What LL
actually means.

Marvel shows LL when the freezer stays below its control setting for an extended time. The freezer is still keeping food frozen, but a control that overshoots this way can point to a sensor or control problem.

What to do when LL shows on the freezer

Kind of codeTemperature and alarms

The freezer measured a cabinet warmer than it should be and said so, sometimes with the highest temperature it reached while nobody was looking. The cause can be as simple as a door left ajar or a long power outage, or as serious as a compressor that stopped. Keep the door or the lid shut and check whether the food is still hard before anything else; the alarm is a warning about the food, not a diagnosis.

Usually leads toFreezer thermostat and temperature control repair

Repairing the dial thermostat or the sensor and control that decide when a freezer cools, so it stops running without end or quitting too early.

Shows up asFreezer Error Code

A freezer error code appears on the display: letters and digits, a flashing temperature, or a warning symbol, sometimes with an alarm and sometimes with the freezer still running.

Before you book,
in this order.

Each step comes from Marvel's own guidance for LL on its freezers. Follow it to the end: the last card says whether this is a visit.

01

Check the setting first; Marvel freezers accept settings from −10°F to 10°F.

02

Measure with a thermometer between packages to confirm how cold the cabinet really is.

03

If LL keeps coming back at a normal setting, book a visit so the sensor and control can be checked.

Still there?

It usually turns into freezer thermostat and temperature control repair. Book with the code and the model number.

What not to do

LL is not a food safety emergency; the food stays frozen. It is also not the high temperature notice, which Marvel shows as HH.

Questions
about LL.

Can I clear LL myself?
Check the setting first; Marvel freezers accept settings from −10°F to 10°F. If it comes back, it needs a visit.
Can a Marvel freezer be too cold for food?
Frozen food is not harmed by extra cold, but the freezer is using more energy than it needs. LL mainly tells you the control is not holding your setting.
Why would my Marvel show LL in a cold garage?
A very cold room can drag the cabinet below the setting, since the freezer cannot heat itself. Check the room temperature before booking a repair.
What part usually causes LL on a Marvel?
The compartment sensor or the control are the usual suspects when the setting is normal. A technician reads the error log in service mode to narrow it down.

Back to your everyday

Still showing LL?

Book with the code or the alarm pattern written exactly as the freezer shows it, the full model number, and whether the food is still frozen hard — when there is a code, that is where the diagnosis starts.
