LG Dryer Repair in Toronto — Tripping the breaker / blowing a fuse

• Grounded heating element is one of the most common documented LG tripping-breaker causes (DLE/DLEX line): the breaker trips the instant a heated cycle starts, or within seconds, while a tumble-only/air-fluff cycle runs all day without tripping -- the classic signature that the fault is in the 240V heat circuit, not the motor. The element is the LG 5301EL1001J heating element assembly (240V/5400W, supersedes 5301EL1001E/G/H), and when the nichrome coil sags and touches its own metal housing it shorts to ground and dumps fault current straight to chassis. We confirm it the way RepairClinic documents: meter terminal-to-terminal for the element's normal resistance (roughly 7-20 ohms; an open coil reads infinity = a no-heat fault, not a trip), then meter EACH terminal to the bare housing -- ANY continuity to ground there is the grounded element, and the 5301EL1001J swap renews the element, integral high-limit (6931EL3001F) and thermal fuse (6931EL3003D) together.
• We isolate heat-circuit trips from motor/control trips before condemning a single part, because the cure is different. The field test (per the LG tripping-breaker references) is to disconnect the heating-element leads, reset the breaker and run a tumble-only cycle: if the breaker now HOLDS, the short was in the element/heat stack (the grounded 5301EL1001J); if it STILL trips with the element disconnected, the fault is upstream in the drive motor or wiring. This one step stops us from selling an element to a customer whose real fault is a grounded motor, and vice-versa.
• Shorted drive motor is the LG trip that survives the element-disconnect test -- the breaker still pops with the heater unplugged. The part is the LG 4681EL1008A drum drive motor (120V, 60Hz, 6.2A, 1/3HP, 1725 RPM; supersedes 4681EL1002A/B, 4681EL1006A/F, current LG supersession EAU30126201). When the windings break down and short to the motor housing it grounds out on start, so the load-bearing test is to meter winding-to-winding AND winding-to-frame: ANY continuity to the frame condemns the 4681EL1008A. AppliancePartsPros publishes a centrifugal-switch resistance check for this motor as a secondary confirmation -- roughly 2-3 ohms terminal 4-to-5 with the switch at rest and 3-5 ohms engaged -- but the grounded-winding-to-frame reading is what proves the trip. We always rule out a bound idler/roller first, because a dragging drive train overloads the SAME motor and can nuisance-trip a tired breaker without the windings actually being shorted.
• Scorched terminal block or burnt power-cord connection is a tripping-breaker cause LG warns about directly -- on its own 'burning or discolouration' support page LG flags loose/heated connections at the back terminal block. A screw that vibrated loose over years arcs, cooks the insulation, and the bare/melted lug eventually faults to the cabinet or restricts current until the breaker overheats and trips. We pull the small rear cover, inspect the terminal block and the 240V cord lugs for browning/melt, and either re-land clean copper or replace the cord/block -- never bridge or tape it. This is also the fault behind a trip that comes with a faint burnt-plastic smell rather than the clean instant trip of a grounded element.
• Burnt heater/sensor harness connectors throw a trip the same way the terminal block does, one node deeper in. On a chronically restricted (vent-blocked) LG the spade connectors at the heater, high-limit (6931EL3001D) and thermal fuse (6931EL3003D) run hot, the insulation chars, and a bared wire arcs to the heater housing -- a ground path that trips the breaker and is easy to misread as a dead element. We inspect every heater and safety-device spade for heat-discoloration and scorch, cut back to clean copper and splice in a fresh connector, AND clear the vent run that overheated it, or the next connector chars and we're back. (A blown 6931EL3003D from that same overheat is a no-heat fault, not a trip -- we keep the two stories separate.)
• Gas-model trips (DLG) sit in the burner's low-voltage circuit, not the 240V heat stack -- there is no electric element to ground out. If a DLG trips its breaker or blows the in-line fuse on a heat call we look at the 5318EL3001A burner igniter circuit and the gas valve solenoid coils (LG sells these only as the complete gas valve assembly AGM30063309 -- the coils are not broken out separately): a shorted igniter or a coil that has broken down can ground the burner harness. We watch one full ignition attempt at the inspection window and meter the igniter/coil circuit to ground before quoting, because the gas-model trip is a different animal from the electric grounded-element call and the electric heat parts (5301EL1001J) do not apply.
• PS / reversed-cord wiring is the LG-coded trip that is really an install error, not a failed part. Per LG's official code list, PS flags improper voltage in the power cord, which LG attributes to the white (neutral) and red (hot) wires being reversed at the terminal block -- classically right after a move or a new cord install. A mis-landed neutral/hot can put the machine in a fault state and, on the wrong panel, trip the breaker. We meter both legs and the neutral at the terminal block and verify the cord landing against LG's diagram before opening any panel, because no element, motor or board will fix a cord wired backwards.

LG tripping the breaker / blowing a fuse in Toronto — the local specifics

• A pattern we commonly see across Toronto is the grounded 5301EL1001J heating element on DLE/DLEX machines -- the customer reports the dryer runs fine on air-fluff but trips the breaker the second the heat kicks in, and the element-disconnect isolation test repeatedly lands it on a coil-to-housing ground rather than on the motor. The recurring twist on this specific call is how often it turns out NOT to be the machine at all: in older Toronto homes and reno'd condo laundry closets, the trip traces to a left-in neutral-ground bonding strap on a 4-wire changeover or to a GFCI/AFCI breaker, so we run the wiring/bond check before selling any heat part.
• We roll to a Toronto LG trip-call with the grounded-element stack (5301EL1001J heating-element assembly with its integral 6931EL3001F high-limit and 6931EL3003D thermal fuse, plus a standalone 6931EL3001D high-limit / 6931EL3003D thermal fuse), the 4681EL1008A drive motor for the element-disconnect-still-trips case, and a 240V power cord / terminal-block repair kit for burnt-lug trips. For DLG gas calls we add the 5318EL3001A igniter and AGM30063309 gas valve; for DLHC heat-pump compacts we confirm the model-coded board/compressor by serial before the visit.
