GE Oven F36 Error Code Fix Guide

by

What This Error Means

F36 on a GE oven usually means: Oven temperature sensor circuit fault.

Translation: The control board thinks the oven temperature sensor or its wiring is open, shorted, or just not believable, so it shuts the heat down and throws F36.

  • Oven will not start bake or broil, or quits mid-cycle.
  • F36 pops up and it may start beeping.
  • Fans and lights may still work, but no heat you can trust.

Different GE models name it slightly differently, but it all comes down to the sensor circuit between the oven and the control board not checking out.

Official Fix

Here is the straight-from-the-manual style path, trimmed of fluff.

  • Kill power first.
    Flip the range or wall oven breaker OFF. Leave it off at least 1 minute. This hard-resets the control.
  • Turn power back on and test.
    Turn breaker ON, try Bake. If F36 never comes back, it was a glitch. If it comes back quickly, keep going.
  • Find the oven temperature sensor.
    Inside the oven, look at the back wall for a skinny metal rod, usually upper left or center, held by two small screws. That is the temperature sensor.
  • Pull the sensor and check the connection.
    • Breaker OFF again.
    • Remove the two screws holding the sensor.
    • Gently pull the sensor toward you a few inches until the wire connector appears.
    • Unplug the connector, look for burned, loose, or corroded pins, then plug it back in firmly.
  • Meter the sensor if you have a multimeter.
    • Set meter to resistance (ohms).
    • Room temperature sensor should read around 1000–1100 Ω (roughly 1080 Ω at 70 °F).
    • If it reads open (OL), sky-high, or just a few ohms, the sensor is bad. Replace it.
  • Inspect the sensor wiring harness.
    • Follow the two sensor wires as far as you can see from inside or from the back (on a slide-in/range you may need to pull the unit out a bit).
    • Look for melted insulation, pinched spots where it passes through metal, or chewed wiring.
    • Repair or replace damaged wiring and connectors.
  • If sensor and wiring test good, suspect the control board.
    • With a good sensor (around 1000–1100 Ω) at the board connector and no wiring breaks, the electronic oven control is usually the culprit.
    • The official fix then is: replace the control board (also called ERC or clock/control).
  • Final test.
    Restore power, run Bake to 350 °F. If the oven heats normally with no F36, you are done.

If your exact manual says F36 is tied to a specific cavity (upper vs lower oven) or meat probe, the process is the same: sensor or probe, wiring, then board.

The Technician’s Trick

Here is how a field tech separates sensor vs board without just throwing parts at it.

  • Do a serious connector reset.
    • Breaker OFF.
    • Unplug the sensor connector and the matching plug on the control board end (you may have to pull the oven out and remove the top or back cover).
    • Spray a tiny bit of contact cleaner (if you have it) or just plug/unplug each connector 3–4 times to scrape oxidation off.
    • Make sure the pins are tight, not loose or pushed back.
  • Fake the sensor with a resistor (test only).
    • This is the pro move. Breaker OFF.
    • Unplug the oven sensor from the control board.
    • Grab a 1 kΩ to 1.1 kΩ resistor (1/2 watt or higher).
    • Stick the resistor leads into the two sensor terminals on the control board connector (make solid contact, no shorts to chassis).
    • Restore power and see what happens.
    • If the oven now powers up without F36 and will start a Bake cycle, the control board is happy. Your problem is the real sensor or its wiring, not the board.
    • If F36 still shows with the resistor in place, the control board itself is bad.
    • Kill power and remove the resistor after testing. Do not cook with that in place; it is only a diagnostic trick.
  • Wiggle test for intermittent F36.
    • If F36 comes and goes, start Bake with the back cover off (power on, stay clear of live parts).
    • Gently wiggle the sensor harness and connectors.
    • If F36 pops when you move a certain spot, you have a cracked wire or loose terminal right there. Repair that instead of buying a board.

Is It Worth Fixing? (The Financial Verdict)

  • ✅ Fix: Sensor or wiring issue on an oven under about 15 years old; parts cost under roughly 100–150 dollars and the oven is otherwise in good shape.
  • ⚠️ Debatable: Needs a control board in the 200–400 dollar range on a 10–15 year old mid-range unit; worth it only if the oven is clean, cabinet fit is perfect, and you like how it cooks.
  • ❌ Replace: Oven is 15–20+ years old, needs a control board plus other work (burners, glass, door, etc.), or the repair quote hits more than about half the cost of a comparable new range or wall oven.
