What Hi
actually means.

Randell's 9200 sidemount units and FX drawers use a Danfoss control, and Hi is its high temperature alarm. Randell's table pairs it with two actions: inspect the door and drawer sealing, then contact service. On a sandwich or pizza rail, open covers and empty pan spaces are the everyday reasons it trips.

What to do when Hi 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.

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 Hi on its commercial appliances. Follow it to the end: the last card says whether this is a visit.

01

Probe the pans in the rail and the product in the base, and log both readings.

02

Close the hooded covers, fill every pan space, and check door and drawer gaskets for gaps.

03

Move anything above 41°F to a unit that is holding and follow your health code.

04

If Hi stays after the covers and doors are sorted, 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

Hi does not identify a failed part. On a Randell prep station it is often a rail left open in a hot kitchen, which Randell warns about for rooms above 80°F.

Questions
about Hi.

Can I clear Hi myself?
Probe the pans in the rail and the product in the base, and log both readings. If it comes back, it needs a visit.
Why does my Randell prep table show Hi during lunch?
Open covers and a hot line warm the rail quickly. Randell asks for the covers closed between rushes and every pan in place, with empty ones holding an inch or two of water.
What should I check first when a Randell shows Hi?
Randell's own table says to inspect door and drawer sealing first. A torn gasket or a drawer that does not close fully is common on busy lines.
Is Hi on my Randell an emergency?
If food has been above 41°F, yes: move it before anything else and log what you did.

Back to your everyday

Still showing Hi?

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.
