Question about LG LRE30755 Electric Kitchen Range

Burner on range will not turn off

I have a ceramic glass cook-top electric range (Sharp KB-3300J) with built-in microwave drawer. I'm having an issue with the right front burner not turning off when the knob is in the off position (The right front burner also has small and large cook areas controlled by the same knob). The first time this happened I noticed the hot surface indicator remained on longer than normal and it felt like the burner was putting off heat (although no red glow was seen). I unplugged the range, waited about 15 seconds and plugged back in. I then turned on the burner - large cook area. I saw a red light flash (kind of like when a light bulb burns out) in the center of the cook top (not where a burner is), then the right front burner turned on (glowing red). When I turn the knob to off the on/off indicator light went off but the burner remained on and glowing. I can unplug the range and repeat this process. The other burners appear to work normally as does using only the small cook area on the right front burner.

My questions are:
1.) what's causing this problem and how to fix?
2.) if I don't use the right front burner will it be safe to leave the range plugged in and use the remaining burners, oven, and microwave?

    I have a Frigidaire PLEF398AC Electric Kitchen Range that the left back burner will not go off when I turn the dial to the off position. What causes this and can it be fixed. I have only had this range a year!

    We unpluged it and left it unpluged for about 30 minutes. An error code came one when we plugged it back in.

    I have an LG LRE30755ST stove, left front single size burner will not turn off. I must unplug the stove to get it off. It heats back up when plugged in. Sometimes the larger part on another burner comes on when not turned on.

    I have the same problem. My front right burner does not turn off. Instead, it powers on and off all on its own. Solutions would be appreciated!

Look at the back of your range there should be schemetic for your power control board. look for defective burner wire going into relay. There should be 5 relays in rows. Realy is the problem. I had the same problem with my front left burner stuck on high.
After replacing everything works okay.

Can your microwave work without mica cover?

It can be, but it's not recommended. Food can splatter and get into the waveguide and cause problems. Also if you reach in there with your finger right after the microwave stops, you can get a severe shock (until the capacitor discharges, usually in about a minute). Also the edge is sharp.

Is it okay to use glass whistler tea kettle on ceramic stove top range

I've seen mixed results across the internet on this one. From personal experience, for some reason, my glass teapot left some sort of stain on my ceramic stovetop. It also took longer to heat. I then went out and bought a simple metal one and have been pretty satisfied. If cosmetics are a concern, it's not too difficult a step to pour the water into your teapot after the fact, right?

First of all, if the cook-top broke as a result of a manufacturer defect, the repairs should be covered under the manufacturer's warranty. In this case, the repairs would be done at no cost to you. If, however, the glass top was broken as a result of the consumer, the repair will not be covered (even if it is still under warranty). If this is the case, it does not require an engineer to replace a glass cook-top. It can be time consuming, though. If you are somewhat savvy with fixing things, it can be accomplished by the average do-it-yourselfer. The following link explains how to replace most glass cooktops:

The tedious part of replacing the cook-top is carefully removing and handling each burner element. These are usually ceramic and are very fragile. You must be handled with care. If there is no common disconnect, you also will be required to unplug each burner assembly one at a time and label the wires. A digital camera can come in very handy for this as well. The easiest way to do this is to remove the old shattered cook-top, first and lay it side by side with the new one. Remove and install one burner element at a time.

If you wish to pursue this and require additional assistance, please let me know before you rate the solution. I hope this helps you.

Soup boiked over on stove top

I had some luck removing food and other stains with the new Vielda Glass Ceramic Scrung (its a sponge)

"Special scour sponge for cleaning glass ceramic cook tops without scratching. Eliminates burnt-in stains and greasy dirt film. Removes grease and loose dirt particles. Microfibre side will create a streak free finish."

I found mine at Walmart. It was a little pricey but if you just use the sponge for the stovetop then it will last a very long time.

Hope this helps.
