Maytag Oven Error Codes — F1, F2, F3, F5, F9 Diagnosis & Fix
Maytag ovens display alphanumeric error codes when the control board detects a fault. Understanding what each code means lets you pinpoint the failed component before ordering any parts — saving both time and money. The most common codes fall into four categories: control board faults (F1), temperature-related faults (F2, F3), door latch and lock faults (F5, F9), and communication or sensor faults. In many cases, the first step is a power reset — unplug the oven for 5 minutes, then restore power. If the code clears and doesn't return, a transient voltage spike was the likely cause. If the code returns within a few cycles, the underlying component needs attention. The control board WP74009141 is the electronic brain of the oven. F1 codes typically indicate an internal control board fault — either a failed relay, corrupted memory, or a damaged component on the board itself. The temperature sensor WP74009778 is a resistance-based probe inside the oven cavity; F3 codes point directly to this sensor or its wiring. The door latch motor assembly WP74005788 handles both the door lock for self-clean cycles and the door position sensing; F5 and F9 codes indicate it cannot complete its travel. Always unplug the oven before inspecting or replacing any components. The 240V circuit in a range poses a serious electrocution risk.

Common Symptoms
- Error code displayed on oven control panel
- Oven beeping continuously with code shown
- Oven won't start or heat with error displayed
- Code appears during or after self-clean cycle
- Control panel unresponsive after error code
Most Likely Causes
- 1
F1 — Control Board Fault (WP74009141)
An F1 error on Maytag ovens indicates the electronic control board WP74009141 has detected an internal fault — typically a failed relay, corrupted EEPROM, or damaged control circuit. The board manages all oven functions including temperature regulation, timer, and display. A power reset (5-minute unplug) clears transient faults; if F1 returns, the control board must be replaced. Inspect the board for burn marks, cracked solder joints, or swollen capacitors before ordering a replacement.
- 2
F2 — Oven Over-Temperature
F2 indicates the oven has detected a temperature above the safe operating threshold (typically above 590°F/310°C for normal cooking, or above 990°F/530°C during self-clean). This can result from a stuck relay on the control board that holds the bake or broil element on continuously, a failed temperature sensor WP74009778 sending false readings, or a genuine runaway condition. Reset power and test the temperature sensor resistance before replacing the control board.
- 3
F3 — Temperature Sensor Fault (WP74009778)
F3 (sometimes F3E0 or F3E1 on newer models) indicates an open or shorted temperature sensor circuit. The sensor WP74009778 is a negative temperature coefficient (NTC) resistor that changes resistance with temperature. At room temperature (70°F/21°C), it should read approximately 1080 ohms. An open circuit (OL on multimeter) or near-zero reading indicates a failed sensor or broken wiring. Pull the sensor from the back wall of the oven cavity and test its resistance before replacing.
- 4
F5 / F9 — Door Latch Fault (WP74005788)
F5 and F9 codes indicate the door latch motor assembly WP74005788 cannot complete its lock or unlock travel. F5 typically appears when the door latch fails to lock during a self-clean cycle; F9 indicates the door won't unlock after self-clean. Common causes include a seized latch mechanism (food debris or warped latch arm), a burned-out latch motor, or a broken door lock switch. Try canceling the cycle, letting the oven cool for 30 minutes, then unlocking manually before replacing parts.

Quick DIY Checks
Unplug the oven or shut off the 240V circuit breaker before accessing any internal components — never work inside a live range.
If the F2 code appeared with smoke or burning smell, do not use the oven until the root cause is identified — a stuck relay can cause a fire.
After an F9 door-lock fault, let the oven cool completely (at least 30 minutes) before attempting to manually release the door latch — residual heat inside the cavity can cause burns.
- 1Power reset first — unplug the oven or trip the circuit breaker for 5 full minutes, then restore power; if the error code doesn't return within 1–2 cycles, a transient fault caused it and no repair is needed
- 2Identify your error code — F1: control board WP74009141 fault; F2: over-temp (check sensor first); F3/F3E0/F3E1: temperature sensor WP74009778 open or shorted; F5: door latch WP74005788 failed to lock; F9: door latch failed to unlock
- 3Test temperature sensor WP74009778 — unplug oven, remove back panel, disconnect sensor connector, measure resistance at sensor terminals; room-temp reading should be 1050–1100 ohms; OL or near-zero = replace sensor ($25–$45)

Repair vs Replace
Error codes almost always resolve to a single failed component — sensor, latch, or control board. All three are replaceable DIY parts. Only consider replacement if the control board fails and the oven is over 10 years old, or if multiple components fail simultaneously.
Est. Repair Cost
$25–$200 DIY (sensor WP74009778 $25–$45, door latch WP74005788 $60–$100, control board WP74009141 $120–$200)
Est. Replacement Cost
$900–$2,000 for a new Maytag range or wall oven

Frequently Asked Questions
- How do I clear an error code on my Maytag oven?
- Press the Cancel or Off button to clear the current error display. For a full reset, unplug the oven or trip the circuit breaker for 5 minutes, then restore power. If the code reappears within a few cycles, the underlying component has failed and must be repaired. Clearing the code without fixing the cause is a temporary measure only.
- What does F3 mean on a Maytag oven?
- F3 (or F3E0/F3E1 on newer models) indicates an open or shorted temperature sensor circuit. The temperature sensor WP74009778 monitors the oven cavity temperature. At room temperature it should read approximately 1080 ohms. Pull the sensor from the back wall of the oven cavity and test with a multimeter — if it reads OL (open circuit) or near-zero ohms, replace the sensor. Also inspect the wiring between the sensor and the control board for breaks.
- My Maytag oven shows F9 and the door is locked — how do I open it?
- F9 means the door latch motor WP74005788 failed to unlock after a self-clean cycle. First, let the oven cool completely for at least 30 minutes — the latch won't release while the cavity is hot. Then press Cancel and wait 30 seconds. On many models, cutting power for 5 minutes will reset the latch motor and allow it to retry. If the door remains locked, the latch assembly must be replaced — do not force the door, as this can damage the latch mechanism.
