What Lo
actually means.

Lo is the low temperature alarm on the Danfoss control. Randell presets the control but notes that elevation, food type and the kind of kitchen may call for adjustment. A set point pushed too low to fight a warm rail can freeze product in the base.

What to do when Lo shows on the commercial appliance

Kind of codeTemperature and alarms

The controller has seen a temperature outside the band it was set for and is saying so: a box above its alarm point, a fryer vat or an oven cavity that tripped its high-limit, or a dish machine rinse that never came up to heat. Often the cause sits outside the unit, such as a door left open during a delivery, a coil packed with grease, a kitchen far hotter than the maker allows or a booster fed cold water. Checking the door, the coil and the air around the unit is fair; move the product if a cold box stays above 41°F, and book the visit.

Reach-ins, pass-throughs, prep tables and blast chillers: gaskets, hinges, fans, thermostats, condensers and compressors.

A commercial appliance error code appears as letters or numbers on a combi, fryer, reach-in controller, dish machine or laundry machine display, or as a flashing light or an alarm tone.

Randell prep stations that lose temperature over the afternoon are usually visited just before the dinner setup, when the rail can be cleared.

Before you book,
in this order.

Each step comes from Randell's own guidance for Lo on its commercial appliances. Follow it to the end: the last card says whether this is a visit.

01

Check the set point on the control; on an FX drawer, confirm whether it is meant to run as a cooler or a low-temperature drawer.

02

Look for frozen product and move it away from the air outlet.

03

If the set point is right and Lo keeps returning, book a visit.

Still there?

It usually turns into reach-in and prep table repair. Book with the code and the model number.

What not to do

Lo is not a sign of weak cooling. On a Randell FX drawer set anywhere between -5°F and 40°F, what counts as too cold depends on how that drawer is set.

Questions
about Lo.

Can I clear Lo myself?
Check the set point on the control; on an FX drawer, confirm whether it is meant to run as a cooler or a low-temperature drawer. If it comes back, it needs a visit.
Why is my Randell freezing lettuce and showing Lo?
The set point may have been lowered to keep the rail cold. That chills the base too much; reset it and keep the rail covered instead.
Can a Randell FX drawer run as a cooler or a low-temperature drawer?
Yes. Randell describes the FX as two cooling systems in one, from 40°F down to between -5°F and 0°F, or anywhere in between.
Who should change the Randell set point?
The operator manual shows how to adjust it from the keypad. Change it in small steps and check with a thermometer.

Back to your everyday

Still showing Lo?

A booking with a code goes further when it has the code as shown, the model and serial from the data plate, and a word on whether the unit still holds temperature, heats, rinses or spins. With those three, the office can match the likely part to your unit the same day.
