First of all, here is the main ONLINE SUPPORT page for your model:
http://www.lg.com/us/appliances/ranges/LG-electric-range-LRE30453ST.jsp
To view the Support Page just use your mouse to click on the link, which is the underlined and highlighted text just above. This will open a new web browser page automatically for you and allow you to view the information at the website indicated.
To download and view the Owner's Manual with operating instructions, just click on the SUPPORT button on the right hand side of the main support page when you get there.
Then click on the ENGLISH button under DOCUMENTS - RANGES MANUAL.
When it asks you if you want to open or save the document, select SAVE and then choose a place on your computer to save it like the DESKTOP so you can find it easily later.
When the download completes, click OPEN, and then you can view the contents of the manual.
You may need ADOBE READER installed on your computer to read PDF documents. You can download this free at
WWW.ADOBE.COM if necessary. Click on the DOWNLOAD ADOBE READER button on right side of the ADOBE home page when you get there and then follow the onscreen instructions to istall it.
See page 25 of the OWNER'S MANUAL for detailed instructions and illustrations on how to carry out the SELF CLEAN procedure.
Please comment back here to this page if you have any questions, have difficulty accessing the links, or just require further general assistance and I will respond as soon as I see it.
Thank you very much and good luck.
