An LG LRMVS3006 that seems to run all the time is often normal, and LG's manual says so: a new high-efficiency refrigerator runs longer than an older one but uses less energy; after installation or a power cut it can take 24 hours to cool fully; warm rooms, opened doors and hot food make the compressor run more; and at about 70 F room temperature it should run roughly 40 to 80 percent of the time. Doors not fully closed and a clogged condenser cover are the causes worth fixing.
Differential
Likely causes of “LG refrigerator runs constantly or cycles too often”, and how to tell them apart
- 1
A replacement for an older model
What separates it The new refrigerator runs much longer than the old one but the electric bill is lower
How to confirm Compare against LG's note that modern refrigerators run longer with better efficiency
- 2
Doors opened often or hot food added
What separates it The compressor runs after grocery loading or many door openings, then settles
How to confirm Cut openings, group what you need, and let hot food cool before storing
- 3
A door not fully closed
What separates it The gasket does not touch on one side, the door alarm chirps or the fridge feels warm at the door
How to confirm Push doors firmly shut and see the door page if they pop open
- 4
A hot location or a clogged condenser cover
What separates it The back or side is hot and the room is above about 80 F
How to confirm Vacuum the condenser cover and vents; keep the room below 110 F
Before you touch a setting
Record this first — changing settings destroys the evidence
- How long since installation or the last power cut
- Room temperature and how much clearance the refrigerator has
- Whether the doors seal fully and whether the compressor cycles off at all
Try in this order
0 of 5 completedGive a new or restarted fridge a day
ReversibleLG says it takes up to 24 hours to cool completely after installation or power restoration, and a refrigerator replacing an older model will run longer than the old one.
Reduce heat and door openings
ReversibleLG says adding food and opening the door warms the refrigerator so the compressor runs longer. Get what you need at once, keep food organized and close the door quickly.
Check that both doors seal
ReversibleFirmly push the doors shut. If they will not close all the way, use the door page. Clear packages and bins that hold a door ajar.
Clean the condenser cover and vents
ReversibleUse a vacuum with an attachment on the condenser cover and vents. LG says not to remove the panel covering the condenser coil area.
Check the room temperature
ReversibleAt normal room temperature (70 F, 21 C) LG says to expect the compressor to run about 40 to 80 percent of the time, and more in warmer rooms. Do not run it above 110 F (43 C).
Model-specific
What is true of this model and not of its siblings
- Running-time notes from the manual
- About 40 to 80 percent run time at 70 F, more when warmer; up to 24 hours to cool after installation or restoring power; room limit 110 F (43 C); vacuum the condenser cover and vents but leave the coil panel on.

Stop boundary
When this stops being a self-service repair
- !If the compressor never cycles off for days in a normal room with sealed doors and a clean condenser cover, call LG customer service
- !If food is warm as well as the compressor running constantly, see the not-cooling page and call LG after 24 hours
- !If you hear clicking every few seconds with no cooling, unplug and call LG

Exact questions
Common questions
Why does my LG refrigerator run so much?+
LG says a new refrigerator replacing an older one runs longer because modern high-efficiency models need more operating time but use less energy.
How long should the compressor run?+
At normal room temperatures (70 F, 21 C) LG says about 40 to 80 percent of the time, and more in warmer conditions.
Does opening the door matter?+
Yes. LG says opening the door and adding food warms the refrigerator and makes the compressor run longer.
How long does it take to cool after being plugged in?+
Up to 24 hours to cool completely, according to LG.
Can a dirty condenser cause constant running?+
LG lists a clogged condenser or back cover as a cause. Vacuum the cover and vents without removing the coil panel.
What is the maximum room temperature?+
LG says it should not be operated above 110 F (43 C).
Does Smart Grid change running?+
The Smart Refrigerator function can control energy use or delay some functions during peak periods on models with Wi-Fi, and you can override it.
Is a high-pitched sound part of running?+
Yes. LG says the high-efficiency compressor may run longer than an older one and a pulsating or high-pitched sound is normal.
