GE Oven F28 Error Code Fix (Control Board Communication Fault)

Here’s the straight, “by-the-book” approach that GE expects:

• 1. Kill the power first.
  • Go to the breaker panel.
  • Turn the oven’s breaker OFF (usually a double 30–50A breaker).
  • Leave it off for at least 2–3 minutes to fully drain the control board.
• 2. Power it back up and test.
  • Turn the breaker back ON.
  • Wait for the oven to boot.
  • Try a simple Bake at 350°F.
  • If F28 never comes back, it was probably a one-time glitch from a power blip.
• 3. If F28 comes back, inspect the wiring between the boards. (Oven still OFF at the breaker.)
  • Pull the range out a few inches, or open the upper panel on a wall oven.
  • Remove the back cover or control panel cover to access the electronics.
  • Find the user interface board (behind the keypad/touch glass) and the main control board (bigger board with relays).
  • Locate the harness/ribbon that runs between them.
  • Unplug each connector one at a time, check for:
    • Burn marks or melted plastic.
    • Green/white corrosion on pins.
    • Pins pushed back or loose in the plug.
  • Firmly re-seat each connector until it clicks or feels fully home.
  • If a harness is nicked, pinched, or brittle, the manual says: replace the harness.
• 4. Check for heat damage around the control area.
  • Look for browned board areas, cracked solder at big connectors, or a cooked smell.
  • If any of that shows up, the official call is: replace the affected board.
• 5. Replace the failing control.
  • If wiring looks clean and tight but F28 returns immediately:
    • GE’s flowcharts usually say: first swap the user interface (UI/touch panel), retest.
    • If F28 is still there, replace the main control board (EOC/clock).
  • Match your model number off the door frame sticker when ordering parts.
• 6. Safety note.
  • This is 240V. If you’re not comfortable working around live wiring or pulling an oven, stop and call a pro once the power-reset fails.
