20 Most Recent LG LRE30451 Electric Kitchen Range Questions & Answers


LG had a recall awhile back because the control panel touch control switch was right over the oven vent (on the right side) and use of the oven made it randomly cycle lock/unlock+ ding all night long for weeks.
Throwing the breaker off for the night was the only recourse, besides having LG replace the control panel.

I found that it would eventually fix itself (!), but come back at some point here and there, and then disappear weeks later.

The lock and unlock works well for the 4 - 5 button problem. However the "start" button failure is another problem altogether. I had this problem and found that the ribbon connector attaching the membrane switches to the circuit card (PWB) is where the problem lies. The ribbon cables (two of them) are connected by a pressure contact connector mounted on the PWB. This connection method is less than robust. the fix is to pull the ribbon from the connector, clean it carefully with a paper towel and some alcohol, and reconnect it. To remove the cable the connector has a small flange that pops up about .05 inch whn you pull on the connector. Once it pops up gently pull the ribbon cable out of the connector. To replace it just push the ribbon back into the slot on the top of the connector and snap the flange back down. I strongly suspect this connector will get dirty again every couple years as the oven vent fumes are not properly prevented from partially passing over the PWB right where these connectors are mounted.

Did they stop working after running the self-cleaning cycle? That is what happened to mine. I moved the oven and unplugged it. Left it unplugged for a few days waiting for repairman. He plugged it in when he got there, and everything worked. He advised against using the self-cleaning cycle because the heat can cause problems with the touchpad buttons.

F-9 is the "Oven too hot error".
When the oven reaches its temperature a switch is opened.
If this switch is defective it may stay closed and the oven will overheat.

Let it dry and then plug it in again. You may have a bad connection, if you didn't short something out while the alcohol was still wet. maybe check for a blown fuse?
