What should I do if there is a smell when the air conditioner is turned on in summer?

Solution: The odor of the air conditioner is caused by the growth of mold. Open the panel of the air conditioner, take out the filter and clean it, then clean the internal dust, install the air conditioner, and turn on the air conditioner for half an hour to ventilate the room. That’s it. Air conditioning odor is caused by the growth of mold. If the air conditioner is used for a long time without cleaning, dust and debris will enter the air conditioner. The air conditioner will produce some moisture during operation, which will breed mold over time. The smell will spread as the air conditioner works. . First, open the panel of the air conditioner and take out the filter. If there is too much dust on the filter, you can first blow off some floating dust with cold air, and then soak it with air conditioner cleaning agent. If there is a musty smell, there will be bacteria present, so you need to add disinfectant for cleaning. To clean and disinfect the indoor heat sink, use a special air-conditioning cleaning agent to spray evenly on the heat sink, soak it for 10 minutes, and then spray it with clean water. Then turn the air conditioner to working mode, and the internal sewage will be discharged through the drain pipe. Clean some dust inside the air conditioner panel, and then install the air conditioner filter. After installing the panel, turn on the air conditioner for about half an hour to let the inside blow through, and then ventilate the room. This answer applies to most air conditioner models such as Gree/Gree KFR-50GW.
