Answer to continue safely
Is it safe to keep using?
No. The rangetop cannot be used while the control lockout is active. Resolve the lockout condition before attempting to cook.
Can I reset the code?
Yes. The control lockout is reset by performing the deactivation button sequence per the user manual. A breaker power cycle may also clear the state if the panel sequence does not respond.
When to stop immediately?
Stop if you notice: Stop attempting the deactivation sequence after 5 tries — repeated incorrect entries may extend the lockout period on some models., Do not use the rangetop if knobs feel mechanically stuck as well as electrically disabled — this is a different fault..
Symptoms You May Notice
Knobs turn but burners do not ignite or allow gas flow
Turning any burner knob produces no click and no gas flow, even though the knob rotates normally. The electronic control has disabled the ignition circuit and, on models with electronic gas valves, the gas path.
Lock indicator light is illuminated on the control panel
A small lock or key icon on the rangetop's electronic control panel is lit, indicating the child lock feature has been activated — either intentionally or accidentally.
All burners are affected simultaneously
Unlike a mechanical or single-burner fault, the control lockout disables all burner controls at once. No burner will ignite while the lock is active.
Control panel buttons are unresponsive
Touch or button controls on the electronic panel do not respond to single presses. The lockout is typically designed to require a specific button sequence or hold to prevent accidental deactivation.
Possible Causes
Child lock intentionally or accidentally activated
The lockout feature was enabled through the control panel — either deliberately for safety or accidentally by leaning against the control area during cleaning.
DIY PossibleControl panel button stuck or shorted after cleaning
Moisture from surface cleaning can temporarily short a panel button, triggering the lockout sequence without user intent. The panel should dry fully before the issue resolves.
DIY PossibleControl board fault holding the lockout state
In rare cases, the electronic control board retains a lockout state through a power cycle, suggesting a fault in the board's EEPROM or control logic.
Requires ProfessionalSafe Checks You Can Do
-
1
Deactivate the control lock per the user manual
Locate the lock deactivation sequence in the Dacor HRTP user manual. Typically this involves pressing and holding a specific button (often labeled "Lock" or with a key icon) for 3–5 seconds. The lock indicator should extinguish and normal operation resume.
The Dacor HRTP manual is available on the Dacor support website under the rangetop's model number documentation.

2
Perform a power cycle if lock will not deactivate
Turn off the rangetop at the circuit breaker, wait 30 seconds, then restore power. Attempt the lock deactivation sequence again. A power cycle clears transient control board states that may be holding the lockout.
Some HRTP models require the deactivation sequence to be performed within 10 seconds of restoring power from a breaker reset.

3
Dry the control panel if recently cleaned
If the lockout appeared immediately after cleaning the rangetop surface, moisture may have shorted the panel. Allow the panel area to dry completely — ideally 2–4 hours — then attempt the deactivation sequence again.
Use only a damp cloth on the control panel — never spray cleaning products directly at the controls.
When to Call a Professional
Contact a qualified technician if:
- Control lock cannot be deactivated after power cycle and correct button sequence — control board EEPROM fault suspected.
- Lock indicator flickers or behaves erratically — panel button or control board issue requires inspection.
- Lock activates spontaneously during cooking — intermittent panel fault requires technician diagnosis.
