Mark G Olivette , MO December 06, 2020 Appliance: LG Electric Range LRE30453SW/00 Partial failure of keypad controls. Some burners worked, others could not be adjusted. some keypad numbers did not work Service manual (found online) indicated *probably* the main pcb, but *possibly* the membrane keypad assembly. Since our keypad assembly had yellowed and cracked in multiple spots (9 years old), we opted to replace both items simultaneously. Disregard directions in service manual. All that is needed to replace both items easily is to detach the top of the range (4 screws) which holds the keypad assembly and main pcb. Lay it face down on a towel and all screws are easily accessible. Replacement keypad assembly was a direct match. Replacement main pcb was a later version, with three connectors reversed (upside down) from old pcb, plus several connectors had received new labels. However, everything fit back easily (most only fit one spot, in one orientation). Everything seems to work again after the repair. Read More...
