Maytag Range F3E0 Error: Temp sensor open circuit
What Does Maytag Range Error Code F3E0 Mean? F3E0 on a Maytag MGR gas range or MER electric range means the electronic oven control is reading an open circuit from the oven temperature sensor — the RTD probe mounted inside the cavity. An open circuit means resistance is effectively infinite, which tells the EOC it […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. Without a working temperature sensor the EOC cannot regulate oven heat. The oven will not function while F3E0 is active. On Maytag MGR gas ranges this means the igniter circuit is also disabled — the oven is safe from a fire standpoint but cannot be used for cooking until the sensor is replaced.
Can I reset the code?
No. F3E0 is caused by a hardware open circuit — no reset procedure will restore the missing sensor signal. The code returns immediately after every breaker reset until the sensor probe or harness is repaired or replaced.
When to stop immediately?
Stop if you notice: Oven does not heat at all after a breaker reset, Sensor resistance reads open (OL) or far out of range with a multimeter.
Symptoms You May Notice
Oven fails to heat at preheat
Elements or gas burner energize briefly then cut out within the first few minutes of any cook mode.
Display shows dashes or a static ambient temperature reading
Instead of a climbing temperature value during preheat, the control shows dashes or a fixed near-room-temperature reading, indicating no valid signal is reaching the EOC from the sensor.
Surface burners work normally; only oven functions are disabled
The F3E0 fault isolates to the oven-temperature circuit — gas surface burners on MGR models and electric surface elements on MER models continue to operate as expected.
Oven interior stays cold
After several minutes in Bake mode, the cavity remains at room temperature.
Possible Causes
Failed oven temperature sensor (RTD probe)
The resistance-temperature detector mounted on the upper-rear wall of the Maytag oven cavity has an open internal element, sending infinite resistance to the EOC board.
DIY PossibleBroken or disconnected sensor wire harness
The two-wire harness connecting the RTD sensor to the EOC board has a broken wire, corroded terminal, or connector that has pulled free — interrupting the circuit.
DIY PossibleDamaged EOC board sensor input circuit
If the sensor and harness both test correctly, the fault lies in the board's sensor-reading circuitry — a component-level failure requiring board replacement on the Maytag range.
Requires ProfessionalSafe Checks You Can Do
-
1
Measure sensor resistance with a multimeter
Unplug the Maytag range, locate the RTD probe on the upper-rear oven cavity wall, disconnect its two-wire harness, and measure resistance across the sensor terminals. A healthy sensor reads approximately 1,080–1,090 ohms at room temperature (68°F).
An open-circuit reading (OL or infinite resistance) confirms sensor failure — replacement sensors for Maytag MGR and MER models are typically from $20 and are owner-installable on most freestanding configurations.
Tools required -
2
Inspect the sensor wire harness for damage
Trace the two-wire harness from the sensor probe to the EOC board connector. Look for burned insulation, broken wires, or a connector that has pulled free from its lock tab at the board.
On Maytag MER electric slide-in models the harness passes through the rear oven wall and flexes slightly each time the door is opened — a break near the connector grommet is a common failure point.
When to Call a Professional
Contact a qualified technician if:
- Sensor resistance is within spec but F3E0 persists — indicates a faulty EOC board input circuit
- Harness damage is inside the oven cavity wall and requires panel removal
- Model is under the Maytag limited warranty and the sensor is an in-warranty failure
