What Is Defrost Timer?
It is a simple motor-commuter device that controls the defrost cycles past opening and closing internal contacts. Why is this important?
The internal contacts maintain the electric electric current flow to the defrost heating element and compressor. In older refrigerators, this type of mechanical kitchen timer allows the current to flow continuously.
Still, in the newer models, manufacturers build the timer in a way that it volition merely function when the defrost bike is running. Primarily, there are two types of defrosting timers- continuous and accumulative timers.
The erstwhile one runs if you keep the refrigerator'due south plug-in continuously. On the other hand, the latter i works when the compressor functions.
How to Test Defrost Timer?
Now that we know near a defrost timer'southward nuts, allow us swoop correct into how you tin can test it. I will be methodically telling y'all the key steps that volition allow you to examination the fridge defrost timer in no time.
Agreement What and Where
The defrosting and cooling of your refrigerator maintains a rhythm, simply like a clock. And then when might yous need to test the timer?
This frosting and defrosting mechanism depend on a pre-set time interval. You will have to test the timer if it fails to switch over between these 2 mechanisms.
The timer will be behind the temperature command if yous own a meridian refrigerator. I or a few screws may secure this device in place. In some models, it is behind the forepart grill "toe-kick" portion of the freezer.
Remove the Timer
In the case of a power outlet timer, you lot have to recollect to unplug the refrigerator before moving onto this phase. Since you lot will be dealing with electrical components similar a timer, it is better to turn off the power to avoid accidents.
Once y'all turn off the ability, go ahead and locate the timer. It may contain one or more than screws that you volition have to unthread in club to pull out the device forwards. I urge you not to pull it out completely, but enough so that you accept no problem removing the wire connectors at the dorsum portion.
Advance Screw
At that place is also an avant-garde screw that you can remove to check whether the defrost bicycle is failing to advance. Turn the screw clockwise, and after some time, you will hear a "click" noise. This noise is an indication that the bicycle of your freezer moved on to the adjacent one.
Meaning, if it was in the cooling cycle previously, it volition now motility on to the defrosting process. At present, you have to wait approximately 35 minutes to check whether this wheel has left the defrosting mode and moved onto the cooling manner.
You can besides listen to the compressor noise to determine that this change happened. What steps you lot will move on next depends on this timer cycle process.
If you notice that the cycle is not moving as it should, you lot may have to alter the timer motor. Notwithstanding, if it does function appropriately, yous volition have to move on to testing the switch electrically. You can too employ this method to exercise a frigidaire defrost timer exam.
Complex Testing
As well the advanced screw, there are also several screws that concord the timer in place, equally previously mentioned. In order for wiring connector disconnection, you lot will have to remove these screws and gently pull out the timer device. You can also firmly pull and stone the connector from left and right to remove it properly.
Luckily, manufacturers key the connector in such a way that you can only replace it from one angle. Therefore, no need to worry about the wire'southward positions and annotation them.
Next, you will demand a multi-tester to test the continuity of the timer. It contains ohms setting X1; gear up up this X1 setting before moving on to the next stride. At present, you will notice that there are specifically four dissimilar terminals and a common terminal. This common last contains either a "3" or "C" label.
For some reason, if your device does not include a label, then practise not be worried; you can however determine the common last by taking annotation of the last that coincides with the connector plug's white wire.
What Adjacent?
Touch one of the probes to the mutual final and another probe to the rest of the terminals. You will notice the multi-tester showing a zero or near zero ohms reading for 1/two last pairs. This reading indicates continuity. Furthermore, delight take notation that the third last pair volition not show any continuity reading.
Now, go alee and locate the timer switch. Move this switch clockwise, unlike you hear a "click" racket just every bit before. This racket will indicate that you lot have reset the timer dorsum to the previous cycle mentioned in the "advance screw" role.
Reward of Defrost Timer
If you manage to maintain all the timer testing steps that I take mentioned, y'all will discover the problem right away. Now, what is all the fuss about this timer? It is important because information technology helps regulate the defrosting cycle of your freezer correctly.
Your refrigerator contains time intervals where the cooling and defrosting process takes function after specific time intervals. A defrost timer test is essential to keep the cycles in check. The device that maintains and regulates the continuity of this mechanism is the defrost timer.
Interestingly, you can use it to set upward the defrosting time so that the freezer functions unremarkably.
Verdict
Dealing with a complicated timer device of your freezer is not an like shooting fish in a barrel task. But why go for professional help when you lot can check out the timer's functions effortlessly? If you follow my guide on how to test a defrost timer, I guarantee that you will identify the problem in no time.
Call up, testing the timer device is ever cheaper than replacing it. Nonetheless, if the timer indicates faulty readings, then it will be better to replace the timer motor instead of but leaving it that mode.
