Katie for Model Number LGGF3043KFR Studied the online material for this Gas range. It's run on Propane/LP. Tank is 40% at present, range TOP burners run fine, BROILER operates solo, but has a 2+" flame length when Frigidaire says it OUGHT to be 1". Different issue than I am looking to correct atm. PRESENT ISSUE; I have replaced the (bottom) BAKE igniter because of VERY slow pre-heat. NO JOY. Pre-heat to 450 STILL takes 39 minutes. THE Flame Length (FL) is approximately 3/8" on Bake tube, NOTHING like the advised 1" FL that is SUPPOSED to be seen at 300 F when Troubleshooting. 1) The UPPER Broil tube IS NOT ignited during BAKE cycle and SOME information online CLAIMS there SHOULD be BOTH upper and lower burners during BAKE??? Which is it, please. Both Bake and Broiler tubes or JUST Bake igniter and tube. 2) HOW do I adjust the FL to get it to the preferred 1" vs the present 3/8" FL? 3) ALSO had an intermittent, LOUD HISSING sound that seemed to occur about every 10 minutes for 3 minutes then "quiet down" again while baking an apple pie. DID NOT hear this sound during entire 39 minute, troubleshooting pre-heat to 450 degrees this morning.
Answer Katie, a low flame can influence how long the oven takes to heat up. This can be caused by partially blocked jets, or even a partially closed air shutter. It would be recommended that the burner is thoroughly cleaned and that the air shutter is as fully open as possible. When bake is set, a gas range would only utilize the burner that a cycle is set to. Read More... Answered by AppliancePartsPros.com | Thursday, October 5, 2023
