LO reads differently by product: the beverage center page explains a low temperature, the other two give just a power reset.
Model compatibility: JennAir reuses codes across series and model years, so LO may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
On the beverage center LO means the internal temperature is too low; for the wine cellar and undercounter refrigerator JennAir states no cause.
The meaning of LO depends on which JennAir product is displaying it. Three help pages carry the code.
On a beverage center
The page is titled “CL or LO” and says the code means the internal temperature is too low. It suggests ruling out three situations:
the door is not fully closed or was held open;
the cabinet was recently restocked, since a large load of warm or room-temperature items can lower the temperature;
a power outage occurred lately and the unit needs time to stabilize.
On a wine cellar or undercounter refrigerator
For these two products LO is printed on a shared “HI or LO” page. Neither word is explained there. The page gives the reset described next and no cause at all.
Reset used by all three pages
Switch off power for one minute, either at the breaker or by unplugging.
Turn power back on.
For the next minute, see whether LO comes back.
Confirm that the refrigerator is operating.
When LO stays on
Because the three pages stop after the reset, a lasting LO is something to hand to a technician and not something to hunt for at home.
Why the product matters
Beverage center owners can rule out door, restocking and outage before resetting. Owners of the wine cellar or undercounter refrigerator have only the reset from JennAir. The beverage center explanation should not be applied to the other two, because their pages do not make that claim.
