Why This Matters in Calgary
Between Chinook-driven voltage dips, hard water, and renovation dust, LG fridges around YYC trigger fault codes far more often than the owner’s manual admits. The table below covers the 10 most-Googled LG errors in Alberta, what they mean, and the exact moves local techs use to silence them—without losing a freezer full of bison steaks.
| Rank | Code | What It Means | 2-Minute Triage | Likely Part | DIY?* |
|---|---|---|---|---|---|
| ① | 1E / IE | Freezer temp-sensor fault | Unplug 5 min → panel reset | Thermistor EBD60925804 | ★★☆☆☆ |
| ② | CF | Condenser-fan feedback lost | Reseat rear 3-pin plug | Fan EAU65058502 | ★★☆☆☆ |
| ③ | FF | Freezer evap-fan stall | Melt frost behind cover | Fan EAU60783803 | ★★☆☆☆ |
| ④ | IF | Ice-maker fan stalled | Clear ice in ice box | Fan EAU61383505 | ★★☆☆☆ |
| ⑤ | dH / F dH | Defrost heater timed out | Force-defrost test | Heater MEE62305105 | ★★★☆☆ |
| ⑥ | HS | Humidity-sensor fault | Unplug 5 min; ohm-check sensor | Humid-sensor 6500JB2001B | ★★☆☆☆ |
| ⑦ | OF F / O F | Demo mode ON | Press Fridge + Ice 5 s | — | ★☆☆☆☆ |
| ⑧ | PF | Recent power failure | Hold Freezer 3 s | — | ★☆☆☆☆ |
| ⑨ | gF | Low water-flow to ice maker | Reseat filter / flush line | Valve AJU72992601 | ★★☆☆☆ |
| ⑩ | CO / C 0 | Main-board / display comm loss | Unplug 5 min → panel reset | PCB EBR78940615 | ★★★★☆ |

Deep-Dive Fixes & Entity-Rich How-Tos
Below, each error gets its own mini playbook. Every “Quick-Fix” clears 70-90 % of service-call cases in Calgary; the “Pro-Level” steps cover the head-scratchers.
1. 1E / IE – Freezer-Sensor Failure
Entities: thermistor, evaporator wall, voltage surge, Chinook, DA32-style NTC sensor.
Quick-Fix (≤ 10 min)
Unplug fridge 5 minutes (LG caps bleed slowly).
Plug in, press Energy Saver + Lighting 10 s → self-test.
If code clears—done.
Pro-Level
Freezer bins out → 6 Phillips screws → lift rear cover.
Ohm sensor @ 25 °C: 4.7 kΩ ±10 %. Outliers = swap EBD60925804.
Call a Tech When: 1E returns twice in 48 h or freezer won’t reach –18 °C.
2. CF – Condenser-Fan Feedback Fault
Entities: Hall-sensor pulses, PCB feedback circuit, fan motor EAU65058502.
Quick-Fix
Unplug → remove rear service plate.
Vacuum lint; reseat white 3-pin harness.
Plug in; fan should spin within 30 s.
Pro-Level
Coil test: 125–200 Ω @ 25 °C. ∞ Ω or < 50 Ω = new fan.
3. FF – Freezer Evaporator-Fan Error
Entities: frost blanket, iced blades, evaporator cover, defrost pattern.
Quick-Fix
Hard-reset 5 min.
Freezer drawers out → rear cover off.
Hair dryer LOW, 15 cm away, sweep till blades spin freely.
Tip: If frost returns weekly, check drain heater.
4. IF – Ice-Maker Fan Error
Entities: ice-box, fill-tube heater, Hall sensor, EAU61383505.
Quick-Fix
Turn Ice Plus OFF to idle fan.
Remove ice bucket; melt frost around fan grille with warm air.
Press Freezer + Ice Plus 10 s to self-test.
5. dH / F dH – Defrost Heater Timeout
Entities: defrost cycle, thermistor, heater relay, time-out counter.
Quick-Fix
Hold Fridge + Freezer 8 s → tap Freezer until “Fd” (Forced-Defrost).
Close doors 20 min; code often clears.
Pro-Level
Heater continuity: 20–40 Ω. Open = swap heater MEE62305105.
6. HS – Humidity-Sensor Fault
Entities: crisper humidity, analog-to-digital converter, sensor harness.
Quick-Fix
Unplug 5 min.
Reseat tiny 3-wire plug in veggie drawer roof.
If HS persists, ohm-test: 30–50 kΩ @ 25 °C.
7. OF F / O F – Demo (Display) Mode
Entities: showroom mode, compressor lockout, disengage demo.
Instant-Fix
Press Fridge + Ice 5 s (newer models) or Freezer + Ice Plus 5 s (older).
Audible beep; temps return.
8. PF – Power Failure Memory
Entities: brown-out, surge, voltage log.
Fix
Hold Freezer 3 s to clear.
Add a 1 000 J surge bar to prevent repeat PF / CF combo.
9. gF – Water-Flow Error
Entities: flow sensor, frozen fill-tube, clogged filter, AJU72992601 valve.
Quick-Fix
Replace filter (ensure genuine).
Reseat 3-pin flow-sensor harness behind hinge.
Flush 2 L water; reset by holding Filter 3 s.
10. CO / C 0 – Board Communication Loss
Entities: I²C bus, display PCB, main PCB, ribbon cable.
Quick-Fix
Unplug 5 min.
Reseat door-hinge ribbon and display PCB connectors.
If CO re-flashes, main PCB EBR78940615 may be weak.

When to Book a YYC Tech
Same code fires twice in 48 h.
Coil readings out of spec.
Burnt smell, scorched board, or melted harness.
Freezer temp rises above –5 °C for > 4 h.
LG-certified vans cover NW • NE • SW • SE with most fans and sensors onboard.
Zero-Error Protocol—Keep Codes Away
Surge bar ≥ 1 000 J on the fridge circuit.
5-min rule after any outage before re-powering.
Quarterly coil vacuum + drain flush (100 ml hot water).
Door-seal “dollar-bill” test each season.
Rear-vent gap 5–8 cm; no pizza boxes rammed in back.
Lightning-Round FAQ
Will a 5-min hard-reset wipe Wi-Fi?
Yes—re-pair in LG ThinQ.
Oil the fan bearings?
No—sealed; oil attracts dust.
Can 20 min of door-open work spoil meat?
Temp rise ≈ 2 °C. You’re safe.
Insurance for spoilage?
Most Calgary policies cover ≥ $500; keep code photos + receipts.
Top LG fridge errors (1E, CF, FF, IF, dH, HS, OF F, PF, gF, CO) stem from sensor ice, dust-jammed fans, demo mode, or brown-outs. Unplug 5 min, clear frost, reseat harnesses, replace weak parts, and fit a surge bar to stop repeat alarms.
