FIXED LRG4115ST - Oven shuts off after 1 minute, plays tone, no error message

I have an LG LRG4115ST gas range that the oven will no longer turn on and stay on. When I turn it on (either convection or non - same result), It comes on for exactly 1 minute, I hear it ignite, then it plays a tone (recording attached) and shuts off. It does not display an error code. The broiler and range top both work. We tried replacing the igniter but that did not solve the issue.

I had a problem 1 1/2 years ago with it not maintaining temperature, and I think the repair guy replaced the thermostat. But now it won't even heat up. It's a month wait to get the repair guy in here and was hoping someone might know the solution.

Super. Thank you. It showed F7 & F9 error codes. I cleared them, tried restarting the oven (with the same issue I've been having, as expected). I checked the codes again and it's now only showing F7 error, so I wonder if replacing the igniter cleared the F9 error? I'll troubleshoot the F7 error now.

Thanks bigbuck.

Do you you hear your convection fan motor running?

F7--->Conv. Fan Motor Open
During cook, if convection fan does not operate while 1 minute (cumulative time) in the period of convection fan operation.

Check:
1. Wiring
2. Motor’s Resistance

Your model uses this convection fan motor: EAU62343001 - Fan Motor

I wonder if replacing the igniter cleared the F9 error?

Yes, F9 is usually a bad BAKE glow bar igniter or bad oven sensor.

Here's the BAKE glow bar igniter for your model, in case others need it too:
MEE61841401 Ignitor

Update: I changed out the convection motor and the oven is functioning again. Thank you for your assistance!
