What we can confirm
Code F9, 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
F9
The range cannot confirm the state of its own door latch. As on the Classic platform this usually appears around a self-clean cycle, and the sequence matters: a door that is currently locked on a hot cavity is left alone until it is cold, whatever the code says. The mechanism and the switch that reports its position are the two candidates, and they are cheap parts compared with the hinges that get bent when somebody forces a door.

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.
General external problem — the control has detected a problem outside itself.

About Range error code F9
What F9 means on this make
The range cannot confirm the state of its own door latch. As on the Classic platform this usually appears around a self-clean cycle, and the sequence matters: a door that is currently locked on a hot cavity is left alone until it is cold, whatever the code says. The mechanism and the switch that reports its position are the two candidates, and they are cheap parts compared with the hinges that get bent when somebody forces a door.
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
- If the door is locked and the oven is hot, wait. Nothing else on this list matters more.
- Once cold, power down for a minute — some latches release on a control restart.
- The latch motor and its position switch are tested separately.
- Have it repaired before the next cleaning cycle rather than after it.
Where this goes next
The job this usually becomes is self clean and door lock repair, 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.
