Dacor Wall Oven Repair in Toronto — Oven not heating at all

• No heat in bake but the display lights and the timer counts: the most common Dacor no-heat cause is an open-circuit bake element. The 30-inch oven bake element is Dacor 62637 (also AP3393456 / PS4264897 / 876995-00); we meter it for continuity at the terminals before condemning anything else, since a dead element looks identical on the panel to a sensor or board fault.
• No heat under broil while bake still works (or vice-versa) isolates the failed circuit to one element: the 3000W broil element is Dacor 82817, superseded on the Samsung platform to DE81-06974A. A burned/open broil loop is replaced as a unit; if both modes are dead, the fault moves upstream to the relay board, not the element.
• Oven runs cold or never reaches setpoint with an F3 (shorted RTD) or F4 (open RTD): the oven temperature sensor reads roughly 1080 ohms at room temperature (70F, +/-10%), and a drifted/open RTD makes the control cut heat. The sensor is DE81-07677A (replaces 62593). We always rule out the sensor harness and its plug at the control before ordering - a loose connector throws the same F3/F4 and the same no-heat behavior.
• Classic Dacor no-heat after a self-clean cycle: the pyrolytic cycle drives the cavity to ~800F and trips Dacor's resettable thermal fuse, killing power to the elements. There is a RED reset button behind the oven's electronics cover/grille that clicks back in; we check/reset that fuse path first on any 'died right after self-clean' Renaissance/Heritage unit before quoting parts.
• Dead heat to the elements with a U43 (upper oven) or L43 (lower oven) relay-board message points to the wall-oven service relay board (DE81-09742A, = legacy Dacor 101559-C), which switches power to the bake/broil circuits. This is a distinct component from the ERC - element continuity, the S19 connection, and the relay board are all verified before the four-figure control board is ever named.
• Persistent F1 (system watchdog circuit) or a safety-critical F2 (heating-mode high-temp / runaway-overheat lockout) on the main oven control board / ERC 62692 (AP3390975): an F1 watchdog fault is cleared with Cancel, and if it persists the control board is condemned, while an F2 runaway-overheat is treated as a fire risk and never reset-and-returned. We confirm the RTD is in-spec and inspect the ERC-to-relay-board connection for shorts/cracked solder before condemning the board.

Dacor oven not heating at all in Toronto — the local specifics

• The recurring Dacor no-heat pattern we see across Toronto is the post-self-clean failure: a homeowner runs the pyrolytic cycle before a holiday or dinner party, the ~800F heat trips the resettable thermal fuse (or stresses an aging element), and the oven powers up normally but never warms. The second recurring thread is a cold-baking unit throwing F3/F4 - a drifted RTD read at the control - that we confirm on a meter rather than parts-cannon the board.
• We roll to Dacor no-heat calls carrying the fast-moving wear parts - bake element 62637 (AP3393456 / PS4264897), 3000W broil element 82817 / DE81-06974A, and the RTD oven sensor DE81-07677A (repl. 62593) - plus a meter to verify the resettable thermal-fuse reset path and element continuity on site. Boards (ERC 62692, relay board DE81-09742A / 101559-C) are confirmed by model/serial and ordered through the authorized channel, never guessed.
