Victory Freezer Error Code LPA: Pressure Switch Alarm
LPA on a Victory FS or FSA freezer is a pressure switch alarm, which the manual labels as high pressure. That label looks swapped with HPA, so treat the code as a pressure switch trip and let a technician read the actual pressures.
High: a tripped pressure switch can stop cooling until the pressure cause is found.

What does Victory error code LPA mean?
LPA appears in the Victory FS and FSA alarm table with a label that reads high pressure switch alarm, as printed. The Eliwell-type controller watches a pressure switch on the refrigeration circuit and reports LPA when that switch is active. The manual notes only that the pressure switch alarm is active. The letters LPA would normally suggest low pressure, yet the manual's label says high, and the neighboring HPA is labeled low. That mismatch means the printed labels cannot be trusted to say which side of the system tripped. The table gives no causes, no operator action and no limits; it lists the LED, relay, reset type and enabling parameters only. The sensible reading is that a pressure switch has tripped and that gauge readings will show whether suction or discharge pressure was the cause.
Affected models and control systems
LPA 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 labels for LPA and HPA appear swapped in the manual, so confirm with the unit's own wiring and parameter data.
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
- LPA on the controller display
- Alarm LED on
- Compressor stopped or running in short bursts
Possible causes
Likely causes — what usually sits behind error code LPA on this control. A technician confirms which one it is before any part is replaced.
- Pressure switch tripped on high discharge pressure from a blocked condenser
- Pressure switch tripped on low suction pressure from a restricted or undercharged circuit
- Switch wiring or contact problem making the input look tripped
Safe checks before calling for service
- Check for clear air space around the freezer and an open grille.
- Look from the outside for a heavily dust-covered condenser area.
- Do not open panels, touch the refrigeration lines or reset anything by hand.
- Note whether the compressor is stopped and what the cabinet temperature reads.
- Write down whether LPA, HPA, PA or nPA also appear; the manual's labels conflict, so every code shown helps.
How a technician diagnoses error code LPA
- Read the alarm and note any related pressure alarms.
- Install gauges to read suction and discharge pressure.
- Test the pressure switch at its set point.
- Check condenser airflow and evaporator condition.
- Check the input wiring and the parameter for the pressure input.
- Correct the pressure cause, then confirm LPA clears.
- A flammable hydrocarbon refrigerant circuit needs trained handling and proper gauges.
- Pressure and compressor circuits carry line voltage.
- Because the manual's high and low labels disagree, a technician must read real pressures to know which side tripped.
How error code LPA differs from similar codes
LPA and HPA carry opposite labels from what their letters suggest. The manual prints LPA as high and HPA as low, so the two should be read together.

Does LPA mean low pressure?
The letters suggest it, but the manual prints it as a high pressure switch alarm. Only gauge readings can settle it.
Can I keep running the freezer?
If the compressor has stopped, it is not cooling. Watch product temperature and move food if needed.
Will LPA reset on its own?
The reset type is in the manual's table. Even if it clears, the pressure cause should be found.
