Randell LEA

What does Randell LEA mean?

On a Randell prep table with the Danfoss controller, LEA is the Continuous Compressor Runtime alarm. It indicates the compressor has been running continuously rather than cycling normally, which usually means the unit cannot reach its set point. The manual's service actions point to a sealing or condenser airflow problem forcing the compressor to run without pause.

Symptoms

• Display shows LEA with the alarm LED lit
• Compressor runs continuously and does not cycle off
• Cabinet struggles to reach or hold the set point
• Door or drawer may not be sealing, or the condenser may be dirty

Common causes

• Door or drawer not sealing, letting warm air in continuously
• Dirty condenser coil reducing cooling capacity
• Heavy or warm product load
• Refrigeration system fault

Diagnostic steps

1. 01

   Confirm the alarm

   Verify the Danfoss display reads LEA, the Continuous Compressor Runtime alarm.

2. 02

   Inspect door and drawer sealing

   The Danfoss table's first action is to inspect door/drawer sealing; close any ajar door and reseat or replace a worn gasket.

3. 03

   Inspect and clean the condenser coil

   The table directs inspecting the condenser coil and cleaning it if necessary so the system can reject heat and let the compressor cycle.

4. 04

   Reduce excess load

   Confirm product was not loaded warm or overloaded, allowing the unit time to pull down to temperature as the manual describes.

5. 05

   Contact service if it persists

   If LEA continues after sealing and condenser checks, the table directs contacting service; call 888-994-7636.

When to call a professional

Owners can address sealing and condenser cleanliness, but continuous compressor runtime that persists points to a refrigeration fault best diagnosed by a professional, and the Danfoss table ends with contacting service. Call a Randell Authorized Service Agent when LEA continues after these checks. The manual requires factory-authorized service with OEM parts on these R290 units; reach service at 888-994-7636.
