Error code
Range error code F3
Dacor range error code F3: The counterpart to F1: something the control depends on is not behaving, and the problem is out in the appliance rather than in the board. Which machines can raise it, what the maker publishes about it, and what to do next.

What we can confirm
Code F3, from the manufacturer's own documentation
A code is only meaningful together with the machine showing it — the same digits mean different things on different equipment.
The code
F3
The counterpart to F1: something the control depends on is not behaving, and the problem is out in the appliance rather than in the board. In practice this points at the wiring, a switch or a component the control watches, and the diagnosis is a matter of following what the board can see. It is not, on its own, a reason to buy a control panel — and on this make the same string is a shorted temperature sensor on the Classic ERC platform.

What it narrows down to
General external problem — the control has detected a problem outside itself.

On the same appliance
What else belongs to the ranges
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.
Other codes this appliance can display
Shorted or jammed input device — a shorted wire or a failed membrane switch.
System watchdog circuit — the ERC's own self-diagnostic found a bake or broil system failure.
Heating mode high temperature — the control detected a runaway heat condition.
Shorted oven temperature sensor.
Open oven temperature sensor circuit.
ERC self-diagnostic failure — the control has failed its own test.
EEPROM checksum error — the control's stored settings no longer verify.
Door lock enabled above temperature — the clean-lock or phase circuit is faulty.
Door locking switch — the motor ran for two minutes without the phase switch changing state.
General internal problem reported by the range control.
Communication problem between the control panel and the relay board.
Door lock problem.

About Range error code F3
What F3 means on this make
The counterpart to F1: something the control depends on is not behaving, and the problem is out in the appliance rather than in the board. In practice this points at the wiring, a switch or a component the control watches, and the diagnosis is a matter of following what the board can see. It is not, on its own, a reason to buy a control panel — and on this make the same string is a shorted temperature sensor on the Classic ERC platform.
Where this appears, and which table it belongs to
On the appliance's own display. Photograph it before you cut the power: a display that has been cleared has taken the evidence with it, and there is no way to ask the machine for it again. Then check the model, because this make changed hands in 2016 and the two generations share no code string. The same characters mean different things on a Classic ERC oven, an ER-series range and a Modernist induction cooktop, and a meaning read off the wrong table is worse than no meaning at all.
Which machines this one applies to
ER30D, ER36D and ER48D ranges. The same number on a different appliance of this make is a different page and often a different repair, which is why this archive is organized by appliance rather than by number. This maker documents codes on 5 of the appliance types this site publishes — coffee machine, cooktop, dishwasher, oven and range — and publishes none at all for freezer, microwave, range hood, refrigerator and wine cooler. Those appliances have symptom pages here and no code pages, which is the honest answer rather than borrowing a table from the machine next door.
What to do about it
- Note the model. F3 is an external problem here and a shorted sensor on the Classic ovens.
- Describe what the range was doing when it appeared — baking, cleaning, or idle.
- The harnesses and switches the control monitors are checked before any board is considered.
- An intermittent F3 is usually a connection rather than a component.
Where this goes next
The job this usually becomes is legacy control diagnosis, and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call (305) 363-6067 and describe what the panel is doing before booking anything.
