LG Stove Repair in Toronto — Electric element not heating

• First the platform split that keeps the quote honest: on an LG electric range a dead surface burner throws NO display code, while an oven that won't reach temperature throws F9 (the control could not get the cavity to 150F within five minutes of preheat). So a cold cooktop zone is a hardware-isolation job (element to switch to surface board), and an F9 is an oven-side path (bake/broil element to RTD to relay board) - we work each on its own track instead of chasing a board for a cold burner that never reports a code.
• Oven won't bake / long weak preheat with or without F9 is most often the bottom bake element, LG MEE62306405 (genuine OEM; replaces AP6837264 / PS12716127 / 4929206). The nichrome inside opens from years of heat cycling, so the oven never reaches temp on bake while broil from the top still works. We confirm with a meter (open circuit / no continuity) and look for a visible blister, dark spot, or break before swapping - an element that won't glow and reads open is condemned, not the control.
• No top heat / won't brown while bake still works is the mirror fault: the LG broil element MEE62306504 (OEM, continuity-tested). When it opens you get no glow and no heat on broil but bake can be fine, because on this platform bake and broil are separately fed. We test the broil element for continuity and inspect for a break/blister rather than assuming the board, since one dead element does not mean a dead relay board.
• Oven heats wrong or not enough and trips F9 even with good elements points at the RTD oven temperature sensor, LG EBG61305805 (genuine OEM; replaces EBG61305801). It should read about 1080-1100 ohms at room temperature; a cracked or open sensor makes the control read a false extreme so it stops calling for heat and posts F9. We meter the sensor to the ~1080-ohm spec at the connector before condemning it - this is the most misdiagnosed electric no-heat behind a plain dead element, and a $90-$150 sensor is far cheaper than a needless relay board.
• F9 with elements and sensor testing good is the oven relay control board, LG EBR74164814 (genuine OEM oven relay board). It takes the call from the main control and switches the relays that feed the bake/broil elements; a burnt relay or scorched board means a good element gets no power and the oven never heats. LG's and the parts distributors' guidance lists the relay board as a common F9 cause - but we condemn it LAST, only after the bake element (MEE62306405), broil element (MEE62306504) and RTD (EBG61305805) check out, so a $30 element job never gets sold as a $300 board.
• One cooktop zone stone cold while the others heat is the radiant surface element at that position, LG MEE64286401 or 5300W1R004A (both OEM radiant elements per RepairClinic). The coil opens like a light bulb and isn't repairable - we meter it for continuity and, if it reads open, swap that single zone. If it has continuity but still won't heat, the fault moves to the switch or surface board, not another element.
• Element reads good but the burner is dead = the surface element (infinite) control switch, LG EBF62174906 (OEM; family EBF62174901/904/907, cross-refs AP6037530 / PS11771631). The infinite switch cycles 240V to set the heat level, so a burnt or open contact leaves a perfectly good element cold at every setting - we meter for voltage out to the element at HIGH before ordering any radiant element. When TWO or more burners go cold together, the suspect shifts upstream to an upstream model-coded control board (EBR77562706-class) that carries the cooktop relays on applicable models - simultaneous-zone failure is a board signature, not two coils dying at once, and we verify the exact board against the customer's model/serial since the part number varies by model.

LG electric element not heating in Toronto — the local specifics

• The recurring LG-in-Toronto pattern for electric-element-not-heating is the F9 won't-bake call where the homeowner already assumes the bake element is dead, but on the bench it's split roughly three ways between an open MEE62306405 bake element, a drifted/open EBG61305805 RTD sensor, and the EBR74164814 relay board - so we always meter all three rather than swapping the obvious element. On the cooktop side the recurring one is a single cold zone that turns out to be the EBF62174906-family infinite switch with a perfectly good radiant element behind it, plus the 'two burners died together' calls that land on the model-coded surface element control board.
• We bring the MEE62306405 bake element, MEE62306504 broil element and EBG61305805 RTD sensor to every LG electric no-heat / F9 call (the three parts that resolve most of them same-visit), plus a multimeter to isolate the EBF62174906 infinite switch and the MEE64286401 / 5300W1R004A radiant elements on a cold cooktop zone. The EBR74164814 relay board and the model-coded surface element control board we confirm by serial and bring on the follow-up only after the cheaper parts test good.
