What This Error Means
F35 on a GE oven means the control board is seeing a bad signal from the oven temperature sensor (also called the RTD probe).
In plain terms: the oven can’t trust its temperature reading, so it throws an error and usually kills the heat.
Official Fix
Do this with power off. You’re working around 240V here.
- Kill power at the breaker, not just the oven controls. Wait a minute for everything to discharge.
- Let the oven cool fully if it was recently hot. You need room-temperature readings.
- Open the oven door and find the temperature sensor: a thin metal rod sticking out of the back wall, usually upper left or upper right, held by two small screws.
- Remove the two screws and gently pull the sensor tip toward you until the wire connector appears through the insulation.
- Separate the connector carefully. Don’t yank the wires. Inspect both sides for burnt spots, loose pins, or corrosion.
- If you have a multimeter, set it to ohms (Ω) and measure across the two sensor leads. A good GE oven sensor should read roughly 1050–1100 Ω at room temperature (around 70°F).
- If the sensor is open (infinite), near 0 Ω, or way out of range, replace the sensor. It’s a simple swap: old one out, new one into the same connector, tuck the wires back, reinstall the screws.
- If the sensor reading is good, inspect the harness from that connector back to the control board:
- Pull the range out a bit, remove the back panel (power still OFF).
- Find the sensor wires going to the control board (usually two small gauge wires, often violet or similar color).
- Check for cuts, burns, or melted insulation. Repair or replace damaged wiring.
- Reseat the sensor connector at the board. Make sure it’s fully locked in.
- Restore power at the breaker and test the oven:
- Clear the error by hitting Cancel/Clear.
- Set Bake to 350°F and see if F35 comes back.
- If the sensor and wiring are solid but F35 comes back quickly, the electronic control board (ERC/clock) is usually the culprit and has to be replaced or professionally rebuilt.
The Technician’s Trick
What the book doesn’t tell you: a lot of F35 calls are just ugly connectors, not bad sensors or boards.
- With power OFF, pull the range out a foot so you can get behind it.
- Pop the rear cover. Find the sensor connector where the small wires from the oven cavity meet the harness to the control board.
- Unplug that connector, spray a tiny bit of electrical contact cleaner (or at least blow the dust out), and plug it in and out a few times to burnish the contacts.
- Gently pinch female terminals tighter (if you know what you’re doing) so they grip the pins better. Loose fit = intermittent F35.
- Do the same reseat on the control-board end of the sensor plug.
- Put the back on, restore power, and run the oven. If F35 disappears and stays gone, you just fixed it for the price of your time instead of a new board.
If you’re not comfortable working around live 240V, don’t do any powered tests. Stick to cold checks and replacements only.
Is It Worth Fixing? (The Financial Verdict)
- ✅ Fix: Sensor or wiring issue on a GE oven under ~12 years old; parts are cheap and the job is straightforward for a careful DIYer.
- ⚠️ Debatable: Oven is 12–15 years old, needs a control board plus other work (burnt terminals, failing elements); compare total repair cost to a mid-range replacement.
- ❌ Replace: Control board is obsolete or costs more than half the price of a new comparable oven, or the unit has multiple major problems (cracked liner, bad door hinges, failing elements).
