fridge’s compressor motor, you should think of it as an air conditioner. In both appliances, this component compresses and pumps refrigerant vapor through the coils and creates the expected cooling effect.

The main culprits behind a faulty compressor are usually wear and tear, power surges, or overheating. The most common issues in the compressor happen due to malfunctions in other parts, such as unclean condenser coils, thermostats, or even the condenser fan motor.

Each one of these issues can make your True refrigerator not cool as usual with or without affecting the compressor directly.

4b- How To Fix Problematic Compressor Motor

DIY troubleshooting of the compressor isn’t advisable if you are not familiar with similar issues. Unknowledgeable repair attempts are risky and may result in warranty complications. However, if you have previous knowledge of handling these problems, follow these steps:

  1. Find the motor compartment: Start by removing the panel at the back of the refrigerator. Search for a small tank made of stainless steel, with two copper or aluminum tubes coming out from it. The smaller tube is called the compressor discharge line, while the larger one is the suction line. If you find this tank, this is your compressor.
  2. Do the old cleaning trick: Sometimes, dirt and debris block the thermostat from performing its function. Use a coil brush or any other soft brush to clean the thermostat and its components.
  3. Find the relay: Look for the compressor start relay on the right side of the compressor. This tiny box helps the compressor to start and stop accordingly.
  4. Disconnect and test the relay: Carefully use a screwdriver for this task and test with a multimeter. Check the manual for correct reading ranges. If it provides the wrong readings, replace the relay. Reconnect the new relay the same way its predecessor was.
  5. Inspect the compressor’s discharge line: Look for the copper tube, we explored earlier. This tube carries the hot refrigerant gas from the compressor to the condenser coils. Remove it and free it from dirt and debris using a brush. If it appears damaged, replace and reconnect the new line. If this doesn’t resolve the issue, then your old compressor is not functional.
  6. Replace the compressor: Remove the screws or bolts that secure the compressor unit to the fridge. Carefully lift the old compressor and insert the new one.
