What r1
actually means.
r1 is the open-circuit reading of the R-sensor. The sensor, its connector or the wire between them has lost continuity. The control no longer has that reading to work with.

What to do when r1 shows on the commercial applianceKind of codeSensors and probes
A probe is handing the controller a reading it cannot trust, or none at all: a box or coil sensor torn loose from its clip, a fryer probe coated in carbon from oil left too long between filterings, a combi core probe with a kinked cable, or a connector gone green from steam and cleaning chemicals. The unit then runs on, stops, or shuts the heat or the cooling off to protect itself. Letting it cool and restarting it as the manual describes is fair; a probe that still reads wrong sits behind a panel, and that is a visit.

Controllers, touch panels, relays, contactors and interlocks tested, and replaced only when the evidence says so.
Shows up asCommercial Appliance Error Code on a Combi, Fryer, Dish Machine or Laundry Display
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.

Before you book,
in this order.
Each step comes from Turbo Air's own guidance for r1 on its commercial appliances. Follow it to the end: the last card says whether this is a visit.
Probe the food and compare it with what the display shows.
Keep doors shut to help the cabinet hold.
Book a visit and quote r1; the connector is the first thing checked.
Still there?
It usually turns into commercial controls and board repair. Book with the code and the model number.
What not to do
r1 is not a real temperature; no cabinet is at -50 degrees. It is the opposite failure to r0.

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.
