However, ductwork clogging is not the only issue that causes this error code to occur. In fact there are many other reasons that can contribute to the cause. I will be discussing them in the next section of the article.

LG Dryer d90 No Blockage – Causes and Fixes

Apart from the previously mentioned issues, now is the time to discuss some other issues as well which are the following.


  1. Tripped Breaker

A breaker can trip off due to a power surge and this happens to protect the dryer from possible damages such as fire. As far as LG dryers are concerned, they use Flow Sense technology which can cause error codes like d80 and d90 to occur.

Fix Method

Inspect the circuit breaker carefully and if it is tripped up then make a quick replacement.


  1. Blown-up Thermal Fuse

If you witness a dryer’s thermal fuse to be blown up then it means it was trying to protect the dryer, just like the circuit breaker. As soon as this happens, the error code d90 pops up.

Fix Method

Take a multimeter and test the thermal fuse. If it is showing continuity then it means it is working fine. Otherwise, you will have to buy a new one and replace it with the old one.


  1. Small Clothes Load

If there is a small clothes load then the LG dryer sensors will find it difficult to detect their presence. The dryer sees the clothes as a possible cause for fire triggers. Due to this the error code d95 is made visible to the users.

Fix Method

Don’t put a small load of clothes into the dryer. Make the dryer at least ¾ full and then check whether you are seeing any error or not.


  1. Filthy Lint Filters

The Flow Sense sensors immediately detect the lint buildup due to the presence of lint on the lint filters. Dryer’s sensors categorize the lint as a fire hazard which makes the error code d90 to occur.

Fix Method

Before using the dryer, make sure to have the lint filters clean. If they are clogged with lint then take them out, clean them and then use the dryer as per your preference.


  1. Burnt Out Heating Element

It is a common thing to perceive that whenever any electrical appliance fails up then it is either due to power overload or power surge. The heating element in the dryer might get burnt due to power overload. In case the current exceeds the limit, the sensors will immediately sense that and send the error code d90.

Fix Method

Check the heating element using a multimeter. If there is no continuity shown then you have to replace the element with a new one.


  1. Active Energy Saver Mode

The sensors will sense the enabled energy saver mode when running a cotton or normal cycle and will display an error code d90 to give a warning.

Fix Method

Make sure the energy saver mode is disabled in case it is enabled.

Steps to solve Error d90 on LG Dryer

If you are totally unaware regarding how to deal with the error code d90 then you can follow the following steps to troubleshoot the problem and adopt a possible fix for it.

Step 1

Step 1 involves checking the dryer vent for possible blockages. Look into the dryer vent and closely examine it for lint clogging. If you find it to be one then unclog it immediately.

Step 2

Step 2 involves checking the dryer vent for possible damages and kinking. If you find any kinks then remove them by straightening the dryer vent. In case of other damages, you should consider replacing it.

Step 3

Step 3 involves checking the installation of a dryer vent. Firstly, check whether it is free from certain bends and secondly, the bends shouldn’t be long enough to delay the drying time.

Step 4

Step 4 involves checking the lint filter for possible clogging. You will need to clean the lint filter if it is clogged.

Step 5

Step 5 involves looking for a power cutout. In this case, you need to check the breaker and fuse. If the circuit is tripped then you have to reset it and if there is a blown-up fuse then you have to replace it.

Step 6

Step 6 involves deactivating the energy saver mode if it is ON.

Step 7

Step 7 involves checking the clothes load size. The drum shouldn’t be overloaded or under loaded as the clothes won’t spin properly.

Step 8

The last step involves checking the heating element for possible faults. Take a multimeter to check its working. In case it doesn’t show any continuity, all you have left to do is replace it.
