According to the booklet of the LG Dryer, the 90 % chance of blockage occurring if the vents of the dyer have been choked. But it is not the case in all scenarios, what if d90 does not mean no blockage?
The 90% reasons behind the protrude of d90 error include ductwork choke, tripping of a breaker, a blast of the thermal fuse, a small electric charge, grimy lint filter, heating element exhaustion, or if Dyer is on an “Energy Saver” mode.
Jamming, bending, and entanglement of the dyer duct wall are not the all-time cause of choking. Therefore, this post is all about the error d90 with no blockage. In a few minutes, I will explain the error code, the causes behind it, and how to remove it along with other important information.
We will start with a comprehensive view of solutions along with the reasons for the popping of an error code d90 no blocking. Let’s have a look at it.
LG Dyer Causes and Fixes of Error code d90 No Blockage
| Sr No. | Predictable Reasons | Solutions |
| 01. | Breaker Tripping | Replacing of breaker after tripping |
| 02. | Thermal Fuse Blast | Changing the fuse if it causes discontinuity |
| 03. | Small Clothing Load | Improvise the load to ¾ of its capacity |
| 04. | Grimy Lint Filter | Grimy lint filter must be washed |
| 05. | Exhaustion of Heating Component | For a continuous function, the heating element should be tested and replaced |
| 06. | Energy Saver | Deactivation of Energy saver mode |
What is Error Code d90 and Its Meaning?
LG Dyers is immersed with “Flow sense Technology” to ascertain gasp, especially dirt filter gasp, which could potentially lead to a fire upsurge.
Once the blockage reaches 80%, the error code d80 pops up on the dyer and later it starts measuring the blocking ratio. Once it reaches 90%, the error d90 appears on the dryer.
From the title of this post, it can be clearly seen that the duct blockage is not only the reason for the dryer blockage. Let’s have an insight into those issues.
Causes and Fixes- LG Dryer d90 Error Code
As I mentioned earlier in this post about the ‘Flow Sense’ technology that LG has in its dryers to recognize lint choking and triggering the fire.
So, the Flow Sense technology is not based on the logic of airflow, but it is based on measuring the heat of the dryer. The change in the heat level will cause the fire, therefore, the sensor starts to send warning messages.
If it is error code d90, it means that the dryer is 90% blocked. However, there are several other issues that will cause the change of temperature in the dryer and not connect to the clogging. These issues are as follows:
1. Tripping of a Breaker
The breaker is used to protect the dryer from possible fire. Whenever there is a power surge the circuit breaker trips off. The flow sensor in the LG dryer will sense that and start showing the error code d80%, d90%, etc.
Solution
Examining the circuit breaker, if it trips off, replacing the breaker will solve the problem.
2. Thermal Fuse Blast
There is a thermal fuse in the LG dryers, along with the circuit breaker and it is also used to protect the dryer from catching fire. The thermal fuse is blown away once the temperature reaches its maximum value for the dryer protection. The sensor will sense the temperature change and shows the error code.
Solution
A multimeter is used to test the thermal fuse, if it shows discontinuous function, replacement of the thermal fuse might solve the problem.
3. Small Clothing Load
Sometimes little laundry will create a problem in the dryer, as the sensors of it find it crucial to detect the smaller number of clothes in the dryer tub. The sensors of the dryer will not find enough moisture and consider it a potential threat to cause a fire. The sensors will then send d90 error code warnings.
Solution
To avoid this scenario, fill the laundry tub to ¾ of its capacity and do not overload it.
4. Grimy Lint Filter
If the dirt filter (or lint filter) does not show blockage because of the dirt, the flow sense technology sensor will detect the dirt buildup due to already present dirt on the filter. The dryer will consider the dirt as a possible fire risk, and enable the dryer d90 code or any other.
Solution
The dirt filter should be cleaned on a regular basis to avoid this issue. Cleaning of the filter is very important every time the dryer is in use.
5. Exhaustion of Heating Element
Due to power overload, the heating element will be burnt out. Due to the large electric current, the temperature change will occur and the flow sense sensors will send the warning messages of the d90 error code.
