    What to do if my LG LRE3193BD oven element does not heat?
    • R
      reginaandersonAug 18, 2025
      If the oven element in your LG Ranges isn't heating, check the circuit breaker first. If that's not the issue, inspect and repair or replace any loose or bad wiring, consulting the wiring diagrams for guidance. Test and replace the element if necessary. A defective main PCB or relay PCB could also be the cause, so test and replace those components as needed.

      If your LG Ranges oven isn't operating, first ensure that there is power present at the unit and that the circuit breaker hasn't tripped. Also, check the household fuse capacity and replace it if necessary. If these steps don't resolve the issue, the main PCB may be faulty and require testing or replacement; refer to pages 9-1 through 9-3 for guidance.

    Why does my LG Ranges oven not bake (Selection is set for to BAKE or TIMED BAKE)?
    • C
      Cynthia BeanAug 23, 2025
      If your LG Ranges oven isn't baking when set to BAKE or TIMED BAKE, the possible causes include loose or bad wiring, a defective BAKE element, a defective electronic clock, or a door switch sensing error. To resolve this, verify all connections are clean and tight, and replace any broken wires. Test and replace the BAKE element if needed. Also, you may need to replace the main PCB or relay PCB. Check the door switch and the contact point between the door and the door switch.

      kristinarodriguezAug 28, 2025
      If your LG Ranges oven isn't starting or stops during the self-clean cycle, it could be due to bad wiring, a faulty latch system, a programming error, or a defective contact point with the door switch. First, repair or replace any faulty wiring. Then, check the door locking motor and micro switch. Try resetting the oven by switching off the circuit breaker for five minutes before turning it back on. Finally, test the door switch and check the contact point between the door and door switch.
