Dacor cooktops
California-born cooking, with a published code table.
Dacor cooktops span two eras: the Samsung-era Contemporary and Transitional induction tops with an officially documented information-code table, and the legacy gas platforms that speak through burners, not displays. Both dialects are honest - and both are decoded on-site, not guessed.
A photo of the model label and the complete installation helps the team understand the configuration before the visit.
Induction
Contemporary DTI-M
30 and 36-inch LCD induction cooktops (DTI30M977, DTI36M977) with Wi-Fi and flex zones.
Induction
Transitional DTI-P
Knob-accented induction tops (DTI30P876, DTI36P876) on the same code platform.
Gas
DTG / rangetops
Transitional gas cooktops and DTT rangetops - sealed burners, mechanical by design.
Legacy
Distinctive / Renaissance
Pre-2016 gas tops (SGM, RNCT and kin) still common in San Diego kitchens.
Start with the symptom
Common Dacor cooktop problems
A symptom narrows the inspection; it does not identify the failed component. The $99 visit confirms the actual fault on the exact model before any repair is authorized.
Zones
Induction zone won't detect the pan
Ferromagnetic cookware and zone sizing first - the manual's own checklist - then zone electronics.
Zones
Two zones dead on one side
Induction power modules serve zone pairs - a documented, board-level repair.
Burners
Gas burner clicking forever
Moisture and cap seating on sealed burners - dry and reseat before parts.
Ignition
Weak or lazy flame
Orifice, regulator and air shutter territory on gas tops.
Controls
Touch controls unresponsive
The d0 pattern - keypad moisture, then touch electronics.
Surface
Cracked induction glass
Stop using the top; glass replacement is quoted honestly against replacement value.
Series and model numbers
Dacor cooktop series we service
The letter after DTI is the style collection; the code dialect is shared. On gas, the model number is the burner map.
Induction
DTI prefixes
Model numbers
DTI36M977BB, DTI30P876BB
What to note
M = Contemporary, P = Transitional - the code table applies across both.
Gas
DTG / DTT prefixes
Model numbers
DTG36P875, DTT48M976
What to note
Gas tops and rangetops - no codes, direct diagnosis.
Legacy
SGM / RNCT
Model numbers
SGM365, RNCT365
What to note
Legacy gas and induction platforms - the full model decides the parts book.
Model label
Where to find your Dacor model number
The data plate is on the underside of the cooktop, reached from the cabinet below; the installation paperwork usually carries a duplicate. Photograph the full model and serial before the visit. Photograph the complete label — the full model and serial identify parts and production year better than the series name alone.
Indicators and alerts
Dacor cooktop alerts & indicators
For any message not shown, use the manual for the exact model rather than a generic list.
Message / alert
d0 on an induction top
What it means
A key has been pressed for more than 8 seconds - usually a wet or obstructed keypad, per Dacor's own manual.
Safe check
Dry the control area and check for objects; restart with POWER. A returning d0 with a clean panel is a touch-electronics visit.
Message / alert
UP on the display
What it means
Input voltage out of range - the manual points at the power connection, not the cooktop.
Safe check
An electrician verifies the 208-240V supply; this is an installation fault, not a component.
Dacor diagnostics
Dacor cooktop error codes, decoded.
The induction table (C0-C2, F0-F2, A2, UP, d0) comes straight from Dacor's official user manual for the DTI30M/36M977 platform. Gas cooktops have no codes, and that is stated plainly.
Error code · C0 / C1 / C2
Top and IGBT sensors
What it commonly means
Official Dacor table: C0 top sensor open, C1 top sensor short, C2 IGBT sensor open.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Restart per the manual first; persisting C-codes move to sensor and power-module diagnosis.
Error code · F0 / F1 / F2
Board communications
What it commonly means
Official table: F0 main-to-sub PCB link, F1 EEPROM, F2 touch-IC communications failed.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Power-cycle 30 seconds per Dacor's procedure; recurring F-codes are board-level service.
Error code · A2
Cooling fan malfunction
What it commonly means
The DC fan motor cannot run - PCB, wiring or a blocked blade, per the official manual.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
The fan circuit is tested and the blockage or component corrected - ignoring A2 invites overheating.
Error code · UP
Input voltage too high or low
What it commonly means
The supply is outside 208-240V.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
The electrical connection is corrected to spec - a hookup fault, not a parts fault.
Error code · d0
Key pressed over 8 seconds
What it commonly means
A stuck or wet key, officially documented.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Clean and dry first; persistent d0 moves to keypad diagnosis.
Reality check · No codes (gas tops)
Mechanical platforms
What it commonly means
DTG, DTT and legacy gas tops publish no fault codes - igniters, valves and switches are tested directly.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Spark modules, electrodes and burner condition diagnosed by instrument, not by table.
Any other code or behavior
Meanings vary by series and year
Why we do not guess
Dacor products span several control generations; the same characters can mean different things on different series. The complete model number fixes the definition.
What to capture
Photograph the full display and the model label, and note what the appliance is doing.

Helpful answers
Dacor cooktop service questions
Clear preparation makes a service request easier to evaluate.
Do you offer same-day Dacor cooktop repair in Chula Vista?
Yes - same-day windows are offered across San Diego County subject to the day's schedule. Availability is confirmed for the exact address when you book.
Do you service my street in Chula Vista?
We take requests across Chula Vista (ZIP 91910, 91911, 91913-91915). Share gate codes, parking or building access when booking so the technician can plan the visit.
Does the $99 residential diagnostic fee always apply?
Yes. It is non-refundable and credited toward the total repair cost if you proceed. There are no residential exceptions.
What warranty comes with a repair?
A 90-day labor warranty and a 1-year parts warranty, both starting on the date the repair is completed.
Can a symptom alone identify the failed part on a Dacor cooktop?
No. A symptom narrows the search, but the diagnostic visit on the exact model confirms the actual fault before any repair is authorized.
What does F1 mean on my Dacor induction cooktop?
Officially: EEPROM communications failed on the control board. Power-cycle for 30 seconds per the manual; a returning F1 is a board-level service visit.
My cooktop shows d0 - is it broken?
Usually not. d0 means a key has been pressed for over 8 seconds - typically a wet or obstructed keypad. Clean and dry the control area; persistent d0 means keypad diagnosis.
Do Dacor gas cooktops have error codes?
No - they are mechanical with electric ignition. Diagnosis is direct: spark modules, electrodes, valves and burner caps.
Where is the model number?
On the underside of the cooktop, reached from the cabinet below - or on the duplicate label in the installation paperwork.
Do you service the older Distinctive and Renaissance tops?
Yes - legacy Dacor gas platforms remain serviceable; the full model number from the plate decides the parts book.
