What F6 means on your Dacor range (dacor range f6)
Dacor range f6 means the ERC’s stored configuration data — held in its EEPROM memory — has failed a checksum verification on a Legacy Dacor (pre-2016) range. That memory holds the calibration values the ERC needs to interpret the control panel, drive the relays, and read the oven temperature sensor correctly across both the oven and, on many models, some cooktop control functions. Dacor’s Tec-Line document lists F6 alongside F5 as one of the two range codes whose documented fix is ERC replacement, since the problem lives on the board’s memory rather than in any external wiring or sensor.
Symptoms
What follows helps you confirm that your Dacor range has this specific problem rather than one that merely resembles it on a range.
- F6 appears on the display, frequently at power-up.
- The range may behave erratically before settling into the problem, such as misreading the clock or misreading key presses on the panel.
- Both oven and some interlocked cooktop functions may be affected, since the EEPROM feeds the whole control system.
- F6 typically persists across power cycles rather than clearing.
- There is no external symptom like smell or noise since the problem is internal to the board’s memory.
Common causes
There is more than one road to F6 on a Dacor range, and the list below walks them in the order a technician would on your range.
- EEPROM checksum failure — the stored data itself has become corrupted, which Dacor’s documentation treats as an ERC-replacement problem.
- Power surge or brownout — a voltage event can corrupt EEPROM contents without any other visible damage.
- Aging memory cell failure — EEPROM cells can fail after many years of read/write cycles on an older range.
- Improper board servicing history — a prior repair that reflashed or reset the board incorrectly can leave a bad checksum.
- Manufacturing-defect memory cell — rare, but a marginal EEPROM cell can fail years after installation.
Troubleshooting steps you can try
Go down the list on your range and stop at the first step that makes you uneasy — a Dacor range is not worth an injury.
- Power-cycle the range once at the breaker to confirm the problem is persistent rather than a one-time glitch.
- Do not keep cycling power repeatedly — a genuine EEPROM checksum failure will not resolve itself.
- Note whether F6 appeared after a power outage, electrical storm, or any recent electrical work in the home.
- Avoid attempting any self-clean or extended bake cycle while F6 is displayed.
- Have your range’s exact model number ready, since the replacement ERC must match it precisely.
Parts a technician may replace
Depending on what the diagnosis shows, a technician may inspect, test, or replace the electronic range control board (eeprom memory). The right part for your Dacor range is matched from its model and serial number, and confirming which component failed keeps the range repair to what it actually needs.
When to call a technician
Like F5, Dacor’s own documentation treats F6 as a board-replacement problem on the range, so a technician confirming the checksum error and sourcing the correct ERC is the quickest fix. With a High-rated problem, continuing to run the range risks turning a repairable range into a replaceable one. We hold no affiliation with the manufacturer of your range; the parts are genuine and the labor is warranted for 30 days.
