What rSF
actually means.

rSF, log code 31, is the refrigerant leak alarm. Victory's table says it switches off all actuators, so the unit stops cooling. Victory's hydrocarbon units run on a flammable refrigerant, so this alarm deserves care.

What to do when rSF shows on the commercial appliance

Kind of codeCompressor and cooling

The unit is running but not moving heat out of the box the way it should. On a walk-in that is often a condensing unit on the roof choking on cottonwood or grease, a condenser fan that stopped, an evaporator fan or defrost heater that failed so the coil iced solid, or a slow refrigerant leak; a reach-in adds a door gasket or heater that lets warm air in. Cleaning the condenser face with the power off and checking that the doors close are fair first steps; the refrigerant circuit, the compressor and every line stay with a technician.

Usually leads toWalk-in cooler repair

Walk-in coolers and freezers back to temperature: evaporators, fans, defrost, drain heaters, condensing units and doors.

Before you book,
in this order.

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

01

Do not reset rSF repeatedly or open any panel.

02

If you smell gas or hear a hiss, keep flames and switches away, ventilate and move people out of the area.

03

Move food to a working unit and log temperatures.

04

Book a visit; a leak check is technician work.

Still there?

It usually turns into walk-in cooler repair. Book with the code and the model number.

What not to do

rSF is not the high condensing alarm, which is CHt. A reset may restart the unit, but the reason for the alarm stays until it is found.

Questions
about rSF.

Can I clear rSF myself?
Do not reset rSF repeatedly or open any panel. If it comes back, it needs a visit.
Is rSF on my Victory dangerous?
It warns of a possible refrigerant leak. On a hydrocarbon unit, keep ignition sources away and ventilate if you notice any smell.
Can I reset rSF on a Victory myself?
Victory lists it as a manual reset, but resetting without finding the leak only restarts the problem. Book a visit.
Why did my Victory stop completely with rSF?
The control switches off all outputs when this alarm trips, which is by design.

Back to your everyday

Still showing rSF?

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.
