What F3 or F3-1 Means
Maytag publishes F3 on the legacy platform as a possible problem with the oven control or the associated wiring, and F3-1 as a possible problem with the oven temperature sensor, the control, or the associated wiring. The suffix shifts the emphasis towards the sensor.
Common Causes of F3 or F3-1
- Oven control fault
- Oven temperature sensor failed
- Sensor connector loose
- Wiring damaged behind the range
🔧 One Safe Check You Can Try
Press Cancel to clear the code, then cut power at the breaker for a minute, restore it, and start a bake cycle to see whether the code returns. Check the sensor probe inside a cool cavity is secure and not touching the liner, which addresses the F3-1 reading. If the plain F3 returns, the control is the target. Note which of the two appeared, because here the suffix genuinely changes what gets tested first.
⚠ Why You Shouldn't Go Further Than That
- A range is wired to a high-current circuit, and the control is behind a panel with live terminals.
- On a gas range the burner and gas connection sit in the same space as the control wiring.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
