In brief
Jenn-Air documents F1-H as a possible problem with the oven temperature sensor, the control or the associated wiring. The sensor tells the control how hot the oven is; without a reading it can trust, the control usually stops heating. Do not use the oven until the code is cleared and stays clear.
Error codes
Reference| Code | Meaning |
|---|---|
| F1-H | There may be a problem with the Oven Temperature Sensor, the Control, or the associated wiring. |
What you observe
- The code first appeared after a self-clean — The oven worked before the clean cycle and has raised the code since.
- An element runs without cycling off — A control that reads the cavity as cold keeps heating; if you see this, switch off at the breaker.
- NEAR MISS: the cavity never warms at all — No heat and no sensor code points at the heating element or its supply, a different fault.
Likely causes, ranked
- Sensor wiring damaged by heat or pinching — Ranked first when F1-H first appeared after a self-clean: the clean cycle runs the cavity far hotter than baking, and the sensor's wiring and connector take the brunt of it.
- A failed or drifting oven temperature sensor — A sensor that reads wrong, or not at all, is the most direct way to produce this code, and it is a part that wears.
- The sensor connector behind the oven — The sensor plugs into the harness at the back wall; a connector pulled half off, corroded or heat-darkened breaks the reading.
Diagnostic order, cheapest and safest first
- Check what came before — A code that started after a self-clean or after the range was moved points at heat or pinch damage to the sensor wiring.
- Look at the probe in the cavity — With the oven cool, find the probe near the top rear of the cavity and check it stands clear of the wall and is not bent or loose.
- Reset and note the timing — Power-cycle at the breaker, preheat once, and note whether the code returns at once or only when hot.
Clearing the code and safe checks
- Reset the control — Switch the oven off at the breaker for a few minutes, then back on.
About 5 min
- Record when it happens — Note whether the code appears at preheat, mid-bake or after a clean; it decides the order of a technician's tests.
Tools: notebook or phoneAbout 2 min
- Stop before any panel comes off — Everything past this point needs live measurements or a panel removed; that is the line between an owner check and a service call.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. The sensor probe sits inside a cavity that stays hot long after cooking, and its connector is behind the oven next to live terminals; inspect only the visible probe, with the oven cool and off at the breaker.
When it is a service call
Call for service if F1-H returns after a reset, or at once if the oven keeps heating with the code showing or runs far hotter than its setting. Measuring the sensor and its harness against the model's specification is the test that decides the repair, and it needs a meter and the oven's rear connections.

What this reading does not cover
Generalized information: F1-H is read here for the Jenn-Air oven line as a whole, which fits Jenn-Air ovens whose code list carries F1-H as a temperature-sensor fault. It is not a reading for meat-probe codes, microwave and cooktop sensor codes, and models that read F1-H differently. Model lines can reuse a code with another meaning, so a model-specific page, where one exists, comes first.
