When the BAKE function for the Upper Oven is selected, the bake (lower) element will not heat, but the broil (upper) element heats continuously. The range does not display any fault codes.
The Owner's Manual indicates I should be able to download and use an app called LG ThinQ to use a "Smart Diagnosis" feature if my range has the Smsart Diagnosis icon. It has the icon printed in black on the control panel glass, but it's barely visible (not back-lit, etc.), and I never noticed it in the 15 months we've owned the range, until I started searching for it. I downloaded the app and tried to use it, but the iPhone displayed a message saying there was no Smart Diagosis feature available.
I've disconnected and tested the bake element at 22.3 Ohms; the tech sheet says it should be approximately 24 Ohms, so that doesn't look like a problem.
If I'm reading the tech sheet Relay Operation table correctly, it says that for the Upper Oven in the BAKE mode, there are three relays involved with the following operation:
Bake HTR RY5: Cycles on and off, but can also remain on.
Broil HTR RY6: Cycles on and off, but can also remain on.
DLB RY7: For preheating mode, the relay will always be turned on. After the oven reaches temperature, the relay will cycle on and off.
I'm going to try downloading/using the LG ThinQ app again and look around for the relay board to see if I can test the relay outputs when the BAKE function is selected.
Any info you can provide on the following will be extremely helpful:
1. Any tips on using the ThinQ app? Is it useful?
2. Anyone know where the relay board is? Under the back panel or inside the front control panel?
3. Are the individual relays replaceable or will I have to replace the entire board?
4. Does anyone have a part number for the board or the relays? A lot of online parts sites don't even show the model number.
Thanks,
Paul G.
