LG Fridge Not Cooling in Ottawa? Here’s What’s Wrong and How to Fix It

LG refrigerators are one of the most popular fridge brands in Ottawa and across Canada — known for their French-door designs, smart features, and sleek aesthetics. But LG fridges do have some well-documented failure points that Ottawa homeowners should know about. This guide walks through the most common reasons an LG fridge stops cooling and what you can do about it. B&M Canada Appliances provides expert LG fridge repair across Ottawa and Gatineau — call (613) 301-0016.

Most Common Reasons Your LG Fridge Isn’t Cooling

1. LG Linear Compressor Failure

This is the most discussed LG refrigerator problem in Canada, and for good reason. LG introduced their Linear Compressor technology as a more efficient and quieter alternative to traditional reciprocating compressors. While the technology is genuinely more energy-efficient when working correctly, it has a failure rate that has led to class-action lawsuits in the United States. Symptoms of a failing LG linear compressor include: the fridge and freezer both gradually warming up, a clicking or knocking sound from the bottom/back of the unit before it stops cooling, and the compressor running very briefly then shutting off. LG extended the warranty on linear compressors in some models to 7 years or 10 years depending on the year of manufacture. Check your model number at LG.ca to confirm warranty coverage. Our certified technicians can diagnose and replace LG linear compressors with OEM LG parts.

2. LG Evaporator Fan Motor Failure

If your LG fridge is warm but the freezer is still cold, the evaporator fan motor is a prime suspect. The evaporator fan circulates cold air from the freezer section into the refrigerator compartment. When it fails, the freezer stays cold while the fridge warms up. You may hear the fan running intermittently or making grinding/squeaking noises before it stops entirely. LG evaporator fan motors for French-door models are model-specific but readily available as OEM parts. This is a same-day repair in most cases.

3. LG Defrost System Failure

LG refrigerators use an automatic defrost cycle to prevent ice buildup on the evaporator coils. When the defrost heater assembly, defrost thermostat, or defrost control fails, ice builds up over the evaporator coils and blocks all airflow into the fridge compartment. You’ll often see or hear ice buildup in the freezer section, and the fridge temperature will gradually climb while the freezer stays cold. This is a very common LG repair that we perform regularly across Ottawa. A manual defrost (unplugging the fridge for 24–48 hours with towels to catch water) temporarily restores cooling — but the underlying component must be replaced to prevent recurrence.

4. LG Smart Inverter Compressor Issues

Newer LG models use a Smart Inverter compressor rather than the original Linear Compressor. These are generally more reliable, but they can still fail — particularly the inverter control board that manages compressor speed. When the inverter board fails, the compressor may not receive proper signals to run, resulting in a fridge that’s completely warm. Diagnosing inverter board vs compressor failures requires specialized tools — this is not a DIY repair.

5. LG Ice Maker Blocking Airflow

LG French-door refrigerators with in-door or upper-compartment ice makers can develop ice buildup around the ice maker assembly that blocks airflow. This is a known issue on several LG French-door models (LRFXS2503S, LFXS26973S, and similar). The ice maker area freezes solid and the ice maker stops making ice while fridge cooling becomes inconsistent. LG has issued technical service bulletins on this issue, and the repair involves a specific defrost procedure and updated parts in some cases.

6. Faulty LG Main Control Board

The main control board (PCB) controls all fridge functions including the compressor, fans, defrost cycle, and temperature sensors. When it fails, you may see error codes on the display (r DH, Er FF, Er CF, Er rF are common LG error codes), or the fridge may behave erratically — cycling on and off, maintaining wrong temperatures, or not cooling at all despite the compressor running.

LG Fridge Error Codes: What They Mean

LG fridges display error codes to help diagnose problems. Here are the most common ones our Ottawa technicians encounter: Er FF means evaporator fan motor failure in the freezer section. Er rF means evaporator fan motor failure in the refrigerator section. Er dH means a defrost heater failure. Er CF means a condenser fan motor failure. r DH (blinking) indicates the fridge has entered a forced defrost mode and may need servicing. FS (flashing) indicates a sensor failure. If you see any error code on your LG refrigerator display, call B&M Canada for a same-day diagnosis.

Is My LG Fridge Under Warranty?

LG Canada offers a 1-year parts and labour warranty on most appliances, with extended compressor warranties on many models. For the Linear Compressor specifically, LG extended the warranty to 7 years (parts and labour) on units manufactured from 2014 onward, and 10 years on the compressor part only in some regions. Visit LG.ca or call LG Canada at 1-888-542-2623 to check your specific model’s warranty status. Note that warranty repairs must be performed by an authorized LG service centre. B&M Canada performs both warranty and out-of-warranty LG repairs.
