Victory Freezer Error Code Prr: Preheating Alarm
Prr on a Victory FS or FSA freezer is a preheating alarm. The manual lists it without further detail, so the exact trigger is not stated. Note the display and call a technician to confirm the cause.
Low: the manual gives no stop condition, and the freezer is expected to keep running.

What does Victory error code Prr mean?
Prr is the preheating alarm entry in the alarm table for Victory FS and FSA hydrocarbon freezers. The manual lists the code and calls it a preheating alarm. That is all the table says: it adds no description of what is being preheated, no cause, no limit and no action. The Eliwell-type controller raises it, and the table gives the alarm LED, relay, reset type and enabling parameters. Because the manual is this short, this page cannot honestly explain what the controller checks before it shows Prr. The word preheating suggests a warm-up stage, but the document does not say which circuit or temperature it concerns, so nothing more should be assumed. For an operator the practical approach is to note when the alarm appears, whether it follows a power-up or a defrost, and what the cabinet temperature is, then give those details to a technician who can read the controller's parameter list.
Affected models and control systems
Prr is listed for Victory FS and FSA hydrocarbon freezers with an Eliwell-type controller and probes Pb1 to Pb5, in the alarm table on printed pages 18-19. The manual does not tell us which models enable this alarm.
Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.
What you may notice
- Prr on the controller display
- Alarm LED on
- Freezer otherwise running, with no other obvious change
Possible causes
Likely causes — what usually sits behind error code Prr on this control. A technician confirms which one it is before any part is replaced.
- Preheating alarm enabled in the parameters and triggered by a condition the manual does not describe
- Probe reading that is feeding the preheat check out of range
- Recent power interruption that restarted the controller sequence
Safe checks before calling for service
- Check the cabinet temperature and whether the freezer is cooling.
- Note whether Prr appeared after a power interruption or a defrost.
- Do not open panels or change settings.
- See whether Prr stays or clears after several minutes.
- Write down the exact display, any other alarm and when it began; the manual gives no operator action for Prr.
How a technician diagnoses error code Prr
- Read the alarm and history and note other active alarms.
- Find the preheating alarm parameters in the controller list.
- Compare the probe values that feed the check with real temperatures.
- Check supply voltage and recent power events.
- Confirm what the unit's service data says Prr monitors.
- Correct the cause found before any part is replaced.
- Reading the preheating parameters requires service access to the controller.
- Probe and supply checks involve live circuits near a flammable hydrocarbon refrigerant system.
- Because the manual gives no cause, a technician must work out the trigger from the unit's own data.
