Symptoms
- Timer doesn't count down or count down is inaccurate
- Oven doesn't turn off automatically as programmed
- Delay-start feature doesn't trigger heating at the set time
- Display shows a countdown but the oven behaves differently
Likely causes
- CommonFeature not set up correctlyDelay-bake and timer features often require several exact steps in sequence to program correctly.
- CommonClock not set correctlyMany timer functions rely on an accurate current time to calculate delays.
- PossibleControl board glitchLike other electronics, a power reset can clear minor timing glitches.
- Less commonFailed control boardPersistent timer failures across multiple attempts can indicate a hardware fault.
What to do
- Confirm the current clock time on the display is accurate, and correct it if not.
- Re-read your manual's exact steps for setting a timer or delay-start, since the sequence of button presses matters and varies by brand.
- Try programming a short test timer (like 2 minutes) to see if basic countdown functionality works at all.
- Power-cycle the range at the breaker for about a minute if the timer misbehaves, then retry.
- Avoid relying on delay-start for perishable food safety until you've confirmed it works reliably in testing, since food left out too long before cooking can be unsafe.
- If the timer function still fails after a correct setup and a power reset, the control board likely needs professional testing.

When to call a pro
If the timer or auto-shutoff still misbehaves after confirming correct setup and a power reset, an appliance technician can test the control board.
