Everything else about this problem
Is it an emergency?
Is an LG refrigerator that won't start an emergency?
Usually not, but it can be. Because this can be an emergency, leave it off and get it checked; don't reset it or turn it back on. Stop and call a pro if it keeps tripping the breaker or smells like burning.
Symptoms & causes
An LG refrigerator that won't start typically shows no signs of power, such as a blank display, no interior lights, and no compressor hum. This issue often stems from a lack of power reaching the unit, a malfunction in the main control board, or a failure of the compressor's starting components. Tracking down the exact cause requires checking the power outlet, the refrigerator's power cord, and internal electrical components.
Tools & parts
Essential tools for checking an LG refrigerator that won't start include a multimeter for checking voltage and continuity, a basic screwdriver set, and potentially wire strippers. Common replacement parts might include an LG Main Control Board or an LG Start Relay/Capacitor assembly for the compressor. A new LG power cord may be needed if damaged.
Safety first
Always unplug the LG refrigerator from the wall outlet before performing any inspection or repair to prevent electrical shock. If the outlet is inaccessible, turn off the dedicated circuit breaker for the refrigerator at your home's electrical panel. Be mindful of sharp edges on internal components and wear appropriate gloves to avoid cuts during the repair process.
When to call a pro
A professional technician is required if the LG refrigerator's compressor has failed, as this involves specialized tools for refrigerant handling and replacement. Issues with the sealed refrigeration system, such as a refrigerant leak or a clogged line, also necessitate a certified professional due to environmental regulations and complex repair procedures. Furthermore, if extensive tests point to a deep-seated control board malfunction that isn't easily replaceable or requires firmware flashing, a service technician is best equipped to handle it.
Questions people ask
Why is my LG refrigerator completely dead?
It's often due to a power supply issue, such as a tripped circuit breaker or a faulty outlet. Less commonly, the main control board or a critical component like the compressor start relay might have failed.
How can I check if the power outlet is working for my LG fridge?
Plug another small appliance, like a lamp or a phone charger, into the same outlet to see if it powers on. If it doesn't, check your home's circuit breaker panel for a tripped breaker.
What if the LG refrigerator hums but doesn't start cooling?
If you hear a hum but no cooling, the compressor might be struggling to start, often due to a faulty start relay or capacitor. It could also indicate a problem with the compressor itself or a sealed system issue.