Solution
To find the heating element in proper functioning, it is better to check its contact points of it with a multimeter. If this shows discontinuity, it must have been replaced.
6. “Energy Saver” Mode
Whenever during the normal or cotton laundry running, the energy saver mode is activated, the sensor will show the error code d90.
Solution
Deactivation of the “Energy Saver” mode will solve the problem.
Steps to Fix the Error Code d90 on LG Dryer
Whenever it is the situation of error code d90 on the LG dryer, lint filter clogging is the first potential threat ( because 90% blockage is caused by it), then you have to go through the non-blocking issues that will be discussed earlier.
So, let’s see step by step how to fix the error code:
Step 1. Checking of Dyer Vent for Clogging
Remember that the error code will occur due to clogging. Therefore, begin by looking at the signs of clogging and clearing them. First, you must look for a dryer duct and check it properly inside and out for dirt blockage. If the duct is clogged, unclog it by cleaning it.
Step 2. Investigate damages, crushes, and Kinks of the Dryer Vent
After the unclogging of the dryer vent, go to the duct if there is any damage, crushing, or kicking is present. If any damage or crushing happens in the dryer replace it immediately, or if any kinks are there, straightening the dryer will remove the error code d90.
Step 3. Dryer Vent Proper Installation
The next step is the proper installation of the dryer. Examine the dryer duct to free it from bends and it should not be too long to cause a delay in dryer time. Therefore, if the vent does not meet the requirements, you need to replace it.
Step 4. Cleansing of the Lent Filter
The lint filter should be cleaned properly to avoid lint clogging. Remove it gently from the dryer and clean it with proper care.
Step 5. Check for Power
The power cutout occurs due to two different elements of the dryer. First, the circuit breaker tripping causes the power cutout and then there is a thermal fuse burning. Replacing both elements will solve the problem.
Step 6. Deactivation of the “Energy Saving” Mode
The energy-saving mode should be deactivated while functioning the dryer.
Step 7. Proper Load Size
The laundry tub should be half while working. For proper spinning of the clothes, fill it to ¾ of the tub capacity and do not overload it.
Step 8. Investigation of the faulty heating element
Investigation of the heating element through a multimeter will show its proper working of it. If the heating element is faulty, replace it.
Why it is important to know about the Troubleshoot of the error code d90 in LG Dryers?
According to the survey, it has come to notice that 80% of the houses are on fire due to dryers, even if they are easily stopped. If an excessive amount of lint is present in the dryer vent, it will trigger the fire except you act.
But you can act only in the scenario when you have the information about the signs, and what means what.
If the clogging rate is 90%, it shows the error code d90, and at that time it is important that you disconnect the dryer, find the source of the jamming, and solve it. In this way, you can avoid the fire outburst and damage to the dryer.
Another way to avoid this difficulty is to shorten the dryer’s time, which in case of blockage becomes lengthier.
What if error code d90 of the LG Dryer does not Clear?
If you go through all the 8 steps mentioned earlier, and still the error does not clear, resetting the dryer is another option. Let’s talk about the LG dryer error code d90 resetting:
- 5- Minute Dysconnectivity of the dryer
- Firstly, disconnect the LG dryer from the wall switch.
- Secondly, plug it in again after 5 minutes of waiting.
- If there is any dirt present on the lint filter, first washed it properly and then plug it again.
- Signal Reset+ Dryer Time
The method used in this technique is as follows:
- Plug in the dryer.
- Pressing for about 3- minutes the Dryer Time+ Signal Reset.
- Wait for the error code to vanish.
- Other methods are pressing the Time-Dry +Wrinkle Care, Energy Saver + Less Time, or Energy Saver + Wrinkle Care rather than Time-Dry + Signal.
Frequently Asked Questions
A. Your dryer shows this warning message when the clogging reaches 90%. So, you need to cut the power supply of the dryer and remove the blockages. This includes the cleaning of dirt from the vent, dirt from the lint filter, and untwisting the sharp duct.
