Maytag range F1E7: control board temperature sensor fault
F1E7 means the temperature sensor built onto the main control board is reading outside its possible range, so the control locks up.

What the range is detecting
The control watches its own board temperature with an on-board thermistor. A reading that is impossibly hot or cold means the sensor is open or shorted, and the control stops with F1E7.
Causes listed for this condition
In the order the service documentation checks them. Documented causes come from the manufacturer's service documentation for these platforms; possible causes are based on how the system works; unconfirmed marks common assumptions that the documentation does not support.
- Documented A failed on-board temperature sensor, which is part of the main control.
- Possible Real overheating of the control area, for example from blocked cooling airflow.
Safe checks you can make
- Make sure nothing blocks the oven vent openings or the air gaps around the control panel, such as pans, foil or towels.
- Switch the oven off at the circuit breaker (or unplug it if the plug is easy to reach) for about one minute, restore power, and see whether the code comes back.
Further diagnosis requires opening the appliance. Beyond the owner checks, diagnosis involves removing panels, testing components and checking wiring. We describe what a technician investigates, not how to do it yourself.
What a technician checks
- Checks whether the control area is actually overheating (cooling fan and airflow).
- Replaces the main control when the on-board sensor is at fault.
Typical repairs and cost
Depending on what diagnosis finds, this code can lead to one of these repairs:
| Repair | Typical range | Labor |
|---|---|---|
| Range control board replacement | $300–$720 | Moderate |
Typical total ranges for the Las Vegas area, parts and labor included. The final cost depends on diagnosis, the exact model, parts availability and whether other damage is found.
Can you keep using it?
Use with caution. The control may lock out some or all cooking functions. A power reset may clear the code for a while; if it keeps coming back, the control system needs diagnosis rather than repeated resets.

Repair or replace?
A fault code alone rarely justifies replacing a range. Most F1E7 repairs involve a single component once diagnosed. Replacement becomes worth considering when the unit is near the end of its typical 13–17-year life and the diagnosed repair is a major one. See the repair-or-replace guide.
