It took me about 20 minutes to install because i have already had LG junk range out and back in 7 times before tryign to fix issues (this is after warranty work came out 3 times). Slow start, no start, won't build heat fast, over temp once going. Warranty work replaced ignitor no change, readjusted ignitor location, replaced this gas valve before, no change. finally I replaced the thermostat (temp sensor), and the gas valve, and after 1.5 years the oven is finally, finally working like it should have from day 1. thank you!!!!!!
