A refrigerator is an open system that moves heat from a room or other enclosed space to a warmer room or region.
It cools down due to dissipating the heat from this region, keeping food and other goods at a cool temperature.
Although refrigerators seem to break the second law of thermodynamics, the labor required as an input into the system is the main reason they don’t.
They function similarly to heat pumps but cool an area rather than heating it.
There are many issues you may face in the routine maintenance of the Frigidaire refrigerator.
To quickly diagnose issues with the refrigerator unit, error codes are quite helpful.
These are signals in the form of letters and numbers which detect the set of parts causing failure.
In case of appearance of any error code, don’t be panic.
It is simply an indication to fix the issue in order to run the refrigerator smoothly.
These errors may occur in refrigerator temperature sensor, freezer temperature sensor, evaporator fan circuit, and electronic control board etc.
The most common is Frigidaire refrigerator Error code t1.
In Frigidaire Refrigerator, the error t1 is associated with freezer temperature sensor.
The Frigidaire Refrigerator Error code t1 indicates that freezer temperature sensor is either Open or Short.
Meaning of Frigidaire Refrigerator Error Code t1
Frigidaire refrigerator Error code t1 is most common error code.
It is associated with freezer temperature sensor.
Frigidaire refrigerator Error code t1 means that Freezer Temperature Sensor is shorted/open and needs to be fixed or replaced.
Causes for Frigidaire Refrigerator Error Code t1
It is widespread that modern Refrigerators have electronic sensors and other associated circuitry.
Small Electrical sensors are susceptible and may get damaged due to various environmental and abnormal conditions.
Both Open and Short conditions of temperature sensors are not desired since they create different
hurdles in functioning of device and can cause potential damage.
Therefore, it is essential to be aware of the causes of these abnormalities.
Following are the major causes of Frigidaire Refrigerator Error code t1.
Wiring Issues
One of the major reasons of error t1 is improper wiring connections.
Loose wiring or connections malfunctions the performance of the refrigerator.
For proper transmission of signals, it is necessary to avoid any loose connections.
In case of damaged wiring, short circuit or surges occurs.
This issue is due to the negligence of technicians who do not perform the wire connections job perfectly.
Other than this, this issue arises when relocation happens.
In case of relocation, once refrigerator fixed to new place, the wiring may not connect properly therefore this error appears on the screen.
This kind of problem may be critical and needs to be fixed as soon as possible.
Electronic Control Board
The problem is a damaged sensor and is the leading cause of this of Frigidaire refrigerator Error code t1.
The freezer temperature sensor is connected to the electronic control board as main power comes from this unit.
The control board uses sensor readings to regulate power to compressor and evaporator.
The electronic control board is responsible for various functions including cooling, set the freezer at defined temperature, and defrost times.
The error may arise due to the failure of this equipment.
Here is the potential that it is failed to detect the resistance of the sensor.
As the result of lack of detection, the freezer temperature sensor is short/open.
Faulty Freezer Temperature Sensor
There are strong chances that the freezer temperature sensor is faulty.
The sensor in built functionality may not work properly due to which error t1 occurs.
This may be due to broken contact assembly inside the sensor.
Due to the faulty sensor, the error shows despite of smooth functioning of refrigerator which lead to time waste.
It will tell the freezer to set temperature to its own rather than desired one.
Hence, it erupts the normal functions of refrigerator.
Control Panel Issues
If we look into the main control board and user interface, physical connections exist between the control panel and the sensors.
Other than above mentioned issues, if freezer temperature sensor gives this error on display, it may be due to the malfunctioning of control panel.
In this case, help from technicians is mandatory to avoid long term penalties.
In case of issue arising from control panel, the reset option is not helpful at all.
Technicians must be called to oversee the matter with great care.
Blockages
Proper airflow is necessary for efficient working of refrigerator.
The air circulation is imperative to keep things cooled.
In some cases, it is being observed that freezer temperature sensor creates an issue when there is a lot of volume inside which blocks the passage for air vents.
If inside freezer is too icy, it will create problems for vents.
Thus, error ert1 appears on the screen.
Environmental Damages
Electrical sensors are susceptible and may get damaged or burned due to abnormal weather conditions.
Moisture content in the air may affect the performance of the sensors, and you may face Frigidaire refrigerator Error code t1 due to the freezer temperature sensor.
In hostile settings, sensors may sometimes malfunction or deteriorate.
Your thermocouples may be intermittently failing, or your meters may display “Open Circuit/Short Circuit.”
