A malfunctioning Speed Queen refrigerator or freezer could be a major inconvenience in addition to the possibility of food spoilage and waste. It is essential to resolve the issue as soon as you notice that your Speed Queen freezer or refrigerator stops making sure food is kept at the proper temperature. The majority of the issues that cause refrigerators and freezers to get too hot can be fixed with some simple troubleshooting steps. In this post, we’ll examine the most common causes of warmer Speed Queen refrigerators and freezers and provide step-by-step instructions for resolving them. We can help you get your freezer and refrigerator in the correct temperature regardless of whether you’re an expert DIYer or novice.
Cold Control Or Temperature Control
The cold control is a temperature-controlled switch that supplies power to the compressor and fan circuits in the refrigerator. The cold control could be out of calibration or malfunctioning if the fan and compressor are not operating properly. The typical fresh food temperature should be 38 degrees Fahrenheit with the control set at the mid-point. Verify that the capillary tube or sensing bulb has not been damaged or out of position and also that wire terminals aren’t damaged or loose.
Unplug the Speed Queen refrigerator before beginning, then open your Speed Queen refrigerator door and locate the control. It’s located inside the control section for fresh foods on the panel, typically behind the temperature adjustment knob.
Remove the control from the appliance and turn it to the most warm setting. After that, set your multimeter to Rx1 to reach the terminals.
The probes are being tested to determine continuity. It should be the reading infinity. Adjust the control to higher (colder) and higher settings, while the probes are still in contact with the terminals. If your reading shifts to zero, it indicates that you are experiencing continuity.
You’ll need a replacement of your Speed Queen thermostat in the event that the control fails to pass one of these tests.
Motor for Evaporator Fan
The Speed Queen fan motor in the evaporator is used to circulate the cold air throughout the Speed Queen refrigerator when the compressor is running. The fan could fail and temperatures within both the fresh food and freezer sections may rise slowly. If this occurs, the compressor will be more frequent and take longer than normal. While the compressor is operating, it is also possible to hear the evaporator fan running at the same time, and the condenser fan that is close to the compressor.
How do you inspect a Speed Queen refrigerator evaporator fan motor:
Disconnect your Speed Queen refrigerator from the power source . Then take off the cover for the evaporator that is located in the freezer compartment.
Motor shaft must flow freely and without resistance. To determine if it is resisting make the shaft turn manually.
If there is a significant amount of ice on the motor, take it out of your freezer to see whether that solves the issue. Also, inspect the motor for signs of wear and damage.
If you cannot turn it easily or it’s evidently worn, you require a replacement Speed Queen evaporator fan motor.
Electronic Control Board
An electronic control board may be found on certain Speed Queen refrigerators. The control board is linked to temperature sensors or thermometers. They keep track of temperatures in freezers and fresh food compartments. This information is then used by the control board to control compressors, fan motors and the defrost system. The electronic control may be at fault for the problem if the temperature is too high. Speed Queen’s electronic controls are expensive, complex, and often reliable. Before you condemn the control, ensure that the compressors, fans and sensors function effectively. Manufacturers might have specific data that can help you diagnose a malfunctioning control.
How do you check the electronic control board on your Speed Queen refrigerator
Make sure to unplug your refrigerator before you begin as you will be handling electrical components.
Locate the electronic control panel and take it out of your appliance. It’s in the Speed Queen refrigerator. The control box is attached to the top of the refrigerator.
Check your control board for signs of damage, such as burnt, wear connections or an arcing.
You will need to replace the Speed Queen electronic control boards when you notice any of these symptoms.
Thermistor or Temperature Sensor
In devices that employ the Electronic Control, a thermistor or temperature sensor can be used to check the freshness of food items and temperatures in freezers. This sensor is small and has the shape of a capsule. It is covered by an opaque plastic shield. The temperature affects the resistance. The control board uses this information to turn on the compressor and fan circuits as well as control the damper control in certain models. A sensor that is damaged or damaged could cause the control board not to turn off the compressor or fans. This can lead to temperatures that are higher than normal for frozen temperatures or fresh food. The individual manufacturers might have specific information for testing these sensors depending on the model that is involved, and may also provide an error message on the electronic control board for certain models.
How do you test the temperature sensor of a refrigerator with an multimeter
Begin by disconnecting the Speed Queen refrigerator. Next, you need to remove the back panel to reveal the control board that is on top.
The control board is equipped with the thermistor(s). Then, remove the thermistor(s) from the appliance in order to test them.
Before testing them, you’ll need to place the thermistor(s) in frozen water for 5 minutes to increase the temperature until 32 degrees F. The thermistor(s) will give different readings depending on the temperature, and the ranges listed below are only applicable to thermistors with temperatures of 32 degrees F.
When you place the probes on terminals and your multi-meter set to Rx1 and Rx1, you should see the reading of 16,600 ohms (+/- 5 percent).
