Quick answer: A failed GE oven control board causes erratic temperature, error codes (F1/F2/F3), or complete dead display. Diagnostic: test elements first (cheaper) — if elements OK and oven still won't heat, board is suspect. Replacement cost $140-$200, 60-90 min job.

Most likely sign: Display works but elements never get power, OR display dead with breaker fine.
Difficulty: Medium — requires removing rear access panel.
The GE oven control board (also called electronic range control or ERC) interprets your settings and signals elements/igniter. When failed, the oven becomes unpredictable.
Symptoms of a failed control board
- F1, F2, F3 error codes persisting after element replacement
- Display dead but breaker is OK and door switch tested good
- Temperature erratic — oven runs 50°F+ off setpoint
- Oven won't preheat but elements test good (multimeter ~20 ohms)
- Burn marks visible on board (remove rear panel to inspect)
How to diagnose
- Test bake element first — multimeter should read 15-25 ohms. If infinite, replace element ($60-$100), NOT board.
- Test broil element similarly.
- Test temperature sensor (~$30 to replace) — it's the simpler component.
- Only AFTER ruling out elements + sensor → suspect board.
The fix
Replace control board. OEM WB27X45466 (newer GE) or model-specific. Typical price $140-$200. Difficulty: Medium — 60-90 min job, mostly removing the rear panel and 8-10 wire connections.
Critical: Photo-document wire positions BEFORE disconnecting. Reverse install order.

Frequently asked questions
Q: Is repairing a $200 board worth it vs new oven?
A: Yes if oven < 12 years old. New oven $800-$2000 vs $200 board + 90 min DIY.
Q: Can I reset the control board to fix temporarily?
A: Yes — flip breaker for 30 sec, restore. Sometimes resets glitches. Lasts hours-weeks before recurring.
Q: How long should a control board last?
A: 8-12 years. Heat exposure + power surges shorten lifespan.
Q: My GE has SmartHQ — is the board different?
A: WiFi-enabled boards cost $230-$300. Same install procedure.
Q: Should I install a surge protector after replacement?
A: Yes — surge during electric storm is #1 cause of board failure. $30-$50 dedicated appliance surge protector.
