Dacor Stove Repair in Toronto — Induction element not working / fault code

• One induction zone goes stone-cold while the others still cook: on Dacor's Samsung-era induction platform (DTI30/DTI36 Modernist/Contemporary LCD cooktops, built on the Samsung NZ30/NZ36K7880 architecture) each zone or zone-pair is driven by its own inverter PCB, so a single dead zone is most often a failed inverter board for that position rather than the whole cooktop. The right-side inverter is Samsung/Dacor DG92-01036A (AP6245007) and the left-side is DG92-01035A ('PCB INV-LT'). We confirm the rest of the surface still heats and the touch panel commands the dead zone, then meter that side's inverter before condemning a board instead of parts-cannoning the whole set.
• A 'bo' error (IGBT sensor open) is the induction-specific tell that the zone's inverter has lost its power-switching device: the IGBT is the high-voltage transistor that chops DC into the high-frequency field that heats the pan, and when its sense circuit reads open the control kills that zone so it never energizes. Per Samsung/Dacor service literature 'bo' points at the inverter PCB (DG92-01036A right / DG92-01035A left), its IGBT, or the wiring harness from the top sensor to the inverter. We meter the inverter and its harness before ordering, because a loose top-sensor-to-inverter plug throws the same code without the board actually being bad.
• Whole panel reads a 'd0' (or 'SE') touch-button error and no zone will start: that is a shorted or stuck capacitive touch sensor on the LCD/touch PCB, not an induction-coil fault. The most common cause on these glass-top Dacor units is liquid bridging the touch area or a failed harness between the touch PCB and the inverter board. We power the cooktop down for a full minute and wipe/dry the touchpad first; if d0 returns after the reset and the touch-to-inverter ribbon checks out, the touch/control PCB is condemned, not a coil or inverter.
• A 'C1' / 'ot' over-temperature fault (surface above ~250C) or a 'C0' top-sensor error cuts a zone before it ever gets hot: each zone has a coil thermistor (top sensor) bonded under the glass that the inverter watches, and a drifted, shorted, or open sensor makes the control shut that zone down as a runaway-protection measure, so the element 'won't work' even though the inverter and coil are fine. We read the coil sensor and check its plug at the inverter PCB before condemning any power board — an inexpensive sensor or a reseated connector can clear a no-heat zone that otherwise looks like a power-board failure.
• An 'A2' or 'FL' inverter-fan error takes zones offline as a self-protection: the cooling fan that pulls heat off the IGBT/inverter stack has stalled or failed, so the control throttles or shuts the affected zones to keep the power electronics from cooking themselves. The fix here is the blocked/failed inverter cooling fan and clearing the airflow path, not the coil — we verify fan rotation and the vent path under the unit before naming any inverter or coil part, because installing an inverter into a unit that overheats it will just kill the new board.
• A communication fault between the inverter and touch boards on a standalone cooktop shows as 'CE' (communication error between the display/touch PCB and the inverter PCB) and leaves zones unresponsive with the panel still lit: the touch PCB issues the heat command but the inverter never receives or acknowledges it, so the zone never fires. We check the inter-PCB harness and connectors first, then isolate whether the touch PCB or the inverter PCB (DG92-01036A / DG92-01035A) dropped the link before condemning either order-only board. (The Samsung E-5x/E-8x communication codes belong to the induction-RANGE platform, which has a separate oven control PCB and power-relay PCB, so they do not apply to these standalone DTI cooktops.)
• A zone that 'won't work' but throws no error code, or flashes the pan-detection symbol (underlined-u / 'Ou'), is usually a cookware or detection issue, not a failed element: induction needs ferrous, magnetic-bottom cookware sized to the zone, and the auto-shutoff drops a zone that sees no pan, an empty/dry pan, or a non-magnetic base. We test the dead zone with a known-good magnetic pan and confirm the pan-detect coil reads before opening the unit, so a 'no-heat zone' that is really a cookware problem clears with zero parts.

Dacor induction element not working / fault code in Toronto — the local specifics

• On Toronto Dacor DTI induction cooktops with a dead zone, our method is to separate a true single-side inverter PCB failure (one zone-pair out, others fine) from a coil top-sensor / C1-C0 sensor fault that masquerades as a board failure, and from a cookware/pan-detection issue — we rule out non-magnetic or wrong-size cookware and read the coil sensor on site before condemning any costly inverter board.
• We bring coil top-sensors, inter-PCB harness/connectors, and a known-good magnetic test pan to these calls, plus a meter to confirm the IGBT/'bo' inverter fault by side before ordering the serial-matched DG92-01036A (right) or DG92-01035A (left) inverter PCB through the authorized channel. The four-figure LCD/touch control boards for the DTI Modernist/Contemporary series are confirmed by model/serial and ordered, never carried; any all-zone/control board is verified against the serial first, since Samsung's range-platform surface-element board does not fit these standalone cooktops.
