Question about LG LRE30451ST Electric Kitchen Range

Open Question

Metallic mark in the burner area of my 1 month old LG -LR30453ST

The cook top is black, so this mark is very noticeable. Is this a manufacture defect or something that cooking may have caused? I have used a glass top cook top for 15 years and this has never happened before. Lg is telling me a service tech needs to come out to look at it, but will most likely determine it is a cosmectic blemish....Help please.

SOURCE: burner on range will not turn off

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.

SOURCE: LG LRE30451 won't maintain temperature

Check the oven temperature probe (thermister) to see if it is good. To check it, use a multi-meter and Ohm it out. It should be between 1100 and 1600 Ohms. If it is out of tolerance, you will need to replace it. Here is the part to order.

How to test surface burner on Electric range


In order to test the surface burner on your electric range, the following steps should be taken:

  1. Before repairs or testing can begin you must disconnect the electricity at the fuse panel, at the circuit breaker panel, or by pulling the plug. Make sure the power is off before proceeding. A jolt from 220 volts can be fatal, use caution!


  2. Remove the surface burner from the stove top. On most electric ranges this can be done by pulling the burner up and out of its plug-in receptacle. Other models have the burner directly wired to the cook top. To remove this type of burner, undo the screw that secures the burner to the cook top, remove the clips that secure the insulators to the burner terminals, and carefully unscrew the wires from the terminals. Take care not to bend these terminals.


  3. Visually inspect the burner - often there will be small holes or bubbles on the surface of a defective element.


  4. Now that you have removed the burner, you can test it using your VOM. Using the ohmmeter function, set the range scale to R x 1 and touch the test leads to the two burner terminals. The VOM should show continuity. Typical burner readings should be somewhere between 19 and 115 ohms, depending on the range manufacturer. If there is no continuity, the burner is defective. To test for a grounded (or shorted) burner, place one test lead on the outside surface of the burner and the other test lead on each burner terminal in turn. If there is continuity at either terminal, the burner is defective.


  5. If the burner is defective, replace with a new one by reversing the removal procedure (step 2 above). If replacing a wired-in burner, make sure that you install the wires on the correct terminals, according to the wiring diagram.


REMEMBER YOU ARE WORKING WITH 220 VOLTS - USE EXTREME CAUTION!!!

The flashing may indicate a failed power supply. Or a bad backlight tube.

Only 3 months old? Any warranty?

Considering its age I would say a defective part or poor assembly is to blame.

You could try a little oven cleaner on it. That should take care of the mark. After that, if it did not work, clean off the oven cleaner well and then try a bleach solution.

I have a Schott Ceran cook top that is marred with black stains all over the burners. The stove works, but looks awful. How much would it cost to replace top? The marks seem to be appearing from the bottom...


Use oven cleaner. Spray it and let it sit on a couple of hours. Scrape with a razor blade. It worked for me after trying everything recommened by the manufacture.

REPLACE CRACKED GLASS COOK TOP


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:

http://www.fixya.com/support/r391448-replacing_glass_cook_top

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.

GE cooktop has porceline "popping" off literally.


Porceline (a coating over metal in this case) is actually a type of glass, and subject to fracture upon sudden thermal shock or physical stress. The part you indicate is WB62T10124 for a JGB939C1WW probably a bit over $150 or a WB62T10132 for a JGP939C2WW, probably a bit over $100, but the labor to replace it would be costly. If you rate this, please remember I did not manufacture this product, nor am I a GE employee, so please don't shoot the messenger.

Replacement of glass top


Check your warranty in the back of your use and care book. If the unit was manufactured prior to 1/1/06 it may have a five year part (not labor) warranty as long as you did not physically abuse it. The glass top comes as an assembled top (glass, the black seal, and the metal frame holding it)
Disconnect power. remove screws under the front edge of cook top. lift cook top and remove crossbars holding burners up against glass top. Unhook cook top / frame assemble. Install new top in reverse order.
