What we fix in Minneapolis

The Minneapolis repair mix

F-9 — oven not heating to setpoint

Electric: bake element open ($245–$365) or relay on the main board failed. Gas: igniter weak (resistance climbs as the igniter ages and it stops opening the gas valve) — replace the igniter, $285–$425. F-9 with sealed-burner cooktop working fine = oven-circuit only, not a supply issue.

F-3 / F-4 — oven temp sensor

F-3 = sensor short; F-4 = sensor open. RTD probe at the back of the oven cavity. Cheap swap, $245–$345 all-in.

Field-service notes on oven repair

On oven repair, we keep the diagnostic tight because the failure catalog on this brand is well-documented. The Twin Cities humidity swing — dry January to sticky July — cycles refrigerator door gaskets hard; a gasket that seals in March can pull ambient air by August and drive up compressor run time 15–20%.

Because this page focuses on f-9 — oven not heating to setpoint, our tech opens the call by isolating that subsystem before touching anything else. Wear parts (belts, pumps, igniters, valves) ship from our truck stock; boards and sealed-system parts are OEM-only from Marcone or the manufacturer's direct distributor. The $149 residential diagnostic is credited toward the repair if you approve; if you don't, you pay only the diagnostic and we leave a written scope. Every completed repair carries a 1-year parts and labor warranty in writing. The section above covers the specific failure surface — electric: bake element open ($245–$365) or relay on the main board failed.

We stock the top-30 wear items for this brand on the truck, so most first-visit repairs close same-day. We're EPA 608 certified for sealed-system and refrigerant work, licensed and insured in Minnesota, and every tech carries a factory diagnostic laptop for brand-specific service modes. If the model is out of parts support, we'll say so on the first call and refund the diagnostic — that's the honest read on a repair-vs-replace decision, and it's the same read we'd give a family member calling about the same oven.

FAQ

Minneapolis questions, answered

  • What does F-9 mean on an LG oven?

    F-3 = oven temp sensor short. F-4 = sensor open. Cheap swap of the RTD probe at the back of the oven cavity, $245–$345. The control board logs this code so technicians can skip generic troubleshooting. We carry the OEM service manuals on tablet for every major platform — no guess-and-replace.

  • What does F-7 mean on an LG range?

    F-7 = keypad shorted or button stuck. Try a 5-minute unplug; if F-7 returns, the touch panel needs replacement, $325–$525.
