Traulsen Refrigerator Error Code ELE LOS: Electrical Loss

What does Traulsen ELE LOS mean?

ELE LOS is short for electrical loss. When the Intela-Traul control powers up after an interruption, it notes that the supply was lost and shows ELE LOS so nobody assumes the cabinet ran steadily the whole time. On newer cabinets the cabinet temperature flashes alternately with ELE LOS as the unit first starts. The message is a notice, not an error by itself. Its practical meaning is that food may have warmed while the cabinet was off, and that the clock and date may need to be set again, especially where defrost lockouts or stored data are in use. Pressing the alarm cancel button clears it. A cabinet that shows ELE LOS repeatedly without an outage in the building is telling you the supply to the cabinet is being interrupted somewhere between the outlet and the control.

Affected models and control systems

Traulsen cabinets with an Intela-Traul control, including TE, TU and TS models and the R and A Series; seen on the TS048HT and RHT132WUT.

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

• ELE LOS shown after the cabinet restarts
• Cabinet temperature flashing alternately with ELE LOS
• Clock or date reset to a default
• Food warmer than normal after a power interruption

Possible causes

Listed in Traulsen's documentation

• A power outage or tripped breaker
• Loose plug or outlet
• A short interruption during a storm
• Clock and date lost if defrost lockouts are used

Other likely causes — what usually sits behind ELE LOS on this control. A technician confirms which one it is before any part is replaced.

• A cord pulled partway out by a cart or by cleaning around the cabinet
• An outlet shared with other kitchen equipment that trips under load
• A switched or GFCI outlet that drops out for a moment

Safe checks before calling for service

How a technician diagnoses ELE LOS

1. Ask when ELE LOS first appeared and compare it with outages or breaker trips.
2. Check the plug, outlet and breaker for a firm fit and proper voltage under load.
3. Measure supply voltage at the cabinet while other kitchen equipment starts.
4. Inspect the cord and its entry to the cabinet for heat marks or a loose strain relief.
5. Confirm the clock, date and any defrost lockout settings after the restart.
6. Repair the supply issue first and watch for a repeat before suspecting the control.