You’ll need a replacement temperature sensor or thermosistor from Speed Queen when you see a reading that is outside of the range of this sensor.
Defrost Timer
The defrost timing device is an electromechanical timer that works with a set of contacts that regulate the compressor circuit and the defrost heater circuit. A timer can trigger an defrost process every 8-10 hours. This occurs about once a day. The defrost timer will usually stop the cycle after 20-30 minutes. Then the compressor and fan will restart.
How to test a defrost timer in a refrigerator using a multi-meter
Find your defrost timer by disconnecting your appliance from its power source. It could be hidden behind the refrigerator’s lower kickplate, inside the Speed Queen refrigerator’s control panel or behind the refrigerator on its back wall.
Once you have located it, take the timer for defrost from the appliance to test it.
Use a multimeter using the Rx1 setting. One probe should be placed on the common terminal. (It must be marked by either “3” or”C”). The second lead should be positioned to touch the remaining three terminals, one at a. The first pair will produce the reading of either zero or close to zero. This indicates that there is continuity. The reading of zero or close to zero may also be given by the second pair. The third pair must also be tested and the reading should read infinity.
If you don’t receive these readings, you will require an replacement timer for the Speed Queen defrost.
Thermostat Defrosting
The Speed Queen safety thermostat, which is connected to the heater that defrosts, is utilized to stop the defrost process when a temperature is reached. It’s typically set between 38 and 47 degrees Fahrenheit. If the thermostat is damaged or remains open circuit, the defrost heater won’t be turned on.
How to test a refrigerator’s defrost thermostat using a multi-meter
Unplug your Speed Queen refrigerator. Find the thermostat for defrost. It could be located under the floor or on the rear of freezer-on-top units. The thermostat that controls defrost can be found on the side of a side-by-side refrigerator.
Once you’ve found it, you must remove the defrost thermostat in order to test it. You will have to remove any obstructions in the way, like the freezer’s contents, freezer shelves or icemaker pieces, and the inside rear, back or bottom panels.
Set your multimeter to the Rx1 setting. Each probe should be positioned on the thermostat wire. If your thermostat is not cold, the multimeter will show zero. If the temperature is warmer (anywhere between forty and ninety degrees Fahrenheit), then this test should yield a result of zero.
If the results you receive in your test differ from the ones presented here You will require a replacement Speed Queen defrost thermostat.
Defrost Heater
The defrost heater is the device that melts ice and frost from the coils of evaporator. It is usually a wire filament wrapped in an aluminum or glass tube. There may be more than one heater depending on the shape of the evaporator.
How do you test the heating element with the multimeter
Make sure you’ve disconnected your appliance from its power source prior to starting.
Locate your defrost heater. It is located behind the freezer compartment of your Speed Queen refrigerator or underneath the floor. Defrost heaters typically are situated beneath a refrigerator’s evaporator coils. It is necessary to clear them of obstructions including the contents, freezer shelves, icemaker parts, as well as the back, bottom, or bottom panels.
Before you can test your heater’s defrost, you need to take it out of your refrigerator. Two wires join a defrost heater. They are joined using slip-on connectors. Hold these connectors with firm grip and remove them from the terminals. To aid you get them off, make use of a pair of needle-nosed scissors. Be careful not to pull on the wires themselves.
Your multi-meter can be used to verify the integrity of the heater. Place the tester’s leads at one terminal. The reading should fall anywhere between zero and infinite.
You’ll require a new Speed Queen heater in the event that you see a reading below zero.
Motor for condenser fan motor
Modern frost-free Speed Queen refrigerators feature condenser coils which are fan-cooled. It’s typically located on the bottom of the refrigerator, near the compressor. The condenser fan moves air through the condenser coil in order to take heat away. The condenser fan motor may be defective if the refrigerator made by Speed Queen is heating up faster than normal and the compressor is running almost continuously. The condenser fan motor operates simultaneously with the evaporator motor as well as the compressor. The compressor will function almost constantly if the fan motor stops spinning.
How to inspect the motor of a refrigerator condenser fan:
Begin by disconnecting the power source of the Speed Queen refrigerator. Then, take off the panel that opens to the rear and find the condenser fanmotor. It’s usually in the lower part of the appliance.
Once you’ve located it check the fan for obstructions or other debris that could hinder it from operating freely. Also, you should inspect the motor of the condenser fan for any signs of damage or wear..
It is necessary to purchase the replacement Speed Queen condenser motor in the event that the motor has developed a seized or worn.
In conclusion it is clear that a Speed Queen refrigerator or freezer that are too hot can be a frustrating and expensive issue. With a bit of troubleshooting and a few basic repair abilities, many of the reasons for hot refrigerators and freezers can be dealt with quickly and efficiently. From looking at the temperature settings and cleaning the coils there are a variety of ways to restore the proper cooling function for your appliance.
