Error codeF31
ApplianceRange
Quick answer
F31 on a legacy Dacor ER range means an open temperature sensor or open sensor wiring.
Model compatibility: Dacor reuses codes across series and model years, so F31 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Open temperature sensor or open sensor wiring.
F31 on a Dacor range means the temperature sensor circuit is open: either the sensor itself or its wiring. The code is in the control panel error list of the Technical Manual for the ER30D, ER36D and ER48D ranges, a legacy line.
What the manual lists
An open sensor gets the remedy replace the sensor. Open sensor wiring gets the remedy replace the sensor wiring. Treat both as technician work. Owner checks stay simple: the main power switch and whether the control panel is locked.
F3: external fault location, normally followed by a specific code.
