JennAir Undercounter Wine Cellar Over Temp: Zone Above Preset for 10 Minutes

What Over Temp means

On JennAir undercounter wine cellars such as the JUWFR and JUWFL series, Over Temp is an audible and visual alert. It sounds when the temperature in either zone rises above its preset range for 10 minutes. The sound stops on its own when the temperature returns to normal, but the indicator light keeps flashing until the Reset Alarm touchpad is pressed, so you know it happened.

Common causes of Over Temp

The door was left open or is not sealing
A large load of warm bottles went in at once
Poor airflow around the cellar, with the vents blocked
A cooling or sensor problem if the temperature never returns to normal

✓ One safe check you can try

1. Check that the door is fully closed and the gasket lies flat. 2. Make sure nothing blocks the front vents or the space around the cellar. 3. Give the zone time to come back into range, and the sound will stop on its own. 4. Press the Reset Alarm touchpad to clear the flashing indicator once the temperature is normal.

! Why to stop there

A door or loading cause clears itself, so a visit would cost money without changing anything.
Wine is damaged by warm spells, so you should know quickly if the cooling itself has an issue.
If the alert keeps returning on a closed, unobstructed cellar, we check the cooling system and quote the price in writing.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Over TempOver Temp questions

The alarm stopped. Why is the light still flashing?

The sound stops automatically when the temperature returns to normal, but the indicator light keeps flashing until you press the Reset Alarm touchpad. It is there so you know it occurred.

How long must the temperature be high before the alert?

The zone has to sit above its preset range for 10 minutes. A short door opening will usually not trigger it, but a longer one or a big warm load can.

When is Over Temp a real problem?

When it returns on a closed door with clear vents and the temperature stays high. Then the cooling needs a proper check. Call us and we quote the price before any work.