Fixes for Frigidaire Refrigerator Error Code t1: Check And Repair
Reset your Frigidaire refrigerator
Resetting your Frigidaire refrigerator may involve a lot of steps that should be performed step-wise.
However, it is a simple step but may apply some technical measures.
It will help you remove the t1 code error of your Frigidaire refrigerator while opting for the solution of resetting.
It should be performed just by cutting down the power supply with the help of a breaker and waiting for some time.
Again, energize the supply to turn on the Frigidaire refrigerator.
Hopefully, it will resolve the issue at the early step of this fixation.
Otherwise, you have to perform a hard reset, the details given in the upcoming subhead.
Try a Hard Reset
Hard reset could be helpful to remove the code error t1, which mainly occurred due to the freezer temperature sensor and the associated connections.
Follow the below-mentioned steps in sequence to implement the t1 code error removal.
(i) By shutting off the circuit breakers for one (1) minute, you may turn the device off.
(ii) By turning on the circuit breaker, turn on the device (s).
(iii) For one (1) minute, keep an eye on the Frigidaire refrigerator to ensure the error code t1 doesn’t appear again.
Check wire connections
The very first step is to make ensure that all wires connections are properly linked.
For this, unplug the refrigerator and do proper check the connections between freezer temperature sensor and electronic control board.
Make sure that all connections must be tight.
In case of loose wires, reconnect them. Then switch on the refrigerator.
It should work smoothly now if wiring was an issue.
An important point to be considered is that there is no restart button in Frigidaire Refrigerator.
To restart the refrigerator, power cycling is done i.e unplug the refrigerator from socket for few minutes and then re-plug it to start the refrigerator.
Multimeter Testing
If the wiring is not an issue that causes ER t1, then sensor must be tested if it is working properly or not as discussed earlier as case of a faulty sensor.
Firstly, the freezer temperature sensor needs to be unplugged from wire harness.
After this, its resistance is measured using multimeter.
If it is in certain range, then things are okay, and sensor is not faulty.
But if it shows infinite resistance, then sensor is faulty i.e it cannot be repaired and needs to be replaced.
The sensor wiring failure needs to be addressed and repaired by professionals.
Checking the freezer temperature sensor needs a correct way, and you may follow the steps below.
- Verify the correctness of the -ve and +ve leads and the cable type.
- Inspect your readings for any effects from nearby heat sources.
- Check the settings on your temperature controller and display.
- Resolve open/broken circuit/sensor errors
- Check the sensor physically for damage.
- Verify the temperature transmitter.
- Utilize a multimeter to test a malfunctioning thermocouple.
- Use a multimeter to check a defective resistance thermometer.
Electronic Control Board
If the sensor wires are working properly and sensor is not faulty, then next step is to check the functionality of electronic control board.
The resistance of sensor needs to be measured with wires that are connected to the electronic control board.
Connect the freezer temperature sensor to it via wires and unplug the connector from board to measure solely the resistance from wires.
This resistance must read the same as the resistance of the temperature sensor.
If the meter fails to detect sensor resistance, it means electronic control board is malfunctioned and needs to be replaced.
Replacement of the primary circuit may be helpful in the removal of this t1 code error in this case.
This step may be critical, and you should be required by a trained professional to replace the main circuit board.
Control Panel
The other way to restart the device is to move towards the control panel.
There are chances that buttons may stuck on panel due to which temperature sensor in freezer shows error t1.
Here, turn all the controls to zero. Ensure that freezer is off.
Then after few minutes, switch on the device.
By rebooting, this issue will resolve in case the control panel is working normally.
Other check includes the wiring that may need to be replaced.
Make sure the wiring including harnesses is properly connected.
However, in this case technical help can be taken if issue arises.
Air Vents
The last step includes the checking of air vents.
One must make sure that air vents are doing their job effectively i.e circulate cold air.
The freezer temperature sensor may get open/short due to choked vents.
Don’t too overloaded the freezer with mass items since overloading causes issues for evaporator, compressor, and other equipment.
Too many items disrupt the airflow and build the moisture.
Hence, make sure that all air vents are open, and things are placed in a manner.
All these are applied in both Open and Short cases.
Final Thoughts
Now you know how to fix the Frigidaire error t1.
Code error t1 in the Frigidaire refrigerator is due to a faulty temperature sensor, loose connections, moisture contents in the connectors, and a faulty main control board.
First you need to find the main cause behind this error, so that you can figure out right solution for this error code.
