Larry Q Easton , CT December 23, 2014 Appliance: LG Electric Range LRE30451SW Lg Range Lre30451sw / Awhelga: My stove control panel started flashing (f 1) error code. How to replace Service Parts. I took back off stove and determined touch pad panel must be bad...unfortunately for me the part was out of stock, took APP a week to get part and as it was 3 weeks before Christmas (delivery took a little longer than normal) took a week. I immediately began installation and it went well, took 20 mins. for all the screws, plugged in and everything worked great. 6 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
