If you are looking for a True refrigerator troubleshooting manual, this blog will help you. When you want to troubleshoot True refrigerators, it can be challenging. Several components are working together in the system to provide cooling. Even a renowned brand of refrigerators like True will need repair sometimes. So, you need maintenance. Otherwise, you may get maintenance issues or any other issues so that you have to know how to fix them efficiently and quickly. You can solve the problem yourself with the help of our True refrigeration T 49 troubleshooting tips. Continue to read this post...
True Refrigeration T 49 Troubleshooting
Below is the True freezer t-23f troubleshooting guide for your common problems.
True refrigerator compressor not running
If there is no power at the compressor terminals, check for interruptions in the power supply.
If the power is available but the compressor doesn't run, then check the voltage at the compressor terminals while starting it. See that the wire sizes are adequate, electrical connections are loose or the power supply is inadequate. It's not possible to develop sufficient torque to start the compressor when the voltage is below 90%.
On single-phase compressors, a faulty capacitor or relay will prevent the compressor from starting. If it starts but is unable to do so or getting any humming sound, then verify that the contacts are fused or damaged. Make sure relay points have to be closed during the initial starting cycle. But, it should be open while the compressor comes up to speed.
You need to remove the wires from the starting capacitors and relay. Check for continuity of it with a high voltage ohmmeter. If there is no continuity or giving incorrect results, you should replace the relay. You can get the True t-49f wiring diagram in the manual for reference.
If the compressor has the correct voltage and no current is drawn, remove all wires from terminals and verify the continuity through the motor windings. You can check the continuity of single-phase motor compressors from terminals C to R and C to S. If it is with line break inherent protectors, an open overload protector may cause for lack of continuity. When the compressor is warm, wait for some time to cool and re-check. If you get incorrect results or no continuity through all motor windings, make sure to replace it.
Condenser Coil is Dirty
After a long period of use, the condenser coils may get dust. This dust and dirt will cause you to overheat the cabinet and wear down the other parts in your refrigerator. So, you should clean the coil with a solid vacuum or air compressor. If you clean the unit at least every three months, then you can stop overheating issues.
If the condenser coil has a thick grease buildup, then it needs some special instructions that are given in the manual. For damaged coils, you have to go through its replacement or repair. You can buy a True condenser coil at PartsFPS for replacement. Check for fins damaged or crushed. They should be straightened.
Frozen Evaporator Coils
Evaporator coils cool the inside of the refrigerator by creating an insulating barrier to shield it from heat transfer. However, ice buildup may occur on the coils to the point that they freeze over. Three common signs of frozen coils include a constant ticking sound from inside of the fridge, a rise in cabinet temperature, and a puddle of water underneath the True T 49 refrigerator.
Overloading of the fridge with humid products or blocking airflow at the vents also cause the coils to freeze.
Fridge Door Doesn’t Close
Due to a broken gasket, the refrigerator door won't seal shut. The gasket allows the air to escape the unit and causing fluctuations in the temperature inside the fridge that will affect the safety of food. So, replace your True fridge gasket if it’s not good. Moreover, you must find the gasket with the model number.
Leveling is also one of the reasons that the door isn't close properly. So, check for uneven sides and place them properly.
Common Error Codes
True refrigerator's error codes help you to identify what's going wrong in your unit. Here are some error codes that you might see on the unit.
PI Alarm or EI Code: It indicates a failure in the thermostat failure. PI displays on fridges that have Dixell electronic controls. And, EI displays on units with LAE electronic controls.
P2 Alarm or E2 Code: This error indicates an evaporator probe failure.
P3/ E3: When an auxiliary or display probe failure occurred, it will be displayed.
HA Alarm or thi Code: This code indicates the unit is at a high-temperature setting. So, once verify the True refrigerator temperature control settings.
LA/ tLo: Indicates that the machine is at a low-temperature setting.
However, regular maintenance helps to lower issues for larger repairs in the future. When you need True replacement parts, you can buy them from PartsFPS. We also supply original thermostats for True refrigerator thermostat replacement. Hence, order online at partsfps.com
